Return to Play After the Latarjet Procedure for Anterior Shoulder Instability: A Systematic Review

Rehabilitation and Return to Sport following Operative and Nonoperative Treatment of Anterior Shoulder Instability

There has been growing interest in the rehabilitation process and timing of returning an athlete to sport following the management options for anterior shoulder instability. The purpose of this article is to review the current rehabilitation and return to sport (RTS) protocols for various nonoperative and operative management strategies following anterior shoulder instability events. When appropriate in the rehabilitation protocol, RTS testing should be criteria based, rather than time based, with a special focus given to psychological readiness in order to promote successful return to athletics and prevention of recurrent instability episodes in the future.

Arthroscopic Management of the Contact Athlete with Anterior Instability

Anterior glenohumeral instability is one of the most common injuries suffered from sport. Despite padding and conditioning, the shoulder joint remains particularly vulnerable to injury, especially in the setting of contact. The overall rate of anterior instability is reported to be 0.12 injuries per 1000 athlete exposures, although this is increased up to 0.40 to 0.51 in the contact athlete. Successful treatment requires consideration of restoring stability while minimizing loss of glenohumeral motion. Common treatment strategies involve addressing the pathology that results from anterior shoulder dislocation including labral detachment as well as bony defects to the humeral head and glenoid.

Treatment of Anterior Shoulder Instability: A Comprehensive Review

Anterior shoulder instability is a complex spectrum of pathology characterized by excessive translation of the humeral head across the glenoid, leading to apprehension, subluxation, and dislocation. Diagnosis and classification require a thorough clinical history, physical examination, and imaging to appropriately determine the severity of instability. Depending on the individual patient anatomy and severity of instability, there exist many management options that are well-positioned to successfully treat this pathology and allow patients to return to prior functional levels. Treatment options available are conservative management, arthroscopic or open Bankart repair, remplissage, open or arthroscopic Latarjet, and glenoid bone grafting. Each of these options provides unique advantages for the surgeon in treating a subset of patients along the spectrum of disease. Selection of treatment modality depends upon the number of instability events, appropriate quantification, classification bone loss, presence of associated soft tissue injuries, and patient-specific goals regarding return of function. The purpose of this review was to present an evidence-based approach to the investigation, treatment selection, and follow-up of anterior shoulder instability. Individualized patient care is required to optimally address intra-articular pathology, restore stability and function, and preserve joint health for all.

Clinical outcomes, return to sport, and complications after isolated primary Latarjet versus Latarjet as a revision procedure: A systematic review and meta-analysis

BACKGROUND

The purpose of this review was to compare clinical outcomes, return to sport (RTS), and complications in comparative studies examining patients undergoing primary Latarjet procedure versus Latarjet in the revision setting following soft tissue stabilization.

METHODS

A literature search was conducted using PubMed and Scopus databases using Preferred Reporting Items for Systematic Meta-Analyses guidelines. Inclusion criteria consisted of level I to III human clinical studies reporting clinical outcomes (Visual Analogue Pain Scale [VAS]), RTS metrics, and complications in patients following primary versus revision Latarjet procedures. Study quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) criteria.

RESULTS

A total of seven studies, consisting of 1170 patients (n=1179 shoulders) with a mean age of 26.4 years, consisting of 91.9% males (n=1083/1179 shoulders), were identified. Mean final follow-up was 46.4 (mean range, 7.3-72.2) months. A total of 748 primary and 431 revision Latarjet procedures were analyzed. Complications were reported in 9.6% (range, 0%-24.2%) of patients undergoing primary and 20.2% (range, 0%-40.7%) in patients undergoing revision procedures (p=0.22). There was no significant difference in the RTS rate between patients undergoing primary (87.3%; range, 83.8%-92.1%) versus Latarjet as a revision procedure (78.9%; range, 60%-100%) (p=0.08). Moreover, no significant difference in postoperative VAS was observed in patients undergoing primary versus Latarjet as a revision procedure (p=0.21). Recurrent shoulder subluxation was significantly greater in patients undergoing revision (12.0%; n=31/259 shoulders; range, 0%-20.7%) compared to primary procedures (3.3%; n=27/511 shoulders; range, 0%-9%) (p<0.001).

DISCUSSION

Patients undergoing primary and revision Latarjet demonstrated overall similar rates of complications and return to sport. Of clinical importance, Latarjet as a revision procedure possessed a risk of recurrent subluxation 3.6 times higher than primary Latarjet. While effective, patients should be counseled regarding the differing prognosis between Latarjet as a primary or revision procedure.

Young Collision Athletes Have High Rate of Return to Play and Good Clinical Outcomes Following Open Latarjet Procedure

PURPOSE

To evaluate return to play (RTP), clinical outcomes, and recurrence rates in collision athletes 20 years of age and younger who underwent open Latarjet for anterior shoulder instability.

METHODS

A retrospective review of collision athletes 20 years of age and younger, who underwent an open Latarjet procedure by a single surgeon between the years of 2010-2020 was carried out. Inclusion criteria were 1) collision athlete, 2) underwent open Latarjet procedure, 3) 16-20 years old, and 4) minimum 24-month follow-up. Exclusion criteria were 1) other pathology of the ipsilateral shoulder and 2) noncollision athlete. Rate of RTP, time to RTP, rate of return to preinjury level, the Shoulder Instability Return to Sport after Injury score (SIRSI) score, Subjective Shoulder Value (SSV), visual analogue scale (VAS) scores, and recurrence events were recorded. Quantitative statistical analysis was carried out.

RESULTS

The study included 105 male collision athletes with a mean age of 18.6 ± 1.0 years (range: 17-20). The mean follow-up for patients was 36 ± 26.2 months. A total of 93 (88.6%) RTP at a mean time of 6.3 ± 2.2 months, with 73 (69.5%) returning to their preinjury level of participation. The mean SIRSI score was 69.2 ± 21.8, the mean VAS score was 2.3 ± 2.1, and the mean SSV score was 84.1 ± 16.8. Five patients (4.8%) redislocated their shoulder, with 4 of these requiring a further surgery (3.8%). Two patients (1.9%) reported incidents of subluxation.

CONCLUSIONS

The open Latarjet procedure in young collision athletes results in high rates of RTP, excellent functional outcomes and low recurrence rates at mid-term follow-up. Additionally, complication rates are low in this cohort.

Return to Play After Surgical Treatment for Acromioclavicular Joint Dislocation: A Systematic Review

BACKGROUND

Acromioclavicular (AC) joint dislocation is a common clinical problem among young and athletic populations. Surgical management is widely used for high-grade dislocations (Rockwood III-VI) and in high-demand athletes at high risk of recurrence.

PURPOSE

To systematically review the evidence in the literature to ascertain the rate and timing of return to play (RTP) and the availability of specific criteria for safe RTP after surgical treatment for AC joint dislocation.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

A systematic literature search based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted in the PubMed database. Clinical studies were eligible for inclusion if they reported on RTP after surgical treatment for AC joint dislocation. Statistical analysis was performed with SPSS.

RESULTS

We found 120 studies including 4327 cases meeting our inclusion criteria. The majority of patients were male (80.2%), with a mean age of 37.2 years (range, 15-85) and a mean follow-up of 34.5 months. Most were recreational athletes (79%), and the most common sport was cycling. The overall rate of RTP was 91.5%, with 85.6% returning to the same level of play. Among collision athletes, the rate of RTP was 97.3%, with 97.2% returning to the same level of play. In overhead athletes, the rate of RTP was 97.1%, with 79.2% returning to the same level of play. The mean time to RTP was 5.7 months (range, 1.5-15). Specific RTP criteria were reported in the majority of the studies (83.3%); time to return to play was the most commonly reported item (83.3%). Type III Rockwood injuries had the highest RTP rate at 98.7% and the earliest RTP at 4.9 months. Among the different surgical techniques, Kirschner wire fixation had the highest rate of RTP at 98.5%, while isolated graft reconstruction had the earliest RTP at 3.6 months.

CONCLUSION

The overall rate of RTP was reportedly high after surgical treatment for AC joint dislocation, with the majority of patients returning to their preinjury levels of sport. There is a lack of consensus in the literature for what constitutes a safe RTP, with further focus on this topic required in future studies.

Arthroscopic Coracoid Transfer in the Lateral Decubitus Position is Safe and Effective at Short-Term Follow-Up

Purpose

To report on operative and clinical outcomes in a series of shoulders treated with arthroscopic Latarjet performed in the lateral decubitus position.

Methods

Patients with shoulders that underwent arthroscopic Latarjet in the lateral decubitus position were identified. Data were retrospectively collected, including patient demographics, operative times, intra- and postoperative complications, and clinical and functional outcomes. Descriptive statistics were performed.

Results

Eighteen shoulders in 17 patients were included in the study with a mean follow-up of 14 ± 12.1 months (range, 4-39 months). The mean operative time for all procedures was 132.2 ± 18.0 minutes, and the mean operative time for the first half of the cohort was significantly longer than that of the second half (141.6 ± 14.2 minutes vs 122.8 ± 17.0 minutes, P = .02). There were no intraoperative complications, and no patients required a conversion to open surgery. One patient experienced a recurrent dislocation after a traumatic event but was able to be treated nonoperatively. Preoperative and postoperative patient-reported outcome measures (PROMs) were able to be collected on 8 of 18 patients (44.4%). Although all PROMs demonstrated improvements postoperatively, only the Single Assessment Numeric Evaluation score and American Shoulder and Elbow Surgeons Shoulder Index displayed a statistically significant increase (P < .05). Five of 8 (62.5%) shoulders demonstrated bony fusion on postoperative computed tomography scan. Of those eligible, 100% of patients returned to sport or felt that they could return if they wanted to.

Conclusions

The arthroscopic Latarjet is an effective procedure for managing glenohumeral instability and can safely be performed in the lateral decubitus position.

Female Patients Undergoing Latarjet Surgery Show Similar 2-Year Secondary Surgery Rates but Greater Risk of Emergency Department Visits Compared With a Matched Cohort of Male Patients

PURPOSE

To evaluate sex-based differences in 30-day postoperative emergency department (ED) visits, 90-day complication rates, and 2-year secondary surgery rates after the Latarjet procedure for the treatment of recurrent shoulder instability.

METHODS

A national administrative claims database was used to identify patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for shoulder subluxation or dislocation on the day of first-time stabilization with the Latarjet technique between 2015 and 2021. Male patients were matched 4:1 to female patients based on age, Elixhauser Comorbidity Index (ECI) score, and body mass index class. Rates of 30-day ED visits and 90-day complications were compared between cohorts, and risk factors for ED visits were identified by multivariate regression. The incidence of secondary surgery within 2 years was compared by Kaplan-Meier analysis.

RESULTS

Prior to matching, 1,059 male and 360 female patients met the inclusion and exclusion criteria. Subsequent 4:1 (male-to-female) matching controlling for age, ECI score, and body mass index yielded 694 male and 185 female patients who underwent the Latarjet procedure. The overall incidence of 30-day ED visits was 9.3%, with an incidence of 8.2% for male patients and 13.5% for female patients. On the basis of multivariate logistic regression, these 30-day ED visits were associated with female sex (odds ratio, 1.79; P = .029) and incrementally higher ECI scores; relative to an ECI score of 0, ECI scores of 1 to 2, 3 to 4, and 5 or greater were associated with odds ratios of 5.31 (P = .006), 8.12 (P < .001), and 12.84 (P < .001), respectively. Ninety-day complications occurred in 1.5% of the total cohort, and the incidence was not statistically different between sexes. Overall, 2-year secondary surgery rates were similar between male and female patients (5.1% and 6.7%, respectively; P = .4).

CONCLUSIONS

Female patients undergoing the Latarjet procedure for recurrent shoulder instability showed similar 90-day complication and 2-year secondary surgery rates to a matched cohort of male patients. Female sex, along with ECI score, however, was associated with a greater rate of 30-day ED visits.

Outcomes of the Latarjet procedure in female patients: A case series and matched-pair analysis

Background

The objective of this study was to retrospectively report on the outcomes of female patients undergoing the Latarjet procedure.

Methods

Female patients undergoing the Latarjet procedure with minimum 1 year follow-up were identified and contacted to obtain Numeric Pain Rating Scale (NPRS), Subjective Shoulder Value (SSV), and return to sport (RTS) data. Eligible females were then matched 1:1 with a male counterpart based on laterality and age (± 3 years), and outcomes compared.

Results

A total of 20 female patients with a mean follow-up of 73.8 months reported postoperative NPRS and SSV scores of 2.2  ±  2.3 and 69.3  ±  22.0, respectively. Of the nine athletes, 3 (33%) reported a successful RTS at a mean of 9 months. Four patients (20.0%) required reoperation at a mean of 27.1 months. The matched analysis demonstrated similar NPRS scores between male and female patients and a trend towards lower SSV scores and rates of RTS.

Conclusion

At mid-term follow-up female patients reported pain levels similar to female-specific literature reports, but overall low subjective shoulder function and RTS. Compared to propensity-matched males, females reported similar levels of pain, lower shoulder function, and lower rates of RTS, however, differences did not reach statistical significance.

Return to play following operative management of anterior shoulder instability in overhead athletes-A systematic review

Background

The purpose of this study was to systematically review the rate and timing of return to play in overhead athletes following operative management of anterior shoulder instability.

Methods

A systematic literature search based on PRISMA guidelines, utilizing the EMBASE, MEDLINE, and The Cochrane Library Databases. Eligible for inclusion were clinical studies reporting on return to play among overhead athletes following arthroscopic Bankart repair, open Latarjet procedure or Remplissage procedure.

Results

There are 23 studies included with 961 patients. Among those undergoing arthroscopic Bankart repair, the rate of return to play was 86.2%, with 70.6% returning to the same level of play and the mean time to return to play was 7.1 months. Among those undergoing an open Latarjet procedure, the rate of return to play was 80.9%, with 77.7% returning to the same level of play and the mean time to return to play was 5.1 months. Among those undergoing a Remplissage procedure, the rate of return to play was 70.6%, with 70.0% returning to the same level of play or mean time to return to play.

Discussion

Overall, there were high rates of return to play following operative management of anterior shoulder instability in overhead athletes.

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.

Criteria-based return to sport testing after open Latarjet reveals residual deficits and can be utilized for sports clearance with excellent outcomes at mean 3.6 year follow-up: A small case series of competitive athletes

OBJECTIVE

The purpose of this study was to assess the use of a criteria-based return to sport (CBRTS) test to evaluate readiness for return to play (RTP) in competitive athletes that underwent open Latarjet.

DESIGN

Retrospective case series.

METHODS

Ten competitive athletes (mean age 19.9 years) treated with open Latarjet for recurrent glenohumeral instability underwent CBRTS testing at a mean of 5.3 months postoperatively. Testing consisted of four components: 1. isometric strength, 2. isokinetic strength, 3. endurance, and 4. function. Patients failing 0 or 1 component of the test were cleared to RTP. Patients failing multiple components underwent additional deficit-based rehabilitation.

RESULTS

Of the 10 patients that tested, 4 passed their overall CBRTS test and were cleared to RTP. The remaining 6 patients failed the overall CBRTS test. Seven patients (70%) failed at least one section of the strength testing, two patients (20%) failed endurance testing, and two patients (20%) failed functional testing. At final follow-up (mean 3.6 years), 1 patient had recurrent instability (10%) and 9 patients returned to play (90%).

CONCLUSIONS

CBRTS testing may be clinically useful for return to play clearance decisions after open Latarjet procedure, as it can reveal deficits that may not be identified with time-based clearance alone.

Arthroscopic Latarjet yields better union and prevention of instability compared to arthroscopic bony Bankart repair in shoulders with recurrent anterior instability: a systematic review

PURPOSE

To determine whether arthroscopic Latarjet procedure or arthroscopic bony Bankart repair provide better outcomes in terms of rates of recurrent instability, non-union and complications, as well as clinical scores and range of motion.

METHODS

An electronic literature search was performed using PubMed, Embase®, and Cochrane databases, applying the following keywords: "Arthroscopic bony Bankart" OR "Arthroscopic osseous Bankart" AND "Arthroscopic Latarjet" OR "Arthroscopic coracoid bone block".

RESULTS

The systematic search returned 1465 records, of which 29 were included (arthroscopic bony Bankart repair, n = 16; arthroscopic Latarjet, n = 13). 37 datasets were included for data extraction, on 1483 shoulders. Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair had significantly higher instability rates (0.14; CI 0.10-0.18; vs 0.04; CI 0.02-0.06), significantly lower union rates (0.63; CI 0.28-0.91 vs 0.98; CI 0.93-1.00), and significantly lower pain on VAS (0.42; CI 0.17-0.67 vs 1.17; CI 0.96-1.38). There were no significant differences in preoperative glenoid bone loss, follow-up, complication rate, ROWE score, ASES score, external rotation, and anterior forward elevation between arthroscopic Latarjet and arthroscopic bony Bankart repair.

CONCLUSION

Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair results in significantly (i) higher rates of recurrent instability (14% vs 4%), (ii) lower union rates (63% vs 98%), but (iii) slightly lower pain on VAS (0.45 vs 1.17). There were no differences in complication rates, clinical scores, or postoperative ranges of motion.

The clinical utility of immediate post-operative PACU plain film radiographs following uncomplicated open Latarjet procedure - An institutional series of consecutive patients

Background

Immediate post-operative plain film radiograph x-rays in PACU following open Latarjet procedure are often ordered as routine. However, such radiographs utilize institutional cost and time, whilst potentially exposing patients to often-unnecessary additional radiation. This study sought to evaluate whether routine immediate post-operative radiographs following uncomplicated open Latarjet procedures impacted clinical decision-making in our institution.

Methods

From 2017 to 2020, patients who underwent open Latarjet procedure by one of four fellowship-trained upper limb surgeons at a single institution were included in this study. Post-operative radiographs taken immediately in PACU were reviewed to determine if any reported radiographic findings impacted on clinical decision-making in the immediate post-operative setting. SPSS was used for descriptive statistics.

Results

A total of 337 patients underwent an X-ray in PACU immediate after uncomplicated open Latarjet procedure. Overall, 98.5% were male (n = 332), the mean patient age of included patients was 22.9 ± 4.2 years. No patient had an abnormal finding on their post-operative x-ray. Two patients returned to the operating room in the immediate post-operative period, both requiring washout and debridement due to haemtoma or superficial wound infection.

Conclusion

The findings of this study suggest that the use of post-operative plain films in PACU following open Latarjet procedure remains a costly use of resources, with little ultimate impact on clinical decision making in the short-term post-operatively.

Outcomes of primary Latarjet vs. revision Latarjet after prior surgery for anterior shoulder instability: a systematic review and meta-analysis

BACKGROUND

Latarjet has become an increasingly popular treatment option for recurrent anterior shoulder instability. With the reported complication rates for primary Latarjet surgery, there are concerns about the complications of Latarjet as a revision surgery. It remains unclear if poor results after previous surgical management can be improved with revision Latarjet as well as with primary Latarjet. The aim of this systematic review and meta-analysis is to compare the outcomes of primary Latarjet and revision Latarjet for the treatment of anterior shoulder instability.

METHODS

A systematic search was performed on 3 databases for studies that compared primary Latarjet with revision Latarjet used after failed arthroscopic stabilization or failed free bone block procedures. From the included studies, demographic data, clinical outcome scores, range of motion measurements, and postoperative complications were obtained.

RESULTS

A total of 11 studies were included for data analysis. Compared with the primary Latarjet cohort, revision Latarjet cohorts had a higher infection rate (1.2% vs. 2.6%; RR 0.46, P = .039). The primary Latarjet group showed a greater rate of return to sport (89.7% vs. 80.5%; RR 1.12, P = .41) and less subjective feeling of instability (12.6% vs. 20.9%; RR 0.60, P = .085) compared with the revision Latarjet group; however, this was not statistically significant. There were no significant differences in complication rates, reoperation, recurrence, and range of motion between primary Latarjet and revision Latarjet groups. Clinical outcome scores such as visual analog scale and Rowe scores were not significantly different between the cohorts.

CONCLUSION

Based on the current evidence, primary Latarjet presents reduced infection rates but similar clinical outcome measures, overall complication, and range of motion measurements than revision Latarjet performed after failed prior operative treatment.

A High Rate of Return to Running Is Seen After Both Arthroscopic and Open Shoulder Surgery

PURPOSE

To determine the percentage of patients who report the ability to run 1 mile at various time points after arthroscopic and open shoulder surgery.

METHODS

We performed a retrospective review of prospectively collected data for all active-duty military patients aged 18 to 45 years who underwent shoulder surgery at a single institution over a 2-year period. The rehabilitation protocol discouraged running before 3 months, but all patients were able to return to unrestricted running at 3 months postoperatively. Patients were excluded if they lacked 1-year follow-up data. Parameters collected included demographic information and validated patient-reported outcome measures at the preoperative and short-term postoperative visits, as well as patients' ability to run at least 1 mile postoperatively.

RESULTS

A total of 126 patients were identified who underwent shoulder surgery with return-to-running data. Compared with baseline, significant improvements in patient-reported outcomes were shown at 1 and 2 years postoperatively (P = .001). The percentage of patients reporting the ability to run 1 mile postoperatively was 59% at 3 months, 74% at 4.5 months, 79% at 6 months, 83% at 12 months, and 91% at 24 months. There was no significant difference in patients undergoing shoulder surgery for instability versus non-instability diagnoses or in patients undergoing open versus arthroscopic anterior stabilization. All 11 patients unable to return to running at final follow-up had chronic lower-extremity diagnoses limiting their running ability.

CONCLUSIONS

Young military athletes undergoing arthroscopic and open shoulder surgery have a high rate of early return to running. Approximately 60% of patients report the ability to run 1 mile at 3 months postoperatively, and three-quarters of patients do so at 4.5 months. Age, sex, military occupation, underlying diagnosis or type of surgery did not influence the rate of return to running after shoulder surgery.

Previously failed Bankart repair and the duration from first dislocation to surgery were the risk factors associated with the level of return to sports after coracoid transfer

PURPOSE

This study aims to determine the rate of different levels of return to sports (RTS) in athletes undergoing the modified arthroscopic Bristow procedure and the factors associated with the level of RTS.

METHODS

The study was performed retrospectively on patients with traumatic anterior shoulder instability who underwent the modified arthroscopic Bristow procedure with a minimum follow-up of 2 years. The RTS rate, the level of return and the timing of return were assessed. Additionally, factors such as preoperative basic information, clinical outcomes, graft position, graft healing and graft absorption were analysed to investigate their correlation with the level of RTS. Multivariate regression models were used to evaluate the factors affecting the level of RTS.

RESULTS

In total, this study included 182 shoulders of 177 athletes undergoing the modified arthroscopic Bristow procedure. Of these patients, 142 (78.0%) shoulders of 137 athletes were enrolled, with a mean of 3.3-year follow-up. At the final follow-up, 134 (94.4%) shoulders were able to RTS, 123 (86.6%) shoulders were able to RTS to the pre-injury level, 52 (36.6%) shoulders could be completely "forgotten" without any psychological barrier during exercise. The multivariate logistic regression analysis identified the variable associated with RTS at the pre-injury level as previously failed arthroscopic Bankart repair (p < 0.001). As for the "forgetting" operated shoulder, the duration from first dislocation to surgery was a significant independent predictor (p = 0.034).

CONCLUSION

Although a large majority of athletes were able to RTS at the pre-injury level after the modified arthroscopic Bristow procedure, about two-thirds of the athletes felt difference in shoulders on both sides and could not completely "forget" the operated shoulder during exercise. Previously failed Bankart repair and the duration from first dislocation to surgery were the risk factors associated with the level of RTS after the modified arthroscopic Bristow procedure.

Anterior Shoulder Instability and Open Procedures: History, Indications, and Clinical Outcomes

The shoulder, being the most mobile joint in the human body, is often susceptible to dislocations and subluxations more so than other joints. As such, shoulder instability constitutes a common complaint among patients worldwide, especially those who are young, participate in contact sports, and have increased innate flexibility in their joints. Management options in the setting of instability vary between conservative and surgical options that aim to mitigate symptoms and allow return of function. Surgical options can be arthroscopic and open, with a general shift among surgeons towards utilizing arthroscopic surgery in the past several decades. Nevertheless, open procedures still play a role in managing shoulder instability patients, especially those with significant bone loss, recurrent instability, coexisting shoulder pathologies, and high risk of failure with arthroscopic surgery. In these clinical settings, open procedures, like the Latarjet procedure, open Bankart repair, glenoid bone augmentation using iliac crest autograft or distal tibial allograft, and salvage options like glenohumeral arthrodesis and arthroplasty may show good clinical outcomes and low recurrence rates. Each of these open procedures possesses its own set of advantages and disadvantages and entails a specific set of indications based on published literature. It is important to cater treatment options to the individual patient in order to optimize outcomes and reduce the risk of complications. Future research on open shoulder stabilization procedures should focus on the long-term outcomes of recently utilized procedures, investigate different graft options for procedures involving bone augmentation, and conduct additional comparative analyses in order to establish concrete surgical management guidelines.

Outcomes After Open Latarjet in Patients With or Without SLAP Lesions

Background

Up to 20% of shoulders with anterior instability are associated with superior labrum anterior-posterior (SLAP) lesions, and they remain untreated after an open Latarjet procedure. SLAP lesions can be responsible for pain and feelings of instability in high-demand patients.

Purpose/Hypothesis

The aim of this study was to compare the early functional outcomes and return to sport rates in athletes after the Latarjet procedure with versus without associated SLAP lesions. It was hypothesized that untreated SLAP lesions would not influence clinical results.

Study Design

Cohort study; Level of evidence, 3.

Methods

Inclusion criteria were athletes with anterior shoulder instability treated with Latarjet procedure, a minimum follow-up of 1 year, and an available preoperative computed tomography arthrogram. We recorded patient characteristics; type of sport; bone loss; Rowe, Single Assessment Numeric Evaluation (SANE), and 11-item Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; 5-point pain and satisfaction scores; reported apprehension; and return to sport. Patients with and without a preoperative type 5 SLAP lesion on imaging were compared.

Results

Fifty patients were included (mean age, 22 ± 5 years [range, 16-36 years]; mean follow-up, 27 ± 9 months [range, 12-42 months]). Thirty-four patients practiced contact sports, including 20 rugby players. Twelve patients (24%) had a preoperative SLAP lesion. Groups with (+) and without (-) a SLAP lesion were comparable in terms of age, sex, number of instability episodes, type of sport, and glenoid and humeral bone loss. The SLAP+ group had significantly worse outcomes with a lower Rowe score (79 ± 23 vs 91 ± 15; P = .018) and painless rate (50% vs 77%; P = .04). There were no significant differences between the groups in SANE score (SLAP+ vs SLAP-: 80% vs 87%), QuickDASH score (8% vs 8%), return to sport (83% vs 91%), apprehension (79% vs 50%), and reported satisfaction. There was 1 episode of postoperative subluxation in each group.

Conclusion

Patients who underwent an open Latarjet procedure with an associated SLAP tear more frequently reported postoperative pain than those without a SLAP lesion. Patients with untreated SLAP tears had significantly lower Rowe scores, although SANE score and return to sport were not significantly different between the groups.

Return to Preinjury-Level Sports After Arthroscopic Latarjet for Recurrent Anterior Shoulder Instability in Professional Athletes

Background

The Latarjet procedure is recommended to treat recurrent anterior shoulder instability with glenoid bone loss. Longer return-to-sport (RTS) times have been reported after the open Latarjet when compared with the arthroscopic Latarjet.

Purpose

To assess the clinical outcomes and RTS in athletes who underwent an arthroscopic Latarjet.

Study Design

Case series; Level of evidence, 4.

Methods

This study included 46 professional athletes with recurrent anterior shoulder instability who underwent an arthroscopic Latarjet between 2010 and 2016. Patients were divided by type of sport: noncollision and nonoverhead (n = 22), collision and martial arts (n = 13), and overhead (n = 11). Sport activity was evaluated with the Kerlan-Jobe Orthopaedic Clinic (KJOC) score, Subjective Patient Outcome for Return to Sports score, and RTS time. Clinical results were evaluated by Constant-Murley score, Walch-Duplay score, and range of external and internal rotation. Complication rates, recurrence of shoulder instability, and number of revision procedures were recorded. Correlation tests were used to assess the relationship between measured parameters.

Results

The mean ± SD patient age was 27.1 ± 7.3 years, and the mean follow-up was 50.7 ± 18 months. Overall, 44 patients (95.7%) returned to their previously practiced sports, and 40 (87%) returned to their preinjury levels. The RTS time was 5 ± 1.4 months, with no significant difference among sport types. KJOC and Subjective Patient Outcome for Return to Sports scores were 95.2 ± 5.6 and 9.5 ± 1, respectively. Significant pre- to postoperative improvement was seen on the Constant-Murley score (from 54.3 ± 9.4 to 87.9 ± 8.2; P = .001) and Walch-Duplay score (from 53.7 ± 7.3 to 88.1 ± 10.7; P = .001). Mean postoperative external and internal rotation was 72.8° ± 18.6° and 81.3° ± 11.3°. Procedure-related complications occurred in 10 patients (21.7%); recurrence of shoulder instability was observed in 4 (8.7%); and 4 (8.7%) underwent revision surgery. A worse Walch-Duplay score was significantly associated with longer RTS time (r = -0.39; P = .019) and lower KJOC score (r = 0.29; P = .03).

Conclusion

There was a 95.7% RTS rate after the arthroscopic Latarjet procedure, although the procedure was not free from complications.

Open Latarjet with Metal-Free Cerclage Fixation

Despite multiple modifications, the Latarjet is still the most popular procedure for recurrent anterior shoulder instability with glenoid bone loss. Partial or subtotal resorption of the graft is common, potentially leading to hardware prominence and risk of anterior soft-tissue impingement. To minimize the technical difficulties and morbidity associated with metallic implants, a coracoid and conjoint tendon transfer with a mini-open approach using Cerclage tape suture is described, as an alternative for the Latarjet procedure typically performed with metal screws and plates.

Functional Deficits After Open Latarjet Procedure and Dominance of the Operated Shoulder: An Analysis of 133 Patients

BACKGROUND

Return to sport after stabilization surgery using the open Latarjet procedure remains challenging. Additional knowledge is needed about postoperative shoulder functional deficits in order to better design return-to-sport programs.

PURPOSE

To investigate the effects of the dominance status of the operated shoulder on the shoulder functional profile recovery at 4.5 months after open Latarjet procedure.

STUDY DESIGN

Cross-sectional study; Level of evidence, 3.

METHODS

A retrospective analysis of prospectively collected data was performed. All patients who underwent the open Latarjet procedure between December 2017 and February 2021 were eligible for the study. Functional assessment at 4.5 months after the surgery was performed using the following tests: maximal voluntary isometric contractions in glenohumeral internal and external rotation, upper-quarter Y balance test, unilateral seated shot-put test, and modified closed kinetic chain upper extremity stability test, leading to 10 outcome measures. Patients whose dominant side had undergone surgery and those whose nondominant side had undergone surgery were compared with a group of 68 healthy control participants.

RESULTS

A total of 72 patients who underwent an open Latarjet procedure on the dominant side and 61 patients who underwent open Latarjet on the nondominant side were compared with 68 healthy control athletes. In patients whose dominant shoulder had undergone surgery, significant deficits for the dominant side (P < .001) and for the nondominant side (P < .001) were found in 9 of 10 functional outcome measures. Among patients whose operations were on the nondominant shoulder, significant deficits for the nondominant side (P < .001) and for the dominant side (P < .001) were found in 9 and 5 of the 10 functional outcome measures, respectively.

CONCLUSION

Regardless of dominance of the stabilized shoulder, persistent deficits in strength, stability, mobility, power, and stroke frequency were observed at 4.5 months postoperatively. Stabilization of the dominant shoulder resulted in residual surgery-related functional impairments on both sides. However, stabilization of the nondominant shoulder resulted in impairments primarily noted in the nondominant, operative shoulder.

Rehabilitation after Shoulder Instability Surgery

Shoulder instability can occur in any direction and presents across a broad spectrum including traumatic dislocations, repetitive microinstability events or subluxations, and global joint laxity. The development of pain, functional decline, and articular pathologic condition is a multifaceted process that is influenced by the underlying bony morphology, biology of the surrounding soft tissue structures, dynamic coordination of the periscapular musculature, and patient factors such as age, activity level, and associated injuries. This article will focus on the younger, active patient with instability due to deficiencies in the capsulolabral complex and dynamic stabilizers.

Arthroscopic Dynamic Anterior Stabilization Using Either Long Head of the Biceps or Conjoined Tendon Transfer for Anterior Shoulder Instability Results in a Similarly Low Recurrence Rate

PURPOSE

To compare the clinical outcomes of arthroscopic dynamic anterior stabilization (DAS) between transferring the long head of the biceps (DAS-LHB) and the conjoined tendon (DAS-CT) for anterior shoulder instability with <15% glenoid bone loss.

METHODS

From January 2016 to May 2019, a total of 63 patients who underwent DAS for recurrent anterior shoulder dislocation with <15% glenoid bone loss were included, comprising 33 patients in DAS-LHB group and 30 patients in DAS-CT group. Clinical outcomes were assessed preoperatively and at a minimum 3-year follow-up, including patient-reported outcomes, range of motion, and return to sports (RTS). Postoperative recurrent instability (including dislocation, subluxation, and subjective instability with a positive apprehension test), revisions and complications also were recorded.

RESULTS

No significant demographic characteristics difference was detected between the DAS-LHB (26.3 ± 7.9 years) and DAS-CT groups (26.0 ± 6.7 years). At the latest follow-up, there were no significant differences between the 2 groups in functional scores: Oxford Shoulder Instability Score (14.8 ± 2.8 vs 15.2 ± 3.6), Rowe score (95.9 ± 6.5 vs 93.2 ± 10.2), visual analog scale for pain (0.8 ± 1.2 vs 0.7 ± 1.7), and American Shoulder and Elbow Surgeons (95 ± 8.8 vs 95.2 ± 9.1) (all P > .218). No significant difference was detected between groups in the rates of RTS (90.1% vs 86.7%, P = .700) and RTS at previous level (78.7% vs 73.3%, P = .258), respectively. No recurrent dislocation occurred in either group. One patient felt occasional subluxation in the DAS-LHB group, and one was positive for the apprehension test in each group. One patient presented with postoperative shoulder stiffness and underwent a secondary arthroscopic debridement in the DAS-CT group.

CONCLUSIONS

Comparable rates of recurrence, complication, return to sports, and subjective shoulder function were observed between DAS-LHB and DAS-CT groups.

Clinical and Radiological Outcomes in Patients With Anterior Shoulder Instability and Glenoid Bone Loss after Arthroscopic Free Bone Block Combined With Dynamic Anterior Stabilization

BACKGROUND

As an alternative to the Latarjet procedure, the arthroscopic free bone block (FBB) procedure combined with dynamic anterior stabilization (DAS) has been recently proposed to provide both glenoid augmentation and a tendon sling effect for treating anterior shoulder instability (ASI) with glenoid bone loss.

PURPOSE

To evaluate the clinical and radiological outcomes of FBB-DAS for ASI with glenoid bone loss.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Patients who underwent arthroscopic FBB-DAS for ASI with >15% glenoid bone loss between February 2017 and March 2020 were screened and enrolled in this study. Clinical outcome measures were assessed preoperatively and at a minimum 2-year follow-up, including recurrence, complications, shoulder functional scores, range of motion, and return to sports. Postoperative computed tomography and magnetic resonance imaging were also performed.

RESULTS

Of a total of 65 patients with a mean follow-up of 46.1 ± 13.1 months, no patients experienced a recurrent dislocation or subluxation postoperatively, while 2 had a positive anterior apprehension test (3.1%). Additionally, 2 patients (3.1%) experienced complications of hematoma and shoulder stiffness, respectively. The mean visual analog scale score, American Shoulder and Elbow Surgeons score, Rowe score, and Oxford Shoulder Instability Score all improved significantly from 3.2 ± 2.4, 75.0 ± 18.9, 43.6 ± 27.3, and 33.8 ± 9.0 preoperatively to 1.3 ± 0.8, 95.1 ± 8.0, 95.5 ± 7.8, and 14.8 ± 3.5 at final follow-up, respectively (all P < .001). No difference was detected in range of motion except for 8.1° and 7.5° external rotation limitations in adduction and abduction, respectively. There were 62 patients (95.4%) who returned to sports, and 54 patients (83.1%) returned to the preinjury level. The transferred biceps tendon was intact in all 59 patients who completed radiological examination at the latest follow-up. Good bone healing was achieved in 98.3% of patients, and the glenoid bone defect decreased from 18.1% to 4.9%. Osseous and labral glenoids were significantly enlarged in width and depth on the latest magnetic resonance imaging (all P < .001).

CONCLUSION

Arthroscopic FBB-DAS provided satisfactory clinical and radiological outcomes for ASI with glenoid bone loss. Despite slight external rotation restrictions, it achieved low recurrence and complication rates, excellent shoulder functional scores, a high return-to-sports rate, and favorable graft healing and remodeling.

Increased rates of subjective shoulder instability after Bankart repair with remplissage compared to Latarjet surgery

HYPOTHESIS AND BACKGROUND

Controversy exists as to the ideal management of young active patients with subcritical glenoid bone loss and an off-track Hill-Sachs lesion, and the Latarjet and arthroscopic Bankart with remplissage are effective surgical options. The purpose of this study was to compare rates of recurrent instability and reoperation, as well as patient-reported outcome measures, between Latarjet and arthroscopic Bankart repair with remplissage surgery patients. The authors hypothesized that there would be no difference in rates of recurrent instability, reoperation, and postoperative outcomes between patients who underwent Latarjet surgery and patients who underwent Bankart repair with concomitant remplissage postoperatively.

MATERIALS AND METHODS

All patients who underwent primary shoulder stabilization for shoulder instability from 2014 to 2019 were screened. Latarjet and Bankart repair with remplissage patients were included if arthroscopic surgery was performed in response to anterior shoulder instability. Recurrent instability, revision, shoulder range of motion, return to sport (RTS), and patient-reported outcome measures (Oxford Shoulder Instability, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form scores) were compared between groups.

RESULTS

Overall, 43 Latarjet patients (age: 29.8 ± 12.1 years, 36 males 7 females) and 28 Bankart repair with remplissage patients (age: 28.2 ± 8.8 years, 25 males 3 females) were included with a mean follow-up of 3.3 ± 1.9 years. Patients who underwent Latarjet surgery had larger amounts of bone loss (19% vs. 11%, P < .001), a lower rate of off-track Hill-Sachs lesions (47% vs. 82%, P < .001), and more frequently had a history of chronic shoulder dislocations (88% vs. 43%, P < .001) compared to Bankart repair with remplissage patients. Latarjet patients less frequently reported feeling subjective shoulder instability after surgery (21% vs. 50%, P = .022), which was defined as feeling apprehension or experiencing a shoulder subluxation or dislocation event. There were no differences in rates of postoperative dislocation, revision, reoperation, or RTS, as well as patient-reported outcome scores, between groups (all P > .05).

CONCLUSION

Despite differences in osseous defects, Latarjet and Bankart repair with remplissage patients had similar rates of clinical, patient-reported, and RTS outcomes at a mean of 3.3 years postoperatively. Latarjet surgery patients may be less likely to experience subjective shoulder instability postoperatively than patients who undergo Bankart repair with concomitant remplissage.

Return to sports after arthroscopic bankart repair on the dominant shoulder in overhead athletes

BACKGROUND

Arthroscopic Bankart repair (ABR) yields good results in young athletes with anterior shoulder instability. However, the treatment for overhead athletes is challenging because recovery of range of motion is necessary for return to play and repeated shoulder motion may lead to recurrent instability. The aim of this study was to investigate the clinical outcomes and return to sports after ABR on the dominant shoulder in overhead athletes.

METHODS

This study included 24 competitive level overhead athletes who underwent ABR on their dominant shoulders. The mean age at surgery was 17.6 years, and the mean follow-up was 39.7 months. The range of bilateral shoulder motion, the Rowe score, the Japanese Shoulder Society Shoulder Instability Score (JSS-SIS), and the Japanese Shoulder Society Shoulder Sports Score (JSS-SSS) were evaluated before the surgery and at the final visit. Recurrent instability, the final level of return to sports, and the duration before returning to sports were confirmed, as well as the pre-, intra- and postoperative factors, which prohibited complete return to play.

RESULTS

There were no cases of recurrent instability. The Rowe score, JSS-SIS, JSS-SSS, and the range of flexion, abduction, internal rotation significantly improved postoperatively. Fifteen athletes (62.5%) returned to the same or superior levels without any complaint in their shoulders. The mean duration needed for a complete return was 13.3 months. The postoperative external rotation deficit in abduction was larger in the athletes who returned incompletely than those who returned completely, 7.8° and 2.3°, respectively.

CONCLUSIONS

ABR is a reliable surgery for preventing recurrent instability in overhead athletes, however the rate of a complete return to preinjury level was low and a long duration was needed for complete return to play. The postoperative external rotation may be necessary for a complete return to overhead sports.

Criteria for Return to Play After Hip Arthroscopy in the Treatment of Femoroacetabular Impingement: A Systematic Review

BACKGROUND

Femoroacetabular impingement (FAI) is a common pathology in athletes that often requires operative management in the form of hip arthroscopy.

PURPOSE

To systematically review the rates and level of return to play (RTP) and the criteria used for RTP after hip arthroscopy for FAI in athletes.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

A systematic review of the literature, based on the PRISMA guidelines, was performed using PubMed, Embase, and Scopus databases. Studies reporting outcomes after the use of hip arthroscopy for FAI were included. Outcomes analyzed were RTP rate, RTP level, and criteria used for RTP. Statistical analysis was performed using SPSS software.

RESULTS

Our review found 130 studies, which included 14,069 patients (14,517 hips) and had a mean methodological quality of evidence (MQOE) of 40.4 (range, 5-67). The majority of patients were female (53.7%), the mean patient age was 30.4 years (range, 15-47 years), and the mean follow-up was 29.7 months (range, 6-75 months). A total of 81 studies reported RTP rates, with an overall RTP rate of 85.4% over a mean period of 6.6 months. Additionally, 49 studies reported the rate of RTP at preinjury level as 72.6%. Specific RTP criteria were reported in 97 studies (77.2%), with time being the most commonly reported item, which was reported in 80 studies (69.2%). A total of 45 studies (57.9%) advised RTP at 3 to 6 months after hip arthroscopy.

CONCLUSION

The overall rate of reported RTP was high after hip arthroscopy for FAI. However, more than one-fourth of athletes who returned to sports did not return at their preinjury level. Development of validated rehabilitation criteria for safe return to sports after hip arthroscopy for FAI could potentially improve clinical outcomes while also increasing rates of RTP at preinjury levels.

Subscapularis management during open Latarjet procedure: does subscapularis split versus tenotomy matter? A systematic review and meta-analysis

BACKGROUND

The purpose of this study was to systematically review the literature to ascertain the clinical outcomes of the open Latarjet (OL) procedure using either a subscapularis-split (SS) or subscapularis tenotomy (ST) via a deltopectoral (DP) approach.

METHODS

Two independent reviewers performed a literature search using the PubMed, Embase, and Scopus databases according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Only studies reporting on outcomes of the OL procedure via a DP approach comparing both SS and ST were considered for inclusion. Meta-analysis to compare clinical outcomes was performed using RevMan software.

RESULTS

Our search found 5 studies that met our inclusion criteria, including 615 shoulders (80.8% male patients), with an average age of 27.8 ± 12.6 years (range, 15-79 years) and mean follow-up period of 50.1 ± 29.4 months (range, 12-180 months). A total of 410 shoulders and 205 shoulders underwent the OL procedure via a DP approach using the ST technique and the SS technique, respectively, with both techniques resulting in significant increases in the Rowe score postoperatively (P < .0001 for both). Additionally, significantly higher postoperative Constant scores were observed in patients who underwent the OL procedure via an SS technique vs. those in the ST group (91.8 ± 7.2 vs. 79.6 ± 16.1, P < .0001). However, meta-analysis showed nonsignificantly higher postoperative Rowe and American Shoulder and Elbow Surgeons scores in patients who underwent the OL procedure via an SS technique vs. those in the ST group (96.1 ± 2.6 vs. 86.4 ± 7.6 [P = .57] and 91.6 ± 1.3 vs. 80.6 ± 25.5 [P = .47], respectively). Furthermore, meta-analysis showed that significantly more patients in the ST group had positive lift-off test results (10.0%) when compared with the SS group at final follow-up (2.7%, P = .01). However, meta-analysis indicated that the rate of recurrent instability was trending toward significance in favor of the SS group (0% vs. 11.7%, P = .07).

CONCLUSION

Our systematic review established that in cases of OL procedures being carried out via a DP approach, the SS technique results in significantly better functional outcome measures and significantly lower rates of subscapularis insufficiency when compared with an L-shaped ST technique at medium-term follow-up. Furthermore, there were lower rates of recurrent instability that were trending toward significance in favor of the SS technique.

High rate of return to sport and excellent patient-reported outcomes after an open Latarjet procedure

HYPOTHESIS

The purpose of this study was to report return to sport, patient-reported outcomes (PROs), subjective outcomes, and complications or failures in patients who underwent open Latarjet surgery.

METHODS

Patients who underwent open Latarjet surgery performed by 2 fellowship-trained surgeons between August 2006 and November 2018 were included. Prospectively collected data were reviewed. Recurrent instability and revision surgical procedures were recorded. Subjective outcomes included return to sport and fear of reinjury or activity modification as a result of patients' instability history. PROs included the American Shoulder and Elbow Surgeons (ASES) score, Short Form 12 Physical Component Summary score, Single Assessment Numeric Evaluation score, Quick Disabilities of the Arm, Shoulder and Hand score, and satisfaction. Age, sex, sports participation, pain, primary vs. revision surgery (prior failed arthroscopic or open Bankart repair), dislocation number, glenoid bone loss, glenoid track concept, and projected glenoid track were evaluated. Failure was defined as an ASES score <70, recurrent dislocation, or revision instability surgery.

RESULTS

A total of 126 shoulders (125 patients) met the inclusion criteria, with a mean age of 28.1 years (range, 15-57 years). Of 126 shoulders, 7 (5.5%) underwent additional procedures prior to final follow-up and were excluded from outcome analyses; failure occurred in 6 of these shoulders. Mean follow-up data at 3.7 years (range, 2-9.3 years) were attained in 86.6% of patients (103 of 119). All PROs significantly improved from preoperative baseline (ASES score, from 69.7 to 90.2; Single Assessment Numeric Evaluation score, from 55.8 to 85.9; and Quick Disabilities of the Arm, Shoulder and Hand score, from 28.4 to 10.5). PROs did not differ based on sex, sports participation type, dislocation with or without sports, primary vs. revision procedure, and preoperative dislocation number. No correlations existed between PROs and age, glenoid bone loss, or number of previous surgical procedures. On-track lesions (50 of 105, 47.6%) and projected on-track lesions (90 of 105, 85.7%) correlated with better patient satisfaction but not PROs. Despite not having recurrences, 63 of 99 patients (63.6%) reported activity modifications and 44 of 99 patients (44.4%) feared reinjury. These groups had statistically worse PROs, although the minimal clinically important difference was not met. Return to sport was reported by 97% of patients (86 of 89), with 74% (66 of 89) returning at the same level or slightly below the preinjury level. Revision stabilization surgery was required 6 of 126 cases (4.8%), and 6 of 103 shoulders (5.8%) had ASES scores <70.

CONCLUSION

The open Latarjet procedure led to significant improvements in all PROs, and overall, 97% of patients returned to sport. Fear of reinjury and activity modifications were common after open Latarjet procedures but did not appear to affect clinical outcomes. On-track and projected on-track measurements correlated with better patient satisfaction but not improved PROs.

The Latarjet procedure in competitive athletes younger than 20 years old with a significant glenoid bone loss

PURPOSE

To analyze return to sports, functional outcomes, and complications following the Latarjet procedure in competitive athletes younger than 20 years old with a significant glenoid bone loss.

METHODS

Between 2010 and 2017, 60 competitive athletes younger than 20 years old with a significant glenoid bone loss were operated with the Latarjet procedure. Return to sports, range of motion, and the Rowe and the Athletic Shoulder Outcome Scoring System score were used to assess functional outcomes. Complications and bone consolidation were also evaluated.

RESULTS

The mean follow-up was 58 months and the mean age was 16.3 years. Overall, 93% were able to return to sports and 84% returned at the same level. The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after operation (P <  .001). The total complication rate was 22% and the revision rate was 1.6%. The recurrence rate was 3.3%. The bone block healed in 93% of the cases.

CONCLUSIONS

In competitive athletes younger than 20 years old with a significant glenoid bone loss, the Latarjet procedure resulted in excellent functional outcomes, with most of the patients returning to sports and at the same level they had before injury with a low rate of recurrences. However, this procedure is associated with a significant rate of complications and should preferably be performed by experienced surgeons.

Variations in common operations in athletes and non-Athletes

Background

Achieving pre-injury activity level after an injury is the fundamental goal of any orthopedic treatment for an athlete. Unfortunately, pre-injury activity levels differ significantly in different patient categories, especially in athletes and non-athlete. Hence, an outcome suitable to a non-athlete may not be adequate for an athlete. This has led to variations in the surgical approach to the same injury in an athlete and non-athlete.There is plenty of literature published comparing the outcome in athletes and non-athletes after a particular surgery. Scattered discussion about variations in these surgeries based on functional demand was done in many publications. But there was a lack of a comprehensive narrative review summarizing variations in common operations among athletes and non-athletes.

Aim

This review attempted to summarize variations in common sports operations between high functional demand patients and low demand patients and discuss the variations from the author's perspective.

Methods

A review of all the relevant papers were conducted focusing on athletes and non-athletes. Most commonly performed sports surgeries were ACL reconstruction, Meniscal repair, PCL reconstruction, and Shoulder instability surgery. A literature search was done for each commonly performed surgery using relevant keywords in PubMed and Google Scholars. Summary of papers pertinent to athletes and non-athletes were compiled to prepare this narrative review.

Results

There is a lack of papers directly comparing results in athletes and non-athletes. However, many research papers discussed surgical variations in athletes (high demand) and non-athletes (low demand) patients. There are controversies in all commonly performed surgeries, and none of the papers gives a definitive guideline on the approach to athletes and non-athlete.

Conclusion

Rather than a common suggestion on surgical variation, an individualized approach would be appropriate to decide on variation in particular surgery in both athletes and non-athletes.

Impact, incidence and prevalence of musculoskeletal injuries in senior amateur male rugby: epidemiological study

OBJECTIVES

Exposure to different types of injuries in rugby union is common. It is important to know about the injury epidemiology for medical teams care in order to optimize players´ performance and the treatment of common injuries, but there is limited specific information related to amateur rugby union. The purpose of this study is to determine the incidence, prevalence, injury burden, severity, nature of injuries sustained by senior amateur male rugby players from three clubs in Argentina during a given season.

METHODS

An observational, analytical, prospective, multicenter study was developed. Data collection was conducted from 15 March 2019 to 2 November 2019, during a complete season under the applicable standards of the Rugby Injury Consensus Group according to the Orchard Sports Injury and Illness Classification System.Incidence (injuries/1000 player-match-hours), prevalence (%), severity (time loss), injury burden (days lost/1000 player-match-hours), injured location and type of injury (%) were estimated.

RESULTS

250 players and 180 injuries were assessed. Injury prevalence was 52.4%. Incidence rate per match and training was 30.9/1000 player-match-hours, and 0.77/1000 player-training-hours, respectively.The median injury severity score was 23 (IQR 12.7-52) days lost accounting for an injury burden of 97.3/1000 player-hours. Of the total, 113 (62.8%) injuries were contact injuries. The lower limbs were the most commonly affected (58.9%). Hamstring strain injury had the highest incidence and anterior cruciate ligament tear was the most severe injury.

CONCLUSION

The prevalence, incidence, and injury burden reported in this study are unprecedented and would add knowledge for the amateur rugby union community. Trainers, physicians, and physical therapists, should consider it to improve their clinical practice.

No Difference in Outcomes After Arthroscopic Bankart Repair With Remplissage or Arthroscopic Latarjet Procedure for Anterior Shoulder Instability

Purpose

To evaluate the outcomes of arthroscopic Bankart repair with remplissage (ABRR) compared with the arthroscopic Latarjet (AL) procedure for anterior shoulder instability in patients with a labral tear and a concomitant engaging Hill-Sachs lesion.

Methods

A retrospective review of patients who underwent either ABRR or the AL procedure for a diagnosis of anterior shoulder instability with a concomitant engaging Hill-Sachs lesion between 2011 and 2019 was performed. Recurrent instability, the visual analog scale score, the Subjective Shoulder Value, the Western Ontario Shoulder Instability score, patient satisfaction, willingness to undergo surgery again, and return to work or sport were evaluated.

Results

Our study included 41 patients treated with ABRR and 26 treated with the AL procedure. At final follow-up, there was no difference between patients who underwent ABRR and those who underwent the AL procedure in the reported Western Ontario Shoulder Instability score (21.8% vs 28.2%, P = .33) or any of its components, the visual analog scale score (0.9 vs 1.4, P = .32), the Subjective Shoulder Value (78.4 vs 74.5, P = .6062), the rate of satisfaction (81.6% vs 85.6%, P = .54), or whether patients would undergo surgery again (81.6% vs 96.1%, P = .16). Overall, 5 patients in the ABRR group and 2 patients in the AL group had recurrent instability events (12.2% vs 7.8%, P = .70), with no significant difference in the rate of recurrent dislocation (12.2% vs 3.8%, P = .39).

Conclusions

In patients with anterior shoulder instability and a concomitant Hill-Sachs lesion, both ABRR and the AL procedure were shown to be reliable treatments, with a low rate of recurrent instability and excellent patient-reported outcomes in appropriately selected patients. However, our study could not determine whether there was critical glenoid bone loss in patients undergoing ABRR, and surgeons should still exercise caution in performing ABRR in patients with high-grade glenoid bone loss or in those with failed prior stabilizations.

Open Bristow Versus Open Latarjet for Anterior Shoulder Instability in Rugby Players: Radiological and Clinical Outcomes

Background:

Coracoid transfer is a reliable method for managing anterior shoulder instability in athletes who play contact sports; however, differences between the Bristow and Latarjet procedures are unclear.

Purpose:

To compare clinical outcomes and rates of bone union and bone resorption of the coracoid process between the open Bristow and open Latarjet procedures in rugby players.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Rugby players who underwent an open Bristow or an open Latarjet procedure were retrospectively reviewed for anterior shoulder instability, and 66 shoulders in the Bristow group and 35 in the Latarjet group were included. Graft union and resorption were evaluated using computed tomography at 3 months to 1 year postoperatively. Patient-reported outcome measures (American Shoulder and Elbow Surgeons score, Rowe score, and satisfaction rate) were obtained at a mean follow-up of 74 months (range, 45-160 months) for Bristow and 64 months (range, 50-76 months) for Latarjet procedures. Recurrence and the rate of return to play (RTP), frequency of pain after RTP, and retirement rate after RTP were also assessed.

Results:

In 97.1% of the Latarjet procedure cases, bone union of the coracoid was achieved at 3 months postoperatively; however, bone union was achieved in only 72.7% of the Bristow procedure cases at 6 months postoperatively. Bone resorption of the coracoid process occurred in 6.1% of shoulders after the Bristow procedure, whereas 100% of shoulders showed bone resorption after the Latarjet procedure. No statistical differences were found in outcome scores between the 2 procedures. Subluxation and persistent pain after returning to sports were identified at a significantly higher rate in the Latarjet group (5 shoulders [14%] and 9 shoulders [26%], respectively) than in the Bristow group (2 shoulders [3%] and 2 shoulders [3%]) (P = .0471 and P = .001, respectively).

Conclusion:

The Latarjet procedure had an advantage in the early and high rate of bone union but was at a disadvantage in bone resorption compared with the Bristow procedure. Subluxation and pain after returning to sports were more frequent in patients who underwent the open Latarjet procedure than in those who underwent the open Bristow procedure.

The Fragility Index of Statistically Significant Findings From Randomized Controlled Trials Comparing the Management Strategies of Anterior Shoulder Instability

BACKGROUND

Debate centering on the management of anterior shoulder instability (ASI) in recent years has led to many randomized controlled trials (RCTs) being published on the topic. The fragility index (FI) has subsequently emerged as a novel method of assessing significant findings reported in RCTs, particularly those with small sample sizes.

PURPOSE

To evaluate the FI of statistically significant findings in RCTs that reported the outcomes of management strategies of patients with ASI.

STUDY DESIGN

Systematic review; Level of evidence, 1.

METHODS

Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 2 independent reviewers performed a systematic review of RCTs focusing on the outcomes of management strategies of patients with ASI. There were 3 main categories of RCTs included: (1) nonoperative management in internal rotation (IR) versus external rotation (ER), (2) nonoperative management versus a surgical intervention, and (3) surgical management with arthroscopic Bankart repair versus open Bankart repair. The Fisher exact test was utilized to calculate the FI for the reversal of statistical significance in all statistically significant dichotomous outcomes.

RESULTS

A total of 21 RCTs were included, including 1589 shoulders (mean age, 29.4 years) with a mean follow-up of 26.8 months. There were 10 RCTs (831 shoulders) that reported outcomes after the nonoperative management of ASI in IR versus ER, with a mean FI of 6.8. There were 5 RCTs (324 shoulders) that reported outcomes comparing the nonoperative and operative management of ASI, with a mean FI of 3.5. There were 6 RCTs (434 shoulders) that reported outcomes after the operative management of ASI with either arthroscopic Bankart repair or open Bankart repair, with a mean FI of 9.6.

CONCLUSION

The overall FI of RCTs reporting the outcomes of management strategies for patients with ASI was high, suggesting a moderate fragility of statistically significant outcomes including recurrence, revision stabilization, and return to play.

High Rate of Return to Work by 3 Months Following Latarjet for Anterior Shoulder Instability

PURPOSE

To evaluate the rate and duration of return to work in patients undergoing Latarjet for failed soft-tissue stabilization or glenoid bone loss.

METHODS

Consecutive patients undergoing Latarjet from 2005 to 2015 at our institution were retrospectively reviewed at a minimum of 2 years postoperatively. Patients completed a standardized and validated work questionnaire, Western Ontario Shoulder Instability Index Survey, and a satisfaction survey.

RESULTS

Of 89 eligible patients who had Latarjet, 67 patients (75.3%) responded to the questionnaire, of whom 51 patients (76.1%) were employed within 3 years before surgery (mean age: 29.9 ± 11.8 years; mean follow-up: 54.6 ± 11.9 months) and had an average glenoid bone loss of 14.5 ± 6.1%. Fifty patients (98.0%) returned to work by 2.7 ± 3.0 months postoperatively; 45 patients (88.2%) patients returned to the same level of occupational intensity. Those who held sedentary, light, moderate, or heavy intensity occupations returned to their previous occupation at a rate of 100.0%, 93.3%, 90.0%, and 66.7% (P = .2) at a duration of 1.2 ± 1.6 months, 1.8 ± 1.9 months, 3.1 ± 3.5 months, and 6.5 ± 4.1 months (P = .001), respectively. The average postoperative Western Ontario Shoulder Instability Index score was 70.9 ± 34.2. Fifty patients (98.0%) noted at least "a little improvement" in their quality of life following surgery, with 35 patients (68.6%) noting great improvement. Furthermore, 49 patients (96.1%) reported being satisfied with their procedure, with 25 patients (49.0%) reporting being very satisfied. Four patients (7.8%) returned to the operating room, with 1 patient (2.0%) requiring arthroscopic shoulder stabilization.

CONCLUSIONS

Approximately 98% of patients who underwent Latarjet returned to work by 2.7 ± 3.0 months postoperatively. Patients with greater-intensity occupations had a longer duration of absence before returning to their preoperative level of occupational intensity. Information regarding return to work is imperative in preoperative patient consultation to manage expectations.

Analysis of Athletes Who Did Not Return to Play After Open Latarjet

Background:

The Latarjet procedure is indicated in patients with risk factors for postoperative recurrence, including collision and competitive athletes. However, the factors that prevent athletes from being able return to play (RTP) after the open Latarjet procedure are still unclear and have not been fully elucidated in the literature.

Purpose:

To evaluate patient-reported outcomes and psychological and psychosocial factors associated with athletes who did not RTP after the open Latarjet procedure compared with patients who did RTP.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

We conducted a retrospective review of athletes who underwent the open Latarjet procedure and subsequently did not RTP after a minimum of 12 months. These patients were pair matched in a 2:1 ratio for age, sex, sport, and level of preoperative play with a control group who returned to play. Patients were evaluated for their psychological readiness to return to sport using the Shoulder Instability–Return to Sport after Injury (SIRSI); other measures included the visual analog scale (VAS) for pain and Subjective Shoulder Value (SSV). Multivariate regression models were used to evaluate factors affecting RTP.

Results:

Included were 35 patients in the no-RTP group and 70 patients in the RTP group. In the no-RTP group, 7 patients (20%) passed the SIRSI benchmark of 56, with a mean overall score of 41.5 ± 21.9; in the RTP group, 57 patients (81.4%) passed the SIRSI benchmark, with a mean overall score of 74.5 ± 19.8 (P < .0001 for both). Patients in the RTP group had better SSV (88.0 vs 75.7; P <.0001) and VAS pain (1.7 vs 2.9; P = .0046) scores. Of the athletes who did not return, 18 felt persistent pain/apprehension and 17 felt that it was a natural end to their career or that their lifestyle had changed. Multiple logistic regression revealed that thoughts of having to go through surgery and rehabilitation again was significantly associated with lower RTP (P < .05).

Conclusion:

Patients who did not RTP after open Latarjet exhibited poor psychological readiness to RTP and worse pain VAS and SSV scores compared with patients who did RTP.

Clinical Outcomes in Patients With Humeral Avulsion Glenohumeral Ligament Lesions in the Setting of Anterior Shoulder Instability: A Retrospective Comparative Study

BACKGROUND

Humeral avulsion glenohumeral ligament (HAGL) lesions are often underreported but have been shown to occur in up to 10% of cases of anterior shoulder instability.

PURPOSE

To compare clinical outcomes and recurrence rates of patients with HAGL lesions undergoing open stabilization for anterior shoulder instability versus a pair-matched control.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

A retrospective review of all patients who underwent both arthroscopic and open stabilization procedures with a minimum 24-month follow-up was performed. Patients with HAGL lesions were pair-matched in a 1:6 ratio for age, sex, sport, level of preoperative play, and follow-up length with those without HAGL lesions who underwent arthroscopic Bankart repair alone. Return to play (RTP), the level of return, and the timing of return were assessed. In addition, recurrence, visual analog scale for pain (VAS), Subjective Shoulder Value (SSV), Rowe score, satisfaction, and whether they would undergo the same surgery again were compared.

RESULTS

A total of 15 patients with HAGL lesions who underwent shoulder stabilization procedures were included, with a mean age of 21.5 ± 4.1 years and mean follow-up of 53.5 ± 17.4 months, and were pair-matched to 90 patients without HAGL lesions. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SSV, satisfaction) used between the 2 groups (1.6 vs 1.7, P = .86; 83.4 vs 88.0, P = .06; 85.7 vs 87.2, P = .76; and 86.7% vs 94.5%, P = .26, respectively). In addition, there were no significant differences in terms of overall rates, levels, and timing of RTP between the 2 groups (93.3% vs 90.0%, P > .99; 80.0% vs 78.9%, P > .99; and 5.3 ± 2.2 vs 5.9 ± 2.9 months, P = .45, respectively). There was no significant difference in the rates of apprehension, subluxation, and recurrent instability between the HAGL and pair-matched control groups (26.7% vs 26.7%, P > .99; 6.7% vs 3.3%, P = .47; and 13.3% vs 6.7% months, P = .32, respectively).

CONCLUSION

Patients with anterior shoulder instability undergoing surgical stabilization with open HAGL repair demonstrate excellent functional outcomes and high rates of RTP, with low rates of recurrence in the medium term compared with a control group without HAGL lesions who underwent arthroscopic Bankart repair alone.

Anterior Shoulder Instability Part III-Revision Surgery, Rehabilitation and Return to Play, and Clinical Follow-Up-An International Consensus Statement

PURPOSE

The purpose of this study was to establish consensus statements via a modified Delphi process on revision surgery, rehabilitation and return to play, and clinical follow-up for anterior shoulder instability.

METHODS

A consensus process on the treatment using a modified Delphi technique was conducted, with 65 shoulder surgeons from 14 countries across 5 continents participating. Experts were assigned to one of 9 working groups defined by specific subtopics of interest within anterior shoulder instability.

RESULTS

The primary relative indications for revision surgery include symptomatic apprehension or recurrent instability, additional intra-articular pathologies, and symptomatic hardware failure. In revision cases, the differentiating factors that dictate treatment are the degree of glenohumeral bone loss and rotator cuff function/integrity. The minimum amount of time before allowing athletes to return to play is unknown, but other factors should be considered, including restoration of strength, range of motion and proprioception, and resolved pain and apprehension, as these are prognostic factors of reinjury. Additionally, psychological factors should be considered in the rehabilitation process. Patients should be clinically followed up for a minimum of 12 months or until a return to full, premorbid function/activities. Finally, the following factors should be included in anterior shoulder instability-specific, patient-reported outcome measures: function/limitations impact on activities of daily living, return to sport/activity, instability symptoms, confidence in shoulder, and satisfaction.

CONCLUSION

Overall, 92% of statements reached unanimous or strong consensus. The statements that reached unanimous consensus were indications and factors affecting decisions for revision surgery, as well as how prior surgeries impact procedure choice. Furthermore, there was unanimous consensus on the role of psychological factors in the return to play, considerations for allowing return to play, as well as prognostic factors. Finally, there was a lack of unanimous consensus on recommended timing and methods for clinical follow-up.

Anterior Shoulder Instability Part I-Diagnosis, Nonoperative Management, and Bankart Repair-An International Consensus Statement

PURPOSE

The purpose of this study was to establish consensus statements via a modified Delphi process on the diagnosis, nonoperative management, and Bankart repair for anterior shoulder instability.

METHODS

A consensus process on the treatment using a modified Delphi technique was conducted, with 65 shoulder surgeons from 14 countries across 5 continents participating. Experts were assigned to one of 9 working groups defined by specific subtopics of interest within anterior shoulder instability.

RESULTS

The independent factors identified in the 2 statements that reached unanimous agreement in diagnosis and nonoperative management were age, gender, mechanism of injury, number of instability events, whether reduction was required, occupation, sport/position/level played, collision sport, glenoid or humeral bone-loss, and hyperlaxity. Of the 3 total statements reaching unanimous agreement in Bankart repair, additional factors included overhead sport participation, prior shoulder surgery, patient expectations, and ability to comply with postoperative rehabilitation. Additionally, there was unanimous agreement that complications are rare following Bankart repair and that recurrence rates can be diminished by a well-defined rehabilitation protocol, inferior anchor placement (5-8 mm apart), multiple small-anchor fixation points, treatment of concomitant pathologies, careful capsulolabral debridement/reattachment, and appropriate indications/assessment of risk factors.

CONCLUSION

Overall, 77% of statements reached unanimous or strong consensus. The statements that reached unanimous consensus were the aspects of patient history that should be evaluated in those with acute instability, the prognostic factors for nonoperative management, and Bankart repair. Furthermore, there was unanimous consensus on the steps to minimize complications for Bankart repair, and the placement of anchors 5-8 mm apart. Finally, there was no consensus on the optimal position for shoulder immobilization.

Effect of Modified Arthroscopic Latarjet on Acromiohumeral Distance at 5-Year Follow-up

Background:

It is unclear whether coracoacromial ligament release during the Latarjet procedure will increase superior translation of the shoulder joint.

Purpose:

To evaluate whether a modified suture button Latarjet procedure can decrease the acromiohumeral distance (AHD).

Study Design:

Case series; Level of evidence, 4.

Methods:

A retrospective analysis was conducted among 155 patients who underwent a modified suture button Latarjet procedure between 2013 and 2015. AHD was measured on bilateral computed tomography scans taken preoperatively and on scans of the affected shoulder taken on postoperative day 1 and postoperative month (POM) 6, POM 36, and POM 60. At each time point, we recorded pain on a visual analog scale (VAS) and objective shoulder function using the American Shoulder and Elbow Surgeons, Rowe, and Walch-Duplay scores. Preoperative and final follow-up VAS and functional scores were compared using the paired t test. Pairwise comparison of AHD values at each follow-up time point were compared with the preoperative intact side using the paired t test. Intra- and interobserver reproducibility of the AHD measurements was evaluated using the intraclass correlation coefficient.

Results:

A total of 104 patients who met the criteria completed the final follow-up, which occurred at 62.6 ± 2.4 months (mean ± SD). When compared with presurgery, the VAS and all functional scores improved significantly at the last follow-up (P < .001 for all). Intra- and interobserver intraclass correlation coefficients indicated good reliability for the ADH measurements. Preoperatively, there were no differences in AHD values between the intact and affected shoulders (7.8 ± 0.8 mm for both; P = .851). The AHD values at postoperative day 1 and POM 6, POM 36, and POM 60 were 9.6 ± 0.7 mm, 8.6 ± 0.9 mm, 8.0 ± 0.8 mm, and 7.9 ± 0.8 mm, respectively, all of which were larger than those of the preoperative intact side (P < .001 for all).

Conclusion:

The modified suture button Latarjet procedure not only offered satisfactory therapeutic effects but also did not decrease the AHD at 5-year follow-up.

Clinical outcomes of revision arthroscopic Bankart repair for anterior shoulder instability: a systematic review of studies

BACKGROUND

The purpose of this study was to review the literature to ascertain the functional outcomes, recurrence rates, and subsequent revision rates following revision arthroscopic Bankart repair.

METHODS

Two independent reviewers performed a literature search based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines using the Embase, MEDLINE, and Cochrane Library databases. Studies in which arthroscopic Bankart repair was performed as a revision procedure were included. The clinical outcomes extracted and analyzed were functional outcomes, return to play, and recurrent instability.

RESULTS

Fourteen studies with 433 patients met the inclusion criteria. The majority of patients were male patients (63.7%); the average age was 26.1 years (range, 14-58 years), and the mean follow-up period was 37.6 months (range, 10-144 months). The mean Rowe score was 84.2, and 79.7% of patients had good to excellent outcomes. The rate of return to play was 78.5%, with 47.5% of patients returning to their preinjury level of play across 10 studies. The rate of recurrent instability was reported in 12 studies, with 328 shoulders demonstrating 86 instability events (26.2%). The rate of recurrent instability due to dislocation was reported in 7 studies (n = 176), with 19 events (10.8%), whereas the rate of subluxation was reported in 4 studies (n = 76), with 6 events (7.9%).

CONCLUSIONS

Revision arthroscopic Bankart repair for anterior shoulder instability was shown to result in a high rate of recurrent shoulder instability. There was a relatively poor rate of return to sport among athletes, and only about half of the patients were able to return at or above their preoperative level of ability.
