Risk Factors of Emergency Department Utilization After Outpatient Surgery for Sports-Related Injuries

INTRODUCTION

The purpose of this study was to identify the most common reasons for and risk factors associated with postoperative emergency department (ED) utilization after orthopaedic procedures for sports-related injuries.

METHODS

Using the 2014 to 2016 New York and Florida State Databases from the Healthcare Cost and Utilization Project, outpatient procedures for sports-related injuries were identified. Patient records were tracked across care settings within each state to determine the rate and reasons of postoperative ED utilization within 90 days after the index surgery. Multiple logistic regression models were used to identify risk factors associated with ED visits at 0 to 7 days, 8 to 30 days, 31 to 90 days postoperatively.

RESULTS

A total of 28,192 surgery visits for sports-related injuries were identified, with knee arthroscopy with partial meniscectomy (18.48%) and arthroscopic anterior cruciate ligament reconstruction (17.04%) as the two most common procedures treating sports injuries. The overall postoperative ED utilization rates were 1.6% (0 to 7 days postoperative), 1.3% (8 to 30 days) and 2.1% (31 to 90 days). The main cause of ED visits was markedly different during each postoperative period: mainly musculoskeletal pain (36.3%) during 0 to 7 days, either musculoskeletal pain (17%) or injury (16.6%) during 8 to 30 days, and injury (24.2%) during 31 to 90 days. Sports with the highest ED utilization in descending order were basketball, football, ice/snow sports, walking/running, cycling, and soccer. Relative to open procedures, arthroscopic procedures were 0.71 times as likely to result in a postoperative ED visit. Independent predictors of ED utilization up to 90 days postoperatively included renal failure, chronic pulmonary disease, psychosis, diabetes, and alcohol abuse.

DISCUSSION

Rate of ED utilization after outpatient surgery for sports-related injuries is low (<2.2%), with postoperative musculoskeletal pain and reinjury as the two most common causes, highlighting the importance of postoperative pain management and injury prevention. Arthroscopic procedures showed markedly lower ED utilization compared with open surgery, although not indicative of overall superiority.

Syndesmosis Injury Contributes a Large Negative Effect on Clinical Outcomes: A Systematic Review

INTRODUCTION

The literature largely addresses questions of diagnostic accuracy and therapeutic accuracy. However, the magnitude of the clinical impact of syndesmosis injury is commonly described in intuitive yet qualitative terms. This systematic review aimed to quantify the impact of syndesmosis injury.

METHODS

Published clinical outcomes data were used to compute an effect size reflecting the impact of syndesmosis injury. This was done within the clinical contexts of isolated syndesmosis injury and syndesmosis injury with concomitant ankle fracture. Clinical outcomes data included Olerud-Molander (OM) and American Orthopaedic Foot and Ankle Society (AOFAS) scores, visual analog scale for pain, and days missed from sport competition. Parametric data were compared with Student t tests. Effect size was computed using Cohen's d.

RESULTS

In ankle fracture patients, syndesmosis injury demonstrated a large effect size for OM (d = 0.96) and AOFAS (d = 0.83) scores. In athletic populations without concomitant ankle fracture, syndesmosis injury demonstrated a large effect size on days missed from competition (d = 2.32).

DISCUSSION

These findings confirm the magnitude of the negative impact of syndesmosis injury in athletic populations with isolated injury and in ankle fracture patients. In ankle fracture patients, this large negative effect remains despite surgery. Thus, syndesmosis repair may not fully mitigate the impact of the injury.

ChatGPT Provides Unsatisfactory Responses to Frequently Asked Questions Regarding Anterior Cruciate Ligament Reconstruction

PURPOSE

To determine whether the free online artificial intelligence platform ChatGPT could accurately, adequately, and appropriately answer questions regarding anterior cruciate ligament (ACL) reconstruction surgery.

METHODS

A list of 10 questions about ACL surgery was created based on a review of frequently asked questions that appeared on websites of various orthopaedic institutions. Each question was separately entered into ChatGPT (version 3.5), and responses were recorded, scored, and graded independently by 3 authors. The reading level of the ChatGPT response was calculated using the WordCalc software package, and readability was assessed using the Flesch-Kincaid grade level, Simple Measure of Gobbledygook index, Coleman-Liau index, Gunning fog index, and automated readability index.

RESULTS

Of the 10 frequently asked questions entered into ChatGPT, 6 were deemed as unsatisfactory and requiring substantial clarification; 1, as adequate and requiring moderate clarification; 1, as adequate and requiring minor clarification; and 2, as satisfactory and requiring minimal clarification. The mean DISCERN score was 41 (inter-rater reliability, 0.721), indicating the responses to the questions were average. According to the readability assessments, a full understanding of the ChatGPT responses required 13.4 years of education, which corresponds to the reading level of a college sophomore.

CONCLUSIONS

Most of the ChatGPT-generated responses were outdated and failed to provide an adequate foundation for patients' understanding regarding their injury and treatment options. The reading level required to understand the responses was too advanced for some patients, leading to potential misunderstanding and misinterpretation of information. ChatGPT lacks the ability to differentiate and prioritize information that is presented to patients.

CLINICAL RELEVANCE

Recognizing the shortcomings in artificial intelligence platforms may equip surgeons to better set expectations and provide support for patients considering and preparing for ACL reconstruction.

Operative treatment in non-emergency sports injuries: a sports medicine clinic experience

PURPOSE

To elucidate referrals from sports medicine clinic (SMC) to orthopedics, consensus rates among physicians and surgeons on surgical need in these patients, and reasoning of the patients who refused to have surgery despite the recommendations by both groups in non-emergency sports injury patients.

METHODS

We conducted a retrospective cohort analysis by using the administrative and referral records of a sports medicine clinic for the 15 months between October 2017 and January 2019. Gender, age, diagnosis, and type of sport were compared between two groups (patients referred to orthopedics vs patients treated in SMC). Agreement between orthopedics and SMC on surgical need in those patients who were referred to orthopedics was evaluated. We additionally screened the hospital archive for surgery reports of patients recommended surgery, and, if a patient did not have a surgery record, we investigated the reasons by telephone interview and categorized these reasons.

RESULTS

Surgical evaluation needed for 4.7% (n = 155) of the patients. Patients referred to orthopedics were younger (median: 22.0 years), mostly male (n = 119, 76.8%), and involved in contact sports (n = 108, 69.7%) (p < 0.001 for all) compared to patients treated conservatively. Majority of the consultations were made owing to certain diagnoses such as cruciate/collateral ligament sprain (n = 70, 45.2%), meniscal tear (n = 21, 13.5%), and cartilage injuries (n = 15, 9.7%). Most of the patients diagnosed with Achilles tendon rupture (n = 2, 100%) and patellar instability (n = 13, 81.3%) were referred to surgery. Orthopedics agreed with the sports medicine physicians' opinions in most cases (n = 110, 71.0%). Thirty-four patients (30.9%) recommended surgery by the surgeon postponed/refused the treatment for various reasons or had surgery in another hospital.

CONCLUSION

Most non-emergency sports injuries can be treated conservatively. Young and male patients participating in contact sports are more likely to need surgical treatment. Non-surgeon musculoskeletal health-care providers may consider referring patients to orthopedics considering the data demonstrated in this study. Nevertheless, patient's motivation to undergo an operation should be considered before referring to orthopedics.

Morphometric characteristics of the knee are associated with the injury of the meniscus

Background

To assess the geometrical risk factors for meniscal injuries. We hypothesized that the narrowness of the intercondylar notch and the smaller tibial spine could increase the risk of meniscal injuries.

Methods

We retrospectively studied two hundred and seven patients examined for knee magnetic resonance images. Two experienced orthopedists evaluated the severity of meniscal injuries. The notch width, bicondylar notch width, notch width index, condyle width of the femur, tibial spine height, and intercondylar angle were measured in magnetic resonance image slides by two blinded orthopedists.

Results

A total of 112 patients with a meniscus injury and 95 patients were as healthy control in all two hundred and seven patients. The NWI (P = 0.027) in patients with meniscus injuries was significantly different from the control group. A 1 SD (0.04 mm) increase in NWI was associated with a 0.4-fold increase in the risk of meniscal injury. A 1 SD (0.04 mm) increase in NWI was associated with a 0.64-fold increase in the risk of grade 3 meniscal injury. Furthermore, NWI and medial spine height are decreased significantly in grade 2 (P < 0.05) meniscal injury than in other grades. The medial spine height was significantly decreased in the meniscal injury group (P = 0.025), and the decrease in medial spine height would increase the risk of meniscal injury (OR = 0.77) and grade 3 meniscal injury (OR = 0.8).

Conclusions

The stenosis of the femoral intercondylar notch and small medial tibial spine is risk factors of meniscal injury. The decreased NWI and the medial tibial spine height were also associated with the severity of the meniscal injury.

Risk of surgery and epidemiological profile of athletes presenting to a single sports injury clinic in Hong Kong

Background

Although participation in sports and exercise is promoted widely due to its health benefits, sports-related injuries can also be a detriment to an individual's health and a burden for the healthcare system. Herein, the aim of this study is to provide a comprehensive review on the epidemiological profile and the risk for surgery of athletes presented to a sports injuries clinic in Hong Kong.

Methods

A total of 566 patients attending the sports injuries clinic at a local hospital between October 2017 and September 2018 were reviewed. Only 271 patients sustaining injuries from sports activities were included. These patients attended a survey-based data collection session, which recorded their demographic, injury site, events leading to injury, exercise details (type, level-of-play, frequency, experience), and functional score according to the injury site.

Results

The highest proportion of injuries was observed in amateur athletes (45.4%) than in recreational (28.8%) and professional (25.8%). Those patients aged between 18–29 years old (50.2%) had the most injuries. Both soccer (25.1%) and basketball (25.1%) were the two most common sports to incurred injuries. Whereas, the lower extremities being the most common injured sites. Based on our logistic model, athletes with less experience were more prone to required surgeries with injuries in the lower extremities.

Conclusion

Preventive measures should be targeted at less experience athletes, focusing on strengthening the knee region, to reduce sports-related injuries and surgeries. Importantly, this study demonstrates the need to further identify factors to develop effective sports injury prevention programmes for tailoring athletes at different levels-of-play.

Sex differences in the relationship of hip strength and functional performance to chronic ankle instability scores

Background

While decreased hip abductor strength, functional performance, and self-reported instability scores have all been shown in association with CAI, any sex difference in the relationship between these indicators is unclear. This study was to determine whether sex differences are present in the relationship between these indicators in individuals with CAI.

Methods

Thirty-two women and twenty-nine men with unilateral CAI took part. Hip abductor strength and functional performance were respectively assessed using a hand-held dynamometer and the figure-8-hop test. All 61 participants scored the Cumberland Ankle Instability Tool (CAIT) for self-reported ankle instability. Independent sample t-tests and correlation analysis were conducted.

Results

Normalized hip abductor strength and functional performance measures for females were lower than for males. The self-reported ankle instability CAIT score, where higher values represent less instability, was significantly and positively correlated with both normalized hip abductor strength (p = 0.003) and functional performance (p = 0.001) on the affected side in females, but not in males (p = 0.361 and p = 0.192 respectively).

Conclusions

Sex differences were observed in that there were significant relationships between normalized hip abductor strength, functional performance, and CAIT scores in female CAI participants, but not males, suggesting that CAI evaluation and rehabilitation strategies should be sex-specific.

Highlights

In females with CAI, hip abductor strength and functional performance showed significant relationships with self-reported instability scores.

Correspondingly, in clinical practice with individuals with CAI, evaluation criteria may be formulated according to these observed sex differences.

Sex differences should be factored into the evaluation and treatment of CAI individuals.

Hip strength assessment should be employed with CAI individuals.

Hip strengthening and functional hopping may be recommended for the rehabilitation of CAI, especially in female patients.

Limited medial osteochondral lesions of the talus associated with chronic ankle instability do not impact the results of endoscopic modified Broström ligament repair

Background

The arthroscopic modified Broström procedure, with repair of the anterior talofibular ligament and extensor retinaculum, produces good functional outcomes in patients with chronic lateral ankle instability (CLAI). CLAI can be associated with osteochondral lesions of the talus (OLTs). It remains unclear whether associated limited OLTs affect clinical outcomes in such patients.

Methods

This retrospective cohort study included 92 CLAI patients with and without OLTs undergoing an all-inside arthroscopic modified Broström procedure from June 2016 to May 2019. The patients were divided into non-lesion group (n = 32) and lesion group (n = 60) according to whether CLAI was associated or not with OLTs. All the osteochondral lesions less than 15 mm in diameter were managed with bone marrow stimulation techniques (arthroscopic microfracture) at the time of the arthroscopic modified Broström procedure. The Visual Analogue Scale (VAS) scores, American Orthopedic Foot and Ankle Society (AOFAS) scores, Karlsson Ankle Function Score (KAFS), Anterior Talar Translation (ATT), Active Joint Position Sense (AJPS), and the rate of return to sports were compared in both groups.

Results

Increase in all the functional scores (VAS, AOFAS, KAFS, ATT, and AJPS) in both groups was, respectively, recorded 1 year and 2 years after surgery. At the 1-year and 2-year follow-up, there was no significant difference in the VAS, AOFAS, KAFS, ATT, and AJPS scores between the non-lesion and lesion groups.

Conclusion

In patients with CLAI who underwent an arthroscopic modified Broström procedure, the presence of limited OLTs (less than 15 mm in diameter), which required arthroscopic microfracture, did not exert any influence on outcome.

Analysis of Medical Malpractice Outcomes for Sports Orthopedic Procedures

Orthopedic sports medicine surgeons are especially vulnerable to litigation, largely because of high patient expectations in the setting of complex surgeries. Understanding the factors associated with litigation may reduce physician risk as well as optimize patient satisfaction and outcomes. We used a national medicolegal database to search for medical malpractice verdicts and out-of-court settlements involving common sports injuries and their surgical management between January 1, 2000, and January 1, 2018. Univariate analysis was performed to identify predictors of case outcome and monetary awards. We identified 777 cases, but only 328 met the inclusion criteria. Of the 328 cases included in our study, 231 (70.4%) resulted in a defendant verdict, 75 (22.9%) resulted in a plaintiff verdict, and 22 (6.7%) resulted in a settlement. The most common reason for litigation was intraoperative error (183 cases, 55.8%). No statistically significant difference was found between monetary awards for plaintiff verdicts vs settlements (mean award of $1.29 million and $0.72 million, respectively, P=.07). Cases in which the plaintiff claimed neurovascular injury were significantly more likely to result in a higher monetary award (mean award of $2.37 million, P=.02). Cases involving an incorrect surgical site were significantly less likely to result in a defendant outcome, with 7 of 12 cases (58.3%) leading to a plaintiff outcome (P=.047). With more than two-thirds of cases resulting in a defendant verdict, many suits result in a favorable outcome for practitioners. Intraoperative error is the most common reason for litigation, and neurovascular injury resulted in the highest monetary payouts. Vigilance to avoid these events may improve patient outcomes and decrease liability to practitioners. [Orthopedics. 2022;45(1):e47-e52.].

Validation of Foot and Ankle Ability Measure (FAAM) and the Foot and Ankle Outcome Score (FAOS) in individuals with chronic ankle instability: a cross-sectional observational study

Background

Ankle sprain is the most common lower limb injury in physically active individuals. Loss of function, decreased postural control (PC), strength deficit, and reduced range of motion (ROM) are common after acute lateral ankle sprains. Some patients experienced long lasting symptoms, with recurrent sprains, and episodes of giving-way: a condition known as chronic ankle instability (CAI). Evaluating the function in patients with CAI in the clinical environment is important to identify the severity of the condition, in addition to allowing to assess the effectiveness of a given treatment. The aim of this study was to investigate the validation of the Foot and Ankle Ability Measure (FAAM) and the Foot and Ankle Outcome Score (FAOS) in terms of muscle strength, PC and ROM in adults with CAI.

Methods

This is a cross-sectional study. Individuals with CAI aged between 18 and 45 years were eligible. Individuals with CAI were identified using the Identification of Functional Ankle Instability (IdFAI). All patients filled in the FAAM and FAOS scores. Muscle strength was assessed by manual dynamometry, ROM by the Lunge test, PC by computerized posturography, modified Star Excursion Balance Test (mSEBT) and modified Balance Error Score System (mBESS).

Results

50 participants were enrolled in the present study. The mean age of the patients was 27.2 ± 6.3 years, and the mean body mass index was 26.4 ± 4.8 kg/m2. 58% (29 of 50) were men and 42% (21 of 50) women. 18 individuals had unilateral (36%) and 32 bilateral (64%) CAI. The results of FAAM were associated with MCT, mSEBT, invertor muscles strength, plantar flexor muscles strength, dorsiflexor muscles strength, and external hip rotator muscles strength (P < 0.05). The results of FAOS were associated with mSEBT, invertor muscles strength, plantar flexor muscles strength, dorsiflexor muscles strength, evertor muscles strength, and external hip rotator muscles strength, and mBEES (P < 0.05).

Conclusion

Both the FAAM and FAOS demonstrated validity to evaluate postural control and muscle strength in patients with CAI, while no association was found in relation to ankle dorsiflexion.

The Majority of Complaints About Orthopedic Sports Surgeons on Yelp Are Nonclinical

Purpose

To examine and characterize extremely negative Yelp reviews of orthopedic sports surgeons in the United States.

Methods

A search for reviews was performed using the keywords “Orthopedic Sports Medicine” on Yelp.com for 8 major metropolitan areas. Single-star reviews were isolated for analysis, and individual complaints were then categorized as clinical or nonclinical. The reviews were classified as surgical or nonsurgical.

Results

A total of 11,033 reviews were surveyed. Of these, 1,045 (9.5%) were identified as 1-star, and 289 were ultimately included in the study. These reviews encompassed 566 total complaints, 133 (23%) of which were clinical, and 433 (77%) of which were nonclinical in nature. The most common clinical complaints concerned complications (32 complaints; 6%), misdiagnosis (29 complaints; 5%), and uncontrolled pain (21 complaints; 4%). The most common nonclinical complaints concerned physicians’ bedside manner (120 complaints; 21%), unprofessional staff (98 complaints; 17%), and finances (78 complaints; 14%). Patients who had undergone surgery wrote 47 reviews that resulted in 114 complaints (20.5% of total complaints), whereas nonsurgical patients were responsible for 242 reviews and a total of 452 complaints (81.3% of total complaints). The difference in the number of complaints by patients after surgery and patients without surgery was statistically significant (P < 0.05) for all categories except for uncontrolled pain, delay in care, bedside manner of midlevel staff, and facilities.

Conclusion

Our study of extremely negative Yelp reviews found that 77% of negative complaints were nonclinical in nature. The most common clinical complaints were complications, misdiagnoses and uncontrolled pain. Only 16% of 1-star reviews were from surgical patients.

Clinical Relevance

Patients use online review platforms when choosing surgeons. A comprehensive understanding of factors affecting patient satisfaction and dissatisfaction is needed. The results of our study could be used to guide future quality-improvement measures and to assist surgeons in maintaining favorable online reputations.

The Quality and Content of Internet-Based Information on Orthopaedic Sports Medicine Requires Improvement: A Systematic Review

Purpose

To evaluate the quality and content of internet-based information available for some of the most common orthopaedic sports medicine terms.

Methods

A search of the PubMed, Embase, and Cochrane databases following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines was performed. All English-language literature published from 2010 to 2020 discussing information quality pertaining to orthopaedic sports medicine terms was included. Outcomes included the search engines used, number and type of websites evaluated, platform, and quality scoring metrics. Descriptive statistics are presented.

Results

This review includes 21 studies. Of these, 3 evaluated both the upper and lower extremity. Twelve focused on either the upper or lower extremity, most commonly rotator cuff tears (3 of 12) and/or anterior cruciate ligament pathologies (7 of 12). The most common engines were Google (18 of 21), Bing (16 of 21), Yahoo (16 of 21), YouTube (3 of 21), Ask (3 of 21), and AOL (2 of 21). The average number of media files assessed per study was 87 ± 55. Website quality was assessed with DISCERN (7 of 21), Flesch-Kincaid (9 of 21), Health on the Net (7 of 21), and/or Journal of the American Medical Association Benchmark (7 of 21) scores. YouTube was evaluated with Journal of the American Medical Association Benchmark scores (1.74 ± 1.00). Image quality was reported in 2 studies and varied with search terminology.

Conclusions

The results of this systematic review suggest that physicians should improve the quality of online information and encourage patients to access credible sources when conducting their own research.

Clinical Relevance

Doctors can and should play an active role in closing the gap between the level of health literacy of their patients and that of most common online resources.

Telemedicine as a Therapeutic Option in Sports Medicine: Results of a Nationwide Cross-Sectional Study among Physicians and Patients in Germany

Background: Worldwide, the number of treatments in the field of sports medicine is increasing. However, the COVID-19 pandemic has changed everyday life. Many consultations had to be cancelled, postponed, or converted to a virtual format. Telemedicine in sports medicine could support physicians. This study analyzes the use and perception of telemedicine applications among physicians and patients in the field of sports medicine in Germany. Methods: This prospective cross-sectional study was based on a survey of sports medicine physicians and patients in Germany during the COVID-19 pandemic. Descriptive statistics were calculated. Results: We analyzed the responses of 729 patients and 702 sports medicine physicians. Most believed that telemedicine is useful. Both physicians and patients rated their knowledge of telemedicine as unsatisfactory. The majority of respondents said they do not currently use telemedicine but would like to do so. Patients and physicians reported that their attitude had changed positively towards telemedicine and that their usage had increased due to COVID-19. The majority in both groups agreed on implementing virtual visits in stable disease conditions. Telemedicine was considered helpful for follow-up monitoring and prevention by both groups. Conclusion: Telemedicine in sports medicine has seen limited use but is highly accepted among physicians and patients alike. The absence of a structured framework is an obstacle to effective implementation. Training courses should be introduced to improve the limited knowledge regarding the use of telemedicine. More research in telemedicine in sports medicine is needed. This includes large-scale randomized controlled trials, economic analyses and explorations of user preferences.

Editorial Commentary: Preoperative Patient-Reported Outcomes Measurement Information System Scores Predict Which Patients Will Benefit From Arthroscopic Meniscectomy: To Scope or Not to Scope?

Despite its widespread use and low complication rates, arthroscopic meniscectomy has not been uniformly successful in all patients, especially in those with concurrent osteoarthritis. The Patient-Reported Outcomes Measurement Information System (PROMIS) is an initiative funded by the National Institutes of Health to develop and validate patient-reported outcomes for clinical research and practice. PROMIS has shown the ability to enhance and standardize measurement of a variety of health domains affecting musculoskeletal function and in discriminating between various orthopaedic procedures through the use of computer adaptive testing. Preoperative PROMIS scores are valid predictors of postoperative minimal clinically important difference in patients undergoing arthroscopic meniscectomy based on preoperative decreased physical function and increased pain interference. PROMIS score cutoffs may be used by arthroscopic surgeons to counsel patients considering arthroscopic meniscectomy.

All-inside arthroscopic modified Broström-Gould procedure for chronic lateral ankle instability with and without anterior talofibular ligament remnant repair produced similar functional results

PURPOSE

The Broström-Gould procedure, with the repair of the anterior talofibular ligament (ATFL) combined with the transfer of the extensor retinaculum, is considered the gold standard procedure for the management of chronic lateral ankle instability (CLAI). Lateral ligament reconstruction is considered if the ATFL remnant quality is poor or the ATFL has been damaged beyond the ability to suture it. It remains unclear whether not repairing the ATFL remnant produces comparable functional outcomes to the classical Broström-Gould procedure.

METHODS

This retrospective cohort study included 84 patients with CLAI undergoing either repair or non-repair of the ATFL remnant using an all-inside arthroscopic Broström-Gould procedure from 2015 to 2018. The Visual Analogue Scale (VAS) scores, American Orthopedic Foot and Ankle Society (AOFAS) scores, Karlsson Ankle Functional Score (KAFS), Anterior Talar Translation (ATT), Active Joint Position Sense (AJPS), and the rate of return to sports were compared in both groups.

RESULTS

All the functional scores (VAS, AOFAS, KAFS, ATT, AJPS) significantly improved in both groups at 1 and 2 years after surgery. At all the follow-up time points, the VAS, AOFAS, KAFS, ATT, AJPS, and the rate of return to sport scores were comparable between the repair and non-repair group.

CONCLUSION

There are no statistically significant differences in postoperative outcomes between ATFL remnant repair and non-repair for the management of CLAI using the all-inside arthroscopic Broström-Gould procedure. From the clinical viewpoint, the present study shows that the potential differences in clinical outcomes between ATFL remnant repair and non-repair are likely not relevant when performing an all-inside arthroscopic Broström-Gould procedure for CLAI.

Combined medial patellofemoral and patellotibial reconstruction with soft tissue fixation in recurrent patellar dislocation

INTRODUCTION

The medial patellofemoral and patellotibial ligaments (MPFL and MPTL) are the main passive restraints to lateral patellar translation. When nonoperative management of patellofemoral dislocations fails, surgical options can be considered to restore patellofemoral stability. Several reconstruction procedures of the MPFL with semitendinosus, gracilis, quadriceps tendon, and synthetic grafts have been described. No clear superiority of one surgical technique over another is evident.

MATERIALS AND METHODS

Patients who suffered at least two documented episodes of unilateral patellar dislocation, confirmed radiographically and at clinical examination, underwent combined MPFL and MPTL reconstruction. Patients were regularly followed-up postoperatively at 2, 4, 8, 12, and 24 weeks, and then annually for a minimum of 2.5 years. Clinical and functional evaluations were performed using the modified Cincinnati rating system and the Kujala score, while anthropometry values including thigh volume and cross-sectional area of the thigh were measured before the operation and at the latest follow-up bilaterally.

RESULTS

There were 7 males and 27 females with a mean age of 26.5 ± 10.7 years (range, 13-39 years). The mean follow-up was 3.1 years (range, 2.5-4 years). The mean modified Cincinnati score Increased from 51 ± 22 preoperatively to 90 ± 19 (P = .001). The mean Kujala scores increased from 47 ± 17 preoperatively to 82 ± 17 (P = .02), with no significant differences between patients with or without osteochondral lesions (P ≥ .05), and between male and female patients (P ≥ .08). The Insall-Salvati index was 1.1 preoperatively and remained within normal range (P = .05) at the latest follow-up.

CONCLUSION

Combined reconstruction of MPFL and MPTL using an ipsilateral autologous gracilis tendon is satisfactory and effective and can be considered as suitable management option to treat recurrent dislocation of the patella. However, randomized studies are needed to compare different techniques.

Use of the Patient-Reported Outcomes Measurement Information System (PROMIS) for Operative Shoulder Outcomes

Background:

Few studies have investigated the relationship between the Patient-Reported Outcomes Measurement Information System (PROMIS) and legacy patient-reported outcome (PRO) measurements.

Purpose:

To compare patient-reported outcomes from the PROMIS physical function (PF) and upper extremity (UE) platforms against one another and against legacy PRO measurements to assess the potential strengths and weaknesses of the National Institutes of Health PROMIS initiative and expand on the use of PRO measurements in clinical orthopaedic practice.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A systematic search of the PubMed, Embase, and Cochrane Library databases was conducted following PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines. All English-language studies published between 2017 and 2019 using PROMIS to evaluate patients for shoulder surgery were analyzed. PROs were compared based on survey administered and the shoulder condition being investigated. Study quality was evaluated using the Modified Coleman Methodology Score and the Methodological Index for Non-Randomized Studies score.

Results:

We included 9 studies (5 studies were level 2; 3 studies were level 3; 1 study was level 4) encompassing a total of 1130 patients (60.2% male; mean age, 52.6 ± 16.5 years; mean BMI, 29.8 ± 2.8 kg/m²). Of these, 6 studies administered the PROMIS PF, and 6 studies administered the PROMIS UE. The strongest correlation was between PROMIS PF computer adaptive test and the 36-Item Short Form Health Survey Global Health (SF-36 GH) (r = 0.75). The highest overall correlation with the PROMIS UE was found with the American Shoulder and Elbow Surgeons (ASES) Shoulder Score (r = 0.70). The lowest correlations were found between PROMIS PF and the Marx Shoulder Activity Scale (r = 0.08) and the PROMIS UE and the Marx Shoulder Activity Scale (r = 0.18).

Conclusion:

From available data, the PROMIS PF and PROMIS UE were most closely correlated with outcomes measured by the SF-36 GH. The PROMIS UE alone was most correlated with ASES Shoulder Score. Thus, either PROMIS PF or UE may provide a possible alternative to legacy PRO measurements but with a lower overall number of questions and higher generalizability. Future research should compare the time and question burden of the various PROMIS platforms with a more consistent evaluation of standard PRO measurements.

Neuroplasticity and Anterior Cruciate Ligament Injury

INTRODUCTION

Anterior cruciate ligament (ACL) tears are common, with a seemingly constant increase in their number, and potentially serious consequences for sports participation and long-term general and musculoskeletal health.

AREAS OF AGREEMENT

Most players are able to return to cutting sport after ACL reconstruction, but some sustain further knee problems needing different approach to their rehabilitation.

GROWING POINTS

Neurocognitive tasks, measuring reaction time, processing speed, visual memory and verbal memory, allow indirect assessment of cerebral performance. Situational awareness, arousal, and attentional resources may influence neurocognitive function, affecting the complex integration of vestibular, visual, and somatosensory information needed for neuromuscular control.

AREAS OF CONTROVERSY

The underlying reasons for uncoordinated, high-velocity movements observed during non-contact injuries of the knee producing an ACL tear are not well understood. Fundamental neuropsychological characteristics are responsible for situational awareness, sensory integration, motor planning, and coordination, all of which control joint stiffness. There is a strong link between acquisition of motor skills and neuronal plasticity at cortical and subcortical levels in the central nervous system; these links may evolve over time and engage different spatially distributed interconnected brain regions. A cascade of neurophysiological alterations occurs after ACL injury.

AREAS TIMELY FOR DEVELOPING RESEARCH

Training can improve function; hence, rehabilitation programmes which include perturbation training, agility training, vision training and sport-specific skill training are essential after ACL injuries and for injury prevention, and to optimize return to play.
