Abstract
Purpose This retrospective cohort explores the efficacy of regional shoulder blocks using Exparel™ in patients undergoing total shoulder arthroplasty (TSA)/reverse total shoulder arthroplasty (RSA) to reduce total opioid prescription, refills, and length of stay in the acute care setting. Methods Patients who underwent TSA/RSA by a single surgeon in a three-year period were evaluated. Patients in the case group received liposomal bupivacaine 1.3% brachial plexus block while the control group received ropivacaine 0.5% interscalene brachial plexus block. Outcomes of the study included the number of opioids taken, opioids prescribed, and length of hospital stay. Results Thirty-six patients underwent TSA/RSA between January 2017 and March 2020. Patients who received an Exparel brachial plexus block had decreased opioid use within the first 24 hours after surgery compared to the ropivacaine group, 9.00 ± 14.10 and 26.20 ± 24.8 morphine milligram equivalent (MME), respectively (p=0.0213). Patients who received an Exparel brachial plexus block had decreased opioid prescriptions over the entire postoperative follow-up, 411.00 ± 200.74 MME in the case group and 593.07 ± 297.57 MME in the control group (p=0.0314). Lastly, patients who received an Exparel brachial plexus block had a shorter length of hospital stay, 1.28 ± 0.91 days as compared to the control group's 2.15 ± 1.49 days (p=0.0451). Conclusion This study demonstrates a significant reduction in opioid prescribing and use in patients who receive Exparel brachial plexus nerve blocks compared to non-liposomal local anesthetics, as well as a significant reduction in the length of hospital stay. The data suggest that Exparel use may decrease the risks associated with opioid use while providing adequate analgesia in patients undergoing shoulder arthroplasty.

Abstract
INTRODUCTION Meniscal injuries are a common challenge in orthopedic surgery. For decades, partial or total meniscectomy has been the primary surgical treatment for meniscal tears. In recent years, the increased recognition of menisci's biomechanical importance has progressively shifted the paradigm towards meniscus repair. However, meniscus-sparing surgery remains the treatment of choice for selected lesions in young and active patients, especially for young and active patients. In this study, we evaluated the effectiveness of all-inside sutures in treating meniscus tears in patients over 40. METHODS In our retrospective evaluation, we evaluated the clinical and functional outcomes of cases over 40 years of age with post-traumatic acute meniscus tears that received meniscus repairs using the all-inside technique. The pre-operative and post-operative functionality of treated patients were assessed using the knee injury and osteoarthritis outcome score (KOOS) score. Major complications were recorded. RESULTS Twenty-three cases met our inclusion criteria. Eight females and fifteen males with a mean age of 44.9 were included in our study. Their mean follow-up was 35.1 months. Before surgery, our patients' mean KOOS score was 55.4 (18-80). At the patients' latest follow-up, the value had risen to 87.4 (63-100). There was no statistical correlation between patients' age and their functional recovery. No surgical failure was recorded at the latest follow-up. CONCLUSION The all-inside suture technique can represent a suitable and reliable solution for suturable meniscal tears, even for patients over 40. Preserving the meniscus and restoring patients' functionality allows patients to return to their daily activities and promote their quality of life.

Abstract
Recent advancements in orthopedic surgery have greatly improved the management of musculoskeletal disorders and injuries. This review discusses the latest therapeutic approaches that have emerged in orthopedics. We examine the use of regenerative medicine, including stem cell therapy and platelet-rich plasma (PRP) injections, to accelerate healing and promote tissue regeneration. Additionally, we explore the application of robotic-assisted surgery, which provides greater precision and accuracy during surgical procedures. We also delve into the emergence of personalized medicine, which tailors treatments to individual patients based on their unique genetic and environmental factors. Furthermore, we discuss telemedicine and remote patient monitoring as methods for improving patient outcomes and reducing healthcare costs. Finally, we examine the growing interest in using artificial intelligence and machine learning in orthopedics, particularly in diagnosis and treatment planning. Overall, these advancements in therapeutic approaches have significantly improved patient outcomes, reduced recovery times, and enhanced the overall quality of care in orthopedic surgery.

J Orthop Surg Res 2023; 18:959. [PMID: 38093378 PMCID: PMC10717545 DOI: 10.1186/s13018-023-04435-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 12/01/2023] [Indexed: 12/17/2023] Open
Abstract
BACKGROUND Osteonecrosis of the femoral head (ONFH) is a serious condition that causes bone tissue death, femoral head collapse, and hip joint destruction. Early intervention through hip-preserving treatment is crucial to slow down disease progression, preserve hip joint function, and improve the quality of life of patients. We analyzed the knowledge map, research gaps, and future research directions in the field of hip-preserving treatment for early ONFH. METHODS All publications related to hip-preserving treatment for early ONFH published between 2010 and 2023 were identified from the Web of Science Core Collection and analyzed using VOSviewer 1.6.19, CiteSpace 6.2.R2, and Scimago Graphica 1.0.35. RESULTS In total, 234 articles were analyzed. The results showed an exponential growth trend in the number of publications related to hip-preserving treatment for early ONFH in the past decade. China and the USA were the main contributors. International Orthopaedics published the most papers in this field, whereas Bone and Joint Surgery-American Volume had the highest average citation count per article. Several stable research topics were noted in this field, including core decompression (CD), osteotomy, bone transplantation in hip-preserving surgery, and cell therapy, which have become research hotspots in hip-preserving treatment. CONCLUSIONS Hip-preserving treatment for early ONFH has received increasing attention, and research in this field is expected to grow. Stable research topics include core decompression (CD), osteotomy, bone transplantation, and cell therapy. Future research is predicted to focus on cell therapy and combination therapy, resulting in an increasing number of publications on hip-preserving treatment for early ONFH.

Abstract
Aims The aim of this study was to evaluate the association between chondral injury and interval from anterior cruciate ligament (ACL) tear to surgical reconstruction (ACLr). Methods Between January 2012 and January 2022, 1,840 consecutive ACLrs were performed and included in a single-centre retrospective cohort. Exclusion criteria were partial tears, multiligament knee injuries, prior ipsilateral knee surgery, concomitant unicompartmental knee arthroplasty or high tibial osteotomy, ACL agenesis, and unknown date of tear. A total of 1,317 patients were included in the final analysis, with a median age of 29 years (interquartile range (IQR) 23 to 38). The median preoperative Tegner Activity Score (TAS) was 6 (IQR 6 to 7). Patients were categorized into four groups according to the delay to ACLr: < three months (427; 32%), three to six months (388; 29%), > six to 12 months (248; 19%), and > 12 months (254; 19%). Chondral injury was assessed during arthroscopy using the International Cartilage Regeneration and Joint Preservation Society classification, and its association with delay to ACLr was analyzed using multivariable analysis. Results In the medial compartment, delaying ACLr for more than 12 months was associated with an increased rate (odds ratio (OR) 1.93 (95% confidence interval (CI) 1.27 to 2.95); p = 0.002) and severity (OR 1.23 (95% CI 1.08 to 1.40); p = 0.002) of chondral injuries, compared with < three months, with no association in patients aged > 50 years old. No association was found for shorter delays, but the overall dose-effect analysis was significant for the rate (p = 0.015) and severity (p = 0.026) of medial chondral injuries. Increased TAS was associated with a significantly reduced rate (OR 0.88 (95% CI 0.78 to 0.99); p = 0.036) and severity (OR 0.96 (95% CI 0.92 to 0.99); p = 0.017) of medial chondral injuries. In the lateral compartment, no association was found between delay and chondral injuries. Conclusion Delay was associated with an increased rate and severity of medial chondral injuries in a dose-effect fashion, in particular for delays > 12 months. Younger patients seem to be at higher risk of chondral injury when delaying surgery. The timing of ACLr should be optimally reduced in this population.

Abstract
Meniscal extrusion (ME) is strongly correlated with cartilage wear and osteoarthritis (OA), be-cause of the altered kinematic and the decreased contact area between the tibia and femur. The aim of this narrative review is to analyze the process of ME, focusing on the possible causes, and to evaluate the correlation between ME and knee OA, in order to provide early diagnosis and treatments. Studies written in English that analyzed the causes of ME, provided indications re-garding diagnosis and treatment, and evaluated the relation between ME and early OA were in-cluded. Injuries, degeneration of the meniscal substance and meniscus root tears are associated with significantly increased ME. An extruded meniscus could be a manifestation of other pa-thologies such as disruption of coronary ligaments, cartilage loss, knee malalignment, ligament injuries, or OA. ME is strongly associated with osteoarthritis features, particularly with bone marrow lesion and cartilage damage. Magnetic resonance imaging represents the gold standard for the detection of ME. The severity of the medial meniscus extrusion may also affect healing af-ter repair, and meniscus extrusion is not completely reduced by meniscus posterior root tear re-pair. In this study, we proved that ME represents an important risk factor for early knee OA. We provided alternative theories of ME, such as meniscal fibers injury first and "dynamic extrusion of the menisci". The phenomenon of aging has been described as a new concept in the etiology of ME. Finally, we stated all the main techniques and characteristics of the diagnostic process, as well as the current knowledge in the therapeutic field.

Abstract
Over the years, several studies demonstrated the crucial role of knee menisci in joint biomechanics. As a result, save the meniscus has become the new imperative nowadays, and more and more studies addressed this topic. The huge amount of data on this topic may create confusion in those who want to approach this surgery. The aim of this review is to provide a practical guide for treatment of meniscus tears, including an overview of technical aspects, outcomes in the literature and personal tips. Taking inspiration from a famous movie directed by Sergio Leone in 1966, the authors classified meniscus tears in three categories: The good, the bad and the ugly lesions. The inclusion in each group was determined by the lesion pattern, its biomechanical effects on knee joint, the technical challenge, and prognosis. This classification is not intended to substitute the currently proposed classifications on meniscus tears but aims at offering a reader-friendly narrative review of an otherwise difficult topic. Furthermore, the authors provide a concise premise to deal with some aspects of menisci phylogeny, anatomy and biomechanics.

Abstract
PURPOSE Trainee involvement in patient care has raised concerns about the potential risk of adverse outcomes and harming patients. We sought to analyze the impact and potential consequence of surgical trainee involvement in total knee arthroplasty (TKA) procedures in terms of surgical efficacy, patient safety, and functional outcomes. METHODS We systematically reviewed Medline/PubMed, EMBASE, the Cochrane library, and Scopus databases in April 2021. Eligible studies reported on the impact of trainee participation in TKA procedures performed with and without such involvement. RESULTS Twenty-three publications met our eligibility criteria and were included in our study. These studies reported on 132,624 surgeries completed on 132,416 patients. Specifically, 23,988 and 108,636 TKAs were performed with and without trainee involvement, respectively. The mean operative times for procedures with (n = 19,573) and without (n = 94,581) trainee involvement were 99.77 and 85.05 min, respectively. Both studies that reported data on cost of TKAs indicated a significant increase (p < 0.001) associated with procedures completed by teaching hospitals compared to private practices. Mean overall complication rates were 7.20% and 7.36% for TKAs performed with (n = 9,386) and without (n = 31,406) trainees. Lastly, the mean Knee Society Scale (KSS) knee scores for TKAs with (n = 478) and without (n = 806) trainee involvement were similar; 82.81 and 82.71, respectively. CONCLUSION Our systematic review concurred with previous studies that reported trainee involvement during TKAs increases the mean operative time. However, the overall complication rates and functional outcomes were similar. Larger studies with a better methodology and higher level of evidence are still needed for a resolute conclusion.

Meniscal Injuries in Patients Aged 40 Years or Older: A Comparative Study Between Meniscal Repair and Partial Meniscectomy. Cureus 2023; 15:e33270.

Abstract
Introduction Meniscal tears represent one of the most frequent knee injuries and are the most common cause of knee surgery. Historically, age has been considered an independent factor contraindicating meniscal repair due to the assumption that meniscal injuries in this population are frequently chronic tears, mostly with a degenerative tear pattern, and low healing potential. However, recent literature has questioned this paradigm with studies reporting successful outcomes with meniscal repair in older patients. Our study aimed to evaluate and compare the short-term clinical outcomes of meniscal repair versus partial meniscectomy in patients aged ≥40 years old. Methods A retrospective study was conducted that included patients over the age of 40 years, diagnosed with meniscal tears, that underwent arthroscopically assisted meniscal repair or partial meniscectomy between 01 January and 31 December 2020. The patients were divided into two groups: Group 1- partial meniscectomy (PM) and Group 2- meniscal repair (MR). The clinical evaluation was performed 24 months after the surgery, and the studied variables were: function (Tegner Lysholm Knee Scoring Scale), pain (Visual Analogue Scale), patient satisfaction, and failure rate. Results Fifty-one patients met the inclusion criteria, and 7 were excluded due to loss of follow-up during telephone contact. Thus, the final sample consisted of 44 patients (mean age 52.18y), both groups with 22 patients. In both groups, we found an improvement in pain 2 years after the surgery, with a decrease in the VAS value between the pre and post-surgery. On average, the VAS score decreased from 7.9 to 4.5 in the group subjected to partial meniscectomy, and from 7.5 to 3.2 in the meniscal repair. This was statistically significant in both groups, with a p-value <0.01, but not between them (p-value = 0.363). Comparing the degree of satisfaction between both groups, we found no statistically significant difference between them (p=0.167). Regarding the functional outcome (Tegner Lysholm Knee Scoring Scale), the group that underwent the meniscal repair obtained a statistically superior score compared to the partial meniscectomy group (77.55 vs. 64.77; p-value 0.033). The failure rate was exactly equal in both groups (4.5%), therefore no statistically significant difference was found in this variable. Conclusion Age, as an independent factor, should not be considered a contraindication for meniscus repair. In fact, if technically possible, meniscal repair should always be performed as it is associated with better functional outcomes, similar failure rates, and may be protective against the development and progression of arthritis.

Abstract
This a case report of a 40-year-old male with left knee dislocation Type III and associated peroneal nerve palsy underwent delayed allograft reconstruction of his multiligament knee injury (MKI) with Internal Brace augmentation. The patient returned to work at 6 months postoperatively. He then fell and sustained a displaced supracondylar left femur fracture at the site of the internal brace augmentation of his lateral collateral ligament (LCL) reconstruction for which he underwent placement of a retrograde femoral nail. At 2 years of follow-up the patient had no evidence of knee instability. Level of evidence: V.

Abstract
BACKGROUND This study aimed to evaluate the efficacy of viscosupplementation after arthroscopic partial meniscectomy. METHOD A randomized controlled trial of 47 patients who underwent arthroscopic partial meniscectomy was conducted between March 2020 and March 2021. Patients were randomized into two groups: a viscosupplementation group (n = 23) and a control group (n = 24). A single-dose intraarticular hyaluronic acid injection was used as viscosupplementation. The 100 mm visual analogue scale (VAS) for pain assessment was measured at baseline and at 1 day, 2 weeks, 6 weeks, and 3 months post-surgery. The International Knee Documentation Committee (IKDC), Tegner, Lysholm, and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scores and range of motion (ROM) of the knee were measured at baseline, 2 weeks, 6 weeks, and 3 months. RESULTS The 100 mm VAS score for pain was significantly lower in the viscosupplementation group at 2 weeks post-surgery (27.5 mm vs. 40.7 mm, P = 0.047). ROM was significantly greater in the viscosupplementation group than in the control group at 2 weeks (131.5° vs. 121.0°, P = 0.044) post-surgery. No significant differences were observed in the IKDC or in the Tegner, Lysholm, and WOMAC scores between the two groups. CONCLUSIONS Viscosupplementation after arthroscopic partial meniscectomy significantly reduced pain at 2 weeks post-surgery and improved ROM of the knee at 2 weeks post-surgery. There might be some benefits in terms of pain and functional recovery of viscosupplementation after arthroscopic surgery. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. TRIAL REGISTRATION This randomized controlled trial was registered at cris.nih.go.kr # KCT0004921 .

Abstract
Complete access to the posterior medial compartment of the knee may represent a technical challenge during arthroscopy in patients with a tight tibiofemoral joint space. Medial collateral release reduces direct iatrogenic cartilage damage in the medial compartment of the knee through manipulation with instruments. We recommend performing medial collateral release in surgeries that access the posteromedial compartment (e.g. partial meniscectomy for ruptures of the posterior horn of medial meniscus or posterior root repairs) when the patient has a tight tibiofemoral joint space. There are two main techniques to perform medial collateral release: inside-out and outside-in. Regardless of the technique used, releasing medial ligament structures is a safe and effective method to be used in the diagnosis and treatment of injuries to the medial compartment.

Perspectives on the Gamification of an Interactive Health Technology for Postoperative Rehabilitation of Pediatric Anterior Cruciate Ligament Reconstruction: User-Centered Design Approach. JMIR Serious Games 2021; 9:e27195. [PMID: 34448715 PMCID: PMC8433934 DOI: 10.2196/27195] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Revised: 04/29/2021] [Accepted: 05/24/2021] [Indexed: 11/26/2022] Open
Abstract
Background Pediatric and adolescent athletes are a large demographic undergoing anterior cruciate ligament reconstruction (ACL-R). Postoperative rehabilitation is critical, requiring patients to complete home exercise programs (HEPs). To address obstacles to HEP adherence, we developed an interactive health technology, interACTION (iA), to monitor knee-specific rehabilitation. iA is a web-based platform that incorporates wearable motion sensors and a mobile app that provides feedback and allows remote monitoring. The Wheel of Sukr is a gamification mechanism that includes numerous behavioral elements. Objective This study aims to use a user-centered design process to incorporate behavioral change strategies derived from self-management theory into iA using the Wheel of Sukr, with the aim of influencing patient behavior. Methods In total, 10 athletes aged 10-18 years with a history of ACL-R were included in this study. Patients were between 4 weeks and 1 year post–ACL-R. Participants underwent a 60-minute triphasic interview. Phase 1 focused on elements of gaming that led to high participation and information regarding surgery and recovery. In phase 2, participants were asked to think aloud and rank cards representing the components of the Wheel of Sukr in order of interest. In phase 3, the patients reviewed the current version of iA. Interviews were recorded, transcribed, and checked for accuracy. Qualitative content analysis segmented the data and tagged meaningful codes until descriptive redundancy was achieved; next, 2 coders independently coded the data set. These elements were categorized according to the Wheel of Sukr framework. The mean age of participants was 12.8 (SD 1.32) years, and 70% (7/10) were female. Most participants (7/10, 70%) reported attending sessions twice weekly. All patients were prescribed home exercises. Self-reported HEP compliance was 75%-100% in 40% (4/10), 50%-75% in 40% (4/10), and 25%-50% of prescribed exercises in 20% (2/10) of the participants. Results The participants responded positively to an app that could track home exercises. Desirable features included exercise demonstrations, motivational components, and convenience. The participants listed sports specificity, competition, notifications, reminders, rewards, and social aspects of gameplay as features to incorporate. In the Wheel of Sukr card sort exercise, motivation was ranked first; self-management, second; and growth, esteem, and fun tied for the third position. The recommended gameplay components closely followed the themes from the Wheel of Sukr card sort activity. Conclusions The participants believe iA is a helpful addition to recovery and want the app to include exercise movement tracking and encouragement. Despite the small number of participants, thematic saturation was reached, suggesting the sample was sufficient to obtain a representative range of perspectives. Future work will implement motivation; self-management; and growth, confidence, and fun in the iA user experience. Young athlete ACL-R patients will complete typical clinical scenarios using increasingly developed prototypes of the gamified iA in a controlled setting.

Abstract
This study aimed to analyze the rates and risk factors of postoperative mortality among 560,954 patients who underwent total knee arthroplasty (TKA) in Korea. The National Health Insurance Service-Health Screening database was used to analyze 560,954 patients who underwent TKA between 2005 and 2018. In-hospital, ninety-day, and one-year postoperative mortality, and their association with patient’s demographic factors and various comorbidities (ie., cerebrovascular disease, congestive heart failure, and myocardial infarction) were assessed. In-hospital, ninety-day and one-year mortality rates after TKA were similar from 2005 to 2018. The risk of in-hospital mortality increased with comorbidities like cerebrovascular disease (hazard ratio [HR] = 1.401; 95% confidence interval [CI] = 1.064–1.844), congestive heart failure (HR = 2.004; 95% CI = 1.394 to 2.881), myocardial infarction (HR = 2.111; 95% CI = 1.115 to 3.998), and renal disease (HR = 2.641; 95% CI = 1.348–5.173). These co-morbidities were also independent predictors of ninety-day and one-year mortality. Male sex and old age were independent predictors for ninety-day and one-year mortality. And malignancy was risk factor for one-year mortality. The common preoperative risk factors for mortality in all periods were male sex, old age, cerebrovascular disease, congestive heart failure, myocardial infarction, and renal disease. Malignancy was identified as risk factor for one-year mortality. Patients with these comorbidities should be provided better perioperative care.

Abstract
Background Surgical treatment of insertional Achilles tendinopathy with Haglund deformity in highly competitive professional athletes has not been previously investigated. Purpose To assess clinical outcomes, including return to play (RTP), after surgical treatment of insertional Achilles tendinopathy in professional athletes. Study Design Case-control study; Level of evidence, 3. Methods This retrospective study included 20 professional athletes who were surgically treated for insertional Achilles tendinopathy and had at least 2 years of follow-up. An open longitudinal lateral approach was used for the operation, without violation of the Achilles tendon. Outcome evaluation included American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, subjective patient satisfaction, mean time of return to competition (RTC), and rate of RTP. We defined RTC as return to an official match for at least 1 minute and RTP rate as the percentage of patients who were able to participate in at least 2 full seasons. A subgroup analysis was performed to compare the RTP and no-RTP groups. Results The AOFAS score improved significantly from preoperatively to the final follow-up (from 65.1 to 88.4; P < .001), and 75% of the patients reported good to excellent satisfaction. The mean time of RTC was 7.45 months (range, 4-18 months), and the rate of RTP was 60%. The RTP group had a significantly lower mean body mass index than did the no-RTP group (22.03 vs 23.86, respectively; P = .005) and faster mean RTC (5.0 vs 11.1 months, respectively; P < .001). Conclusion Open calcaneoplasty for surgical treatment of insertional Achilles tendinopathy with Haglund deformity in highly competitive professional athletes should be approached cautiously. Our patients had a 7.5-month recovery period before return to their first official match, and only 60% of the patients returned to their sports activity and participated in at least 2 full seasons. Lower body mass index and a faster RTC after surgery were related to longer functional maintenance.

Abstract
Purpose The aim of this study was to verify the effects of a new remnant augmentation technique with anatomical double-bundle anterior cruciate ligament (ACL) reconstruction for postoperative clinical scores, anterior stability and frequency of complications compared to remnant removal and cases with remnant defects. Methods The 105 patients who underwent anatomical double-bundle ACL reconstruction were divided into three groups. If the remnant was a Crain I-III type, remnant-preserving bone tunnel creation was attempted. After the creation of the bone tunnel, good continuity was maintained in 34 patients (preserved group). Due to lost continuity, the remnant was resected in 26 patients (resected group). No identifiable remnant continuity remained (Crain IV) in 45 patients (absent group). The Lysholm knee score, Tegner activity scale, International Knee Documentation Committee (IKDC) subjective score, anterior stability measured using the KT-1000 arthrometer at 2 years postoperatively, and frequency of complications were compared among the three groups. Univariate and multiple linear regression analysis were performed to clarify the factors affecting postoperative anterior stability. Results The Lysholm knee score, Tegner activity scale, IKDC subjective score, and frequency of complications were not significantly different among the groups. The mean side-to-side difference of anterior stability was significantly better in the preserved group (0.3 ± 1.6 mm) compared to the resected group (1.6 ± 2.3 mm, p = 0.003) and absent group (1.6 mm ± 1.7, p = 0.009). The multiple linear regression analysis showed remnant preservation significantly related to postoperative anterior stability. Conclusion Although there were no differences in clinical scores, the ACL reconstruction with new preservation technique showed good anterior stability and no difference in the frequency of complications.

Orthop J Sports Med 2021; 9:23259671211003873. [PMID: 33997080 PMCID: PMC8113660 DOI: 10.1177/23259671211003873] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Accepted: 11/23/2020] [Indexed: 01/22/2023] Open
Abstract
Background: Previous simulation studies evaluated either dry lab (DL) or virtual reality (VR) simulation, correlating simulator training with the performance of arthroscopic tasks. However, these studies did not compare simulation training with specific surgical procedures. Purpose/Hypothesis: To determine the effectiveness of a shoulder arthroscopy simulator program in improving performance during arthroscopic anterior labral repair. It was hypothesized that both DL and VR simulation methods would improve procedure performance; however, VR simulation would be more effective based on the validated Arthroscopic Surgery Skill Evaluation Tool (ASSET) Global Rating Scale. Study Design: Controlled laboratory study. Methods: Enrolled in the study were 38 orthopaedic residents at a single institution, postgraduate years (PGYs) 1 to 5. Each resident completed a pretest shoulder stabilization procedure on a cadaveric model and was then randomized into 1 of 2 groups: VR or DL simulation. Participants then underwent a 4-week arthroscopy simulation program and completed a posttest. Sports medicine–trained orthopaedic surgeons graded the participants on completeness of the surgical repair at the time of the procedure, and a single, blinded orthopaedic surgeon, using the ASSET Global Rating Scale, graded participants’ arthroscopy skills. The procedure step and ASSET grades were compared between simulator groups and between PGYs using paired t tests. Results: There was no significant difference between the groups in pretest performance in either the procedural steps or ASSET scores. Overall procedural step scores improved after combining both types of simulator training (P = .0424) but not in the individual simulation groups. The ASSET scores improved across both DL (P = .0045) and VR (P = .0003), with no significant difference between the groups. Conclusion: A 4-week simulation program can improve arthroscopic skills and performance during a specific surgical procedure. This study provides additional evidence regarding the benefits of simulator training in orthopaedic surgery for both novice and experienced arthroscopic surgeons. There was no statistically significant difference between the VR and DL models, which disproved the authors’ hypothesis that the VR simulator would be the more effective simulation tool. Clinical Relevance: There may be a role for simulator training in the teaching of arthroscopic skills and learning of specific surgical procedures.

Abstract
To compare the postoperative effects of arthroscopy for rotator cuff injury with patients in the lateral-lying position (LLP) and beach chair position (BCP), and to identify factors influencing these effects.Data from patients with rotator cuff injuries who underwent shoulder arthroscopy in the LLP (n = 115, 53.24%) or BCP (n = 101, 46.76%) between January 2013 and 2016 and were followed for >3 years were analyzed. The American Shoulder and Elbow Surgeons shoulder score, University of California at Los Angeles shoulder score (UCLASS), and visual analog scale (VAS) score were used to evaluate patients' shoulder function and pain preoperatively and at the last follow-up examination. The abduction and lateral rotation angles were measured. The influences of patient characteristics were compared between the LLP and BCP subgroups defined by UCLASSs (excellent, good, acceptable, poor).Postoperative injury characteristics, UCLASSs, and VAS scores were better in the LLP group than in the BCP group (all P < .05). Among patients with good UCLASSs, preoperative pain duration was longer in the LLP group than in the BCP group (P < .05); among those with acceptable UCLASSs, this duration was longer in the BCP group than in the LLP group (P < .05). The preoperative flexion angle differed between groups (P < .05). Among patients with excellent and good UCLASSs, the postoperative external rotation angle was greater in the LLP group than in the BCP group (P < .05). The LLP group contained more excellent UCLASSs than did the BCP group (P < .05). It also contained more small, medium, and large tear cases than did the BCP group (all P < .05).The effect of arthroscopy for rotator cuff injury was better when the operation was performed with the patient in the LLP. Either position is suitable for the arthroscopic treatment of partial rotator cuff tears. The LLP is more suitable in cases of small and medium-sized tears and those with large preoperative lateral rotation angles. The BCP should be used for patients with large preoperative flexion angles.

Abstract
IMPORTANCE Arthroscopic meniscectomy is one of the most common orthopedic procedures. The optimal postoperative approach remains debated. OBJECTIVE To compare outcomes associated with home-based rehabilitation programs (HBP) vs standard inpatient and/or outpatient supervised physical therapy (IOP) following arthroscopic isolated meniscectomy (AM). DATA SOURCES A systematic literature search was conducted on PubMed, Web of Science, Cochrane Library, and Scopus databases on March 15, 2021. The included studies were published from 1982 to 2019. STUDY SELECTION Randomized clinical trials of patients treated with HBP vs IOP after AM were included. DATA EXTRACTION AND SYNTHESIS Data were independently screened and extracted by 2 authors according to the Preferred Reporting Items for Systematic Reviews (PRISMA) reporting guideline. The meta-analysis was performed using a random-effect model; when an I2 < 25% was observed, the fixed-effect model was used. The Hartung-Knapp correction was applied. MAIN OUTCOMES AND MEASURES The primary outcome was the Lysholm score (scale of 0-100 with higher scores indicating better knee function) and secondary outcomes were subjective International Knee Documentation Committee (IKDC) score, knee extension and flexion, thigh girth, horizontal and vertical hop test, and days to return to work, as indicated in the PROSPERO registration. Outcomes were measured in the short-term (ranging from 28 to 50 days) and the midterm (6 months). RESULTS In this meta-analysis of 8 RCTs including 434 patients, IOP was associated with a greater short-term improvement in Lysholm score compared with HBP, with a mean difference of -8.64 points (95% CI, -15.14 to -2.13 points; P = .02) between the 2 approached, but the sensitivity analysis showed no difference. Similarly, no statistically significant difference was detected at midterm for Lysholm score, with a mean difference between groups of -4.78 points (95% CI, -9.98 to 0.42 points; P = .07). HBP was associated with a greater short-term improvement in thigh girth, with a mean difference between groups of 1.38 cm (95% CI, 0.27 to 2.48 cm; P = .01), whereas IOP was associated with a better short-term vertical hop score, with a mean difference between groups of -3.25 cm (95% CI, -6.20 to -0.29 cm; P = .03). No differences were found for all the other secondary outcomes. CONCLUSIONS AND RELEVANCE No intervention was found to be superior in terms of physical and functional outcomes as well as work-related and patient-reported outcomes, both at short-term and midterm follow-up. Overall, these results suggest that HBP may be an effective management approach after AM in the general population.

[PMID: 33307179 PMCID: PMC8051641 DOI: 10.1016/j.joca.2020.11.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 11/20/2020] [Accepted: 11/27/2020] [Indexed: 02/02/2023]
Abstract
Injury to the meniscus is common and frequently leads to the development of post-traumatic osteoarthritis (PTOA). Many times meniscus injuries occur coincident with anterior cruciate ligament (ACL) injuries and lead to a bloody joint effusion. Hemarthrosis, or bleeding into the joint, has been implicated in degeneration of joint tissues. The goal of this review paper is to understand the pathophysiology of blood-induced joint damage, the possible effects of blood on meniscus tissue, and the implications for current meniscus repair techniques that involve the introduction of blood-derived products into the joint. In this review, we illustrate the similarities in the pathophysiology of joint damage due to hemophilic arthropathy (HA) and osteoarthritis (OA). Although numerous studies have revealed the harmful effects of blood on cartilage and synovium, there is currently a gap in knowledge regarding the effects of hemarthrosis on meniscus tissue homeostasis, healing, and the development of PTOA following meniscus injury. Given that many meniscus repair techniques utilize blood-derived and marrow-derived products, it is essential to understand the effects of these factors on meniscus tissue and the whole joint organ to develop improved strategies to promote meniscus tissue repair and prevent PTOA development.

Certificate-of-Need Programs Are Associated with a Reduced Incidence, Expenditure, and Rate of Complications with Respect to Knee Arthroscopy in the Medicare Population. HSS J 2020; 16:264-271. [PMID: 33380956 PMCID: PMC7749925 DOI: 10.1007/s11420-019-09693-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2019] [Accepted: 04/30/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND To curb costs at the state level, improve care quality, and promote access to care, certificate-of-need (CON) laws were established in many states in 1974. It is not known how CON regulations have affected the provision of knee arthroscopy, one of the most common orthopedic procedures performed in the USA. QUESTIONS/PURPOSES We sought to characterize the effects of CON regulations on knee arthroscopy in the national Medicare population by examining trends in procedure volumes, comparing trends in procedure charges, evaluating distribution of procedure volumes between high-, mid-, and low-volume facilities, and comparing adverse event and complication rates after knee arthroscopy between states with and without CON regulations. METHODS States with CON regulations covering both inpatient and outpatient operating rooms formed the study group (n = 25 states) and were compared with states without CON laws or laws that did not cover operating rooms during the study period (n = 20 states). The 100% Medicare Standard Analytical Files from 2005 through 2014 were used to compare knee arthroscopy procedure volumes, charges, reimbursements, distribution of procedures based on facility volumes and adverse events between the two groups. RESULTS The rate of decrease in the incidence of knee arthroscopy was significantly greater in CON states than that in non-CON states. CON states also had significantly lower charges at all time points, and overall, compared with non-CON states. There were significantly more high- and mid-volume facilities in CON states than in non-CON states, and there were significantly more low-volume facilities in non-CON states than in CON states. Finally, there were significantly higher rates of emergency room visits within 30 days and infection within 6 months in non-CON states than in CON states. CONCLUSIONS CON regulations appear to have achieved several of their intended goals for knee arthroscopy. Further research is needed to determine if CON regulations affect the quality and sustainability of care provided to patients undergoing knee arthroscopy.

Platelet-Rich Plasma Augmentation for Isolated Arthroscopic Meniscal Repairs Leads to Significantly Lower Failure Rates: A Systematic Review of Comparative Studies. Orthop J Sports Med 2020; 8:2325967120964534. [PMID: 33283008 PMCID: PMC7682240 DOI: 10.1177/2325967120964534] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 06/08/2020] [Indexed: 01/23/2023] Open
Abstract
Background: Studies have reported relatively high failure rates of isolated meniscal repairs. Platelet-rich plasma (PRP) has been suggested as a way to increase growth factors that enhance healing. Purpose: To compare (1) meniscal repair failures and (2) patient-reported outcomes after isolated arthroscopic meniscal repair augmented with and without PRP. Study Design: Systematic review; Level of evidence, 3. Methods: A systematic review was performed using the PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines. Multiple databases were searched for studies that compared outcomes of isolated arthroscopic meniscal repair augmented with PRP versus without PRP in human patients. Failures and patient-reported outcome scores were reported for each study and compared between groups. Study heterogeneity was assessed using I2 for each outcome measure before meta-analysis. Study methodological quality was analyzed. Continuous variable data were reported as mean and standard deviation from the mean. Categorical variable data were reported as frequency with percentage. All P values were reported with significance set at P < .05. Results: Five articles were analyzed (274 patients [110 with PRP and 164 without PRP]; 65.8% male; mean age, 29.1 ± 4.6 years; mean follow-up, 29.2 ± 22.1 months). The risk of meniscal repair failure ranged from 4.4% to 26.7% for PRP-augmented repairs and 13.3% to 50.0% for repairs without PRP. Meniscal repairs augmented with PRP had significantly lower failure rates than repairs without PRP (odds ratio, 0.32; 95% CI, 0.12-0.90; P = .03). One of the 5 studies reported significantly higher outcomes in the PRP-augmented group versus the no-PRP group for the International Knee Documentation Committee (IKDC), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Knee injury and Osteoarthritis Outcome Score (KOOS) (P < .05 for all). The remaining 4 studies reported no significant difference between groups with regard to outcomes for the IKDC, Lysholm knee scale, visual analog scale for pain, or Tegner activity level. Conclusion: Although the studies were of mostly of low quality, isolated arthroscopic meniscal repairs augmented with PRP led to significantly lower failure rates (10.8% vs 27.0%; odds ratio, 0.32; P = .03) as compared with repairs without PRP. However, most studies reported no significant differences in patient-reported outcomes.

Gene Expression in Meniscal Tears at the Time of Arthroscopic Partial Meniscectomy Predicts the Progression of Osteoarthritis Within 6 Years of Surgery. Orthop J Sports Med 2020; 8:2325967120936275. [PMID: 32923494 PMCID: PMC7446268 DOI: 10.1177/2325967120936275] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Accepted: 12/23/2019] [Indexed: 12/13/2022] Open
Abstract
Background: While knees with meniscal tears are associated with a heightened risk of developing osteoarthritis (OA), it is difficult to predict which patients are at the greatest risk for OA. Gene signatures in menisci that are resected during arthroscopic partial meniscectomy (APM) may provide insight into the risk of OA progression. Hypothesis: Meniscal gene signatures at the time of APM will predict radiographic OA progression. Study Design: Case series; Level of evidence, 4. Methods: Meniscal fragments were collected from 38 patients without OA during clinically indicated APM of the medial meniscus. The expression of 28 candidate genes with known roles in cartilage homeostasis, OA, extracellular matrix degradation, and obesity was assessed by quantitative real-time polymerase chain reaction. Weightbearing radiographs obtained before surgery and at final follow-up were graded by a musculoskeletal radiologist using the Kellgren-Lawrence classification of OA. The association of meniscal gene expression at baseline with the progression of radiographic OA was determined. Results: Gene expression and baseline and follow-up radiographic data were available from 31 patients (81.6%) at a mean follow-up of 6.2 ± 1.3 years. Patients without OA progression had significantly higher expression of 7 genes: MMP9 (5.1-fold; P = .002), IL8 (2.9-fold; P = .016), CCL3 (3.7-fold; P = .032), CCL3L1 (4.5-fold; P = .008), CXCL6 (6.2-fold; P = .010), LEP (5.2-fold; P = .004), and RETN (46-fold; P = .008). Conclusion: Gene expression in the meniscus at the time of APM may be associated with the risk for progression of OA after surgery. Elevated expression of the aforementioned genes may reflect a chondroprotective response. Stratifying the risk for OA progression after APM could facilitate targeted interventions to delay or prevent the development of OA. Further studies in a larger cohort with an extended follow-up, and inclusion of additional genes, are warranted to better characterize this association.

Intra-Articular Injection of Stromal Cell-Derived Factor 1α Promotes Meniscal Healing via Macrophage and Mesenchymal Stem Cell Accumulation in a Rat Meniscal Defect Model. Int J Mol Sci 2020; 21:ijms21155454.

Abstract
The stromal-cell-derived factor-1α (SDF-1) is well-known for playing important roles in the regeneration of tissue by enhancing cell migration. However, the effect of SDF-1 in meniscal healing remains unknown. The purpose of this study is to investigate the effects of intra-articular injection of SDF-1 on meniscus healing in a rat meniscal defect model. The intra-articular SDF-1 injection was performed at meniscectomy and one week later. Macroscopic and histological assessments of the reparative meniscus were conducted at one, two and six weeks after meniscectomy in rats. In the macroscopic evaluation, the SDF-1 group showed an increase in the size of the reparative meniscus at six weeks after meniscectomy compared to the phosphate-buffered saline (PBS) injection (no-treatment) group. Histological findings showed that intra-articular injection of SDF-1 enhanced the migration of macrophages to the site of the regenerative meniscus at one and two weeks after meniscectomy. CD68- and CD163-positive cells in the SDF-1 group at one week after meniscectomy were significantly higher than in the no-treatment group. CD163-positive cells in the SDF-1 group at two weeks were significantly higher than in the no-treatment group. At one week after meniscectomy, there were cells expressing mesenchymal-stem-cell-related markers in the SDF-1 group. These results indicate the potential of regenerative healing of the meniscus by SDF-1 injection via macrophage and mesenchymal stem cell accumulation. In the present study, intra-articular administration of SDF-1 contributed to meniscal healing via macrophage, CD90-positive cell and CD105-positive cell accumulation in a rat meniscal defect model. The SDF-1–CXCR4 pathway plays an important role in the meniscal healing process. For potential clinical translation, SDF-1 injection therapy seems to be a promising approach for the biological augmentation in meniscal injury areas to enhance healing capacity.

Percutaneous Partial Outside-In Release of Medial Collateral Ligament for Arthroscopic Medial Meniscus Surgery With Tight Medial Compartment by Finding a "Magic Point".

Abstract
The medial meniscus is one of the more commonly injured structures as compared with the lateral meniscus. In patients with tight medial joint space, it is difficult to visualize the posterior horn and posterior root of medial meniscus and even more difficult to use instrumentation for surgical procedures. Normally, the mean medial joint space (4.74 ± 0.75 mm) is less than the mean lateral joint space width (5.63 ± 0.86). Forceful instrumentation in a tight and a narrow medial joint compartment may cause damage to the articular cartilage, which may increase chances of arthritis in future. To increase the opening of the medial compartment after valgus extension stress position of the knee, different techniques of medial collateral ligament release have been described in the literature. However, the majority of articles describe a multiple-puncture method to the medial collateral ligament called the "pie-crusting" method, not explaining the exact point or precise location of release. Here, we describe a simple and reliable method of medial collateral ligament release by finding the exact release point, a "magic point" to increase the medial joint compartment width to facilitate better visualization and instrumentation for surgical procedures.

Abstract
While there is emerging data on how duration of symptoms prior to surgery relates to outcomes of patients undergoing arthroscopic partial meniscectomy, little is known about how duration of symptoms relates to the biology of the knee in these patients. The purpose of this study was to test the hypothesis that duration of symptoms prior to arthroscopic partial meniscectomy is associated with expression of osteoarthritis (OA)-related genes in the meniscus. We collected resected meniscus from patients (N = 76) undergoing clinically indicated arthroscopic partial meniscectomy from knees without advanced degenerative changes. RNA from 64 patients was analyzed for 28 candidate OA transcripts by real-time polymerase chain reaction (PCR). RNA was also probed for identification of novel genes by RNA microarray in 12 patients followed by validation of selected candidates by real-time PCR. The association of gene expression with duration of symptoms prior to surgery was tested. Additional screening was performed with known OA genetic risk alleles assembled from published literature and with gene transcripts differentially expressed between non-OA and OA cartilage and menisci. Our data revealed that duration of symptoms did not predict expression of OA genes in the meniscus, other than limited association with CXCL3, BMP2, and HLA-DQA1. Microarray identified new genes and pathways with unknown role(s) in meniscus injury and OA and validation of a subset of genes by real-time PCR showed expression pattern highly concordant with the microarray data. While duration of symptoms prior to arthroscopic partial meniscectomy does not significantly alter the expression of OA related genes, the association with novel genes and pathways deserves further investigation.

Abstract
Background Focal cartilage defects (FCDs) in the knee joint has a high prevalence. A broad range of treatment options exists for symptomatic patients. Knowledge of patient compensation claims following surgical treatment of FCDs is missing. The purpose of this study is to evaluate compensation claims filed to the Scandinavian registries for patient compensation following treatment of FCDs in the knee joint from 2010 to 2015 and identify possible areas of improvement. Methods A cross-sectional study design was used to obtain all complaints following surgical treatment of FCDs from the Scandinavian registries from 2010 to 2015. Data such as age, gender, type of treatment, type of complaint, reason of verdict and amount of compensation were collected and systematically analyzed. Results 103 patients filed a compensation claim. 43 had received debridement (41.7%), 54 microfracture (MF) (52.4%), 3 mosaicplasty (2.9%) and 3 autologous chondrocyte implantation (ACI) (2.9%). Of the 103 claims, 36 were granted (35%). 21 following debridement (58.3%), 13 after MF (36.1%), 1 following mosaicplasty (2.8%) and 1 after ACI (2.8%). The most common reason for complaint was infection (22.1%), of which 89% were granted. The average compensation was €24.457 (range €209 – €458.943). Conclusion Compensation claims following surgical treatment of knee cartilage injuries in Scandinavia are rare. Establishing nationwide cartilage registries can add further knowledge on this troublesome disease.

Abstract
CONTEXT The prescription of opioids after elective surgical procedures has been a contributing factor to the current opioid epidemic in North America. OBJECTIVE To examine the opioid prescribing practices and rates of opioid consumption among patients undergoing common sports medicine procedures. DATA SOURCES A systematic review of the electronic databases EMBASE, MEDLINE, and PubMed was performed from database inception to December 2018. STUDY SELECTION Two investigators independently identified all studies reporting on postoperative opioid prescribing practices and consumption after arthroscopic shoulder, knee, or hip surgery. A total of 119 studies were reviewed, with 8 meeting eligibility criteria. STUDY DESIGN Systematic review. LEVEL OF EVIDENCE Level 4. DATA EXTRACTION The quantity of opioids prescribed and used were converted to milligram morphine equivalents (MMEs) for standardized reporting. The quality of each eligible study was evaluated using the Methodological Index for Non-Randomized Studies. RESULTS A total of 8 studies including 816 patients with a mean age of 43.8 years were eligible for inclusion. A mean of 610, 197, and 613 MMEs were prescribed to patients after arthroscopic procedures of the shoulder, knee, and hip, respectively. At final follow-up, 31%, 34%, and 64% of the prescribed opioids provided after shoulder, knee, and hip arthroscopy, respectively, still remained. The majority of patients (64%) were unaware of the appropriate disposal methods for surplus medication. Patients undergoing arthroscopic rotator cuff repair had the highest opioid consumption (471 MMEs), with 1 in 4 patients receiving a refill. CONCLUSION Opioids are being overprescribed for arthroscopic procedures of the shoulder, knee, and hip, with more than one-third of prescribed opioids remaining postoperatively. The majority of patients are unaware of the appropriate disposal techniques for surplus opioids. Appropriate risk stratification tools and evidence-based recommendations regarding pain management strategies after arthroscopic procedures are needed to help curb the growing opioid crisis.

Abstract
Purpose Canada has the second-highest opioid use in the world. Despite knee and shoulder arthroscopy being among the most commonly performed orthopaedic procedures, there exists little guidelines for pain management. Methods A survey was developed and distributed to members of the Arthroscopy Association of Canada. The objectives were: to understand opioid prescribing patterns after knee and shoulder arthroscopy, to determine if surgeons believe opioid over-prescription is an issue and to identify other pain management strategies surgeons are regularly using. Results A total of 38 responses were included (38.3%). Eighty-two percent of surgeons felt opioid over-prescription was an issue in arthroscopic surgery. The average post-operative knee or shoulder arthroscopy prescription included a total of 156 +/- 84.4 (0-400) mg of oral morphine equivalents (OMEs). Less than one-third of respondents (29%) had received formal peri-operative pain management training. Fifty-five percent of respondents felt that non-opioid medications do not provide adequate pain relief after arthroscopic surgery. Nearly all respondents (95%) stated they would change their prescription practice if high-quality evidence were to suggest that they should do so. Conclusions The majority of respondents identified opioid over-prescription as a problem after arthroscopic surgery. Surgeons are prescribing five times the amount of OMEs to patients that previous literature suggests the median patient uses after arthroscopic knee surgery. Surgeons generally state they would reduce or eliminate opioid prescriptions to arthroscopy patients if high-level evidence were to emerge suggesting that adequate pain control could be achieved without the use of narcotics.

Abstract
The potential use of fiber-reinforced based polycarbonate-urethanes (PCUs) as candidate meniscal substitutes was investigated in this study. Mechanical test pieces were designed and fabricated using a compression molding technique. Ultra-High Molecular Weight Polyethylene (UHMWPE) fibers were impregnated into PCU matrices, and their mechanical and microstructural properties evaluated. In particular, the tensile moduli of the PCUs were found unsuitable, since they were comparatively lower than that of the meniscus, and may not be able to replicate the inherent role of the meniscus effectively. However, the inclusion of fibers produced a substantial increment in the tensile modulus, to a value within a close range measured for meniscus tissues. Increments of up to 227% were calculated with a PCU fiber reinforcement composite. The embedded fibers in the PCU composites enhanced the fracture mechanisms by preventing the brittle failure and plastic deformation exhibited in fractured PCUs. The behavior of the composites in compression varied with respect to the PCU matrix materials. The mechanical characteristics demonstrated by the developed PCU composites suggest that fiber reinforcements have a considerable potential to duplicate the distinct and multifaceted biomechanical roles of the meniscus.

Orthop J Sports Med 2020; 8:2325967120914568. [PMID: 32313812 PMCID: PMC7153201 DOI: 10.1177/2325967120914568] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Accepted: 12/23/2019] [Indexed: 11/16/2022] Open
Abstract
Background: Radial tears of the lateral meniscus frequently accompany acute anterior cruciate ligament (ACL) injuries and lead to increased joint stress and pathological meniscal extrusion (ME). The dynamic behavior of the lateral meniscus after radial tear repair with respect to ME has not been described. Purpose: To quantitatively assess dynamic lateral ME after all-inside radial tear repair. Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent ACL reconstruction and all-inside radial tear repair of the lateral meniscus and had no history of contralateral knee injuries were included. Magnetic resonance imaging scans were acquired in loaded (50% of body weight) and unloaded conditions of both the injured and noninjured knees. A custom-made pneumatically driven knee brace was used for standardized knee positioning in 10° of flexion and with axial load application. Quantitative measures included the absolute lateral ME, meniscal body extrusion ratio, and Δ extrusion. Preoperative and postoperative unloaded extrusion data were compared by paired t tests. For postoperative data, the concomitant influence of the factors “leg” and “condition” were assessed through factorial analyses of variance. Results: A total of 10 patients with a mean follow-up of 47.9 months were enrolled. The intraclass correlation coefficient (ICC) confirmed good interrater reliability (ICC, 0.898) and excellent intrarater reliability (ICC, 0.976). In the unloaded injured leg, all-inside repair reduced ME from 3.15 ± 1.07 mm to 2.13 ± 0.61 mm (–32.4%; P = .033). Overall, load application led to a significant increase in ME (+0.34 mm [+21.8%]; P = .029). Significantly greater ME was observed in the injured knee (+1.10 mm [+93.2%]; P = .001) than in the noninjured knee. The condition × leg interaction was not significant (P = .795), suggesting that the compression-associated increase in ME did not differ significantly between the injured and noninjured knees. Conclusion: Lateral ME depends on the knee status and loading condition. All-inside repair of radial meniscal tears led to a reduction of extrusion with no alteration in dynamic lateral ME. Meniscus-preserving therapy is recommended in the case of a radial lateral meniscal tear to preserve its dynamic behavior.

Abstract
Purpose: Meniscal injury and loss of meniscus tissue lead to osteoarthritis development. Therefore, novel biologic strategies are needed to enhance meniscus tissue repair. The purpose of this study was to identify a favorable culture medium for both bone marrow-derived mesenchymal stem cells (MSCs) and meniscal tissue, and to establish a novel meniscus tissue defect model that could be utilized for in vitro screening of biologics to promote meniscus repair.Materials and Methods: In parallel, we analyzed the biochemical properties of MSC - seeded meniscus-derived matrix (MDM) scaffolds and meniscus repair model explants cultured in different combinations of serum, dexamethasone (Dex), and TGF-β. Next, we combined meniscus tissue and MSC-seeded MDM scaffolds into a novel meniscus tissue defect model to evaluate the effects of chondrogenic and meniscal media on the tissue biochemical properties and repair strength.Results: Serum-free medium containing TGF-β and Dex was the most promising formulation for experiments with MSC-seeded scaffolds, whereas serum-containing medium was the most effective for meniscus tissue composition and integrative repair. When meniscus tissue and MSC-seeded MDM scaffolds were combined into a defect model, the chondrogenic medium (serum-free with TGF-β and Dex) enhanced the production of proteoglycans and promoted integrative repair of meniscus tissue. As well, cross-linked scaffolds improved repair over the MDM slurry.Conclusions: The meniscal tissue defect model established in this paper can be used to perform in vitro screening to identify and optimize biological treatments to enhance meniscus tissue repair prior to conducting preclinical animal studies.

Timing of anterior cruciate ligament reconstruction and preoperative pain are important predictors for postoperative kinesiophobia. Knee Surg Sports Traumatol Arthrosc 2020; 28:2502-2510. [PMID: 31879792 PMCID: PMC7429522 DOI: 10.1007/s00167-019-05838-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Accepted: 12/16/2019] [Indexed: 11/10/2022]
Abstract
PURPOSE Fear of movement (kinesiophobia) is a major limiting factor in the return to pre-injury sport level after anterior cruciate ligament reconstruction (ACLR). The aim of this study was to gain insight into the prevalence of kinesiophobia pre-ACLR, 3 months post-ACLR and 12 months post-ACLR. Furthermore, the preoperative predictability of kinesiophobia at 3 months post-ACLR was addressed. METHODS A retrospective study with data, which were prospectively collected as part of standard care, was conducted to evaluate patients who underwent ACLR between January 2017 and December 2018 in an orthopaedic outpatient clinic. Patient characteristics (age, sex, body mass index), injury-to-surgery time, preoperative pain level (KOOS pain subscale) and preoperative knee function (IKDC-2000) were used as potential predictor variables for kinesiophobia (TSK-17) at 3 months post-ACLR in linear regression analysis. RESULTS The number of patients with a high level of kinesiophobia (TSK > 37) reduced from 92 patients (69.2%) preoperatively to 44 patients (43.1%) 3 months postoperatively and 36 patients (30.8%) 12 months postoperatively. The prediction model, based on a multivariable regression analysis, showed a positive correlation between four predictor variables (prolonged injury-to-surgery time, high preoperative pain level, male sex and low body mass index) and a high level of kinesiophobia at 3 months postoperatively (R2 = 0.384, p = 0.02). CONCLUSION The prevalence of kinesiophobia decreases during postoperative rehabilitation, but high kinesiophobia is still present in a large portion of the patients after ACLR. Timing of reconstruction seems to be the strongest predictor for high kinesiophobia 3 months post-ACLR. This study is the first step in the development of a screening tool to detect patients with kinesiophobia after ACLR. Identifying patients preoperatively opens the possibility to treat patients and thereby potentially increase the return to pre-injury sport level rate after ACLR. LEVEL OF EVIDENCE III.

Abstract
Meniscal injuries, particularly in the avascular zone, have a low propensity for healing and are associated with the development of osteoarthritis. Current meniscal repair techniques are limited to specific tear types and have significant risk for failure. In previous work, we demonstrated the ability of meniscus-derived matrix (MDM) scaffolds to augment the integration and repair of an in vitro meniscus defect. The objective of this study was to determine the effects of percent composition and dehydrothermal (DHT) or genipin cross-linking of MDM bioscaffolds on primary meniscus cellular responses and integrative meniscus repair. In all scaffolds, the porous microenvironment allowed for exogenous cell infiltration and proliferation, as well as endogenous meniscus cell migration. The genipin cross-linked scaffolds promoted extracellular matrix (ECM) deposition and/or retention. The shear strength of integrative meniscus repair was improved with increasing percentages of MDM and genipin cross-linking. Overall, the 16% genipin cross-linked scaffolds were most effective at enhancing integrative meniscus repair. The ability of the genipin cross-linked scaffolds to attract endogenous meniscus cells, promote glycosaminoglycan and collagen deposition, and enhance integrative meniscus repair reveals that these MDM scaffolds are promising tools to augment meniscus healing.

Abstract
BACKGROUND Hamstring autografts with a diameter of less than 8 mm for ACL reconstruction have an increased risk of failure, but there is no consensus regarding the best method to predict autograft size in ACL reconstruction. QUESTIONS/PURPOSES (1) What is the relationship between hamstring cross-section on preoperative MRI and intraoperative autograft size? (2) What is the minimum hamstring tendon cross-sectional area on MRI needed to produce an autograft of at least 8 mm at its thickest point? METHODS This was a retrospective cohort study of 68 patients. We collectively reviewed patients who underwent ACL reconstruction by three separate fellowship-trained surgeons at the Carilion Clinic between April 2010 and July 2013. We searched the patient records database of each surgeon using the keyword "ACL". A total of 293 ACL reconstructions were performed during that time period. Of those, 23% (68 patients) had their preoperative MRI (1.5 T or 3 T magnet) performed at the Carilion Clinic with MRI confirmation of acute total ACL rupture. Exclusion criteria included previous ACL reconstructions, multiligamentous injuries, and history of acute hamstring injuries.After applying the exclusion criteria, there were 29 patients in the 1.5 T magnet group and 39 in the 3 T group. Median age (range) was 29 years (12 to 50) for the 1.5 T group and 19 years (9 to 43) for the 3 T group. The patients were 41% female in the 1.5 T group and 23% female in the 3 T group. Use of 1.5 T or 3 T magnets was based on clinical availability and scheduling. The graft's preoperative cross-sectional area was compared with the intraoperative graft's diameter. The MRI measurements were performed by a single musculoskeletal radiologist at the widest point of the medial femoral condyle and at the joint line. Intraoperative measurements were performed by recording the smallest hole the graft could fit through at its widest point. Pearson's correlation coefficients were calculated to determine the relationship between graft size and tendon cross-sectional area. A simple logistic regression analysis was used to calculate the cutoff cross-sectional areas needed for a graft measuring at least 8 mm at its thickest point. Intrarater reliability was evaluated based on re-measurement of 19 tendons, which produced an overall intraclass correlation coefficient (ICC) of 0.96 95% (CI 0.93 to 0.98). A p value < 0.05 was considered significant. RESULTS In general, the correlation between MRI-measured hamstring thickness and hamstring graft thickness as measured in the operating room were good but not excellent. The three measurements that demonstrated the strongest correlation with graft size in the 1.5 T group were the semitendinosus at the medial femoral condyle (r = 0.69; p < 0.001), the semitendinosus and gracilis at the medial femoral condyle (r = 0.70; p < 0.001), and the mean semitendinosus and gracilis (r = 0.64; p < 0.001). These three measurements had correlation values of 0.53, 0.56, and 0.56, respectively, in the 3 T MRI group (all p values < 0.001). To create an 8-mm hamstring autograft, the mean semitendinosus plus gracilis cutoff values areas were 18.8 mm and 17.5 mm for the 1.5 T and 3.0 T MRI groups, respectively. CONCLUSIONS Imaging performed according to routine knee injury protocol can be used to preoperatively predict the size of hamstring autografts for ACL reconstructions. In clinical practice, this can assist orthopaedic surgeons in graft selection and surgical planning. LEVEL OF EVIDENCE Level II, diagnostic study.

Mapping the Diffusion of Technology in Orthopaedic Surgery: Understanding the Spread of Arthroscopic Rotator Cuff Repair in the United States. Clin Orthop Relat Res 2019; 477:2399-2410.

Abstract
BACKGROUND The mechanism by which surgical innovation is spread in orthopaedic surgery is not well studied. The recent widespread transition from open to arthroscopic rotator cuff repair techniques provides us with the opportunity to study the spread of new technology; doing so would be important because it is unclear how novel orthopaedic techniques disseminate across time and geography, and previous studies of innovation in healthcare may not apply to the orthopaedic community. QUESTIONS/PURPOSES (1) How much regional variation was associated with the adoption of arthroscopic rotator cuff repair in the United States Medicare population between 2006 and 2014 and how did this change over time? (2) In which regions of the United States was arthroscopic rotator cuff repair first adopted and how did it spread geographically? (3) Which regional factors were associated with the adoption of this new technology? METHODS We divided the United States into 306 hospital referral regions based upon referral patterns observed in the Centers for Medicare & Medicaid Services MedPAR database, which records all Medicare hospital admissions; this has been done in numerous previous studies using methodology introduced by the Dartmouth Atlas. The proportion of arthroscopic rotator cuff repairs versus open rotator cuff repairs in each hospital referral region was calculated using adjusted procedural rates from the Medicare Part B Carrier File from 2006 to 2014, as it provided a nationwide sample of patients, and was used as a measure of adoption. A population-weighted, multivariable linear regression analysis was used to identify regional characteristics independently associated with adoption. RESULTS There was substantial regional variation associated with the adoption of arthroscopy for rotator cuff repair as the percentage of rotator cuff repair completed arthroscopically in 2006 ranged widely among hospital referral regions with a high of 85.3% in Provo, UT, USA, and a low of 16.7% in Seattle, WA, USA (OR 30, 95% CI 17.6 to 52.2; p < 0.001). In 2006, regions in the top quartiles for Medicare spending (+9.1%; p = 0.008) independently had higher adoption rates than those in the bottom quartile, as did regions with a greater proportion of college-educated residents (+12.0%; p = 0.009). The Northwest region (-14.4%; p = 0.009) and the presence of an academic medical center (-5.8%; p = 0.026) independently had lower adoption than other regions and those without academic medical centers. In 2014, regions in the top quartiles for Medicare spending (+5.7%; p = 0.033) and regions with a greater proportion of college-educated residents (+9.4%; p = 0.005) independently had higher adoption rates than those in the bottom quartiles, while the Northwest (-9.6%; p = 0.009) and Midwest regions (-5.1%; p = 0.017) independently had lower adoption than other regions. CONCLUSION The heterogeneous diffusion of arthroscopic rotator cuff repair across the United States highlights that Medicare beneficiaries across regions did not have equal access to these procedures and that these discrepancies continued to persist over time. A higher level of education and increased healthcare spending were both associated with greater adoption in a region and conversely suggest that regions with lower education and healthcare spending may pursue innovation more slowly. There was evidence that regions with academic medical centers adopted this technology more slowly and may highlight the role that private industry and physicians in nonacademic organizations play in surgical innovation. Future studies are needed to understand if this later adoption leads to inequalities in the quality and value of surgical care delivered to patients in these regions.

Abstract
BACKGROUND Meniscus surgeries are frequently performed in orthopaedics. However, their current status is not well known in many countries, including Korea. This study aimed to investigate the national trends of meniscus surgery in Korea. METHODS Information from the national database was acquired through the Korean Health Insurance Review and Assessment Service from 2010 to 2017. All cases coded as meniscectomy or meniscus repair were included. The total number and incidence of cases of meniscus surgery per 100,000 persons were determined, and the results were stratified by age and gender. The meniscus repair ratio for the total number of meniscus surgeries was evaluated. RESULTS The total number and incidence of meniscectomy cases were 65,752 and 137, respectively, in 2010, which increased to 74,088 and 154, respectively, in 2017. The number of meniscectomies increased by 12.67% in 8 years. The total number and incidence of meniscus repair cases were 9,055 and 18, respectively, in 2010, which increased to 14,947 and 31 in 2017. The number of meniscus repairs increased by 65.04%. The meniscus repair ratio was 12.1% in 2010, which increased to 16.8% in 2017. The highest peak was noted for patients who underwent meniscus surgeries in their 50s and 60s. Meniscectomy was performed more frequently in women (57%) than in men (43%), whereas repair was performed more frequently in men (54%) than in women (46%) over the study period. CONCLUSION The total number and incidence of meniscus surgeries increased from 2010 to 2017; the number and incidence of meniscus repair procedures increased more rapidly than those of meniscectomy, with the peak treatment age for both surgeries being in the 50s and 60s. The current study will contribute to understanding the epidemiology of meniscus surgery, its prevention, and cost-saving measures in Korea.

Abstract
Electrospinning is an attractive method of fabricating nanofibers that replicate the ultrastructure of the human meniscus. However, it is challenging to approximate the mechanical properties of meniscal tissue while maintaining the biocompatibility of collagen fibers. Our objective was to determine if functionalizing polylactic acid (PLA) nanofibers with collagen would enhance their biocompatibility. We therefore used coaxial electrospinning to generate core-shell nanofibers with a core of PLA for mechanical strength and a shell of collagen to enhance cell attachment and matrix synthesis. We characterized the nanostructure of the engineered scaffolds and measured the hydrophilic and mechanical properties. We assessed the performance of human meniscal cells seeded on coaxial electrospun scaffolds to produce meniscal tissue by gene expression and histology. Finally, we investigated whether these cell-seeded scaffolds could repair surgical tears created ex vivo in avascular meniscal explants. Histology, immunohistochemistry, and mechanical testing of ex vivo repair provided evidence of neotissue that was significantly better integrated with the native tissue than with the acellular coaxial electrospun scaffolds. Human meniscal cell-seeded coaxial electrospun scaffolds may have potential in enhancing repair of avascular meniscus tears. Impact Statement The success of any tissue-engineered meniscus graft relies on its ability to mimic native three-dimensional microstructure, support cell growth, produce tissue-specific matrix, and enhance graft integration into the repair site. Polylactic acid scaffolds possess the desired mechanical properties, whereas collagen scaffolds induce better cell attachment and enhanced tissue regeneration. We therefore fabricated nanofibrous scaffolds that combined the properties of two biomaterials. These novel coaxial scaffolds more closely emulated the structure, mechanical properties, and biochemical composition of native meniscal tissue. Our findings of meniscogenic tissue generation and integration in meniscus defects have the potential to be translated to clinical use.

Abstract
Diseases that jeopardize the musculoskeletal system and cause chronic impairment are prevalent throughout the Western world. In Germany alone, ~1.8 million patients suffer from these diseases annually, and medical expenses have been reported to reach 34.2bn Euros. Although musculoskeletal disorders are seldom fatal, they compromise quality of life and diminish functional capacity. For example, musculoskeletal disorders incur an annual loss of over 0.8 million workforce years to the German economy. Among these diseases, traumatic skeletal muscle injuries are especially problematic because they can occur owing to a variety of causes and are very challenging to treat. In contrast to chronic muscle diseases such as dystrophy, sarcopenia, or cachexia, traumatic muscle injuries inflict damage to localized muscle groups. Although minor muscle trauma heals without severe consequences, no reliable clinical strategy exists to prevent excessive fibrosis or fatty degeneration, both of which occur after severe traumatic injury and contribute to muscle degeneration and dysfunction. Of the many proposed strategies, cell-based approaches have shown the most promising results in numerous pre-clinical studies and have demonstrated success in the handful of clinical trials performed so far. A number of myogenic and non-myogenic cell types benefit muscle healing, either by directly participating in new tissue formation or by stimulating the endogenous processes of muscle repair. These cell types operate via distinct modes of action, and they demonstrate varying levels of feasibility for muscle regeneration depending, to an extent, on the muscle injury model used. While in some models the injury naturally resolves over time, other models have been developed to recapitulate the peculiarities of real-life injuries and therefore mimic the structural and functional impairment observed in humans. Existing limitations of cell therapy approaches include issues related to autologous harvesting, expansion and sorting protocols, optimal dosage, and viability after transplantation. Several clinical trials have been performed to treat skeletal muscle injuries using myogenic progenitor cells or multipotent stromal cells, with promising outcomes. Recent improvements in our understanding of cell behaviour and the mechanistic basis for their modes of action have led to a new paradigm in cell therapies where physical, chemical, and signalling cues presented through biomaterials can instruct cells and enhance their regenerative capacity. Altogether, these studies and experiences provide a positive outlook on future opportunities towards innovative cell-based solutions for treating traumatic muscle injuries-a so far unmet clinical need.

Abstract
Shoulder arthroscopy is the second most common orthopaedic procedure. Diagnostic arthroscopy of the shoulder requires an efficient and reproducible technique. In this Technical Note, we describe a step-wise approach to diagnostic arthroscopy of the shoulder. This technique is performed using a posterior viewing portal. It can be performed from the beach chair or the lateral decubitus position. This technique uses a 2-circle approach: the surgeon first evaluates the glenoid aspect of the joint space, followed by the humeral aspect of the joint space. This method ensures a complete and consistent evaluation of the glenohumeral joint.

Abstract
IMPACT STATEMENT The only FDA-approved partial meniscus scaffold, the Collagen Meniscus Implant (CMI), is not approved for reimbursement by government and only reimbursable by certain private insurers. Scaffolds with improved mechanical properties and greater efficacy are needed. A previous study (Ghodbane, et al. DOI: 10.1002/jbm.b.34331) demonstrated the ability of our novel acellular, off-the shelf scaffold to restore knee biomechanics following partial meniscectomy, which could potentially decrease the risk of osteoarthritis following partial meniscectomy, providing the motivation for this study. This article presents a first-in-animal feasibility study.

Abstract
Background Shoulder arthroscopy is a commonly performed, critical component of orthopaedic residency training. However, it is unclear whether there are additional risks to patients in cases associated with resident involvement. Purpose To compare shoulder arthroscopy cases with and without resident involvement via a large, prospectively maintained national surgical registry to characterize perioperative risks. Study Design Cohort study; Level of evidence, 3. Methods The prospectively maintained American College of Surgeons National Surgical Quality Improvement Program registry was queried to identify patients who underwent 1 of 12 shoulder arthroscopy procedures from 2005 through 2012. Multivariate Poisson regression with robust error variance was used to compare the rates of postoperative adverse events and readmission within 30 days between cases with and without resident involvement. Multivariate linear regression was used to compare operative time between cohorts. Results A total of 15,774 patients with shoulder arthroscopy were included in the study, and 12.3% of these had a resident involved with the case. The overall rate of adverse events was 1.09%. On multivariate analysis, resident involvement was not associated with increased rates of any aggregate or individual adverse event. There was also no association between resident involvement and risk of readmission within 30 days. Resident involvement was not associated with any difference in operative time (P = .219). Conclusion Resident involvement in shoulder arthroscopy was not associated with increased risk of adverse events, increased operative time, or readmission within 30 days. The results of this study suggest that resident involvement in shoulder arthroscopy cases is a safe method for trainees to learn these procedures.

Abstract
Introduction: Shoulder arthroscopies are among the most frequently performed surgeries by orthopaedic surgeons. Little is known about complication rates among recently trained surgeons. The purpose of this study was to examine the type and frequency of complications of common arthroscopic shoulder procedures performed by candidates challenging the American Board of Orthopaedic Surgery: Part II, certification examination. Methods: Data were obtained from the American Board of Orthopaedic Surgery database for orthopaedic surgeons who sat for the part II examination from 2012 to 2016. In total, 27,072 procedures were reviewed. The database was queried to determine the type and frequency of complications for patients who underwent shoulder arthroscopy, including arthroscopic rotator cuff repair, labrum repair, biceps tenodesis, and bony/soft tissue débridement procedures. Complications were classified as surgical, anesthetic, or medical. Factors affecting complication rates were investigated including surgeon's fellowship training, geographic location, and patients’ age and sex. Results: Patients with surgical complications (n = 2,133; 7.9%) were more common than anesthetic (n = 263; 1.0%) or medical (n = 607; 2.2%) complications. There was a significant variation in the surgical complication rate among different arthroscopic shoulder procedures, ranging from 5.4% for labral repair to 10.3% for rotator cuff repair and biceps tenodesis. Stiffness/arthrofibrosis was the most commonly recorded surgical complication (2.2%). Surgical complication rates were lowest in the Northeast region (6.7%; P < 0.01) and in patients younger than 21 years (3.8%; P < 0.01). Women had significantly higher rate of complications than men (8.4% versus 7.6%; P = 0.02). Among anesthetic-related complications, 61.6% were related to regional nerve blocks. The overall revision surgery and readmission rates were 0.8% and 1.0%, respectively. Conclusion: The overall self-reported surgical complication rate for arthroscopic shoulder procedures was 7.9%, which is higher than the rates reported in the literature. Although the rate of anesthetic complications is low (1.0%), adverse events related to nerve blocks made up most of the overall anesthetic related complications.

Abstract
INTRODUCTION Anterior cruciate ligament tears are a common ligamentous knee injury and are usually managed with arthroscopic reconstruction surgery using a tourniquet. The employment of a tourniquet in the management of an anterior cruciate ligament tear has been a debatable topic for some time. Here, we discuss our technique in the reconstruction of anterior cruciate ligament tears without the use of a tourniquet. MATERIALS AND METHODS We performed 26 anterior cruciate ligament reconstruction surgeries using hamstring grafts without the use of a tourniquet. The outcomes measured were pain using the visual analogue scale, knee swelling, range of movement and bleeding. RESULTS Using this technique, we have noted considerable reduction in knee swelling and pain. In addition, there was considerable improvement in the range of movement postoperatively, and there were no bleeding complications noted. CONCLUSIONS We consider ACL reconstruction without a tourniquet to be an excellent alternative to conventional reconstruction with the use of tourniquet.

Abstract
BACKGROUND Virtual reality arthroscopic simulators are an attractive option for resident training and are increasingly used across training programs. However, no study has analyzed the utility of simulators for trainees based on their level of training/postgraduate year (PGY). PURPOSE/HYPOTHESIS The primary aim of this study was to determine the utility of the ArthroS arthroscopic simulator for orthopaedic trainees based on their level of training. We hypothesized that residents at all levels would show similar improvements in performance after completion of the training modules. STUDY DESIGN Descriptive laboratory study. METHODS Eighteen orthopaedic surgery residents performed diagnostic knee and shoulder tasks on the ArthroS simulator. Participants completed a series of training modules and then repeated the diagnostic tasks. Correlation coefficients (r 2) were calculated for improvements in the mean composite score (based on the Imperial Global Arthroscopy Rating Scale [IGARS]) as a function of PGY. RESULTS The mean improvement in the composite score for participants as a whole was 11.2 ± 10.0 points (P = .0003) for the knee simulator and 14.9 ± 10.9 points (P = .0352) for the shoulder simulator. When broken down by PGY, all groups showed improvement, with greater improvements seen for junior-level residents in the knee simulator and greater improvements seen for senior-level residents in the shoulder simulator. Analysis of variance for the score improvement variable among the different PGY groups yielded an f value of 1.640 (P = .2258) for the knee simulator data and an f value of 0.2292 (P = .917) for the shoulder simulator data. The correlation coefficient (r 2) was -0.866 for the knee score improvement and 0.887 for the shoulder score improvement. CONCLUSION Residents training on a virtual arthroscopic simulator made significant improvements in both knee and shoulder arthroscopic surgery skills. CLINICAL RELEVANCE The current study adds to mounting evidence supporting virtual arthroscopic simulator-based training for orthopaedic residents. Most significantly, this study also provides a baseline for evidence-based targeted use of arthroscopic simulators based on resident training level.

Abstract
BACKGROUND Partial meniscectomy is one of the most commonly performed orthopaedic procedures for a meniscus tear. Decreased contact area and increased contact pressure have been seen in partial meniscectomies from treatment of various types of meniscal tears; however, the biomechanical effect of a horizontal cleavage tear in the lateral meniscus and subsequent treatment are unknown. QUESTIONS/PURPOSES This study asked whether a horizontal cleavage tear of the lateral meniscus, resecting the inferior leaf, and further resecting the superior leaf would (1) decrease contact area and (2) increase peak contact pressure. METHODS Eleven fresh-frozen human cadaveric knees were evaluated under five conditions of intact meniscus, horizontal cleavage tear, inferior leaf resection, and resection of the inferior and superior leaves of the lateral meniscus. Tibiofemoral contact area and pressure were measured at 0° and 60° knee flexion under an 800-N load, normalized to that at the intact condition of the corresponding knee flexion, and compared across the five previously described conditions. RESULTS At 0° knee flexion, normalized contact area with inferior leaf resection (65.4% ± 14.1%) was smaller than that at the intact condition (100% ± 0.0%, p < 0.001); smaller than horizontal cleavage tear (94.1% ± 5.8%, p = 0.001) contact area; and smaller than repaired horizontal tear (92.8% ± 8.2%, p = 0.001) contact area. Normalized contact area with further superior leaf resection (50.5% ± 7.3%) was smaller than that at the intact condition (100% ± 0.0%, p < 0.001); smaller than horizontal cleavage tear (94.1% ± 5.8%, p < 0.001) contact area; and smaller than repaired horizontal tear (92.8% ± 8.2%, p < 0.001) contact area. At 60° flexion, normalized contact area with inferior leaf resection (76.1% ± 14.8%) was smaller than that at the intact condition (100% ± 0.0%, p = 0.004); smaller than horizontal cleavage tear (101.8% ± 7.2%, p = 0.006) contact area; and smaller than repaired horizontal tear (104.0% ± 13.3%, p < 0.001) contact area. Normalized contact area with further superior leaf resection (52.1% ± 16.7%) was smaller than that at the intact condition (100% ± 0.0%, p < 0.001); smaller than horizontal cleavage tear (101.8% ± 7.2%, p < 0.001) contact area; and smaller than repaired horizontal tear (104.0% ± 13.3%, p < 0.001) contact area. At 60° flexion, contact area with both leaf resection (52.1% ± 16.7%) was smaller than that with inferior leaf resection (76.1% ± 14.8%, p = 0.039). At 0° knee flexion, peak pressure increased to 127.0% ± 22.1% with inferior leaf resection (p = 0.026) and to 138.6% ± 24.3% with further superior leaf resection (p = 0.002) compared with that at the intact condition (100% ± 0.0%). At 60° flexion, compared with that at the intact condition (100% ± 0.0%), peak pressure increased to 139% ± 33.6% with inferior leaf resection (p = 0.035) and to 155.5% ± 34.7% (p = 0.004) with further superior leaf resection. CONCLUSIONS Resection of the inferior leaf or both leaves of the lateral meniscus after a horizontal cleavage tear resulted in decreased contact area and increased peak contact pressure at 0° and 60° knee flexion. CLINICAL RELEVANCE In vitro resection of one or both leaves of a horizontal cleavage tear of the lateral meniscus causes increases in peak pressure, consistent with other types of partial meniscectomies associated in a clinical setting with excessive loading and damage to knee cartilage. Clinical outcomes in patients undergoing partial leaf meniscectomy could confirm this theory. Avoidance of resection may be relatively beneficial for long-term function. The findings of this in vitro study lend biomechanical support for nonoperative management.

Abstract
Anterior cruciate ligament (ACL) reconstruction is one of the most common procedures studied in the orthopaedic literature. In this regard, graft preparation is a key factor for successful outcomes. Although current methods to reconstruct the ACL are generally perceived to be successful, recent studies indicate that normal structure and function of the knee are fully restored in less than half of the patients. Therefore, biologically augmenting these scaffolds could provide a potential solution for improving healing times and biomechanical properties of the graft. The purpose of this Technical Note is to describe our preferred technique for an ACL graft preparation (quadriceps tendon) augmented with platelet-rich plasma.

Abstract
Background The importance of meniscus preservation is widely recognized. There have been a few studies describing trends in meniscectomy and meniscus repair in the United States; however, they presented differing results. We reported annual trends in meniscus surgery, using a national database in Japan. Methods We interrogated the Diagnosis Procedure Combination database, which represents approximately half of all hospital admissions in Japan. We included the patients who underwent meniscectomy and meniscus repair between July 2007 and March 2015. The diagnosis, age and sex of each patient were recorded. Results We identified 83,105 patients: 69,310 underwent meniscectomy; 13,416 underwent meniscus repair and 379 underwent both in a single admission. The proportion of patients undergoing meniscus repair rose from 7.0% in 2007 to 25.9% in 2014 (p < 0.001), while the proportion undergoing meniscectomy fell from 92.8% in 2007 to 73.3% in 2014 (p < 0.001). Among patients under 30 years old, the proportions undergoing meniscus repair or meniscectomy in 2014 were 50.3% versus 48.3%, respectively. A bimodal age distribution was observed for meniscectomy, with peaks at 10–19 years of age and 60–69 years of age, whereas most patients undergoing meniscus repair were 10–19 years of age. Conclusions We found characteristic trends where the popularity of meniscus repair increased rapidly at the expense of meniscectomy in Japan during the study period. In the last survey year, the proportion of meniscus repair exceeded that of meniscectomy in those younger than 30 years. Meniscectomy was undertaken most often in adolescents and early old age, while meniscus repair was undertaken most often in adolescents.

Abstract
Soft tissue trauma of skeletal muscle is one of the most common side effects in surgery. Muscle injuries are not only caused by accident-related injuries but can also be of an iatrogenic nature as they occur during surgical interventions when the anatomical region of interest is exposed. If the extent of trauma surpasses the intrinsic regenerative capacities, signs of fatty degeneration and formation of fibrotic scar tissue can occur, and, consequentially, muscle function deteriorates or is diminished. Despite research efforts to investigate the physiological healing cascade following trauma, our understanding of the early onset of healing and how it potentially determines success or failure is still only fragmentary. This review focuses on the initial physiological pathways following skeletal muscle trauma in comparison to bone and tendon trauma and what conclusions can be drawn from new scientific insights for the development of novel therapeutic strategies. Strategies to support regeneration of muscle tissue after injury are scarce, even though muscle trauma has a high incidence. Based on tissue specific differences, possible clinical treatment options such as local immune-modulatory and cell therapeutic approaches are suggested that aim to support the endogenous regenerative potential of injured muscle tissues.

Abstract
Background: Patient-reported outcome (PRO) surveys have become increasingly important in both improving patient care and assessing outcomes. Purpose/Hypothesis: The purpose of this study was to evaluate which variables are associated with compliance with completing PRO surveys in patients who have undergone anterior cruciate ligament reconstruction (ACLR). The authors hypothesized that older patient age and longer time since ACLR would be associated with lower completion rates of PRO surveys preoperatively and at postoperative time points. Study Design: Case series; Level of evidence, 4. Methods: All patients who underwent ACLR by a sports medicine fellowship–trained orthopaedic surgeon at a single institution and were electronically assigned PRO surveys through a data collection system preoperatively between December 2013 and March 2015 were included. Postoperatively, PRO surveys were sent to patients’ email addresses at 6, 12, and 24 months. Demographics, history, and operative and postoperative information were evaluated for an association with survey completion rates. Results: A total of 256 patients met the inclusion criteria. There were 140 (54.7%) male and 116 (45.3%) female patients, with an overall mean age of 28.6 ± 11.9 years. Only 19 (7.4%) patients completed all preoperative and postoperative surveys at all time points. Less than half of the patients (n = 104; 40.6%) completed both the preoperative survey and at least 1 postoperative survey. There was a steady decrease in the completion rate of PRO surveys postoperatively over time (Pearson r = –0.995, P = .005). Male patients had significantly worse compliance with completing PRO surveys preoperatively and at a minimum of 1 time point postoperatively (P = .044). Patients who did not identify as athletes or report frequent exercise (≥3 times/wk) had significantly worse compliance with completing any PRO surveys (P = .046). Lower body mass index was associated with greater odds of compliance with completing the preoperative survey and 24-month postoperative survey (odds ratio, 0.902; P = .029). Conclusion: An inverse relationship was found between the surgery-to-survey period and percentage of those completing PRO surveys, with poor overall compliance. Male sex and not self-identifying as an athlete or performing frequent physical exercise were associated with lower completion rates of PRO surveys, while lower body mass index was associated with a greater rate of completion.
