There is high variability in quantitative measurement techniques in glenohumeral capsular measurements for shoulder instability: A systematic review

PURPOSE

Instability of the glenohumeral joint remains a complex clinical issue with high rates of surgical failure and significant morbidity. Advances in specific radiologic measurements involving the glenoid and the humerus have provided insight into glenohumeral pathology, which can be corrected surgically towards improving patient outcomes. The contributions of capsular pathology to ongoing instability remain unclear. The purpose of this study is to provide a systematic review of existing glenohumeral capsular measurement techniques published in the last 15 years.

METHODS

A systematic review of multiple databases was performed following PRISMA guidelines for all primary research articles between 2008 and 2023 with quantitative measurements of the glenohumeral capsule in patients with instability, including anterior, posterior and multi-directional instability.

RESULTS

There were a total of 14 articles meeting the inclusion criteria. High variability in measurement methodology across studies was observed, including variable amounts of intra-articular contrast, heterogeneity among magnetic resonance sequence acquisitions, differences in measurements performed and the specific approach taken to compute each measurement.

CONCLUSION

There is a need for standardization of methods in the measurement of glenohumeral capsular pathology in the setting of glenohumeral instability to allow for cross-study analysis.

Clinical Outcomes in Prospective versus Retrospective Studies on Arthroscopic Bankart Repair: A Systematic Review

BACKGROUND

The majority of the current literature on arthroscopic Bankart repair is retrospective and discrepancies exist regarding clinical outcomes including recurrent instability and return to play amongst studies of different levels of evidence.

PURPOSE

The purpose of this study is to perform a systematic review of the literature to compare the outcomes of prospective and retrospective studies on arthroscopic Bankart repair.

METHODS

A search was performed using the PubMed/Medline database for all studies that reported clinical outcomes on Bankart repair for anterior shoulder instability. The search term "Bankart repair" with all results being analyzed via strict inclusion and exclusion criteria. Three independent investigators extracted data and scored each included study based on the 10 criteria of the Modified Coleman Methodology Score (CMS) out of 100. A chi-square test was performed to assess if recurrent instability, revision, return to play, and complications are independent of prospective and retrospective studies.

RESULTS

One hundred ninety-three studies were included in the analysis with 53 prospective studies and 140 retrospective in design. Encompassing a total of 13,979 patients and 14,019 surgical procedures for Bankart repair for shoulder instability. The rate of re-dislocation in the prospective studies was 8.0% vs. 5.9% in retrospective (p < 0.001). The rate of recurrent subluxation in the prospective studies was 3.4% vs. 2.4% in retrospective (p = 0.004). The rate of revision was higher in retrospective studies at 4.9% vs. 3.9% in prospective studies (p = 0.013) There was no significant difference in terms of overall rate to return to play in prospective and retrospective studies was 90% and 91%, respectively (p=0.548). The overall rate of complications in the prospective cohort was 0.27% and 0.78% in the retrospective studies (p = 0.002).

CONCLUSION

The overall rates of recurrent dislocations, subluxations are higher in prospective studies compared to retrospective studies. However, rates of revision were reportedly higher in retrospective studies. Complications after arthroscopic Bankart repair are rare in both prospective and retrospective studies, and there was no difference in rates of return to play.

Examining the Evidence Regarding Smoking and Patient Outcomes for Isolated Meniscus Pathology: A Comprehensive Systematic Review and Meta-Analysis

Smoking is a well-known cause of impairment in wound healing and postoperative outcomes; however, its effects on treating meniscus issues remain unclear. This study assesses the relationship between smoking and meniscus treatment outcomes. PubMed, Scopus, Cochrane, and CINAHL were searched from inception to 24 December 2023. Inclusion criteria encompassed studies examining smoking's impact on patient outcomes regarding meniscus pathology. A secondary PubMed search targeted randomized controlled trials (RCTs) in the top ten orthopedic journals focusing on meniscus pathology and smoking as a demographic variable. Meta-analysis of six studies (n = 528) assessed meniscus failure rate based on smoking status. Eighteen observational studies (n = 8353 patients; 53.25% male; mean age: 51.35 ± 11.53 years; follow-up: 184.11 ± 117.34 months) were analyzed, covering meniscus repair, meniscectomy, allograft transplant, conservative care, and arthroscopy. Results showed four studies (36.36%) linked smoking with worse meniscus repair outcomes, while seven studies (63.64%) did not find significant associations. Meta-analysis from six studies showed no significant impact of smoking on repair failure (p = 0.118). Regarding meniscectomy, one study (33.33%) identified a significant association with smoking, but two did not. Only one (3.8%) of the RCTs in leading orthopedic journals included smoking as a factor. The evidence on smoking's effect on meniscus treatment is mixed, necessitating further investigation.

Type V Superior-Labrum Anterior-Posterior (SLAP) Repair - A Systematic Review

BACKGROUND

The purpose of this study is to systematically review the evidence in the literature to ascertain the functional outcomes, recurrence rates, and subsequent revision rates following type V superior labrum anterior-posterior (SLAP) repair.

METHODS

Two independent reviewers performed a literature search based on PRISMA guidelines, utilizing the EMBASE, MEDLINE, and The Cochrane Library Databases. Studies were included if they had clinical outcomes on the patients undergoing type V SLAP repair. Statistical analysis was performed using SPSS (IBM, Armonk, NY, USA). A P value of < 0.05 was considered to be statistically significant.

RESULTS

Our review found 13 studies, including 451 shoulders meeting our inclusion criteria. The majority of patients were male (89.3%), with an average age of 25.9 years (range 15-58) and a mean follow-up of 53.8 months. The Rowe score was the most utilized functional outcome score, with a weighted mean of 88.5. Additionally, the mean Constant score was 91.0, the mean ASES score was 88.3, the mean SSV score was 85.5%, and the mean VAS pain score was 1.2. The overall rate of return to play was 84.8%, with 80.2% returning to the same level of play. The overall reoperation rate was 6.1%, with a recurrent dislocation rate of 8.2%. In the studies comparing type V SLAP and isolated Bankart repair, there were statistically insignificant differences in VAS pain scores (MD; 0.15, 95% CI, -0.13 to 0.44, I2 = 0%, p = 0.29) and recurrence rates (RR; 1.38, 95% CI, 0.88 to 2.15, I2 = 0%, p = 0.16).

CONCLUSION

Arthroscopic repair of type V SLAP tears results in excellent functional outcomes, with high return to play rates in athletes. There are low rates of reoperations and recurrent dislocations. Additionally, in comparison to an isolated Bankart repair, SLAP repair does not increase recurrence rates or postoperative pain.

Evaluation High-Quality of Information from ChatGPT (Artificial Intelligence-Large Language Model) Artificial Intelligence on Shoulder Stabilization Surgery

PURPOSE

To analyze the quality and readability of information regarding shoulder stabilization surgery available using an online AI software (ChatGPT), using standardized scoring systems, as well as to report on the given answers by the AI.

METHODS

An open AI model (ChatGPT) was used to answer 23 commonly asked questions from patients on shoulder stabilization surgery. These answers were evaluated for medical accuracy, quality, and readability using The JAMA Benchmark criteria, DISCERN score, Flesch-Kincaid Reading Ease Score (FRES) & Grade Level (FKGL).

RESULTS

The JAMA Benchmark criteria score was 0, which is the lowest score, indicating no reliable resources cited. The DISCERN score was 60, which is considered a good score. The areas that open AI model did not achieve full marks were also related to the lack of available source material used to compile the answers, and finally some shortcomings with information not fully supported by the literature. The FRES was 26.2, and the FKGL was considered to be that of a college graduate.

CONCLUSIONS

There was generally high quality in the answers given on questions relating to shoulder stabilization surgery, but there was a high reading level required to comprehend the information presented. However, it is unclear where the answers came from with no source material cited. It is important to note that the ChatGPT software repeatedly references the need to discuss these questions with an orthopaedic surgeon and the importance of shared discussion making, as well as compliance with surgeon treatment recommendations.

CLINICAL RELEVANCE

As shoulder instability is an injury that predominantly affects younger individuals who may use the Internet for information, this study shows what information patients may be getting online.

Similar outcomes between biceps tenodesis and SLAP repair for SLAP tears in younger patients - A meta-analysis

OBJECTIVES

The purpose of this study is to systematically review the comparative studies in the literature to ascertain if biceps tenodesis or superior-labrum anterior to posterior (SLAP) repair results in superior clinical outcomes in the treatment of type II SLAP tears in patients under 40.

METHODS

A systematic search of articles in Pubmed, EMBASE and The Cochrane Library databases was carried out according to the PRISMA guidelines. Cohort studies comparing biceps tenodesis to repair in type II SLAP tears in patients under 40 were included. Clinical outcomes were extracted including return to play, reoperations, ASES, and VAS for pain. All statistical analysis was performed using Review Manager. A p-value of <0.05 was considered to be statistically significant.

RESULTS

Five studies were included. Biceps tenodesis resulted in comparable rates of return to play compared to SLAP repair (78.5% vs 67.7%, p ​= ​0.33), and there was no significant difference in return to play in overhead athletes (83.6% vs 74%, p ​= ​0.82). There was no significant difference in ASES score (87.2 vs 86.2, p ​= ​0.27) or VAS score for pain (1.8 vs 2.1, p ​= ​0.48). There was no significant difference in re-operation rates (2.9% vs 10.8%, p ​= ​0.22).

CONCLUSION

This study found that biceps tenodesis has no significant difference in rates of return to play in athletes, as well as in functional outcome scores and rates of revision surgery in younger patients compared to SLAP repair.

Majority of Studies Show Similar Rates of Return to Play After Arthroscopic Bankart Repair or Latarjet Procedure: A Systematic Review

PURPOSE

To systematically review the current evidence in the literature to compare return to play following arthroscopic Bankart repair versus open Latarjet procedure for the treatment of anterior shoulder instability.

METHODS

A literature search was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Comparative studies reporting return to play following arthroscopic Bankart repair versus open Latarjet procedure were included. Return to play was compared, with all statistical analysis performed using Review Manager, Version 5.3.

RESULTS

Nine studies with 1,242 patients (mean age: 15-30 years) were included. The rate of return to play was 61% to 94.1% among those undergoing arthroscopic Bankart repair and 72% to 96.8% in those undergoing an open Latarjet procedure. Two studies (Bessiere et al. and Zimmerman et al.) found a significant difference in favor of the Latarjet procedure (P < .05 for both, I2 = 37%). The rate of return to play at preinjury level was 9% to 83.8% among those undergoing arthroscopic Bankart repair and 19.4% to 80.6% in those undergoing an open Latarjet procedure, with no study finding a significant difference (P > .05 for all, I2 = 0%). The mean time of return to play was 5.4 to 7.3 months among those undergoing arthroscopic Bankart repair and 5.5 to 6.2 months in those undergoing an open Latarjet procedure, with no study finding a significant difference (P > .05 for all, I2 = 39%).

CONCLUSIONS

Overall, the majority of studies showed no significant difference in rates of return to play or timing following arthroscopic Bankart repair or open Latarjet procedure. Furthermore, no study has found a significant difference in rate of return to play at pre-injury level, or rate of return to play among collision athletes.

Nonoperative Management, Repair, or Reconstruction of the Medial Collateral Ligament in Combined Anterior Cruciate and Medial Collateral Ligament Injuries-Which Is Best? A Systematic Review and Meta-analysis

BACKGROUND

Combined injury of the anterior cruciate ligament (ACL) and the medial collateral ligament (MCL) is a common injury pattern and accounts for 20% of all ligamentous knee injuries. Despite advancements in surgical technique, there is no up-to-date consensus regarding the superiority of nonoperative versus operative management in higher-grade MCL tears of combined ACL-MCL injuries.

PURPOSE

To interpret recent literature on treatment options and to provide an updated evidence-based approach for management of combined ACL-MCL knee injuries.

STUDY DESIGN

Systematic review and meta-analysis; Level of evidence, 4.

METHODS

We performed a systematic review on outcomes following treatment of concomitant ACL and MCL injuries. A computerized search was conducted in PubMed, Embase.com, and Scopus.com. Authors independently assessed eligible studies and screened titles and abstracts. Articles reporting on patients with concomitant ACL and MCL injuries with or without concomitant procedures were included. Data regarding study design, sample size, patient age and sex, length of follow-up, timing of surgery, indications, surgical methods, concomitant procedures, outcomes, and complications were recorded. Patient-reported outcomes (PROs) and functional outcomes, including Knee injury and Osteoarthritis Outcome Score, International Knee Documentation Committee scores, Lysholm and Tegner scores, and range of motion, were estimated via meta-analysis and compared statistically by surgical approach.

RESULTS

In total, 18 studies were included in the systematic review with level 1 to level 4 evidence, with a total of 1,534 cases, were included in the systematic review. Of these, 16 studies with sufficient statistical reporting including 997 cases with sufficient follow-up were included in meta-analysis. Three different approaches to combined ACL-MCL injuries were identified: ACL reconstruction with (1) nonoperative MCL, (2) MCL repair, and (3) MCL reconstruction. There was no statistical difference between nonoperative versus surgically managed MCL injuries for PROs, range of motion at final follow up, or quadriceps strength.

CONCLUSION

Reconstruction of combined injury in a delayed fashion facilitates return of range of motion and may allow time for low-grade MCL tears to heal. If residual valgus or anteromedial rotatory laxity remains after a period of rehabilitation, then concomitant surgical management of ACL and MCL injuries is warranted. Avulsion MCL injuries and Stener-type lesions may benefit from early repair techniques.

Complications following arthroscopic Bankart repair: a systematic review

BACKGROUND

Complications are rare after arthroscopic Bankart repair, and as a result, there is a lack of guidance over rates of complications that can be used to consent patients. The purpose of this study is to systematically review the literature to assess the complications after arthroscopic Bankart repair, other than recurrent instability.

METHODS

A literature search of MEDLINE, Embase, and the Cochrane Library was performed based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Clinical studies reporting on the complications after arthroscopic Bankart repair were included.

RESULTS

A total of 194 studies were included in the analysis, with 13,979 patients and 14,019 shoulders undergoing arthroscopic Bankart repair. The overall complication rate was 0.67%, with frozen shoulder being the most common complication occurring in 0.32%. Persistent pain occurred in 0.17%. The rates of nerve, hardware, and wound complications were 0.07%, 0.05%, and 0.03%, respectively.

CONCLUSION

The arthroscopic Bankart repair has a very low rate of complications. Frozen shoulder and persistent pain are the most frequently encountered complications.

Jones Fracture in the National Football League

Background: Jones fracture, or proximal fifth metatarsal fracture, is a common injury in National Football League (NFL)-caliber athletes. Combine draft performance can greatly impact the long-term success of these athletes, and substantial emphasis has been placed on early return to play (RTP) and the minimization of post-operative complications after Jones fracture in these athletes. To date, no study has specifically described the treatment and outcomes of this injury specifically in NFL-caliber players, considering factors relevant to this unique population. Thus, the purpose of this review is to delve into Jones fracture in NFL-caliber athletes, evaluating the diagnostic, treatment, and RTP considerations. Methods: We searched Medline (PubMed), Embase (Elsevier), Scopus (Elsevier), and SPORTDiscus (EBSCOhost) for the concept of Jones fractures in the NFL. Using the PRISMA guidelines, a team of three reviewers conducted abstract screenings, full-text screenings, and the extraction of studies describing Jones fractures specifically in the NFL. Results: Of the 1911 studies identified, 6 primary retrospective studies met the inclusion and exclusion criteria. The heterogeneity of the outcome reporting precluded a meta-analysis; thus, a qualitative review of manuscripts describing Jones fracture was carried out. Classification, diagnosis, and treatment considerations, RTP statistics and outcomes, and complications were discussed. Amongst the primary studies, there were 285 Jones fractures, all athletes were able to RTP, and the average time to RTP ranged from 6 weeks to 27 weeks. For complications, with operative treatment, the refracture rate ranged from 4 to 12%, and incomplete healing ranged from 7 to 50%. RTP was 15 weeks for refractures. There were no patient-reported outcomes. Conclusions: The vast majority of Zone 2/3 Jones fractures are treated with IM screw fixation with or without adjunctive orthobiologics, such as bone marrow aspirate concentrate, in NFL-caliber athletes. The six major series investigating outcomes after the operative treatment of Jones fractures in NFL players reveal very positive findings overall with regard to RTP, reoperation, and career continuation.

Analyzing the Quality, Reliability, and Educational Value of ACL Rehabilitation Exercises on TikTok: A Cross-Sectional Study

Background

Videos relating to rehabilitation exercises for common injuries relevant to younger populations such as anterior cruciate ligament (ACL) tear receive high view counts on social media platforms such as TikTok.

Purpose/Hypothesis

The purpose of this study was to analyze the quality, reliability, and educational value of TikTok videos among the patient population for ACL injury. It was hypothesized that TikTok videos related to ACL rehabilitation exercises would lack quality, reliability, and educational value.

Study Design

Cross-sectional study.

Methods

TikTok was queried for relevant videos using the hashtags "#ACLrehab" and "#ACLexercises." For each included video, the type of uploader (general user or health care professional) was identified. In addition, the number of views, likes, shares, comments, and favorites for each included video was recorded, and the content of each video was graded using the DISCERN (a well-validated informational analysis tool) and the ACL exercise education score (ACLEES - a custom-designed tool for the evaluation of ACL-related exercises).

Results

A total of 111 videos with 5,520,660 cumulative views were included; the median number of views per video was 9801.0 (interquartile range [IQR], 3583.0-28,000.0). Of these videos, 84 and 27 were created by the general public and health care professionals, respectively. The videos collectively received 335,577 likes, 2969 comments, 22,856 favorites, and 6142 shares, with a median of 439 (IQR, 111-1374), 10 (IQR, 2.5-25.5), 54 (IQR, 18-172.5), and 12 (IQR, 2-36), respectively. The tabulated scores for the DISCERN and ACLEES between general users and health care professionals were all statistically nonsignificant. Health care professionals had a higher percentage of videos with a "very poor" DISCERN score in comparison with the general public (66.67% vs 53.57%, respectively).

Conclusion

The overall educational value of the TikTok videos related to ACL rehabilitation exercises was very poor. Health care professionals should be aware of the broad distribution of ACL rehabilitation exercise videos that are accessible on TikTok and raise awareness of the deficiencies of the platform as a medium for educational medical-related information.

Early clinical and patient-reported outcomes for arthroscopic and mini-open superior capsular reconstruction are similar for irreparable rotator cuff tears

OBJECTIVES

The purpose of this study was to report and compare postoperative range of motion (ROM), patient-reported outcomes, and failure rates following superior capsular reconstruction (SCR) and to compare outcomes between arthroscopic and mini-open techniques.

METHODS

All SCR procedures utilising dermal allograft with a minimum of 6 months of follow-up at multiple institutions between November 2015 and October 2019 were retrospectively reviewed. Preoperative patient demographics, imaging measurements, surgical technique (arthroscopic versus mini-open), and outcomes including pain scores, conversion to reverse shoulder arthroplasty, subsequent surgery, and postoperative ROM were recorded. Outcomes for arthroscopic versus mini-open approaches were compared via t-test, Fisher's exact test, or chi square test, as appropriate, with differences of p ​< ​0.05 considered significant.

RESULTS

180 total patients were included, including 98 who underwent arthroscopic SCR and 82 who underwent mini-open SCR. Final follow-up was at a mean of 32 months (standard deviation = 11 months). SCR improved pain (visual analog scale ​= ​4.4 pre-operatively vs. 1.4 post-operatively, p ​< ​0.0001) and ROMin active forward flexion (136° pre-operatively vs. 150° post-operatively, p ​= ​0.0012). No difference in post-operative pain visual analog scores was found between mini-open and arthroscopic cohorts (1.3 vs. 1.6, p ​= ​0.3432) at a mean of 14 months post-operatively. At a mean of 32 months post-operatively, there were no differences in ASES, QuickDASH, SST, WORC, or SANE scores between open and arthroscopic cohorts. There was no difference in rates of failure between mini-open and arthroscopic cohorts (15.9% vs. 17.3%, p ​= ​0.789).

CONCLUSIONS

This study confirmed that SCR improves pain and ROM in the short term. Mini-open SCR appears to provide similar improvements in pain and ROM compared with arthroscopic SCR, as well as patient-reported outcomes at 3 years. No difference in failure rates was detected between the 2 procedures.

Injury prevention strategies at the 2019 FIFA Women's World Cup display a multifactorial approach and highlight subjective wellness measurements

OBJECTIVE

To report the injury prevention programs utilised by top-level female footballers competing internationally.

METHODS

An online survey was administered to physicians of the 24 competing national teams at the 2019 Federation Internationale de Football Association (FIFA) Women's World Cup. The survey included 4 sections regarding perceptions and practices concerning non-contact injuries: (1) risk factors, (2) screening tests and monitoring tools, (3) preventative strategies, and (4) reflection on their World Cup experience.

RESULTS

Following responses from 54% of teams, the most common injuries encountered included muscle strains, ankle sprains, and anterior cruciate ligament ruptures. The study also revealed the most important injury risk factors during the FIFA 2019 World Cup. Intrinsic risk factors include accumulated fatigue, previous injury, and strength endurance. Extrinsic risk factors include reduced recovery time between matches, congested match schedule, and the number of club team matches played. The 5 most used tests for risk factors were flexibility, joint mobility, fitness, balance, and strength. Monitoring tools commonly used were subjective wellness, heart rate, minutes/matches played, and daily medical screening. Specific strategies to limit the risk of an anterior cruciate ligament injury included the FIFA 11+ program and proprioception training.

CONCLUSION

The present study revealed multifactorial approaches to injury prevention strategies for women's national football teams at the FIFA 2019 World Cup. Challenges to injury prevention program implementation reflect time limitations, schedule uncertainties, and varying club team recommendations.

The Socioeconomic consequences of femoral shaft fracture for patients in Malawi

Background

Femoral shaft fractures are common in Malawi, with an annual incidence of 44 per 100,000 people. Inadequate treatment and delayed presentation often result in functional, biopsychosocial, and financial challenges for patients. The purpose of this study was to examine the socioeconomic consequences of femoral shaft fractures for patients in Malawi.

Methods

This study of 42 patients was part of a larger study that prospectively examined quality of life. Questionnaires were distributed to patients at 1-year follow-up following femoral shaft fracture treatment. Patients reported pre- and post-injury standard of living and financial well-being.

Results

Patients reported relatively high transportation costs to and from the hospital. One year after injury, 17 patients (40%) had not returned to work. Of the 25 (60%) who had returned, 5 (20%) changed jobs due to their injury, all reported decreased productivity. Household income decreased for 29% of patients. 20 (49%) of 41 patients reported food insecurity in the week prior to questionnaire completion. Many patients reported changing their residence, borrowing money, selling personal property, and unenrolling children from school due to financial hardship caused by their injury.

Conclusion

While the Malawian public healthcare system is free at the point of care, it lacks the financial risk protection that is essential to universal health coverage (UHC). In this study, we found that the indirect costs of care due to femoral shaft fractures had substantial socioeconomic consequences on the majority of patients and their families. Increased investment of financial and human capital should be made into capacity building and preventative measures to decrease the burden of injury, increase access to care, improve care delivery, and provide financial risk protection for patients with traumatic injuries in Malawi.

Clinical and Biomechanical Outcomes of Suture Button Fixation for Ligamentous Lisfranc Injury: A Systematic Review and Meta-analysis

Background

Flexible ligamentous fixation has increased in popularity for the treatment of ligamentous Lisfranc injury, but the optimal fixation strategy is unclear.

Purpose

To review the biomechanical, clinical, and radiographic results of ligamentous Lisfranc injuries treated with flexible fixation.

Study Design

Systematic review; Level of evidence, 4.

Methods

A systematic literature review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The PubMed/Medline and Google Scholar literature databases were queried for clinical and biomechanical (cadaveric) studies relating to flexible fixation of ligamentous Lisfranc injury. Outcomes of interest included patient-reported outcome scores, clinical/biomechanical results, radiographic alignment, and return to activity. Where appropriate, meta-analysis of the postoperative outcomes was performed.

Results

Of the 34 initial studies, 14 articles (243 feet) were included in the analysis. In the 11 clinical studies (216 patients), the mean postoperative American Orthopaedic Foot & Ankle Society score was 90.1 (n = 150; 6 studies) and the mean visual analog scale score was 1.5 (n = 137; 5 studies). The rate of return to activity was 100% (n = 35; 5 studies), and 100% of patients maintained radiographic alignment postoperatively (n = 62; 6 studies). No complications or subsequent hardware removals were reported. Of the 3 biomechanical studies (27 feet), 1 study found significantly greater change in diastasis under axial load between intact and postfixation ligaments with suture button versus screw fixation (+1.1 vs -0.1 mm; P < .05), another found no difference in the decrease in diastasis under axial load between the injured state and screw or suture button fixation (1.2 vs 1.0 mm; P = .5), and the third found no difference in displacement between intact and either screw or suture button fixation under either axial (intact vs screw: 1.0 vs 2.0 mm, P = .1; intact vs suture button: 0.6 vs 1.8 mm, P = .1) or abduction (intact vs screw: 1.5 vs 1.1 mm, P = .5; intact vs suture button: 1.3 vs 2.1 mm, P = .1) load.

Conclusion

Flexible fixation use in the treatment of ligamentous Lisfranc injury was found to have significant potential as a fixation option, as demonstrated by excellent clinical results. Biomechanical evidence was inconclusive but suggested a trend toward decreased diastasis in specimens fixed with screws compared with suture buttons.

Trends in the surgical treatment of posterior shoulder instability in the United States from 2016 to 2020

Background

The purpose of this study was to describe trends in the incidence of open versus arthroscopic management of posterior shoulder instability (PSI) as well as the patients undergoing these procedures in the United States over time.

Methods

The PearlDiver Patient Records Database was utilized for this study. Cases of PSI and surgery were identified via the appropriate ICD-10-CM and CPT codes. Linear regression and two-sample Student's t-test were used to analyze incidence rates, procedure type, number of instability events, and patient age.

Results

A total of 5655 patients were identified as having PSI, undergoing a total of 686 capsulorraphies. The incidence of PSI treated surgically increased across the years of the study at a rate of 0.0293 per 100,000 person-years with an incidence in 2019-2020 greater than in 2016-2018 (p = 0.0151). Patients undergoing arthroscopic capsulorrhaphy were on average younger than those undergoing open capsulorrhaphy (p = 0.0021). Patients experienced a higher number of posterior instability events before open surgery compared to arthroscopic (p = 0.0274).

Discussion

The incidence of surgical treatment of PSI in the United States is steadily rising, with greater than 90% of cases being treated arthroscopically. Those undergoing arthroscopic posterior stabilization are both younger and face fewer instability events prior to surgery.

Association Between Preoperative Multidimensional Psychological Distress and Physical Function After Surgery for Sports-Related Injury

Background

Psychological distress after orthopaedic surgery can lead to worse outcomes, including higher levels of disability and pain and lower quality of life. The 10-item Optimal Screening for Prediction for Referral and Outcome-Yellow Flag (OSPRO-YF) survey screens for multiple psychological constructs relevant to recovery from orthopaedic injury and may be useful to preoperatively identify patients who may require further psychological assessment and possible intervention after surgery.

Purpose/Hypothesis

To determine the association between the OSPRO-YF and physiological patient-reported outcomes (PROs). It was hypothesized that higher OSPRO-YF scores (indicating worse psychological distress) would be associated with worse PRO scores at time of return to sport.

Study Design

Case series; Level of evidence, 4.

Methods

This study evaluated 107 patients at a single, academic health center who were assessed at a sports orthopaedics clinic and ultimately treated surgically for injuries to the knee, shoulder, foot, or ankle. Preoperatively, patients completed the OSPRO-YF survey as well as the following PRO measures: Patient-Reported Outcomes Measurement Information System (PROMIS), Single Assessment Numeric Evaluation, numeric rating scale for pain; American Shoulder and Elbow Surgeons standardized shoulder assessment form for patients with shoulder injuries, the International Knee Documentation Committee score (for patients with knee injuries), and the Foot and Ankle Ability Measure (FAAM; for patients with foot or ankle injuries). At the time of anticipated full recovery and/or return to sport, patients again completed the same PRO surveys. Multivariable regression was used to evaluate the association between total OSPRO-YF score at baseline and PRO scores at the time of functional recovery.

Results

The baseline OSPRO-YF score predicted postoperative PROMIS Physical Function and FAAM Sports scores only. A 1-unit increase in the OSPRO-YF was associated with a 0.55-point reduction in PROMIS Physical Function (95% CI, -1.05 to -0.04; P = .033) indicating worse outcomes. Among patients who underwent ankle surgery, a 1-unit increase in OSPRO-YF was associated with a 6.45-point reduction in FAAM Sports (95% CI, -12.0 to -0.87; P = .023).

Conclusion

The study findings demonstrated that the OSPRO-YF survey predicts certain long-term PRO scores at the time of expected return to sport, independent of baseline scores.

Distal Clavicle Autograft Versus Traditional and Congruent Arc Latarjet Procedures: A Comparison of Surface Area and Glenoid Apposition With 3-Dimensional Computed Tomography and 3-Dimensional Magnetic Resonance Imaging

BACKGROUND

Limited studies have compared graft-glenoid apposition and glenoid augmentation area between the Latarjet procedure and distal clavicle graft in glenohumeral stabilization. Additionally, preoperative planning is typically performed using computed tomography (CT), and few studies have used 3-dimensional (3D) magnetic resonance imaging (MRI) reformations to assess graft dimensions.

PURPOSE

The purpose of this study was 2-fold: (1) to compare bony apposition, glenoid augmentation, and graft width among coracoid and distal clavicle bony augmentation techniques and (2) to determine the viability of 3D MRI to assess bone graft dimensions.

STUDY DESIGN

Controlled laboratory study.

METHODS

A total of 24 patients with recurrent glenohumeral instability and bone loss were included in this study. 3D CT and 3D MRI reformations were utilized to measure pertinent dimensions for 5 orientations of coracoid and distal clavicle autografts: (1) standard Latarjet procedure (SLJ), (2) congruent arc Latarjet procedure (CLJ), (3) distal clavicle attached by its posterior surface (DCP), (4) distal clavicle attached by its inferior surface (DCI), and (5) distal clavicle attached by its resected end (DCR). Glenoid augmentation was defined as the graft surface area contributing to the glenoid. Bone-on-bone apposition was defined as the graft-glenoid contact area for bone healing potential, and graft width was pertinent for fixation technique. Glenoid bone loss ranged from 0% to 34%. Paired t tests were used to compare graft sizes between patients and compare 3D CT versus 3D MRI measurements.

RESULTS

The CLJ had the largest graft surface area (mean, 318.41 ± 74.44 mm²), while the SLJ displayed the most bone-on-bone apposition (mean, 318.41 ± 74.44 mm²). The DCI had the largest graft width (mean, 20.62 ± 3.93 mm). Paired t tests revealed no significant differences between the Latarjet techniques, whereas distal clavicle grafts varied significantly with orientation. All 3D CT and 3D MRI measurements were within 1 mm of each other, and only 2 demonstrated a statistically significant difference (coracoid width: 13.03 vs 13.98 mm, respectively [P = .010]; distal clavicle thickness: 9.69 vs 10.77 mm, respectively [P = .002]). 3D CT and 3D MRI measurements demonstrated a strong positive correlation (r > 0.6 and P < .001 for all dimensions).

CONCLUSION

Glenoid augmentation, bony apposition, and graft width varied with coracoid or distal clavicle graft type and orientation. Differences between 3D CT and 3D MRI were small and likely not clinically significant.

CLINICAL RELEVANCE

3D MRI is a viable method for preoperative planning and graft selection in glenoid bone loss.

Operative Versus Nonoperative Treatment of Acute Achilles Tendon Rupture: A Propensity Score-Matched Analysis of a Large National Dataset

Background

No consensus exists regarding the superiority of operative versus nonoperative management for Achilles tendon ruptures, as multiple randomized controlled trials conducted since the advent of early mobilization protocols have found outcomes for these 2 interventions to be more similar than were previously held.

Purpose

To use a large national database to (1) compare reoperation and complication rates between operative and nonoperative treatment of acute Achilles tendon ruptures and (2) evaluate trends in treatment and cost over time.

Study Design

Cohort study; Level of evidence, 3.

Methods

The MarketScan Commercial Claims and Encounters database was used to identify an unmatched cohort of 31,515 patients who sustained primary Achilles tendon ruptures between 2007 and 2015. Patients were stratified into operative and nonoperative treatment groups, and a propensity score-a matching algorithm-was used to establish a matched cohort of 17,996 patients (n = 8993 per treatment group). Reoperation rates, complications, and aggregate treatment costs were compared between groups with an alpha level of .05. A number needed to harm (NNH) was calculated from the absolute risk difference in complications between cohorts.

Results

The operative cohort experienced a significantly larger total number of complications within 30 days of injury (1026 vs 917; P = .0088). The absolute increase in cumulative risk was 1.2% with operative treatment, which resulted in an NNH of 83. Neither 1-year (1.1% [operative] vs 1.3% [nonoperative]; P = .1201) nor 2-year reoperation rates (1.9% [operative] vs 2% [nonoperative]; P = .2810) were significantly different. Operative care was more expensive than nonoperative care at 9 months and 2 years after injury; however, there was no difference in cost between treatments at 5 years. Before matching, the rate of surgical repair for Achilles tendon rupture remained stable, from 69.7% to 71.7% between 2007 and 2015, indicating little change in practice in the United States.

Conclusion

Results indicated no differences in reoperation rates between operative and nonoperative management of Achilles tendon ruptures. Operative management was associated with an increased risk of complications and higher initial costs, which dissipated over time. Between 2007 and 2015 the proportion of Achilles tendon ruptures managed operatively remained similar despite increasing evidence that nonoperative management of Achilles tendon rupture may provide equivalent outcomes.

Perioperative Management in the Collegiate Athlete: An Integrated Approach

Collegiate athletes face rigorous physical, academic, and emotional demands. While significant attention has been paid to injury prevention among young athletes in the past two decades, orthopedic injury rates remain high among collegiate athletes, and a significant number will undergo surgical management for injuries each year. In this narrative review, we describe techniques for perioperative management of pain and stress after surgery in collegiate athletes. In particular, we outline pharmacologic and non-pharmacologic management of surgical pain, with a goal of minimizing opiate consumption. We emphasize a multi-disciplinary approach to optimizing post-operative recovery in collegiate athletes help minimize reliance on opiate pain medication. Additionally, we recommend that institutional resources should be harnessed to support athletes in their well-being, from a nutritional, psychological and sleep standpoint. Critical to success in perioperative pain management is the communication among the athletic medicine team members and with the athlete and family to address pain and stress management and encourage timely, safe return to play.

Physeal Sparing Medial Patellofemoral Ligament Reconstruction With Suture Anchor for Femoral Fixation of Graft

Background:

Patellar instability is a common problem in the active pediatric population. Physeal sparing medial patellofemoral ligament (MPFL) reconstruction using a soft suture anchor for femoral graft fixation has the proposed advantages of diminishing volumetric bony removal from the epiphysis, increasing the margin of safety with respect to notch, trochlear, and/or physeal damage, as well as reducing the risk of thermal damage to the physis during socket reaming.

Indications:

MPFL reconstruction is indicated in patients with recurrent patellar instability with MPFL tear or attenuation on magnetic resonance imaging or failure of conservative treatment. Physeal sparing techniques are necessary in the pediatric population to prevent growth disturbance and deformities that can lead to significant long-term disability.

Technique Description:

The patient was placed in supine position. Following examination under anesthesia, diagnostic arthroscopy was performed to assess for patellofemoral chondral defects. The surgical technique required 6 steps: (1) medial patellar dissection, (2) patellar anchor placement with 1.8-mm suture anchors, (3) medial femoral dissection over Schottle’s point, (4) femoral anchor placement using 2.8-mm double loaded anchor, (5) allograft femoral fixation, and (6) allograft patellar fixation. After skin closure, examination under anesthesia was repeated.

Results:

The patient was weight-bearing as tolerated immediately after surgery, using a brace for the first 6 weeks. Rehabilitation progressed from regaining range of motion, strengthening of the operative extremity, and returning to sport activities. In the senior author’s experience using this technique, there have been no recurrent patellar dislocations and no evidence of growth disturbance or angulation. One patient did find that the graft was prominent over the femoral epicondyle and returned to the operating room for debulking at 9 months postoperatively.

Discussion/Conclusion:

In conclusion, we propose that physeal sparing MPFL reconstruction using soft anchors for patellar and femoral fixation offers a simple and safe technique with reproducible anatomic graft placement and favorable clinical outcomes. This technique is technically simple and can be easily learned by surgeons familiar with adult MPFL reconstruction techniques.

Telehealth Physical Therapy for Sports Medicine Rehabilitation: What Is Its Role in the Postpandemic Era?

BACKGROUND

The adoption of telehealth visits for physical therapy (PT) has accelerated because of the COVID-19 pandemic. Patient reception of virtual PT at the outbreak of the pandemic was positive, but it is unclear how telehealth visits compare to in-person visits in the postpandemic era.

PURPOSE

To evaluate utilization trends and patient satisfaction with virtual PT compared with in-person PT during and after the COVID-19 pandemic.

STUDY DESIGN

Cross-sectional study; Level of evidence, 3.

METHODS

We identified 59,461 in-person and 2016 telehealth visits at a single physical rehabilitation center between March 2020 and December 2021. Patient socioeconomic and demographic variables, including insurance status, were compared between telehealth users and in-person visitors. A total of 1012 patient satisfaction surveys were available and analyzed using the top-box method. Univariable statistics (t test or Mann-Whitney U and chi-square tests) were used for group comparisons.

RESULTS

Overall, telehealth users when compared with in-person visitors were older (median age, 47 vs 42 years, respectively; P < .001), and a higher proportion was female (60.6% vs 54.8%; P < .001), was White (69.7% vs 66.6%; P = .023), spoke English as their primary language (99.2% vs 98.1%; P = .001), and had Medicare insurance (20.3% vs 16.1%; P < .001). Telehealth patients more often lived out-of-county (50.7% vs 45.8%; P < .001) and in small towns rather than in urban areas (1.0% vs 0.3%; P < .001). When we compared telehealth use before and after official reopening of the PT center in September 2020, telehealth users in the postpandemic era had an out-of-county rate of 58.7%, and 68.7% were female. Patient satisfaction survey results demonstrated that telehealth patients compared with in-person patients were less likely to recommend visits to others (75.0% vs 89.1%, respectively; P = .008) and had lower overall assessment of their visits (71.7% vs 88.6%; P = .001). Accordingly, there was a significant reduction in telehealth visits from 2020 to 2021 (from 6.9% to 0.9% of visits; P < .001).

CONCLUSION

We noted a decline in telehealth PT use during the postpandemic era, consistent with reduced patient satisfaction when compared with in-person visits. Telehealth is a useful option for populations with limited time or access to care and may serve a role in a hybrid care model. Further studies on long-term outcomes after telehealth PT are warranted to evaluate its efficacy.

Single-Stage Surgical Treatment of Multi-ligament Knee Injuries Results in Lower Cost and Fewer Complications and Unplanned Reoperations Compared With Staged Treatment

Purpose

To compare complications, unplanned reoperations, and costs between single-stage and 2-stage treatment of multi-ligament knee injuries.

Methods

The MarketScan database was queried (2007-2016), identifying patients undergoing surgery for a multi-ligament knee injury. The single-stage cohort was defined as having at least 2 Current Procedural Terminology codes for ligament reconstruction at the index procedure without a Current Procedural Terminology code for ligament reconstruction appearing in the database for the following 12 months. The 2-stage cohort was defined as undergoing multiple ligament reconstruction procedures within a 12-month period with subsequent ligament procedure codes that differed from the index ligament reconstruction codes. Propensity score matching was performed using a greedy nearest-neighbor algorithm to match specific injury patterns between the 2 cohorts. Baseline demographic characteristics, medical comorbidities, and the Charlson Comorbidity Index were recorded. Complications, unplanned reoperations, and total health care expenditures were recorded for up to 5-year follow-up. Two-sample t tests, χ² tests, and Fisher exact tests were used with an α level of .05 set as significant.

Results

We identified 1,150 patients who underwent surgery for multi-ligament knee injuries (1,080 with single-stage approach and 270 with 2-stage approach). No significant differences in baseline characteristics or medical comorbidities were found between the cohorts. After propensity score matching, the single-stage group had fewer complications at 30, 90, 180, and 365 days (P < .05). Two-stage treatment increased the risk of reoperation at 1 year (5.5 times) and 2 years (4.9 times) after the index procedure. Health care expenditures were lower in the first 9 months for the staged cohort, but from 9 months ($31,210 vs $22,252, P < .0001) through 5 years, total costs were higher in this group.

Conclusions

Single-stage surgical treatment of multi-ligament knee injuries results in fewer complications and reoperations and lower total costs compared with 2-stage treatment, even after controlling for the number and combination of ligaments injured.

Short-term outcomes following dehydrated micronized allogenic cartilage versus isolated microfracture for treatment of medial talar osteochondral lesions

BACKGROUND

Osteochondral lesions of the talus (OLTs) have been traditionally treated with bone marrow stimulation techniques such as microfracture. However, conventional microfracture results in a biomechanically weaker repair tissue of predominantly type I collagen. Acellular micronized cartilage matrix (MCM) serves as a bioactive scaffold to restore hyaline cartilage. The purpose was to compare short-term outcomes after microfracture with and without augmentation with MCM for medial-sided OLTs.

METHODS

A retrospective review was performed between 2010-2019 for medial-sided OLTs undergoing treatment with either microfracture augmented with MCM or isolated microfracture. The MCM was hydrated with either bone marrow aspirate concentrate (BMAC) or platelet-rich plasma (PRP). Outcomes included visual analogue scale (VAS) pain scores, Foot and Ankle Activity Measure (FAAM) scores, return-to-daily activities, and return-to-sport.

RESULTS

48 patients (14 MCM with PRP, 6 MCM with BMAC; 28 isolated microfracture) with average age 35.5 years (range: 13.8-67.2 years) and mean follow-up 4.0 ± 3.4 years (range,.13-10.7) were included. There was no difference in average lesion size between MCM and microfracture groups (64.0 ± 49.4 mm² versus 57.3 ± 44.2 mm², P = .63) and a trend toward larger lesion size for BMAC compared to PRP (106.5 ± 59.2 versus 45.9 ± 32.1 mm², P = .056). There was no difference in time to return-to-activity (83.5 ± 18.8 versus 87.3 ± 49.1 days) or return-to-sports (151.9 ± 62.2 versus 165 ± 99.2 days) with MCM versus isolated microfracture. However, the MCM group had a significantly greater improvement in VAS pain score at final follow-up (4.9 ± 2.2 versus 2.7 ± 2.6, P = .0032) and significantly higher post-operative FAAM-Activities of Daily Living subscale scores (97.2 ± 8.2 versus 79.7 ± 32.8, P = .033).

CONCLUSIONS

Augmenting microfracture with MCM hydrated with PRP or BMAC may result in beneficial changes in pain scores and activities of daily living, but similar return-to-activities and return-to-sport times compared to microfracture alone in management of medial OLT.

MOntelukast as a potential CHondroprotective treatment following Anterior cruciate ligament reconstruction (MOCHA Trial): study protocol for a double-blind, randomized, placebo-controlled clinical trial

BACKGROUND

After anterior cruciate ligament (ACL) reconstruction, patient-reported outcomes are improved 10 years post-surgery; however, cytokine concentrations remain elevated years after surgery with over 80% of those with combined ACL and meniscus injuries having posttraumatic osteoarthritis (PTOA) within 10-15 years. The purpose of this multicenter, randomized, placebo-controlled trial is to assess whether a 6-month course of oral montelukast after ACL reconstruction reduces systemic markers of inflammation and biochemical and imaging biomarkers of cartilage degradation.

METHODS

We will enroll 30 individuals undergoing primary ACL reconstruction to participate in this IRB-approved multicenter clinical trial. This trial will target those at greatest risk of a more rapid PTOA onset (age range 25-50 with concomitant meniscus injury). Patients will be randomly assigned to a group instructed to take 10 mg of montelukast daily for 6 months following ACL reconstruction or placebo. Patients will be assessed prior to surgery and 1, 6, and 12 months following surgery. To determine if montelukast alters systemic inflammation following surgery, we will compare systemic concentrations of prostaglandin E2, monocyte chemoattractant protein-1, and pro-inflammatory cytokines between groups. We will also compare degradative changes on magnetic resonance imaging (MRI) collected 1 and 12 months following surgery between groups with reductions in early biomarkers of cartilage degradation assessed with urinary biomarkers of type II collagen breakdown and bony remodeling.

DISCUSSION

There is a complex interplay between the pro-inflammatory intra-articular environment, underlying bone remodeling, and progressive cartilage degradation. PTOA affects multiple tissues and appears to be more similar to rheumatoid arthritis than osteoarthritis with respect to inflammation. There is currently no treatment to delay or prevent PTOA after ACL injury. Since there is a larger and more persistent inflammatory response after ACL reconstruction than the initial insult of injury, treatment may need to be initiated after surgery, sustained over a period of time, and target multiple mechanisms in order to successfully alter the disease process. This study will assess whether a 6-month postoperative course of oral montelukast affects multiple PTOA mechanisms. Because montelukast administration can be safely sustained for long durations and offers a low-cost treatment option, should it be proven effective in the current trial, these results can be immediately incorporated into clinical practice.

Return to Sport After Shoulder Stabilization Procedures: A Criteria-Based Testing Continuum to Guide Rehabilitation and Inform Return-to-Play Decision Making

The athlete with shoulder instability poses a unique challenge to the sports medicine team. Clinical studies support surgical intervention followed by a phased approach to rehabilitation. In the latter phases, it is important to tailor this program to the individual’s specific athletic needs, which requires ongoing qualitative assessment and objective measurement. Passing a return-to-sport testing battery has been shown to decrease the risk of recurrent instability. What is lacking in the literature is a consensus for how to best measure shoulder performance when the required athletic demands are widely varied by hand dominance, sport played, and playing position. Multiple upper-extremity tests have been described in the literature, but there is no consensus on which tests should be used to direct rehabilitation and to safely return the athlete to unrestricted athletic exposure. Using available evidence, we suggest a framework for return-to-play testing that integrates traditional rehabilitation phases with performance testing and graduated sports exposure.

Immune cell profiles in synovial fluid after anterior cruciate ligament and meniscus injuries

Background

Anterior cruciate ligament (ACL) and meniscus tears are common knee injuries. Despite the high rate of post-traumatic osteoarthritis (PTOA) following these injuries, the contributing factors remain unclear. In this study, we characterized the immune cell profiles of normal and injured joints at the time of ACL and meniscal surgeries.

Methods

Twenty-nine patients (14 meniscus-injured and 15 ACL-injured) undergoing ACL and/or meniscus surgery but with a normal contralateral knee were recruited. During surgery, synovial fluid was aspirated from both normal and injured knees. Synovial fluid cells were pelleted, washed, and stained with an antibody cocktail consisting of fluorescent antibodies for cell surface proteins. Analysis of immune cells in the synovial fluid was performed by polychromatic flow cytometry. A broad spectrum immune cell panel was used in the first 10 subjects. Based on these results, a T cell-specific panel was used in the subsequent 19 subjects.

Results

Using the broad spectrum immune cell panel, we detected significantly more total viable cells and CD3 T cells in the injured compared to the paired normal knees. In addition, there were significantly more injured knees with T cells above a 500-cell threshold. Within the injured knees, CD4 and CD8 T cells were able to be differentiated into subsets. The frequency of total CD4 T cells was significantly different among injury types, but no statistical differences were detected among CD4 and CD8 T cell subsets by injury type.

Conclusions

Our findings provide foundational data showing that ACL and meniscus injuries induce an immune cell-rich microenvironment that consists primarily of T cells with multiple T helper phenotypes. Future studies investigating the relationship between immune cells and joint degeneration may provide an enhanced understanding of the pathophysiology of PTOA following joint injury.

Endoscopic Proximal Hamstring Repair Is Safe and Efficacious With High Patient Satisfaction at a Minimum of 2-Year Follow-Up

PURPOSE

To evaluate the short-term outcomes of endoscopic proximal hamstring repair including clinical outcomes, patient-reported outcomes, and complications.

METHODS

A retrospective analysis was performed on consecutive patients who underwent endoscopic proximal hamstring repair from 2013-2018 by a senior sports medicine orthopaedic surgeon. Demographic, operative, clinical data, complications, and patient-reported outcomes were collected and analyzed including the International Hip Outcome Tool-12 (iHOT-12), Single Assessment Numeric Evaluation (SANE), modified Harris Hip Score (mHHS), and the Hip Outcome Score activities of daily living scale (HOS-ADL).

RESULTS

Thirty patients were included with a minimum 24.0- and average 44.0-month follow-up. The average age was 52.0 years (standard deviation [SD], 14.2), and 80.0% (n = 24) were women. Most patients presented with a history of refractory insertional tendinosis (83.3%, n = 25) and an average of 34.0 months of symptoms prior to surgical intervention. Two-year patient-reported outcomes were clinically acceptable with a postoperative iHOT-12 of 81.9 (SD, 21.1), SANE 78.8% (SD, 20.0), mHHS 89.6 (SD 13.4), and HOS-ADLs 87.2% function (SD, 15.9). Nine patients (30%) had available preoperative iHOT-12 scores. Among these patients, the mean increase in iHOT-12 was 46.3 (P = .0005; n = 9). Eighty percent (n = 24) of patients achieved the iHOT-12 patient acceptability symptomatic state. Complications (3%) included 1 atraumatic rerupture. Four patients participated in an organized sport and 18 in recreational sport with a return to play of 100% and 72.2%, respectively. All patients returned to work. Some 76.7% (n = 23) of patients reported return to their baseline level of physical activity, and 73.3% (n=22) of patients reported complete resolution of pain at last follow-up. There was a 90.0% (n=27) satisfaction rate.

CONCLUSIONS

Short-term follow-up for endoscopic proximal hamstring repair shows high patient satisfaction (90.0%) and clinically significant patient-reported outcomes with minimal residual pain and a low complication rate (3%).

Cost utility analysis of intramedullary nailing and skeletal traction treatment for patients with femoral shaft fractures in Malawi

Background and purpose - In Malawi, both skeletal traction (ST) and intramedullary nailing (IMN) are used in the treatment of femoral shaft fractures, ST being the mainstay treatment. Previous studies have found that IMN has improved outcomes and is less expensive than ST. However, no cost-effectiveness analyses have yet compared IMN and ST in Malawi. We report the results of a cost-utility analysis (CUA) comparing treatment using either IMN or ST.Patients and methods - This was an economic evaluation study, where a CUA was done using a decision-tree model from the government healthcare payer and societal perspectives with an 1-year time horizon. We obtained EQ-5D-3L utility scores and probabilities from a prospective observational study assessing quality of life and function in 187 adult patients with femoral shaft fractures treated with either IMN or ST. The patients were followed up at 6 weeks, and 3, 6, and 12 months post-injury. Quality adjusted life years (QALYs) were calculated from utility scores using the area under the curve method. Direct treatment costs were obtained from a prospective micro costing study. Indirect costs included patient lost productivity, patient transportation, meals, and childcare costs associated with hospital stay and follow-up visits. Multiple sensitivity analyses assessed model uncertainty.Results - Total treatment costs were higher for ST ($1,349) compared with IMN ($1,122). QALYs were lower for ST than IMN, 0.71 (95% confidence interval [CI] 0.66-0.76) and 0.77 (CI 0.71-0.82) respectively. Based on lower cost and higher utility, IMN was the dominant strategy. IMN remained dominant in 94% of simulations. IMN would be less cost-effective than ST at a total procedure cost exceeding $880 from the payer's perspective, or $1,035 from the societal perspective.Interpretation - IMN was cost saving and more effective than ST in the treatment of adult femoral shaft fractures in Malawi, and may be an efficient use of limited healthcare resources.

Osteochondral Lesions of the Distal Tibial Plafond: A Systematic Review of Lesion Locations and Treatment Outcomes

BACKGROUND

Osteochondral lesions of the tibial plafond (OLTPs) remain less common than osteochondral lesions of the talus (OLTs), but recognition of the condition has increased.

PURPOSE

To systematically evaluate the literature on lesion locations and treatment outcomes of OLTPs, whether in isolation or in combination with OLTs.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

A search was performed using the PubMed, Embase, and CINAHL databases for studies on lesion locations or with imaging or treatment outcomes of OLTPs. Case reports and reports based on expert opinion were excluded. Lesion locations as well as outcome measure results were aggregated. The Methodological Index for Non-randomized Studies score was used to assess methodological quality when applicable.

RESULTS

Included in this review were 10 articles, all published in 2000 or later. Most studies were evidence level 4, and the mean Methodological Index for Non-randomized Studies score was 8.6 (range, 8-10). Overall, 174 confirmed OLTP cases were identified, and the mean patient age was 38.8 years. Of the 157 lesions with confirmed locations, the most common was central-medial (32/157; 20.4%). Of 6 studies on treatment outcomes, all but 1 evaluated bone marrow stimulation techniques. Microfracture of small lesions (<150 mm2) was the most common treatment utilized. Imaging and functional outcomes appeared favorable after treatment. The data did not support differences in outcomes between isolated OLTPs and OLTPs with coexisting OLTs.

CONCLUSION

Osteochondral lesions of the distal tibia most commonly occurred at the central-medial tibial plafond. Microfracture of small lesions was the most common treatment utilized, and clinical and magnetic resonance imaging results were favorable, although data were heterogeneous. Areas for future research include the following: the effect of patient factors and additional pathologies on outcomes; larger or deeper lesion treatment; more direct comparisons of outcomes between kissing or coexisting lesions and isolated lesions; and head-to-head comparison of treatments, such as microfracture, bone marrow-derived cell transplantation, and osteochondral autografts/allografts.

Patellar Tendon Orientation and Strain Are Predictors of ACL Strain In Vivo During a Single-Leg Jump

Background:

There is little in vivo data that describe the relationships between patellar tendon orientation, patellar tendon strain, and anterior cruciate ligament (ACL) strain during dynamic activities. Quantifying how the quadriceps load the ACL via the patellar tendon is important for understanding ACL injury mechanisms.

Hypothesis:

We hypothesized that flexion angle, patellar tendon orientation, and patellar tendon strain influence ACL strain during a single-leg jump. Specifically, we hypothesized that patellar tendon and ACL strains would increase concurrently when the knee is positioned near extension during the jump.

Study Design:

Descriptive laboratory study.

Methods:

Models of the femur, tibia, ACL, patellar tendon, and quadriceps tendon attachment sites of 8 male participants were generated from magnetic resonance imaging (MRI). High-speed biplanar radiographs during a single-leg jump were obtained. The bone models were registered to the radiographs, thereby reproducing the in vivo positions of the bones, ligament, and tendon attachment sites. Flexion angle, patellar tendon orientation, patellar tendon strain, and ACL strain were measured from the registered models. ACL and patellar tendon strains were approximated by normalizing their length at each knee position to their length at the time of MRI. Two separate bivariate linear regression models were used to assess relationships between flexion angle and patellar tendon orientation and between ACL strain and patellar tendon strain. A multivariate linear regression model was used to assess whether flexion angle and patellar tendon strain were significant predictors of ACL strain during the inflight and landing portions of the jump.

Results:

Both flexion angle and patellar tendon strain were significant predictors (P < .05) of ACL strain. These results indicate that elevated ACL and patellar tendon strains were observed concurrently when the knee was positioned near extension.

Conclusion:

Concurrent increases in patellar tendon and ACL strains indicate that the quadriceps load the ACL via the patellar tendon when the knee is positioned near extension.

Clinical Relevance:

Increased ACL strain when the knee is positioned near extension before landing may be due to quadriceps contraction. Thus, landing with unanticipated timing on an extended knee may increase vulnerability to ACL injury as a taut ligament is more likely to fail.

Return to Play After Revision Anterior Shoulder Stabilization: A Systematic Review

Background

Revision shoulder stabilizations are becoming increasingly common. Returning to play after revision shoulder stabilizations is important to patients.

Purpose

To evaluate the return-to-play rate after revision anterior shoulder stabilization using arthroscopic, open, coracoid transfer, or free bone block procedures.

Study Design

Systematic review; Level of evidence, 4.

Methods

All English-language studies published between 2000 and 2020 that reported on return to play after revision anterior shoulder stabilization were reviewed. Clinical outcomes that were evaluated included rate of overall return to play, level of return to play, and time to return to play. Study quality was evaluated using the Downs and Black quality assessment score.

Results

Eighteen studies (1 level 2; 17 level 4; mean Downs and Black score, 10.1/31) on revision anterior shoulder stabilization reported on return to play and met inclusion criteria (7 arthroscopic, 5 open, 3 Latarjet, and 3 bony augmentation), with a total of 564 revision cases (mean age, 27.9 years; 84.1% male). The weighted mean length of follow-up was 52.5 months. The overall weighted rate of return to play was 80.1%. The weighted mean rate of return to play was 84.0% (n = 153) after arthroscopic revision, 91.5% (n = 153) after open revision, 88.1% (n = 149) after Latarjet, and 73.8% (n = 65) after bone augmentation. The weighted mean rate of return to same level of play was 69.7% for arthroscopic revision, 70.0% for open revision, 67.1% for Latarjet revision, and 61.8% after bone block revision. There were 5 studies that reported on time to return to play, with a weighted mean of 7.75 months (4 arthroscopic) and 5.2 months (1 Latarjet). The weighted mean rates of complication (for studies that provided it) were 3.3% after arthroscopic revision (n = 174), 3.5% after open revision (n = 110), 9.3% after Latarjet revision (n = 108), and 45.8% after bone block revision (n = 72).

Conclusion

Revision using open stabilization demonstrated the highest return-to-play rate. Revision using Latarjet had the quickest time to return to play but had higher complication rates. When evaluated for return to same level of play, arthroscopic, open, and Latarjet had similar rates, and bone block had lower rates. The choice of an optimal revision shoulder stabilization technique, however, depends on patient goals. Higher-quality studies are needed to compare treatments regarding return to play after revision shoulder stabilization.

Surgical treatment for recurrent shoulder instability: factors influencing surgeon decision making

BACKGROUND

The optimal surgical approach for recurrent anterior shoulder instability remains controversial, particularly in the face of glenoid and/or humeral bone loss. The purpose of this study was to use a contingent-behavior questionnaire (CBQ) to determine which factors drive surgeons to perform bony procedures over soft tissue procedures to address recurrent anterior shoulder instability.

METHODS

A CBQ survey presented each respondent with 32 clinical vignettes of recurrent shoulder instability that contained 8 patient factors. The factors included (1) age, (2) sex, (3) hand dominance, (4) number of previous dislocations, (5) activity level, (6) generalized laxity, (7) glenoid bone loss, and (8) glenoid track. The survey was distributed to fellowship-trained surgeons in shoulder/elbow or sports medicine. Respondents were asked to recommend either a soft tissue or bone-based procedure, then specifically recommend a type of procedure. Responses were analyzed using a multinomial-logit regression model that quantified the relative importance of the patient characteristics in choosing bony procedures.

RESULTS

Seventy orthopedic surgeons completed the survey, 33 were shoulder/elbow fellowship trained and 37 were sports medicine fellowship trained; 52% were in clinical practice ≥10 years and 48% <10 years; and 95% reported that the shoulder surgery made up at least 25% of their practice. There were 53% from private practice, 33% from academic medicine, and 14% in government settings. Amount of glenoid bone loss was the single most important factor driving surgeons to perform bony procedures over soft tissue procedures, followed by the patient age (19-25 years) and the patient activity level. The number of prior dislocations and glenoid track status did not have a strong influence on respondents' decision making. Twenty-one percent glenoid bone loss was the threshold of bone loss that influenced decision toward a bony procedure. If surgeons performed 10 or more open procedures per year, they were more likely to perform a bony procedure.

CONCLUSION

The factors that drove surgeons to choose bony procedures were the amount of glenoid bone loss with the threshold at 21%, patient age, and their activity demands. Surprisingly, glenoid track status and the number of previous dislocations did not strongly influence surgical treatment decisions. Ten open shoulder procedures a year seems to provide a level of comfort to recommend bony treatment for shoulder instability.

How Are Orthopaedic Sports Medicine Physicians Triaging Cases and Using Telehealth in Response to COVID-19? A Survey of AOSSM Membership

BACKGROUND

The COVID-19 pandemic has changed the practice of orthopaedic sports medicine. The threat of COVID-19 persists, and future restrictions to elective procedures are possible. It is important to understand how sports surgeons are prioritizing surgical cases during elective case restrictions and how telehealth is being incorporated into practice.

PURPOSE

To understand how orthopaedic sports surgeons have triaged surgical sports cases and how telehealth is being utilized in response to COVID-19.

STUDY DESIGN

Cross-sectional study.

METHODS

A survey was presented to participants of the American Orthopaedic Society for Sports Medicine (AOSSM) webinar "Handling Sports and COVID-19" and distributed through email to all members of the AOSSM. The survey consisted of 25 questions with 3 sections: demographics, clinical practice, and telehealth. Descriptive statistics were performed.

RESULTS

Overall, 104 respondents participated. Respondents varied with respect to their location, type of clinical practice, and years in practice. The cases with the highest priority during triage included infections, fractures, and traumatic tendon ruptures (eg, quadriceps tendon). Before COVID-19, <14.0% of surgeons used telehealth, and 76.7% had never used telehealth. Now, however, 81.4% of respondents plan to use telehealth at least once a week in their practice. Respondents indicated postoperative visits and return patients as the most appropriate for telehealth. The majority felt that telehealth was not appropriate for new shoulder (65.9%) or knee (55.6%) evaluation. The leading barriers to telehealth use that were identified included, in decreasing order, concerns about clinical appropriateness, accuracy of physical examination, billing/reimbursement, and medicolegal concerns.

CONCLUSION

Telehealth has seen rapid adoption during the COVID-19 pandemic, and the majority of respondents plan to continue using it. It is being used more for established patients rather than new patient visits. For surgical cases, there was a clear triage priority of sports medicine cases, including infections, fractures, and traumatic tendon ruptures. Lower extremity cases had higher priority than upper extremity.

In Response to COVID-19: Current Trends in Orthopaedic Surgery Sports Medicine Fellowships

Background:

The COVID-19 (SARS-COV-2) pandemic has brought unprecedented challenges to the health care system and education models. The reduction in case volume, transition to remote learning, lack of sports coverage opportunities, and decreased clinical interactions have had an immediate effect on orthopaedic sports medicine fellowship programs.

Purpose/Hypothesis:

Our purpose was to gauge the response to the pandemic from a sports medicine fellowship education perspective. We hypothesized that (1) the COVID-19 pandemic has caused a significant change in training programs, (2) in-person surgical skills training and didactic learning would be substituted with virtual learning, and (3) hands-on surgical training and case numbers would decrease and the percentage of fellows graduating with skill levels commensurate with graduation would decrease.

Study Design:

Cross-sectional study.

Methods:

In May 2020, a survey was sent to the fellowship directors of all 90 orthopaedic sports medicine fellowships accredited by the Accreditation Council for Graduate Medical Education; it included questions on program characteristics, educational lectures, and surgical skills. A total of 37 completed surveys (41%) were returned, all of which were deidentified. Responses were compiled and saved on a closed, protected institutional server.

Results:

In a majority of responding programs (89%), fellows continued to participate in the operating room. Fellows continued with in-person clinical visits in 65% of programs, while 51% had their fellows participate in telehealth visits. Fellows were “redeployed” to help triage and assist with off-service needs in 21% of programs compared with 65% of resident programs having residents rotate off service. Regarding virtual education, 78% of programs have used or are planning to use platforms offered by medical societies, and 49% have used or are planning to use third-party independent education platforms. Of the 37 programs, 30 reported no in-person lectures or meetings, and there was a sharp decline in the number of programs participating in cadaver laboratories (n = 10; 27%) and industry courses (n = 6; 16%).

Conclusion:

Virtual didactic and surgical education and training as well as telehealth will play a larger role in the coming year than in the past. There are effects to fellows’ exposure to sports coverage and employment opportunities. The biggest challenge will be how to maintain the element of human interaction and connect with patients and trainees at a time when social distancing is needed to curb the spread of COVID-19.

Optimizing Return to Play for Common and Controversial Foot and Ankle Sports Injuries

»

Surgical decision-making should consider factors to help optimize return to play for athletes with foot and ankle injuries, including injuries to the syndesmosis, the Achilles tendon, the fifth metatarsal, and the Lisfranc complex. Understanding influential factors on return to play may help orthopaedic surgeons counsel athletes and coaches on expectations for a timeline to return to play and performance metrics.

»

Outcomes after rigid and flexible fixation for syndesmotic injuries are generally favorable. Some data support an earlier return to sport and higher functional scores with flexible fixation, in addition to lower rates of reoperation and a decreased incidence of malreduction, particularly with deltoid repair, if indicated.

»

Minimally invasive techniques for Achilles tendon repair have been shown to have a decreased risk of wound complications. Athletes undergoing Achilles repair should expect to miss a full season of play to recover.

»

Athletes with fifth metatarsal fractures have better return-to-play outcomes with surgical management and can expect a high return-to-play rate within approximately 3 months of surgery.

»

Percutaneous treatment of Lisfranc injuries may expedite return to play relative to open procedures.

Surgeon Applications of Patient Preferences in Treatment Decision Making for First-Time Anterior Shoulder Dislocation

Background

Treatment of a first-time anterior shoulder dislocation (FTASD) is sensitive to patient preferences. The operative or nonoperative management debate provides an excellent opportunity to learn how surgeons apply patient preferences in treatment decisions.

Purpose

To determine how patient preferences (repeat dislocation risk, recovery difficulties, fear of surgery, treatment costs) and surgeon factors influence a surgeon's treatment plan for FTASD.

Study Design

Cross-sectional study.

Methods

Eight clinical vignettes of hypothetical patients with FTASD (including age, sex, and activity level) were presented to members of the Magellan Society. A second set of matched vignettes with patient preferences and clinical variables were also presented. The vignettes represented scenarios in which evidence does not favor one treatment over another. Respondents were asked how they would manage each hypothetical case. Respondents also estimated the risk of redislocation for the nonoperative cases for comparison with the published rates. Finally, respondents completed a Likert-scale questionnaire to determine their perceptions on factors influencing their decisions.

Results

A total of 103 orthopaedic surgeons completed the survey; 48% practiced in an academic hospital; 79% were in practice for 10 years or longer; and 75% had completed a sports medicine fellowship. Patient preferences were the single most important factor influencing treatment recommendation, with activity type and age also important. Just 62% of the surgeon estimates of the risk of redislocation were consistent with the published rates. The inclusion of patient preferences to clinical variables changed treatment recommendations in 62.5% of our hypothetical cases. Respondents rated patient treatment preference as the leading factor in their treatment decision making.

Conclusion

Patient preferences were important when deciding the appropriate treatment for FTASD. Respondents were inconsistent when applying evidence in their decision making and estimates of recurrent instability. Decision support tools that deliver patient preferences and personalized evidence-based outcome estimates improve the quality of decision making at the point of care.

Outcome at 1 year in patients with femoral shaft fractures treated with intramedullary nailing or skeletal traction in a low-income country: a prospective observational study of 187 patients in Malawi

Background and purpose - Intramedullary nailing (IMN) is underutilized in low-income countries (LICs) where skeletal traction (ST) remains the standard of care for femoral shaft fractures. This prospective study compared patient-reported quality of life and functional status after femoral shaft fractures treated with IMN or ST in Malawi. Patients and methods - Adult patients with femoral shaft fractures managed by IMN or ST were enrolled prospectively from 6 hospitals. Quality of life and functional status were assessed using EQ-5D-3L, and the Short Musculoskeletal Function Assessment (SMFA) respectively. Patients were followed up at 6 weeks, 3, 6, and 12 months post-injury. Results - Of 248 patients enrolled (85 IMN, 163 ST), 187 (75%) completed 1-year follow-up (55 IMN, 132 ST). 1 of 55 IMN cases had nonunion compared with 40 of 132 ST cases that failed treatment and converted to IMN (p < 0.001). Quality of life and SMFA Functional Index Scores were better for IMN than ST at 6 weeks, 3 and 6 months, but not at 1 year. At 6 months, 24 of 51 patients in the ST group had returned to work, compared with 26 of 37 in the IMN group (p = 0.02). Interpretation - Treatment with IMN improved early quality of life and function and allowed patients to return to work earlier compared with treatment with ST. Approximately one-third of patients treated with ST failed treatment and were converted to IMN.

Are Weightbearing Restrictions Required After Microfracture for Isolated Chondral Lesions of the Knee? A Review of the Basic Science and Clinical Literature

CONTEXT

A strict rehabilitation protocol is traditionally followed after microfracture, including weightbearing restrictions for 2 to 6 weeks. However, such restrictions pose significant disability, especially in a patient population that is younger and more active.

EVIDENCE ACQUISITION

An extensive literature review was performed through PubMed and Google Scholar of all studies through December 2018 related to microfracture, including biomechanical, basic science, and clinical studies. For inclusion, clinical studies had to report weightbearing status and outcomes with a minimum 12-month follow-up.

STUDY DESIGN

Clinical review.

LEVEL OF EVIDENCE

Level 3.

RESULTS

Review of biomechanical and biology studies suggest new forming repair tissue is protected from shear forces of knee joint loading by the cartilaginous margins of the defect. This margin acts as a shoulder to maintain axial height and allow for tissue remodeling up to at least 12 months after surgery, well beyond current weight bearing restriction trends. A retrospective case-control study showed that weightbearing status postoperatively had no effect on clinical outcomes in patients who underwent microfracture for small chondral (<2 mm²) defects. In fact, 1 survey showed that many orthopaedic surgeons currently do not restrict weightbearing after microfracture.

CONCLUSION

This clinical literature review suggests that weightbearing restrictions may not be required after microfracture for isolated tibiofemoral chondral lesions of the knee.

Patients with depression and anxiety symptoms from adjustment disorder related to their shoulder may be ideal patients for arthroscopic rotator cuff repair

BACKGROUND

Mood symptoms may be due to shoulder-related depression or anxiety or clinical anxiety/depression. The objective of this study was to evaluate the relationship of shoulder-related and pre-existing diagnosis of depression or anxiety with changes in American Shoulder and Elbow Surgeons (ASES) score after rotator cuff repair.

METHODS

A retrospective review of prospectively collected data on subjects undergoing arthroscopic rotator cuff repair was reviewed. Preoperative and postoperative ASES, questions from the Western Ontario Rotator Cuff index questions directed to feelings of depression/anxiety related to the shoulder, and pre-existing diagnoses of depression and/or anxiety were recorded. The Wilcoxon rank sum test was used to compare changes, and Spearman's correlation was used to correlate changes in mood and ASES between male and female subjects and those with and without anxiety and/or depression.

RESULTS

One hundred seventy-one subjects (53 female; mean age, 58.0 years; standard deviation [SD], 8.5) who underwent arthroscopic rotator cuff repair were evaluated with the mean follow-up of 36.6 months (SD, 17.5). Forty-six subjects (mean age, 58.8 years; SD, 8.2) had pre-existing diagnoses of depression and/or anxiety and 125 subjects (mean age, 57.7 years; SD, 8.7) did not. Patients showed improvement in Western Ontario Rotator Cuff shoulder-related depression (Δ 22.3) and anxiety (Δ 24.7). There was a strong correlation between the change in mood symptoms and the change in ASES score, for depression (r = 0.74) and anxiety (r = 0.71). Patients with and without clinical diagnosis of anxiety or depression experienced similar changes in mood symptoms related to the shoulder and ASES scores (P = .65, P = .39). Patients' ASES scores were less correlated with changes in shoulder-related mood symptoms; however, if patients had clinical depression/anxiety compared with those without (r = 0.68 vs. 0.75, P < .0001 for depression; r = 0.56 vs. r = 0.74, P < .0001 for anxiety).

CONCLUSIONS

After rotator cuff repair, symptoms of depression/anxiety related to the shoulder improved dramatically with or without pre-existing clinical diagnosis of depression or anxiety. As the patient-reported functional outcomes of those with pre-existing clinical diagnosis of anxiety/depression improved, they did not experience as strong as an improvement in their mood symptoms as those without prior diagnoses and may benefit from directed treatment of these symptoms. Patients with shoulder-related mood symptoms only, conversely, experience a strong relationship between their improvement in function with their mood symptoms and may be ideal candidates for rotator cuff surgery. It is important for clinicians to separate mood symptoms related to adjustment disorder from the rotator cuff injury from clinical depression and anxiety.

Outcomes After Revision Anterior Shoulder Stabilization: A Systematic Review

Background

Primary shoulder stabilization is successful, but there continues to be a risk of recurrence after operative repair, particularly in the young athlete. It is important for surgeons to understand the outcomes after various revision stabilization techniques to best counsel patients and manage expectations.

Purpose

To analyze recurrent instability and revision surgery rates in patients who underwent revision anterior glenohumeral stabilization procedures with either arthroscopic repair, open repair, coracoid transfer, free bone block, or capsular reconstruction.

Study Design

Systematic review; Level of evidence, 4.

Methods

We performed a systematic review of level 2 to 4 evidence studies using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Clinical studies of revision anterior glenohumeral stabilization (arthroscopic repair, open repair, coracoid transfer, free bone block, or capsular reconstruction) with a minimum 2-year follow-up were analyzed. The rate of recurrent instability, rate of revision surgery, patient-reported outcomes, and range of motion were extracted and reported. Study methodological quality was evaluated using the Downs and Black quality assessment score.

Results

A total of 37 studies met inclusion criteria and were available for analysis: 20 studies evaluated arthroscopic repair, 8 evaluated open repair, 5 evaluated Latarjet procedure, 3 evaluated bone block, and 2 evaluated capsular reconstruction. There was 1 study included in both arthroscopic and Latarjet procedures, for a total of 1110 revision cases. There was 1 level 2 study, and the remainder were level 3 or 4 with poor Downs and Black scores. Participants analyzed were most commonly young (weighted mean age, 26.1 years) and male (78.4%). The weighted mean clinical follow-up after revision surgery was 47.8 months. The weighted mean rate of recurrent instability was 3.8% (n = 245) after the Latarjet procedure, 13.4% (n = 260) after open repair, 16.0% (n = 531) after arthroscopic repair, 20.8% (n = 72) after bone block, and 31.0% (n = 35) after capsular reconstruction. The weighted mean rate of additional revision surgery was 0.0% after bone block, 0.02% after the Latarjet procedure, 9.0% after arthroscopic repair, 9.3% after open repair, and 22.8% after capsular reconstruction. Patient-reported outcomes and objective measures of range of motion and strength improved with all revision techniques.

Conclusion

The current review identifies a deficiency in the literature pertaining to consistent meaningful outcomes and the effect of bone loss after revision shoulder stabilization. Published studies demonstrate, however, that revision shoulder stabilization using arthroscopic, open, coracoid transfer, or bone block techniques yielded satisfactory objective and patient-reported outcomes. The Latarjet procedure exhibited the lowest recurrent instability rate. This study confirms that recurrent instability remains a common problem, despite revision shoulder stabilization. The quality of research in revision shoulder stabilization remains poor, and higher quality studies are needed to establish best practices for treatment of this complex problem.

Endoscopic Proximal Hamstring Tendon Repair for Nonretracted Tears: An Anatomic Approach and Repair Technique

Proximal hamstring injuries are common, and open surgical repair with suture anchors has been the gold standard when surgical intervention is warranted. Endoscopic techniques offer the opportunity of surgical repair with smaller incisions to limit complications and expedite rehabilitation. The purpose of this technique guide is to describe a modified endoscopic technique that allows a safe and anatomic repair of proximal hamstring injuries. The patient is positioned prone with the feet at the head of the bed, table in reverse Trendelenburg, and knees flexed to 90°. Four portals are used, 3 in horizontal alignment within the gluteal fold and 1 directly superior to the ischial tuberosity. The sciatic nerve is identified, dissected, and mobilized away from the operative field. Retraction sutures help retract the gluteus maximus and further protect the sciatic nerve. Dissection is within the interval between the conjoint and semimembranosus tendons. The tendons are freed and mobilized, the ischial tuberosity is decorticated, and an anatomic repair is performed via 4 suture anchors, 2 at each tendon footprint. Advancements in arthroscopy have permitted adequate visualization and exposure of the hamstring footprint, thus allowing for an anatomic repair with increased protection of the sciatic nerve and decreased resources and cost.

The Effect of Preexisting and Shoulder-Specific Depression and Anxiety on Patient-Reported Outcomes After Arthroscopic Rotator Cuff Repair

BACKGROUND

Few studies have considered the potential effect of depression or anxiety on outcomes after rotator cuff repair.

PURPOSE

To evaluate the effect of a preexisting diagnosis of depression or anxiety, as well as the feeling of depression and anxiety directly related to the shoulder, on the American Shoulder and Elbow Surgeons (ASES) score.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

This study is a retrospective review of prospectively collected data on patients who underwent arthroscopic rotator cuff repair and were evaluated by the ASES score preoperatively and at a minimum 12 months postoperatively as part of the senior author's shoulder registry. Preexisting diagnoses of depression and/or anxiety were recorded, and questions from the Western Ontario Rotator Cuff Index directed at feelings of depression or anxiety related to the shoulder were also evaluated. The Wilcoxon rank sum test was used to compare ASES scores between patients with and without anxiety and/or depression. Spearman correlation was used to correlate questions on depression and anxiety with ASES scores.

RESULTS

A total of 187 patients (63 females, 124 males; mean age, 58.6 years, SD, 8.7 years) undergoing arthroscopic rotator cuff repair were evaluated with a mean follow-up of 47.5 months (SD, 17.4 months; range, 12-77 months). Fifty-three patients (mean age, 60 years; SD, 8.6 years) had preexisting diagnoses of depression and/or anxiety and 134 patients (mean age, 58.1 years; SD, 8.7 years) did not. Patients with depression and/or anxiety had significantly lower preoperative and postoperative ASES scores (60.7 vs 67.8, P = .014; and 74.6 vs 87.1, P = .008, respectively). The change in ASES scores from preoperative to postoperative, however, was not significantly different (18.0 vs 14.9). A higher score of depression or anxiety related to the shoulder had a negative correlation with the preoperative (r = -0.76, P < .0001; and r = -0.732, P < .0001, respectively) and postoperative (r = -0.31, P = .0001; and r = -0.31, P = .0003, respectively) ASES scores, but a positive correlation (r = 0.50, P < .0001; and r = 0.43, P < .0001, respectively) with the change in ASES scores.

CONCLUSION

Patients with a history of depression and/or anxiety have lower outcome scores preoperatively and postoperatively; however, they should expect the same amount of relief from arthroscopic rotator cuff repair as those without a history of depression or anxiety. Stronger feelings of depression or anxiety directly related to the shoulder correlated with lower preoperative and postoperative outcome scores, but a greater amount of improvement from surgery. The results from this study suggest that a preexisting diagnosis of depression or anxiety, as well as feelings of depression or anxiety directly related to the shoulder, should be considered during the management of patients with rotator cuff tears.

Surgical Anatomy of the Medial Cuneiform (Cotton) Osteotomy

Background:

The Cotton osteotomy, or dorsal-opening wedge osteotomy of the medial cuneiform (MC), is used to address medial column alignment to restore the static-triangle of support. There are many described techniques regarding the incision and osteotomy. Successful completion of the osteotomy requires knowledge of the anatomy, particularly the location of the medial dorsal cutaneous nerve (MDCN). This study describes the relationship between MDCN, tibialis anterior, extensor-hallucis-longus tendon, and ligamentous attachments to the MC. A technique to determine a safe location for the osteotomy is also described.

Methods:

Twelve fresh-frozen adult foot specimens were used for this study (7 male and 5 female). The MDCN and its branches were dissected and its relationship with the MC was documented. Osteotomy tilt angle and relationship to structures around the MC were measured.

Results:

MDCN traveled medially and distally over the dorsum of the MC, and a small branch to the MC was observed. The tilt angle was 80.1 ±1.4 degrees. There was no significant difference between the distance from the distal-articular surface to the midline of the cuneiform and to the interosseous ligament (P = .69), or between the distance from the distal-articular surface to the second tarsometatarsal joint and to the origin of the Lisfranc ligament (P = .12).

Conclusions:

The dorsal-medial-oblique incision effectively protected MDCN and the MC. We believe the osteotomy should be performed in the safe zone to maintain the stability of the opening wedge.

Clinical relevance:

The dorsal-medial-oblique incision could reduce the risk of injury to the MDCN and the tibialis-anterior tendon.

Correlation of Single Assessment Numerical Evaluation Score for Sport and Activities of Daily Living to Modified Harris Hip Score and Hip Outcome Score in Patients Undergoing Arthroscopic Hip Surgery

BACKGROUND

The Single Assessment Numerical Evaluation (SANE) is a single-question outcome score that has been shown to be a reliable measure of outcomes for shoulder and knee injuries but has not been compared with other validated outcome scores in hip pathology managed arthroscopically.

PURPOSE

To correlate SANE Activities of Daily Living (ADL) and Sport subscales with the modified Harris Hip Score (mHHS) and Hip Outcome Score (HOS) ADL and Sport subscales before and after arthroscopic hip surgery.

STUDY DESIGN

Cohort study (diagnosis); Level of evidence, 3.

METHODS

A retrospective review of a prospectively filled database of patients undergoing arthroscopic hip surgery by a single surgeon was conducted. Inclusion criteria included patients scheduled for arthroscopic hip surgery for femoroacetabular impingement, labral tear, or gluteus medius tear. Exclusion criteria included previous surgery to the hip. Outcome scores, including the mHHS, HOS ADL and Sport, and SANE ADL and Sport, were measured preoperatively and postoperatively at 3 months, 1 year, and then annually. Pearson correlation coefficients between preoperative SANE ADL and Sport and the mHHS, HOS ADL, and HOS Sport were calculated. Pearson correlation coefficients between postoperative SANE ADL and Sport and the mHHS, HOS ADL, and HOS Sport were also calculated.

RESULTS

Eighty-five patients (mean age, 37.9 years; range, 14-66 years; 57 females, 28 males) underwent arthroscopic hip surgery for assorted pathology. Mean follow-up was 8 months (range, 3-64 months). Based on the Pearson correlation coefficient, preoperative SANE ADL and Sport had a moderate correlation with the mHHS (r = 0.66; 95% CI, 0.47-0.79; P < .0001; r = 0.54; 95% CI, 0.31-0.71; P < .0001, respectively). Preoperative SANE ADL and Sport had a moderate correlation with HOS ADL (r = 0.60; 95% CI, 0.39-0.75; P < .0001) and HOS Sport (r = 0.65; 95% CI, 0.45-0.79; P < .0001). Postoperative SANE ADL and Sport had a strong correlation with the mHHS (r = 0.69; 95% CI, 0.50-0.82; P < .0001; r = 0.78; 95% CI, 0.61-0.88; P < .0001). Postoperative SANE ADL and Sport had a strong correlation with HOS ADL (r = 0.79; 95% CI, 0.65-0.88; P < .0001) and HOS Sport (r = 0.88; 95% CI, 0.78-0.94; P < .0001).

CONCLUSION

This study showed a significant correlation between SANE and mHHS in patients undergoing arthroscopic hip surgery both pre- and postoperatively. SANE ADL and Sport had a strong correlation with HOS ADL and Sport preoperatively and short-term postoperatively. SANE scores are more highly correlated with traditional subjective outcome measures during the short-term postoperative period than they are preoperatively. The SANE score provides an efficient method of assessing outcomes after hip arthroscopy.

Validation of Chichewa Short Musculoskeletal Function Assessment (SMFA) questionnaire: A cross-sectional study

Background

The Short Musculoskeletal Function Assessment (SMFA) tool measures function and quality of life in patients with musculoskeletal conditions.

Objective

This study aimed to translate and adapt culturally the SMFA into Chichewa, and assess its clinimetric properties.

Methods

The translated Chichewa version was administered to 53 patients with musculoskeletal disorders. To assess repeatability, an additional 20 patients answered the questionnaire twice over a time interval of two weeks. Internal consistency, floor and ceiling effects, and repeatability were tested; construct validity was assessed with the World Health Organization Quality of Life Assessment tool (WHOQOL-BREF).

Results

There was good internal consistency for both Dysfunction and Bothersome indices (Cronbach's alpha 0.90) and good construct validity between both indices with the WHOQOL-BREF. Pearson's correlation coefficient and intraclass correlation coefficient (ICC) for repeatability for the Dysfunction Index were 0.941 and 0.922 (95% CI: 0.772, 0.971) respectively, and 0.877 and 0.851 (95% CI: 0.629, 0.941) for the Bothersome Index respectively.

Conclusion

The translated Chichewa SMFA is a valid tool for populations that speak the Chichewa language.
