Cementless versus cemented unicompartmental knee arthroplasty: a systematic review of comparative studies. Musculoskelet Surg 2023; 107:255-267. [PMID: 36689086 DOI: 10.1007/s12306-023-00773-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 01/08/2023] [Indexed: 01/24/2023]
Abstract
There are still some controversies regarding the clinical use of cementless UKAs. The aim of this systematic review was to determine whether cementless medial UKA leads to similar outcomes compared to cemented medial UKA. This search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews guidelines (PRISMA). The random effects model with 95% confidence interval (CI) was applied to the analysis. The I2 statistic was used to assess study heterogeneity. Six studies were eligible for inclusion (4784 UKAs, 4776 patients): 2947 cemented UKAs (61.6%) and 1837 cementless UKAs (38.4%). The overall mean follow-up was 4.9 years. The all-cause reoperation rate was 11.3% (80 of 706) at mean 5.7-year follow-up for cemented UKA and 6.9% (57 of 824) at mean 4.1-year follow-up for the cementless. The overall revision rate was 10.2% (303 of 2947) for the cemented and 5.8% (108 of 1837) for the cementless. Aseptic loosening was the most frequent reason of revision (2.3% cemented vs 0.5% cementless). The overall rate of radiolucent lines (RLL) was 28.3% (63 of 223) in the cemented cohort and 11.1% in the cementless (26 of 234). All the studies reported improved functional outcomes. Cementless UKA provides at least equivalent if not better results compared to cemented UKA. Despite the use of cemented UKA outnumber cementless fixation, available data shows that cementless UKA had a reduced midterm revision rate, while providing similar functional outcomes.

Abstract
Lymphocyte transformation testing (LTT) is often used in the workup for possible metal allergy after total knee arthroplasty (TKA) but the correlation of this test with other diagnostic metal-allergy findings in patients undergoing revision TKA for suspected metal allergy has not been established. A single-center, single-surgeon cohort of 19 TKAs in which both components were revised for presumed implant-related metal allergy based on history, physical, and LTT testing, to nonnickel-containing implants were retrospectively identified. Histopathologic samples obtained intraoperatively were semiquantitatively analyzed using both the Hospital for Special Surgery (HSS) synovial pathology score and the Campbell aseptic lymphocyte-dominant vasculitis-associated lesion (ALVAL) score. As histopathology control group, we included in the study an additional cohort of 17 patients who received aseptic revision TKA and had no history of reported or tested metal sensitivity. All preoperative LTT results were highly reactive to nickel. However, this did not correlate with local periarticular tissue response in 18 of 19 cases which demonstrated a low HSS synovial score (mean: 3.8 ± 2.8, of a maximum score of 28) and the low Campbell ALVAL scores (mean: 2.5/10 ± 1.3, of a maximum score of 10). There were not any significant differences between the study group (suspected implant-related metal allergy) and the control group (nonsuspected implant-related metal allergy) in regard to (1) the Campbell score and (2) the HSS synovial inflammatory score. Knee Society Clinical Rating System (KSCRS) function score improved significantly after revision (mean postoperative increase: 34.0 ± 17. 2; p < 0.001), as well as mean visual analog scale (VAS) pain (mean postoperative decrease: 33.3 ± 26.4; p < 0.01) score. The short-term survival rate (at mean follow-up of 26.1 months) of this patient cohort was 100%. In this cohort of revised TKA patients with suspected nickel allergy based on clinical presentation and LTT positive results, intraoperative histopathology was essentially normal. However, all patients with suspected nickel allergy showed a significant clinical and functional improvement with excellent short-term survival rates. The clinical significance of a positive LTT needs further study.

Abstract
PURPOSE Since its introduction in 1988, the double-tapered polished Exeter cemented stem has been widely adopted in primary total hip arthroplasty (THA). Despite the results coming from the arthroplasty registries have proven great survivorship, the aim of this study was to dig deeper and describe the modes of failure of the Exeter stem at 15 years follow-up while reporting the clinical and radiographic outcomes. METHODS A search of PubMed, MEDLINE, and Embase was performed using the Preferred Reporting Items for Systematic Review and Meta-Analyses since inception of database to January 2022. A meta-analysis was performed on stem's failure rates and clinical outcomes using random effects models. Publication bias was assessed with funnel plots. RESULTS Overall, ten studies met the inclusion criteria with 2167 hips at mean 14.8 ± 4.1 years follow-up. The meta-effect estimate for revision rate for stem-related reasons was 3.8% (CI 95% 2.1-5.6, p < 0.01). The meta-effect for revision rate for stem aseptic loosening (AL) was 0.22% (CI 95% 0-0.4, p = 0.048) and for periprosthetic fracture was 0.6% (CI95% 0.3-0.9, p < 0.001). The meta effect estimate for Oxford Hip Score (OHS) at final follow-up was 32.4 (moderate; CI 95% 23.2-41.6, p <0.001) with and heterogeneity among the studies of I2 0%. Radiolucent lines were reported in 5.5% of cases, with 1.0% of cases (21 hips) reported to be progressive. CONCLUSION Current evidence suggests that the Exeter cemented stem not only has proven long-term outstanding reliability with a revision rate of 3.8%, but also incredibly low revision rates for AL (0.22%) and periprosthetic fracture (0.6%). It is suitable for a variety of indications, and the consistent radiological appearances indicate durable fixation and load transmission while being associated with a remarkably low stem-related complication rate.

Abstract
Concerns persist that the Optetrak Logic posterior-stabilized (PS) total knee arthroplasty (TKA) femoral component might correlate with early failures due to aseptic loosening. The primary aim of this study was to examine if the use of the Optetrak Logic PS femoral component is associated with early (<5 years) and more extensive aseptic loosening compared with other PS femoral components. This is a single-institution retrieval analysis and revision registry study (based on prospectively collected data) of 27 failed primary PS TKA patients with loose femoral components that underwent revision TKAs between 2016 and 2019. Patients were stratified by components type: Group A (n = 16) received the Optetrak Logic PS femoral component, while Group B (n = 11) received other PS femoral components. Burnishing (macroscopic polishing of the component's backside) was observed and graded as a marker for relative motion at the cement-implant interface. No significant differences were found between the two groups regarding the baseline demographic, radiographic, and clinical characteristics. Mean length of implantation for Group A (3.8 ± 2.9 years) was significantly shorter (p < 0.001) than that of Group B (12.0 ± 6.7 years). A significant difference (p = 0.009) was found in presence of backside femoral burnishing between Group A (15 of 16 patients; 93.8%) and group B (5 of 11 patients; 45.6%). Furthermore, we found a significant difference (p < 0.001) in the severity of burnishing between Group A (13 of 16 patients with severe degree of burnishing; 81.3%) and Group B (1 of 11 patients with severe degree of burnishing; 9.1%). In contrast to Group B, a distinctive macroscopic pattern found in Logic retrieved femoral components (Group A) was the total absence of cement in the backside surface. The use of the Optetrak Logic PS TKA femoral component was associated with early aseptic loosening and increased presence and severity of backside burnishing with early cement-implant interface debonding compared with other commercially available types of PS TKA femoral components. The earlier failure rate with this implant is of concern.

Abstract
BACKGROUND A number of papers have been published about the clinical performance of modern rough-blasted titanium Burch-Schneider antiprotrusio cages (BS-APCs) for the treatment of acetabular bone defects. However, no systematic review of the literature has been published to date. METHODS The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews were queried for publications using keywords pertinent to Burch-Schneider antiprotrusio cage, revision THA, and clinical outcomes. RESULTS 8 articles were found to be suitable for inclusion in the present study in which 374 cases (370 patients) had been treated with modern BS-APCs. Most acetabular bone defects were type 3 according to the Paprosky classification (type 2C: 18.1%, 3A: 51%, and 3B: 28.9%). The overall re-revision rate for the 374 acetabular reconstructions with modern BS-APCs was 11.5% (43 cases). The short-term survival rate of the modern BS-APC construct was 90.6% (339 out of 374 cases), while the mid-term survival rate was 85.6% (320 out of 374 cases), and the long-term survival rate 62% (54 out of 87 cases). The most common reasons for revision were aseptic loosening (5.6%), periprosthetic joint infection (3.8%), dislocation (2.7%), and acetabular periprosthetic fracture (1.9%). CONCLUSIONS There was moderate quality evidence to show that the use of modern rough blasted titanium BS-APCs in cases of acetabular bone loss has an unacceptably high failure rate (38%). Given that antiprotrusio cages do not provide any biological fixation, we would not recommend the routine use of modern BS-APCs in complex revision THA cases. By contrast, the satisfactory short- to mid-term outcome of modern BS-APCs in combination with their low cost compared to highly porous acetabular implants, make us feel that BS-APCs might still be used in selected elderly or low-demand patients without severe superomedial acetabular bone loss.

Highly cross-linked polyethylene in primary total knee arthroplasty is associated with a lower rate of revision for aseptic loosening: a meta-analysis of 962,467 cases. Arch Orthop Trauma Surg 2022; 142:1177-1184. [PMID: 33847797 DOI: 10.1007/s00402-021-03887-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 03/27/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND The evolution in total knee arthroplasty (TKA) includes the highly cross-linked polyethylene (HXLPE) which has been reported as an effective manner to reduce the wear of the polyethylene and the osteolysis. The purpose of the present study is to synthesize the results of comparative studies between HXLPE and conventional polyethylenes and determine their effect in primary TKA. METHODS The US National Library of Medicine (PubMed/MEDLINE) and the Cochrane Database of Systematic Reviews were queried for publications utilizing the following keywords: "cross-linked", "polyethylene", "HXLPE", "conventional", "total knee arthroplasty", "TKA", "total knee replacement" and "TKR" combined with Boolean operators AND and OR. RESULTS Ten studies met the inclusion criteria and were included in the present meta-analysis with 962,467 patients. No significant difference was found regarding the revision rate for any reason between the patients who received HXLPE and those with conventional liner (OR 0.67; 95% CI 0.39-1.18; I2: 97.7%). In addition, there was no difference regarding the radiolucent lines between the two types of liners (OR 0.54; 95% CI 0.20-1.49; I2: 69.4%). However, with data coming from seven studies enrolling a total of 411,543 patients, it was demonstrated that patients who received HXLPE were less likely to be revised due to aseptic loosening compared to the patients with conventional liners (OR 0.35; 95% CI 0.31-0.39; I2: 0.0%). CONCLUSION The present meta-analysis showed that regarding the overall revision rate and radiographic outcomes there was no significant difference between the two types of liners. On the other hand, the significantly less revision rate due to loosening supports the routine continued use of HXLPE in primary TKA.

Abstract
PURPOSE To assess the MRI-measured structural integrity of hamstring autograft at 9 months after anterior cruciate ligament reconstruction (ACLR) surgery. METHODS A prospective cohort study was conducted including 34 patients (mean age 36.8 ± 11.8 years; 73.5% males) who underwent ACLR with hamstring autograft. In addition, 36 patients (mean age 39.2 ± 10.5 years; 69.4% males) without any ACL injury were also reviewed and served as control group. The primary outcome used for examining graft maturity at 9 months after ACLR was the MRI-based signal-to-noise quotient (SNQ) of reconstructed ACL. SNQ values were stratified into 3 different categories: excellent: < 0.1; good: ≥ 0.1 and ≤ 0.19; fair: ≥ 0.2. The KT-1000 knee arthrometer was used to measure the side-to-side difference in the anterior tibial translation between the ACLR knee and the contralateral healthy knee in the ACLR group. RESULTS Reconstructed ACLs were found with a mean SNQ of 0.078 ± 0.061, while almost all ACL-reconstructed patients (97%; 33 out of 34) were found with excellent or good SNQ values (< 0.019). The mean KT-1000 in the ACLR group was 0.071 mm ± 0.926 mm, while there were no patients in the ACLR cohort with a KT-1000 value > 3 mm. The mean 9-months MRI-based SNQ of ACLR group was significantly higher compared to the mean MRI-based SNQ of the control group (p < 0.001). Multiple regression analysis showed no correlation between SNQ and age, gender, time from injury to ACLR, graft size, or simultaneous treatment of additional intra-articular knee lesions. CONCLUSIONS In this cohort of 34 ACL-reconstructed patients, 97% of hamstring tendon autografts demonstrated excellent/good MRI signal intensity and excellent functional results (KT-1000 < 3 mm) at 9 months after surgery. Based on this finding, it is suggested that return to sports after ACLR with hamstring autograft can be considered safe at 9 months post surgery. Furthermore, while structural integrity of the graft has been achieved at this time point, statistical differences found in SNQ values of ACL-reconstructed patients compared to ACLs of healthy individuals highlight the continuing process of graft maturation and remodelling. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Plantar fasciitis is a common cause of musculoskeletal discomfort. Minimally invasive interventions are preferred as second-line treatments following failure of conservative management. We report on a novel technique of ultrasound-guided percutaneous release of the medial third of the plantar fascia with the use of a fine cutting device for the treatment of persistent plantar fasciitis. METHODS This is a retrospective case series of all patients treated with the technique between 2013 and 2015. Patients had failed conservative management for a minimum of 6 months. The procedure was performed in an outpatient setting under local anesthesia. Under continuous ultrasound guidance, release of the medial third of the plantar fascia from the calcaneus was performed using an ophthalmic V-Lance knife through a medial stab wound entry point. RESULTS Fifteen patients (six men and nine women) with an average age of 54.7 years were included. The mean (standard deviation [SD]) visual analogue scale score for pain improved significantly, from 66.0 (SD, 18.8) preoperatively to each consecutive follow-up point: 29.3 (SD, 25.2) at 2 weeks, 30.0 (SD, 27.8) at 4 weeks, and 34.0 (SD, 26.1) at 12 weeks (P < .001). The mild increase in visual analogue scale score between 4 and 12 weeks was statistically significant (P = .018). Average duration of required analgesia was 5.5 days and average time required to return to usual activities was 5.7 days. Two patients suffered with refractory neuropathic pain over the lateral border of the foot without any obvious abnormality. CONCLUSIONS Ultrasound-guided percutaneous release with the use of a fine cutting device could be an alternative option for the treatment of persistent plantar fasciitis. The technique is not without complications, and a mild but statistically significant decline in pain levels from early to short term has been detected. Therefore, the long-term outcomes of this technique need to be investigated before we can advocate its routine use.

Abstract
INTRODUCTION Revision total hip arthroplasty (rTHA) is becoming a more common procedure due to the increasing volume of primary total hip arthroplasty. Diabetes mellitus (DM) is currently projected to affect 4.4% of the global population by 2030. Diabetes has been associated with poor outcomes for a variety of surgical interventions. However, the impact of insulin dependence has yet to be fully understood. The aim of this study was to determine the impact of insulin dependence on acute postoperative complications following rTHA. METHODS A retrospective cohort study was conducted using the American College of Surgeons National Quality Improvement Program database. All patients who underwent rTHA between 2006 and 2016 were identified and recorded as having non-insulin-dependent DM (NIDDM), insulin-dependent DM (IDDM) or no DM. Univariate and multivariate analysis were used to evaluate the incidence of multiple adverse events within 30 days after rTHA. RESULTS A total of 7685 patients were evaluated (No DM = 6651, NIDDM = 700, IDDM = 334). Univariate analysis revealed that all patients with DM had significantly higher incidences of postoperative complications (NIDDM: p < 0.001; IDDM: p < 0.001) and extended hospital length of stay (NIDDM: p = 0.015; IDDM: p < 0.0001). NIDDM was associated with increased rates of superficial surgical site infection (SSI) (p = 0.001), deep SSI (p = 0.038), and stroke (p = 0.013), while IDDM was associated with increased rates of pneumonia (p < 0.001), renal failure (p < 0.001), and postoperative transfusion (p < 0.001). On multivariate analysis, insulin-dependence was determined to be an independent risk factor for extended hospital length of stay (OR 1.905; 95% CI, 1.410-2.577; p < 0.001), pneumonia (OR 4.016; 95% CI, 1.799-8.929; p = 0.001), renal failure (OR 7.143; 95% CI, 2.203-23.256; p = 0.001) and postoperative transfusion (OR 1.366; 95% CI, 1.076-1.733; p = 0.01). CONCLUSIONS Insulin dependence is an independent risk factor for numerous short-term postoperative complications following rTHA. When assessing risk and planning perioperative management, surgeons should consider insulin-dependent diabetics as a sub-cohort within the diabetic population.

Abstract
INTRODUCTION In conjunction with impaction bone grafting (IBG), metal meshes have been proposed to minimise defects of the medial and superolateral walls in order to convert combined complex uncontained segmental defects into contained cavitary defects to facilitate IBG. METHODS The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews were queried for publications from January 1980 to March 2019 utilising keywords pertinent to total hip arthroplasty (THA), acetabular impaction bone grafting, clinical or functional outcomes, revision THA, or postoperative complications. RESULTS 7 articles were found to be suitable for inclusion in the present study. The mean modified Coleman methodology score for methodological deficiencies of the studies was 45.3 (range 38-59). Severe acetabular bone loss was present in 56% of cases having moderate bone loss in 18%, and mild in 26%. The all-cause reoperation rate was 7.4%, while the all-cause revision rate of the acetabular component was 6.2%. CONCLUSIONS IBG with mesh is effective for selected patients with acetabular bone defects. Most patients with moderate bone loss as well as selected patients with large superolateral defects can be successfully treated with IBG combined with mesh. There is limited data to show that IBG with mesh might be associated with decreased survival rates in patients with severe lateral defects (Paprosky IIIA) combined with ischial or medial wall osteolysis who require combined medial and lateral meshes. In addition, patients with severe superomedial migration of the cup (Paprosky IIIB) should not be treated with IBG and mesh.

Abstract
Despite growing evidence supporting the evaluation, classification, and treatment of acetabular bone loss in revision hip replacement, advancements have not been systematically incorporated into a single document, and therefore, a comprehensive review of the treatment of severe acetabular bone loss is needed. The Stavros Niarchos Foundation Complex Joint Reconstruction Center at Hospital for Special Surgery held an Acetabular Bone Loss Symposium on June 21, 2019, to answer the following questions: What are the trends, emerging technologies, and areas of future research related to the evaluation and management of acetabular bone loss in revision hip replacement? What constitutes the optimal workup and management strategies for acetabular bone loss? The 36 international experts convened were divided into groups, each assigned to discuss 1 of 4 topics: (1) preoperative planning and postoperative assessment; (2) implant selection, management of osteolysis, and management of massive bone loss; (3) the treatment challenges of pelvic discontinuity, periprosthetic joint infection, instability, and poor bone biology; and (4) the principles of reconstruction and classification of acetabular bone loss. Each group came to consensus, when possible, based on an extensive literature review. This document provides an overview of these 4 areas, the consensus each group arrived at, and directions for future research.

Abstract
Introduction Over the past two decades, Asia has experienced the rise and integration of Western medicine and digital health in its field of medicine. In this study, we investigated the trends in orthopaedic publications from three Asian countries: China, Japan, and Korea. Methods PubMed was used to measure the number of publications from China, Japan, and Korea in the past 21 years, from 1998 to 2020. The average percentage change in publications during this 21-year time period was analyzed using descriptive statistics. The average annual change in the number of publications from each country was also determined. One-way analysis of variance and two-group t-tests were utilized for statistical analyses with a p-value of <0.05 as the cut-off value for statistical significance. Results From years 1998 to 2020, there was a mean 35.5% ± 70.7% annual increase in the number of total publications from China, in comparison to a 5.1% ± 14.0% annual increase from Japan (p = 0.005) and a 27.3% ± 40.0% annual increase from Korea (p = 0.586). Conclusion For the past two decades, there has been a strong positive trend regarding the total number of orthopaedic publications from China. This finding might be related in part to an increased integration of Western medicine and the use of digital medicine, which followed a similar trend during the time period we analyzed. Korea and Japan also exhibited a positive trend in orthopaedic publications, which may be indicative of an improving educational system and greater general support for research.

Abstract
BACKGROUND There is growing evidence that cytokines and adipokines are associated with osteoarthritis (OA) severity, progression, and severity of associated pain. However, the cytokine response to total knee arthroplasty (TKA) and its association with persistent postoperative pain is not well understood. This study aims to describe the perioperative systemic (plasma) and local (synovial fluid) cytokine profiles of patients who do and do not develop persistent pain after TKA. METHODS Patients undergoing primary unilateral TKA for end-stage OA were prospectively enrolled. Demographic and clinical data were gathered preoperatively and postoperatively. Synovial fluid was collected pre arthrotomy and plasma was collected at multiple time points before and after surgery. Persistent postoperative pain (PPP) was defined as Numerical Rating Score≥4 at 6 months. Cytokine levels were measured using the V-Plex Human Cytokine 30-Plex Panel (Mesoscale-Rockville, Maryland, USA). Cytokine levels were compared between PPP and minimal pain groups. Given that the study outcomes are exploratory, no adjustment was performed for multiple testing. RESULTS Incidence of persistent pain at 6 months post TKA was 15/162 (9.3%). Postoperative plasma levels of four cytokines were significantly different in patients who developed persistent postoperative pain: interleukin (IL)-10, IL-1β, vascular endothelial growth factor, and IL12/IL23p40. Significantly lower IL-10 levels in the prearthrotomy synovial fluid were associated with development of postoperative persistent pain. CONCLUSIONS This prospective cohort study described a distinct acute perioperative inflammatory response profile in patients who developed persistent post-TKA pain, characterized by significant differences in four cytokines over the first 2 postoperative days. These results support the growing evidence that the patient-specific biologic response to surgery may influence longer-term clinical outcomes after TKA.

Preoperative Opioid Use Is Associated With Higher Revision Rates in Total Joint Arthroplasty: A Systematic Review. J Arthroplasty 2021; 36:3814-3821. [PMID: 34247870 DOI: 10.1016/j.arth.2021.06.017] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Revised: 06/06/2021] [Accepted: 06/17/2021] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Although preoperative opioid use has been associated with poor postoperative patient-reported outcome measures and delayed return to work in patients undergoing total joint arthroplasty, direct surgery-related complications in patients on chronic opioids are still not clear. Thus, we sought to perform a systematic review of the literature to evaluate the influence of preoperative opioid use on postoperative complications and revision following primary total joint arthroplasty. METHODS Following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we queried PubMed, EMBASE, the Cochrane Library, and the ISI Web of Science for studies investigating the influence of preoperative opioid use on postoperative complications following total hip arthroplasty and total knee arthroplasty up to May 2020. RESULTS After applying exclusion criteria, 10 studies were included in the analysis which represented 87,165 opioid users (OU) and 5,214,010 nonopioid users (NOU). The overall revision rate in the OU group was 4.79% (3846 of 80,303 patients) compared to 1.21% in the NOU group (43,719 of 3,613,211 patients). There was a higher risk of aseptic loosening (odds ratio [OR] 1.30, 95% confidence interval [CI] 1.11-1.53, P = .002), periprosthetic fractures (OR 1.89, 95% CI 1.53-2.34, P < .00001), and dislocations (OR 1.26, 95% CI 1.14-1.39, P < .00001) in the OU group compared to the NOU group. Overall, 5 of 6 studies reporting on periprosthetic joint infection (PJI) rates showed statistically significant correlation between preoperative opioid use and higher PJI rates. CONCLUSION There is strong evidence that preoperative opioid use is associated with a higher overall revision rate for aseptic loosening, periprosthetic fractures, and dislocation, and an increased risk for PJI.

Day case versus inpatient total shoulder arthroplasty: A systematic review and meta-analysis. Shoulder Elbow 2021; 13:471-481. [PMID: 34659480 PMCID: PMC8512977 DOI: 10.1177/1758573220944411] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 06/23/2020] [Accepted: 06/23/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND A number of papers have been published comparing the safety and efficacy of day case and inpatient anatomic or reverse total shoulder arthroplasty. However, no systematic review of the literature has been published to date. The aim of this review was to determine if day case total shoulder arthroplasty (length of stay <24 h) leads to similar outcomes as standard-stay inpatients (length of stay ≥24 h). METHODS The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviewers were queried for publications utilizing keywords that were pertinent to total shoulder arthroplasty, day case, outpatient and inpatient, clinical or functional outcomes, and complications. In order to determine the quantitative impact of day case total shoulder arthroplasty on readmission and revision rate, a meta-analysis was performed on articles that observed 30- or 90-day readmission or revision. RESULTS Eight articles were found to be suitable for inclusion in the present study which included 6103 day case total shoulder arthroplasty and 147,463 inpatient total shoulder arthroplasty. Following meta-analysis, there was no significant difference among patients who underwent day case total shoulder arthroplasty compared to inpatient total shoulder arthroplasty regarding revision rates (OR: 1.001; 95% CI: 0.721-1.389; p = 0.995) and 30-day readmission rates (OR: 0.940; 95% CI: 0.723-1.223; p = 0.646). In contrast, patients who underwent day case total shoulder arthroplasty were less likely to have a readmission within 90 days compared to their inpatient counterparts (OR: 0.839; 95% CI: 0.704-0.999; p = 0.049). Two out of eight studies reported comparable baseline clinical characteristics among groups, while five studies reported significant differences and one study did not provide information regarding clinical characteristics, such as medical comorbidities or American Society of Anaesthesiologists'(ASA) score. No significant difference among groups was found in all or almost all studies regarding mortality rates, and rates of cardiac complications, cerebrovascular events, thromboembolic events, pulmonary complications, cardiac complications, and nerve complications. Finally, results were rather conflicting regarding the correlation of day case total shoulder arthroplasty to the rate of surgical site infections. CONCLUSIONS This study showed that day case total shoulder arthroplasty might lead to similar rates of mortality, complications, revisions, and readmissions compared to inpatient total shoulder arthroplasty when used in a selected population of younger, healthier, and more male patients. In contrast, there was no consensus regarding the impact of day case total shoulder arthroplasty on the rate of surgical site infections. Finally, further research of higher quality is required to establish patient demographic criteria, ASA score, or comorbidity index cut off that might be used to define day case-treated patients who seem to have equivalent outcomes compared to inpatient-treated patients.Level of evidence: Systematic review of level III studies (lowest level included).

Clinical and radiographic outcomes of total shoulder arthroplasty with a partially cemented all-polyethylene pegged bone-ingrowth glenoid component: a systematic review. Shoulder Elbow 2021; 13:627-641. [PMID: 34804212 PMCID: PMC8600676 DOI: 10.1177/1758573220944168] [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: 02/02/2020] [Accepted: 06/21/2020] [Indexed: 11/15/2022]
Abstract
BACKGROUND Several articles have been published reporting on the clinical performance of a novel pegged, all-polyethylene glenoid component design which features a central peg, circumferentially fluted, interference-fit peg for tissue integration and three small peripheral pegs for cementing. However, no systematic review exists to this date. METHODS The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews were queried for publications up to May 2020. RESULTS Overall, 13 articles were included for analysis (560 operated shoulders, range of mean follow-up: 2-6 years). The survival rate was 98.2% (550 out of 560 cases), while the rate of aseptic loosening was 0.2% (1 out of 560 cases). There were 139 cases (out of 399 reported; 34.1%) with peri-glenoid radiolucency, and 35 cases (out of 223 reported; 15.7%) of asymptomatic central peg osteolysis, with 1 of them undergoing revision. CONCLUSIONS There was fair quality of evidence to show that partially cemented all-polyethylene pegged bone-ingrowth glenoid components produce promising results, with a low revision rate in the short- to medium-term follow-up. Nevertheless, this analysis showed high rates of both radiolucency of the glenoid component and osteolysis around the central peg which raise concern for potential failure of this glenoid component in the long-term follow-up.

Hip arthroscopy for hip osteoarthritis is associated with increased risk for revision after total hip arthroplasty. Hip Int 2021; 31:656-662. [PMID: 32126841 DOI: 10.1177/1120700020911043] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/04/2023]
Abstract
BACKGROUND It has not been determined yet whether hip arthroscopy (HA) leads to adverse outcomes after total hip arthroplasty (THA). The purpose of this study was to (1) determine 2-year conversion rate of HA done for osteoarthritis (OA) to THA and (2) explore the relationship between HA performed in patients with hip osteoarthritis and the risk of revision THA within 2 years of index arthroplasty. METHODS Data was collected from the Medicare Standardized Analytic Files insurance database using the PearlDiver Patient Records Database from 2005-2016. Patients were stratified into 2 groups based upon a history of hip arthroscopy prior to THA. RESULTS The 2-year conversion to THA rate for hip arthroscopy in patients with OA was 68.4% (95% CI, 66.2-70.6%). Multivariate analysis demonstrated that OA patients who underwent HA prior to THA were at an increased risk of revision surgery (OR 3.72; 95% CI, 3.15-4.57; p = 0.012), periprosthetic joint infection (OR 1.86; 95% CI, 1.26-2.77, p = 0.010) and aseptic loosening (OR 2.81; 95% CI, 1.66-4.76; p < 0.001) within 2 years of THA. CONCLUSIONS Analysis of a large insurance database found the conversion rate from HA performed in Medicare OA patients to THA within 2 years is unacceptably high. Hip arthroscopy prior to THA also significantly increased the risk of THA revision within 2 years after index THA. These results suggest that arthroscopic hip surgery should not be performed in patients with a diagnosis of OA as conversion rates are high and revision rates post THA are significantly increased.

How Does Contact Length Impact Titanium Tapered Splined Stem Stability: A Biomechanical Matched Pair Cadaveric Study. J Arthroplasty 2021; 36:3333-3339. [PMID: 33958253 DOI: 10.1016/j.arth.2021.04.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 04/09/2021] [Accepted: 04/14/2021] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Titanium tapered stems (TTS) achieve fixation in the femoral diaphysis and are commonly used in revision total hip arthroplasty. The initial stability of a TTS is critical, but the minimum contact length needed and impact of implant-specific taper angles on axial stability are unknown. This biomechanical study was performed to better guide operative decision-making by addressing these clinical questions. METHODS Two TTS with varying conical taper angles (2° spline taper vs 3.5° spline taper) were implanted in 9 right and left matched fresh human femora. The proximal femur was removed, and the remaining femoral diaphysis was prepared to allow for either a 2 cm (n = 6), 3 cm (n = 6), or 4 cm (n = 6) cortical contact length with each implanted stem. Stepwise axial load was then applied to a maximum of 2600N or until the femur fractured. Failure was defined as either subsidence >5 mm or femur fracture. RESULTS All 6 femora with 2 cm of stem-cortical contact length failed axial testing, a significantly higher failure rate (P < .02) than the 4 out of 6 femora and all 6 femora that passed testing at 3 cm and 4 cm, respectively, which were not statistically different from each other (P = .12). Taper angle did not influence success rates, as each matched pair either succeeded or failed at the tested contact length. CONCLUSION 4 cm of cortical contact length with a TTS demonstrates reliable initial axial stability, while 2 cm is insufficient regardless of taper angle. For 3 cm of cortical contact, successful initial fixation can be achieved in most cases with both taper angle designs.

Abstract
AIMS This study used an artificial neural network (ANN) model to determine the most important pre- and perioperative variables to predict same-day discharge in patients undergoing total knee arthroplasty (TKA). METHODS Data for this study were collected from the National Surgery Quality Improvement Program (NSQIP) database from the year 2018. Patients who received a primary, elective, unilateral TKA with a diagnosis of primary osteoarthritis were included. Demographic, preoperative, and intraoperative variables were analyzed. The ANN model was compared to a logistic regression model, which is a conventional machine-learning algorithm. Variables collected from 28,742 patients were analyzed based on their contribution to hospital length of stay. RESULTS The predictability of the ANN model, area under the curve (AUC) = 0.801, was similar to the logistic regression model (AUC = 0.796) and identified certain variables as important factors to predict same-day discharge. The ten most important factors favouring same-day discharge in the ANN model include preoperative sodium, preoperative international normalized ratio, BMI, age, anaesthesia type, operating time, dyspnoea status, functional status, race, anaemia status, and chronic obstructive pulmonary disease (COPD). Six of these variables were also found to be significant on logistic regression analysis. CONCLUSION Both ANN modelling and logistic regression analysis revealed clinically important factors in predicting patients who can undergo safely undergo same-day discharge from an outpatient TKA. The ANN model provides a beneficial approach to help determine which perioperative factors can predict same-day discharge as of 2018 perioperative recovery protocols.

Abstract
Recently, a variety of studies have analyzed the potential correlation between lumbar degenerative disease (LDD) and inferior clinical outcomes after total hip arthroplasty. However, there has been limited data concerning the role of LDD as a risk factor for failure after total knee arthroplasty (TKA). The aim of our study was to determine: (1) what is the association of LDDs with TKA failure (all-cause revision) within 2 years of index arthroplasty and (2) if patients with LDD and lumbar fusion are at increased risk of TKA revision within 2 years compared with LDD patients without fusion. Data were collected from the Humana insurance database using the PearlDiver database from 2007 to 2017. To assess aim 1, patients were stratified into two groups based on a prior history of LDD (International Classification of Diseases [ICD]-9 or -10 diagnostic codes). To analyze aim 2, patients within the LDD cohort were stratified based on the presence of lumbar fusion (lumbar fusion Current Procedural Terminology code). All-cause revision rate was 3.4% among LDD patients versus 2.4% of patients with non-LDD (p < 0.001) at 2 years. Following multivariate analysis, LDD patients were at increased risk of all-cause revision surgery at 2 years (odds ratio [OR]: 1.361; 95% confidence interval [CI]: 1.238-1.498; p < 0.001) as well as aseptic loosening (OR: 1.533; 95% CI: 1.328-1.768; p < 0.001), periprosthetic joint infection (OR: 1.245; 95% CI: 1.129-1.373; p < 0.001), and periprosthetic fracture (OR: 1.521; 95% CI: 1.229-1.884; p < 0.001). Among LDD patients, patients who have a lumbar fusion had an all-cause revision rate of 5.0%, compared with 3.2% among LDD with no lumbar fusion patients at 2 years (p = 0.021). Following multivariate analysis, lumbar fusion patients were at increased risk of all-cause revision surgery (OR: 1.402; 95% CI: 1.362-1.445; p = 0.028), aseptic loosening (OR: 1.432; 95% CI: 1.376-1.489; p = 0.042), and periprosthetic fracture (OR: 1.302; 95% CI: 1.218-1.392; p = 0.037). Based on these findings, TKA candidates with preoperative LDD should be counseled that TKA outcome may be impaired by the coexistence of lumbar spine degenerative disease. This is Level III therapeutic study.

Abstract
BACKGROUND Conversion total knee arthroplasty (TKA) may represent a more complex procedure compared with primary TKA. The purpose of this study was to compare 30-day complications between conversion TKA and primary, non-conversion TKA as well as between conversion TKA and revision TKA on a national scale using a multi-center surgical registry. METHODS Adult patients undergoing conversion TKA from 2006 to 2018 were identified in the National Surgical Quality Improvement Program database and were compared with patients who underwent primary TKA and aseptic revision TKA. In this analysis, 30-day complications were assessed. Bivariate analyses, including chi-squared and analysis of variance, and multivariate logistic regressions were performed. RESULTS Of 299,065 total patients undergoing knee arthroplasty, 1,310 (0.4%) underwent conversion TKA, 275,470 (92.1%) underwent primary TKA, and 22,285 (7.5%) underwent revision TKA. Following adjustment, patients who underwent conversion TKA were more likely to have increased risks of any complications (P < 0.001), mortality (P = 0.021), wound complications (P < 0.001), cardiac issues (P = 0.018), bleeding requiring transfusion (P < 0.001), and reoperation (P = 0.002) relative to primary TKA patients. Compared with patients who underwent revision TKA, conversion TKA patients were less likely to have septic complications (P = 0.009). CONCLUSION Conversion TKA is associated with significantly higher rates of complications compared with primary, non-conversion TKA, but less risk of sepsis compared with revision TKA. Because current reimbursement classifications do not account for the case complexity of a conversion TKA, new classifications should be implemented with reimbursements for conversion TKA approximating reimbursements for revision TKA.

Abstract
BACKGROUND Heterotopic ossification (HO) is abnormal growth of ectopic bone and negatively affects the outcomes after total knee arthroplasty (TKA). This systematic review and meta-analysis were performed to characterize the prevalence and severity of HO after primary TKA. METHODS A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Patient demographics, publication year, and HO prevalence after a primary TKA were recorded. A meta-analysis was performed to determine the overall prevalence of HO formation, and a subanalysis compared the studies published in different timeframes to determine whether a temporal effect exists for HO prevalence. RESULTS Two thousand nine hundred eighty-eight patients underwent primary TKA across the included studies. Fourteen percent of patients (9% to 20%; I2: 93.68%) developed HO postoperatively during a mean follow-up of 40.1 months (11 to 108 months). HO rates seemed to decrease in studies published in more recent years, with a pooled HO prevalence of 5% (0% to 13%; I2: 92.26%) among studies published in the past 15 years compared with 18% (12% to 25%; I2: 92.49%) among studies published before then. CONCLUSION Although studies reported a relatively low overall rate of HO after a primary TKA, the absence of a single, standardized classification system precludes the comparisons of HO severity between studies. Overall, HO prevalence seems to have decreased over time, likely reflecting the changes in perioperative medication protocols.

Abstract
Background Clinical outcomes of cemented femoral stems revisions using the cement-in-cement technique in aseptic conditions after total hip arthroplasty have been widely described. Methods The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews were queried. Results Twelve articles were included (620 revision THA). Revision rate for complications related to the femoral side was 1.4% at mid-term follow-up (5.4 years). Periprosthetic femoral fracture rate was 1.1%, aseptic loosening of the femoral component 0.3%. Conclusions Cement-in-cement revision technique of the femoral component is associated with a high mid-term success rates (98.6%) and is potentially less challenging than other revision techniques.

Abstract
Purpose
To answer the question whether bilateral reverse total shoulder arthroplasty (RTSA) is a safe and effective treatment which results in satisfactory clinical and functional outcomes with low complications rates. A second question to be answered was: what is the quality of the evidence of the already published studies which investigate the use of bilateral RTSA?
Methods
Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms “reverse” AND “total” AND “shoulder” AND “arthroplasty” AND “clinical.” Descriptive statistics were used to summarize the data.
Results
From the 394 initial studies we finally selected and assessed 6 clinical studies which were eligible to our inclusion–exclusion criteria. The aforementioned studies included in total 203 patients (69% females; mean age range: 67.1–75 years; mean follow-up range: 12–61 months). From those, 168 patients underwent staged bilateral RTSA (mean duration between first and second operation range: 8–21.6 months) and the rest of them a unilateral RTSA as controlled treatment. Almost all mean clinical and functional scores, which were used to assess the therapeutic value of bilateral RTSA, depicted significant postoperative improvement in comparison with the mean preoperative values. The modified Coleman methodology score, which was used to assess the quality of the studies, ranged from a minimum of 36/100 to a maximum of 55/100.
Conclusion
Despite the lack of high-quality evidence, staged bilateral RTSA seems to be a safe and effective procedure for patients with cuff tear arthropathy, which results in significantly improved clinical and functional outcomes and low reoperations' rates.

Use of elevated liners in primary total hip arthroplasty: a systematic review of the literature. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:587-594. [PMID: 34050816 DOI: 10.1007/s00590-021-03023-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Accepted: 04/25/2021] [Indexed: 11/30/2022]
Abstract
PURPOSE Instability remains one of the most frequent complications requiring revision surgery after primary total hip arthroplasty (THA). Elevated liners are often utilized to reduce the risk of dislocation; however, the literature is inconclusive, with no systematic reviews summarizing the data. Thus, this systematic review aimed to establish a consensus for the efficacy of elevated liners in primary THA by determining rates of overall revision and revision specifically for recurrent dislocation. MATERIALS AND METHODS This study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eligible randomized-controlled trials and observational studies reporting on the use of elevated liners in primary total hip arthroplasty were identified through May 2020. A random effects model meta-analysis was conducted, and the I2 statistic was used to assess for heterogeneity. RESULTS Eight studies met inclusion criteria, and overall, 26,507 patients undergoing primary THA with use of an elevated liner were included. In aggregate, the most common cause of revision was recurrent hip dislocation (1.3%, N = 82/6,267) followed by joint infection (1.2%, N = 45/3,772) and acetabular loosening (0.3%, N = 10/3,772). Notably, elevated liners were associated with a lower risk of revision for recurrent dislocation compared to neutral liners (HR: 0.74; 95% CI: 0.55-1.00; p = 0.048). CONCLUSION This review found that after primary THA with the use of elevated liners, hip dislocation and prosthetic joint infection continued to be the most frequent reasons for revision surgery. However, elevated liners had a lower risk of revision for recurrent dislocation compared to neutral liners.

Abstract
PURPOSE To measure the safe range of angles during tunnel drilling and map ideal patella tunnel placement with the use of preoperative computed tomography (CT) scan and compare results after medial patellofemoral ligament (MPFL) reconstruction using a hardware-free patellar fixation technique with two semi-patellar tunnels between a) a free-hand technique, and b) its modification with the use of an anterior cruciate ligament (ACL) tibia aiming device. METHODS CT scan was performed on 30 fresh-frozen cadaveric knees a) prior to any intervention and b) after MPFL reconstruction. For MPFL reconstruction, specimens were randomly allocated to 1) Group A, which consisted of knees operated with free-hand, hardware-free patellar fixation technique with two semi-patellar tunnels and 2) Group B, which consisted of knees operated on with a technique modification with the ACL tibia device. PATELLAR MEASUREMENTS L1 was the maximal patellar length. L2 was the minimum possible distance of placement for the upper tunnel from the proximal pole of the patella. The maximum bone bridge between tunnels was calculated as half of L1 minus the L2 distance (L1/2-L2). We also measured R1 and R2 angles at the proximal and distal tunnel that represent safe angles at the entry point during tunnel drilling (without breaching the anterior cortex or articular cartilage). RESULTS Preoperatively, mean L1 was 3.45 cm (range 3.05-4.52). Mean L2 was 0.62 cm (range 0.49-0.89). The mean maximum possible bone bridge between tunnels (L1/2-L2) was 1.1 cm (range 0.77-1.58). R1 was 6.050 (range 4.78-7.44), R2 was 6.640 (range 4.57-9.03), and their difference reached statistical significance (p = 0.03). Postoperatively, in group A, in 4 out of 15 patellas, multiple attempts were made during tunnel drilling in order to avoid anterior cortex or cartilage breaching. In group B, all tunnels were correctly drilled with the first attempt. Bone bridge between tunnels was significantly shorter postoperatively (0.93 cm, p < 0.01). CONCLUSION Small-size patellae correlate with short maximum bone bridge between tunnels, which makes anatomic, double-bundle, hardware-free patella fixation, with two semi-patellar tunnels MPFL reconstruction challenging. Furthermore, R angles create a narrow window to avoid intraoperative breaching, rendering the use of the ACL tibia device an extremely useful instrument. LEVEL OF EVIDENCE II.

Non-rigid fixation of the glenoid bone block for patients with recurrent anterior instability and major glenoid bone loss: A systematic review. Shoulder Elbow 2021; 13:168-180. [PMID: 33897848 PMCID: PMC8039760 DOI: 10.1177/1758573219872512] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2019] [Revised: 06/05/2019] [Accepted: 07/29/2019] [Indexed: 11/17/2022]
Abstract
BACKGROUND New types of glenoid bone block fixation, involving suture buttons, suture anchors or even implant-free impaction of the graft, have been recently introduced. In contrast to screws which allow for a rigid fixation of the bone block, these alternative procedures provide a non-rigid type of fixation. METHODS Two reviewers independently conducted the search in a systematic way (according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "Latarjet" OR "Eden-Hybbinette" OR "bone block" AND "anterior" AND "shoulder" AND "instability." RESULTS Eight out of the 325 initial studies were finally chosen according to our inclusion-exclusion criteria. In total, 750 patients were included in this review. The overall anterior instability recurrence rate for patients treated with non-rigid fixation was 2.6%, while the overall rate of non-union or graft osteolysis was 5.4%. CONCLUSIONS Regardless of the graft type, bone block non-rigid fixation showed satisfactory clinical and functional outcomes for the treatment of anterior shoulder instability with substantial glenoid bone deficiency. Furthermore, non-rigid fixation resulted in adequate bone graft healing and osseous incorporation. Lastly, given the relative lack of data, further prospective controlled studies are required to assess bone block non-rigid fixation procedures in comparison with the traditional rigid (with screws) fixation techniques.

Abstract
Crush injuries of the foot and ankle are uncommon and they have a poor prognosis leading to some form of disability. Degloving injuries of the heel and foot after crush injuries are rare and very challenging to manage due to the need for reconstruction of both osseous and soft tissue architecture. We present a salvage strategy for an open injury to the foot with extensive soft tissue detachment from the plantar and dorsal surface. A 30-year-old man was transferred to the Emergency Department from a neighboring hospital with a crush injury to the foot that had resulted in a degloving injury of the heel pad, after a motorcycle accident. The patient had a 20 cm circumferential wound that was extending from dorsal to the plantar surface along with rupture of the extensor digitorum longus (EDL) tendons and transection of the superficial peroneal nerve. There was an extensive detachment of soft tissues from the deep fascia and bones, whereas the posterior tibial artery was intact. In radiographic imaging, a small inferior avulsion fracture of the calcaneus along with fractures of the cuneiform bones was revealed. The initial management involved thorough surgical debridement, removal of necrotic tissues, repair of EDL tendons and fracture stabilization. Negative-pressure wound therapy was also applied for six weeks. Subsequently, a split-thickness skin graft was used to cover the skin defect. Six months after injury, the patient had a normal range of motion, intact sensation over the sole and could ambulate independently. Although the majority of heel pad degloving injuries have a poor prognosis, there are positive prognostic factors as presented in the current case for a satisfying functional final outcome, which include vascular intergrity, fracture stabilization, soft-tissue reconstruction with negative pressure wound therapy, and application of skin grafts.

Comparison between all-suture and biocomposite anchors in the arthroscopic treatment of traumatic anterior shoulder instability: A retrospective cohort study. J Orthop 2021; 24:264-270. [PMID: 33867751 DOI: 10.1016/j.jor.2021.03.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 02/01/2021] [Accepted: 03/23/2021] [Indexed: 10/21/2022] Open
Abstract
Purpose Suture anchors have revolutionized arthroscopic surgery, enabling direct soft tissue-to-bone repair. There are many types of anchors still used in arthroscopic shoulder operations. We sought to compare the clinical outcome of all-suture and biocomposite anchors when used in arthroscopic Bankart repair for patients suffering from anterior shoulder instability. Methods A single-center retrospective cohort study of 30 patients (mean age: 26.6 years, SD: 8.8 years, male/female ratio: 5/1, mean follow up: 28 months, SD: 23.8, range: 12-92) with anterior shoulder instability was conducted. Patients were divided into 2 groups based upon the type of suture anchors used for the Bankart repair: group A (14 patients) used only all-suture anchors and group B (16 patients) used only biocomposite anchors. Outcomes reported were postoperative dislocations, positive shoulder apprehension test, self-reported sense of shoulder instability, return to activities of daily living, return to sports, patient satisfaction and complications. Patient reported outcome measures (PROMs) used were the Rowe Score for Instability, Constant Shoulder Score, Walch Duplay Score, The American Shoulder and Elbow Surgeons (ASES) Shoulder Score, Oxford Shoulder Instability Score and external rotation at 90° of arm abduction, external rotation at 0° of arm abduction, forward flexion, abduction, adduction and internal rotation. Results Rates of postoperative shoulder dislocation demonstrated no significant difference between the 2 groups (p > .05). Four postoperative dislocations happened, two in each group (14.3% and 12.5% for all suture only and biocomposite only groups, respectively), with three of them being traumatic. In addition, no significant differences were observed amongst groups regarding shoulder apprehension test (group A: 85.7% vs. group B: 93.8%), sense of shoulder instability (7.1% vs. 6.3%), return to activities of daily living (group A: 85.7% vs. group B: 93.8%), return to sports (group A: 85.7% vs. group B: 87.5%), patient satisfaction (moderate level: group A 21.4% vs. group B 12.5%), and PROMs. Conclusion The short-term failure rate and clinical/functional outcomes of arthroscopic Bankart repair using all-suture anchors is similar to the use of biocompatible anchors.

Abstract
Purpose The purpose is to identify the impact of operation time length on complications for patients undergoing operative treatment of distal radius fracture. Methods Patients who underwent operative treatments for distal radius fractures were identified in a national database. Data collected include patient demographic information, comorbidities, and complications. Results Operation time was found to be an independent predictor for return to the operating room. Operation time was not found to be a predictor of other postoperative complications. Conclusion Surgeons should work to shorten procedure duration whenever possible to minimize the risks that longer operative times can have on patient outcomes.

Abstract
Purpose Simultaneous bilateral unicompartmentsl knee arthroplasty (BUKA) is considered safe and effective. We performed a systematic review to assess the postoperative outcomes. Methods The US National Library of Medicine (PubMed/MEDLINE), Google Scholar, and the Cochrane Database of Systematic Reviews were queried for publications. Results Ten articles were included with 765 simultaneous BUKA. Overall complication rate was 7.0%, survivorship was 97.6% at mean 17 months follow-up. No differences were reported between simultaneous and staged BUKA. Conclusion Simultaneous BUKA is as safe as staged BUKA, it is associated with decreased length of stay and operative time, although it has an increased rate of blood transfusion.

Abstract
CASE A 54-year-old man presented with low back pain and low-grade fever. Palpation revealed a focal mass of the lumbar region. Radiographs were normal, but magnetic resonance imaging demonstrated a multicystic mass at the level of L2-L4. The initial diagnosis of a hydatid cyst was confirmed after surgical excision. CONCLUSION Although primary paraspinal hydatidosis is rare, physicians should be aware of it when dealing with patients suffering from low back pain combined with red-flag symptoms. Especially in rural regions or areas where populations live in close proximity to host animals, primary paraspinal hydatidosis should be included in the differential diagnosis.

Modern trabecular metal-backed glenoid components in total shoulder arthroplasty: What is the evidence? A systematic review. Shoulder Elbow 2021; 13:29-37. [PMID: 33717216 PMCID: PMC7905522 DOI: 10.1177/1758573220914277] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Revised: 02/28/2020] [Accepted: 02/29/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND A number of papers have been published reporting on the clinical performance of modern trabecular metal-backed glenoid components in total shoulder arthroplasty. However, no systematic review of the literature has been published to date. METHODS The US National Library of Medicine (PubMed/MEDLINE), and the Cochrane Database of Systematic Reviews and EMBASE were queried for publications from January 1980 to October 2019 utilizing keywords pertinent to total shoulder arthroplasty, trabecular metal, and clinical outcomes. RESULTS Overall, seven articles were included for analysis (322 operated shoulders, mean follow-up range: 2-4 years). The survival rate of modern trabecular metal-backed glenoid components was 96% (309 out of 322 cases) at 43 months mean follow-up, while the rate of aseptic loosening was 0.3% (1 out of 322 cases). There were 35 cases (10.9%) with glenoid component radiolucency (one of them required revision), and 37 cases (11.5%) of metal debris formation, with four of them undergoing revision. CONCLUSIONS There was low quality evidence to show that the use of modern trabecular metal-backed glenoid components in total shoulder arthroplasty may be safe and effective at short-term follow-up. However, this analysis showed alarmingly high rates of both radiolucency of the glenoid component and metal debris formation which raise concern for potential failure of this glenoid component in the long term. Therefore, we feel that modern trabecular metal-backed glenoid components should be still used with caution as part of a structured surveillance or research program until we know if there is a detriment to the prosthesis in the medium to long term.Level: Systematic review, IV.

Abstract
This study was performed to determine whether Autologous Matrix-Induced Chondrogenesis (AMIC) is an effective and safe treatment option for patients with symptomatic Osteochondral defects of the Talus (OCTs) and to identify factors that influence the clinical outcome. A systematic review of the literature was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three reviewers independently conducted the literature search using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. The databases were queried using the terms “autologous” AND “matrix” AND “induced” AND “chondrogenesis.” Thirteen studies were eligible for review. All studies that compared the preoperative and postoperative mean values of different clinical/functional scores showed significant clinical improvement. The final postoperative mean Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score ranged from 50.9 to 74.5. The included studies indicated that age and body mass index may have a detrimental impact on the postoperative outcome. A higher re-intervention rate is expected with the open technique, mainly because of hardware removal after malleolar osteotomy. This data analysis demonstrated that both arthroscopic and open AMIC procedures are effective and safe for the treatment of OCTs. Level IV, systematic review of therapeutic studies

Reconstruction of the medial patellofemoral ligament using two blind transverse semi-patella tunnels and an implant-free technique for patellar fixation: a technical note. J Orthop Surg Res 2021; 16:25. [PMID: 33413498 PMCID: PMC7791973 DOI: 10.1186/s13018-020-02161-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 12/14/2020] [Indexed: 11/26/2022] Open
Abstract
Background The double-bundle technique with two points of patellar fixation in the upper half of the patella replicating the broad attachment site of the native medial patellofemoral ligament (MPFL) is the most commonly performed procedure for MPFL reconstruction. Complete transverse patella tunnels pose a threat to the integrity of the patella. We present an implant-free, double-bundle technique for MPFL reconstruction with gracilis autograft, overcoming the problem of complete patella bone tunnels and over-drilling. Methods After standard gracilis graft harvesting, the anteromedial side of the patella is exposed. With the guidance of an anterior-cruciate-ligament (ACL) tibia-aiming device, two 2-mm parallel guide pins are inserted from medial to lateral at the upper half of the patella. The two guide pins are over-drilled with a cannulated 4.5-mm drill bit 2-cm deep, to create two transverse blind semi-patellar tunnels. For the femoral fixation, a 2.4-mm guide pin with an eyelet is drilled at the Schöttle point and over-reamed with a 6-mm cannulated reamer to a depth of 30 mm. The two free ends of the graft (with two running Krakow sutures placed) are pulled into the two patella tunnels and the graft sutures are tied together with tension for stable graft fixation at the lateral patella rim. With the help of a femoral suture loop (which is inserted in the femoral bone tunnel), the graft-loop is advanced into the femoral bone tunnel and the graft is finally fixed with a 7-mm interference screw at 30° of knee flexion. Results The utilization of blind transverse tunnels (not trans-patellar tunnels) offers the advantage of avoiding stress risers at the patella. Thanks to the ACL tibia aiming device, multiple drilling, and breaching of the anterior patellar cortex or articular surface of the patella is avoided. Conclusions This implant-free, and consequently affordable technique, isolated or combined with bony procedures, minimizes possibilities for perioperative bony complications at the patella fixation site.

Abstract
Various systematic reviews have recently shown that intra-articular platelet-rich plasma (IA-PRP) can lead to symptomatic relief of knee osteoarthritis for up to 12 months. There exist limited data on its use in small joints, such as the trapeziometacarpal joint (TMJ) or carpometacarpal joint (CMCJ) of the thumb. A prospective, randomized, blind, controlled, clinical trial of 33 patients with clinical and radiographic osteoarthritis of the TMJ (grades: I-III according to the Eaton and Littler classification) was conducted. Group A patients (16 patients) received 2 ultrasound-guided IA-PRP injections, while group B patients (17 patients) received 2 ultrasound-guided intra-articular methylprednisolone and lidocaine injections at a 2-week interval. Patients were evaluated prior to and at 3 and 12 months after the second injection using the visual analogue scale (VAS) 100/100, shortened Disabilities of the Arm, Shoulder, and Hand Questionnaire (Q-DASH), and patient's subjective satisfaction. No significant differences between the baseline clinical and demographic characteristics of the 2 groups were identified. After 12 months' follow-up, the IA-PRP treatment has yielded significantly better results in comparison with the corticosteroids, in terms of VAS score (P = 0.015), Q-DASH score (P = 0.025), and patients' satisfaction (P = 0.002). Corticosteroids offer short-term relief of symptoms, but IA-PRP might achieve a lasting effect of up to 12 months in the treatment of early to moderate symptomatic TMJ arthritis.

Abstract
Given the growing rate of revision total knee arthroplasties (TKAs), it is important to understand the potential risk factors associated with postoperative complications. The aim of this study was to determine the role of operative time in postoperative complications in revision TKA. A retrospective cohort study was performed using data from the American College of Surgeons National Surgical Quality Improvement Program database. Patients who had undergone revision TKA between 2007 and 2016 were identified and analyzed based on operative time. The effect of operative time on postoperative complications was examined using multinomial multivariate analysis. A total of 14,769 revision TKA patients were included. On adjusted multivariate analysis, each additional 15 minutes of operative time increased the likelihood of wound complications (odds ratio, 1.023; P=.020), postoperative blood transfusion (odds ratio, 1.169; P<.001), and extended hospital stay (odds ratio, 1.060; P<.001). An increase of 15 minutes of operative time was associated with several postoperative complications. Although operative time is often an uncontrollable factor, surgeons should consider the effect of prolonged operative time on potential complications in the acute postoperative period.

Abstract
INTRODUCTION Short femoral stems were designed to bridge the gap between conventional straight design stems and hip resurfacing prostheses in total hip arthroplasty (THA). A number of clinical trials have been recently conducted to assess the clinical and safety profile of the cementless, colarless, tapered Metha short hip stem in young or active middle-aged individuals. METHODS A systematic scoping review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. 4 reviewers independently conducted the search using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "short" AND "hip" AND "stem". RESULTS From the initial 773 studies we finally chose 12 studies after applying our inclusion-exclusion criteria. The number of operated hips that were included in these studies was 5048 (mean BMI range: 22.7-35.2, mean age range: 44.4-60.4 years, mean follow-up range: 2-9 years). The mean modified Coleman methodology score was 52.3/100, while it ranged from 31/100 to 63/100. All mean clinical outcome scores that were used in the studies illustrated significant postoperative improvement when compared with the respective initial values. The revision rate of the Metha stem for component-related reasons was 2.5%, while the rate of major complications not requiring revision of the Metha stem was 2.8%. CONCLUSIONS The Metha stem performs well in young or active middle-aged THA patients. Further studies are required for the assessment of the long-term results.

Abstract
OBJECTIVE The aim of this study was to determine the incidence of hand disorders in a general rural area, record the demographic characteristics for each condition, and evaluate the tendencies overtime in the incidence of these conditions. METHODS Using nationwide census data, we identified a health network system serving a geographic area with stable population. Subsequently, we retrospectively analyzed all the patient records (n=731 patients) with hand disorders documented between 2001 and 2015. We performed a retrospective review and collected demographic data for the patients and disorders treated surgically. We calculated the incidence of these conditions based on the census data and performed qualitative and categorical analysis with different demographic and disease-related variables. RESULTS We reviewed surgically treated 204 male and 527 female patients with hand disorders. The mean annual incidence was 222.5 cases per 100,000 individuals per year. More than 55% of the patients were between 50 and 69 years old. Trigger finger (TF) accounted for approximately 42% of patients, followed by 35% with carpal tunnel syndrome (CTS). TF and CTS were related to hand dominance, and right hand was affected in 53.4% of the patients. CONCLUSION Hand disorders in a rural area seem to correlate with the occupational sector activities, such as farming and agriculture. CTS was the most common disorder in the past; however, the dramatic increase in the incidence rate of TF made it the most common hand disorder in the last decade. Incidence rates in both males and females showed an increasing trend.

Outcomes and Risk Factors of Extended Trochanteric Osteotomy in Aseptic Revision Total Hip Arthroplasty: A Systematic Review. J Arthroplasty 2020; 35:3410-3416. [PMID: 32800436 DOI: 10.1016/j.arth.2020.07.034] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 06/08/2020] [Accepted: 07/13/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Although extended trochanteric osteotomy (ETO) is an effective technique for femoral stem removal and for the concomitant management of proximal femoral deformities, complications including persistent pain, trochanteric nonunion, and painful hardware can occur. METHODS The US National Library of Medicine (PubMed/MEDLINE) and the Cochrane Database of Systematic Reviews were queried for publications utilizing the following keywords: "extended" AND "trochanteric" AND "osteotomy." RESULTS Nineteen articles were included in the present study with 1478 ETOs. The mean overall union rate of the ETO was 93.1% (1377 of 1478 cases), while the overall rate of radiographic femoral stem subsidence >5 mm was 7.1% (25 of 350 cases). ETO union rates and femoral stem subsidence rates were similar between patients with periprosthetic fractures treated with total hip arthroplasty (THA) revision and ETO and patients treated with THA revision and ETO for reasons other than fractures. There was limited evidence that prior femoral cementation and older age might negatively influence ETO union rates. CONCLUSION There was moderate quality evidence to show that the use of ETO in aseptic patients undergoing single-stage revision THA is safe and effective, with a 7% rate of ETO nonunion and subsidence >5 mm in 7%. ETO can be safely used in cases with periprosthetic fractures in which stem fixation is jeopardized and a reimplantation is required. A well-conducted ETO should be preferred in selective THA revision cases to prevent intraoperative femoral fractures which are associated with deteriorated clinical outcomes. The use of trochanteric plate with cables should be considered as the first choice for ETO fixation.

Cervical spine degenerative disease is an independent risk factor for increased revision rate following total knee arthroplasty. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2020; 31:511-516. [PMID: 33026564 DOI: 10.1007/s00590-020-02799-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Accepted: 09/22/2020] [Indexed: 11/30/2022]
Abstract
INTRODUCTION The relationship between cervical degenerative pathology and total knee arthroplasty (TKA) revision rates is not well understood. The aim of the study was to determine whether cervical spine degenerative diseases have a role in complications following TKA within 2 years. METHODS Data were collected from the Humana insurance database using the PearlDiver Patient Records Database from 2007-2017. Patients who had a primary TKA were identified using Current Procedural Terminology (CPT) code 27,447, and patients with degenerative cervical disease were identified using CPT and International Classification of Diseases (ICD) codes. Data on patients' demographics, comorbidities and postoperative complications were recorded and analyzed with univariate and multivariate analysis with significance set at p < 0.05. A Kaplan-Meier analysis was conducted to estimate the 1- and 2-year rates of survival free from revision. RESULTS A total of 81,873 patients were included in this study. Following multivariate analysis, cervical spine degenerative disease patients were at increased risk of all-cause revision surgery following 1 year (OR: 1.342 95% CI: 1.149-1.569; p < 0.001) and 2 year (OR: 1.338; 95% CI: 1.184-1.512; p < 0.001). At 2 years, patients with cervical spine degenerative disease had a survival rate of 97.7%, while the survival rate was 99.2% among the non-cervical degenerative cohort. CONCLUSIONS Based on these results, patients with cervical spine degenerative pathology should be counseled that their spinal pathology may impair outcomes following TKA.

Reliability and Validity of Acetabular and Femoral Bone Loss Classification Systems in Total Hip Arthroplasty: A Systematic Review. HSS J 2020; 16:288-295. [PMID: 33088242 PMCID: PMC7534882 DOI: 10.1007/s11420-020-09766-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Accepted: 05/25/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND A variety of classification systems have been developed to help surgeons treat patients with acetabular or femoral bone loss in total hip arthroplasty, yet no "gold standard" for classification has been agreed upon. Furthermore, the reliability and validity of the available classification systems remain unknown. QUESTIONS/PURPOSE The aims of our study were to determine the reliability and validity of the three most common acetabular and femoral bone loss classification systems (Paprosky, American Academy of Orthopaedic Surgeons [AAOS], and Saleh and Gross). METHODS A systematic review of the literature was performed to identify studies that reported on the reliability or validity (or both) of the acetabular and femoral components of the three bone loss classification systems. RESULTS In all, seven articles met our inclusion criteria. Six studies reported on the reliability (all six studies) or validity (three studies) of acetabular bone loss rating systems (286 acetabula), and five analyzed reliability (all five studies) or validity (three studies) of femoral bone loss classification systems (364 femurs). In studies in which either the Paprosky or AAOS acetabular bone loss classifications were used, the classification systems were considered unreliable in 75% and 100% of them, respectively. On the femoral side, the Paprosky classification demonstrated moderate interobserver and good intraobserver reliability. The AAOS femoral bone classification was found to have good intraobserver reliability but poor interobserver reliability. The Saleh and Gross acetabular and femoral bone loss classification systems yielded mixed results, but each was considered reliable in one of the studies looking at these aspects of the systems. CONCLUSION Although surgical techniques, treatment options, and advanced imaging available to the surgeon have evolved over the past few decades, the acetabular and femoral bone loss classification systems, first developed in the 1990s, have remained largely unchanged. Our results indicate that improvements to these systems are necessary in order for them to be as useful as possible in planning the surgical course.

Sustained benefit of autologous matrix-induced chondrogenesis for hip cartilage repair in a recreational athletic population. Knee Surg Sports Traumatol Arthrosc 2020; 28:2309-2315. [PMID: 31781800 DOI: 10.1007/s00167-019-05801-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2019] [Accepted: 11/12/2019] [Indexed: 11/26/2022]
Abstract
PURPOSE To investigate the clinical outcome of autologous matrix-induced chondrogenesis (AMIC) implementation for mid-sized chondral lesions of the acetabulum in young active patients, and assess their potential to resume an active lifestyle including return to recreational athletic activities. METHODS Sixty-two patients with full-thickness mid-sized acetabular chondral lesions were studied. All patients who underwent an arthroscopic AMIC procedure for reconstruction of chondral defects were assessed pre-operatively and at least 2 years post-operatively using the Hip disability and Osteoarthritis Outcome Score (HOOS), modified Harris Hip Score (mHHS) and Visual Analog Scale (VAS) for pain. RESULTS A significant improvement in all three scores at the time of follow-up was found. The mean HOOS improved from 58.8 ± 7.4 pre-operatively to 90.6 ± 7.1 at follow-up (p < 0.001) while the mean mHHS improved from 53.4 ± 6.6 to 82.4 ± 8.2 (p < 0.001). There was a significant decrease from 4.9 ± 1.1 pre-operatively to 1.1 ± 0.8 post-operatively (p < 0.001) in the VAS pain evaluation, indicating that the patients were satisfied with their relief of pain. CONCLUSIONS The AMIC procedure is an effective single-stage technique for the reconstruction of mid-size chondral defects of acetabulum in amateur athletes. This intervention enhanced the potential for patients to resume recreational athletic activities and the 2-year clinical outcome as evaluated by the HOOS, mHHS and VAS showed significant improvement over the pre-operative evaluations.

What are the benefits of robotic-assisted total knee arthroplasty over conventional manual total knee arthroplasty? A systematic review of comparative studies. Orthop Rev (Pavia) 2020; 12:8657. [PMID: 32913593 PMCID: PMC7459388 DOI: 10.4081/or.2020.8657] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 06/17/2020] [Indexed: 12/20/2022] Open
Abstract
Total knee arthroplasty (TKA) is a highly successful operation that improves patients' quality of life and functionality. Yet, up to 20% of TKA patients remain unsatisfied with the functional outcomes. Robotic TKA has gained increased attention and popularity in order to improve patient satisfaction and implant survivorship by increasing accuracy and precision of component implantation. The current systematic review was run in order to compare implant survivorship, complication rates, clinical outcomes, and radiological outcomes between robotic-assisted TKA (RA) and conventional manual TKA (CM). Articles were referenced from the US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews. Nine comparative studies with 1199 operated knees in 1159 patients were included, 614 underwent active or semiactive robotic-assisted TKA compared to 585 CM-TKA. Improvements in the RA group were reported for early functional outcomes, radiographic outliers (RA 16% vs CM 76%) and radiolucent lines (RA 0% vs CM 35%). No significant differences between the two groups were reported in overall survivorship (RA 98.3% vs CM 97.3%), complication rate (RA 2.4% vs CM 1.4%) and operative time (RA 88 min vs CM 79 min). Despite higher costs, roboticassisted TKA offers better short-term clinical outcomes when compared to conventional manual technique with reduction in radiographic outliers and reduced risks of iatrogenic soft tissues injuries (reduced blood loss and postoperative drainage). Further high-quality long-term studies of modern robotic systems are required in order to evaluate how the increased accuracy and reduced outliers affect the long-term survivorship of the implants and the clinical outcomes.

Operative time greater than 120 minutes is associated with increased pulmonary and thromboembolic complications following revision total hip arthroplasty. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2020; 30:1393-1400. [PMID: 32524203 DOI: 10.1007/s00590-020-02712-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 05/31/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND The aim of this study was to determine the impact of operative time on the development of early postoperative complications in patients undergoing revision total hip arthroplasty (THA). METHODS In this retrospective cohort study, data were collected through the American College of Surgeons National Quality Improvement Program Database. All patients who underwent revision THA between 2007 and 2016 were identified and stratified into groups based on operative time|: 0-60 min, 61-120 min, 121-180 min, and > 180 min. The incidence of early postoperative adverse events with 30 days, including cardiac, pulmonary, renal, septic, thromboembolic, urinary tract, and wound complications, death, length of stay > 7 days, and unplanned return to the operating room were collected. The complications rates following revision THA were evaluated with univariate and multivariate analyses with significance set at p < 0.05. RESULTS A total of 6271 revision THA patients were included for analysis. Patients who had > 120 min of operative time had a significantly increased risk of the development of pulmonary (OR: 1.339; 95% CI: 1.08-1.661; p = 0.008) and thromboembolic complications (OR: 1.34; 95% CI: 1.053-1.707; p = 0.017) and also had an extended length of stay greater than 7 days (OR: 1.413; 95% CI: 1.295-1.541; p < 0.001). CONCLUSIONS Increased operative time (> 120 min) during revision THA is associated with increased risk of pulmonary and thromboembolic complications, and prolonged hospitalizations (greater than seven days).

Hospital Discharge Within a Day After Total Hip Arthroplasty Does Not Compromise 1-Year Outcomes Compared With Rapid Discharge: An Analysis of an Insurance Claims Database. J Arthroplasty 2020; 35:S107-S112. [PMID: 31785964 DOI: 10.1016/j.arth.2019.10.059] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 10/25/2019] [Accepted: 10/30/2019] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND As health care costs continue to rise, same-day and rapid discharge have become popular options for total hip arthroplasty (THA). However, it remains unclear if there is a difference between within-a-day discharge and early discharge for 1-year clinical outcomes. METHODS Data were collected from the Humana insurance database using the PearlDiver Patient Records Database from 2007 to 2017, identifying patients receiving a primary THA. Patients were then stratified into three groups: (1) discharge within a day (length of stay [LOS] <24 hours), (2) rapid discharge (LOS: 1-2 days), and (3) traditional discharge (LOS: 3-4 days). The outcomes assessed were all-cause revision surgery, periprosthetic joint infection, prosthetic loosening, prosthetic dislocation, and periprosthetic fracture at 1 year postoperatively. RESULTS In total, 40,038 patients met inclusion criteria. Among those, 754 (1.88%) patients were discharged within a day, 13,670 (34.14%) patients were in the rapid discharge cohort, and 25,614 (63.97%) patients were in the traditional discharge cohort. After multivariate analysis, no significant differences were observed between the within-a-day discharge group and either the rapid discharge or the traditional discharge group. Rapid discharge patients were at decreased risk of periprosthetic joint infection (odds ratios: 0.747, 95% confidence interval: 0.623-0.896) and readmission (odds ratios: 0.778; 95% confidence interval: 0.735-0.824, P < .001) compared with traditional discharge patients. CONCLUSIONS No significant differences were observed in the one-year outcomes of primary THA between within-a-day discharge patients, rapid discharge, and traditional discharge. For those that qualify after careful selection, outpatient THA might be a feasible alternative to the traditional inpatient THA.

Highly Porous Titanium Acetabular Components in Primary and Revision Total Hip Arthroplasty: A Systematic Review. J Arthroplasty 2020; 35:1737-1749. [PMID: 32070658 DOI: 10.1016/j.arth.2020.01.052] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 12/13/2019] [Accepted: 01/20/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND A number of papers have been published reporting on the clinical performance of highly porous coated titanium acetabular cups in primary and revision total hip arthroplasty (THA). However, no systematic review of the literature has been published to date. METHODS The US National Library of Medicine (PubMed/MEDLINE), Embase, and the Cochrane Database of Systematic Reviews were queried for publications utilizing the following keywords: "tritanium" OR "highly-porous" AND "titanium" OR "acetabular" AND "trabecular" AND "titanium". RESULTS Overall, 16 studies were included in this review (11,366 cases; 60% females, 2-7 years mean follow-up). The overall survival rate of highly porous titanium acetabular components in primary cases was 99.3% (10,811 of 10,886 cases), whereas the rate of aseptic loosening was 0.1%. The overall survival rate of the highly porous titanium acetabular components in revision THA cases was 93.5% (449 of 480 cases), whereas the rate of aseptic loosening was 2.1%. CONCLUSION There was moderate quality evidence to show that the use of highly porous titanium acetabular components in primary and revision THA cases is associated with satisfactory clinical outcomes in the short- and medium-term, without showing any evidence of cup migration or radiolucency. Taking into consideration that there is no evidence yet regarding the long-term survivorship of these components, we feel that further research of higher quality is required to generate more evidence-based conclusions regarding the longevity of highly porous titanium acetabular implants compared with conventional titanium counterparts.
