Outcomes After Arthroscopic Bankart Repair in Adolescent Athletes Participating in Collision and Contact Sports

Prognostic factors for recurrent instability in recreational athletes following arthroscopic Bankart repair: a retrospective study with an average 4.1-year follow-up

BACKGROUND

Extensive research has been conducted to investigate the short-term and long-term outcomes of arthroscopic Bankart repair, yielding varying results across different populations. However, there remains a dearth of studies specifically focused on evaluating outcomes in recreational athletes.

METHODS

A retrospective case series study was conducted on recreational athletes who underwent isolated arthroscopic Bankart repair between 2013 and 2021. The primary outcome assessed was recurrent instability, defined as dislocation or subluxation. Secondary outcomes included patient satisfaction, rates of returning to the same sports (RTS) and RTS at preinjury level, and patient-reported outcomes. Evaluation of the Rowe score, Constant score, American Shoulder and Elbow Surgeons score, and VAS pain score were performed. Prognostic factors for recurrent instability, including demographic and clinical characteristics, as well as postoperative magnetic resonance imaging (MRI) appearance of the labrum were analyzed.

RESULTS

A total of 191 patients met the selection criteria, with 150 (78.5%) available for the final follow-up. Recurrent instability occurred in 10.7% of patients, with a mean follow-up duration of 4.1 years. Younger age at surgery and more critical glenoid bone loss were significantly associated with recurrent instability (p = .038 and p = .011, respectively). The satisfaction rate regarding surgery was 90.0%. Rates of return to the same sports (RTS) and RTS at preinjury level were 82.0% and 49.3%, respectively. Clinical outcomes measured at the final follow-up were as follows: Rowe score - 92.8; Constant score - 98.0; ASES score - 98.3; VAS pain score - 0.2. Patients with recurrent instability had significantly inferior outcomes in terms of satisfaction rate, RTS at preinjury level rate, Rowe score, and Constant score (p = .000, p = .039, p = .000, and p = .015, respectively). A total of thirty-seven patients underwent MRI examination six months after surgery in our institution. The T2-weighted anterior labrum morphology was found to be poorer in patients with recurrent instability. No significant difference was observed between patients with or without recurrent instability in terms of anterior Slope, anterior labral glenoid height index (LGHI), inferior Slope, inferior LGHI, and T2-weighted inferior labrum morphology.

CONCLUSION

Arthroscopic Bankart repair can yield satisfactory medium-term outcomes for recreational athletes. Younger age at surgery, more critical glenoid bone loss, and poorer T2-weighted anterior labrum morphology assessed six months postoperatively were significantly associated with recurrent instability.

Arthroscopic Shoulder Stabilization in High School Football Players

Background

Destabilizing shoulder injuries are common in high school American football players; however, the rate of recurrent glenohumeral instability and return to play after arthroscopic labral stabilization surgery remains unknown.

Purpose/Hypothesis

The purpose of this study was to determine the rate of recurrent instability on return to competitive high school football after arthroscopic shoulder labral stabilization and capsulorrhaphy procedures. It was hypothesized that the instability rate would be greater in players with more years of eligibility remaining (YER) to play at the high school level.

Study Design

Case series; Level of evidence, 4.

Methods

Consecutive male high school football players with at least 1 YER who sustained at least 1 anterior traumatic inseason shoulder instability episode and underwent arthroscopic stabilization between 2012 and 2017 were identified. Patients and/or families were contacted by phone to discuss (1) recurrent instability episodes and (2) return to competitive sport and/or recreational athletic activity. Statistical analysis was conducted using chi-square tests to compare recurrent shoulder instability with return to play and YER.

Results

A total of 45 football players aged 14 to 17 years were included, with a mean follow-up of 4.1 years. Most patients (60%) chose not to return to competitive football, due mainly to fear of recurrent injury. Overall, the recurrent instability rate was 15.6% (7/45). The instability rate in players who returned to football was 16.7%, with 66.7% requiring revision surgery. The instability rate in patients who did not return to football was 14.8%, with no revision procedures required. In players who returned to football, the instability rate in YER group 4 was significantly higher than that in YER groups 1 to 3 (42% vs 10.5%, respectively, P = .03), with each year of play conferring an additional 10% risk of reinjury. There was a significant difference in the type of recurrent instability in players who returned to any sport versus those who did not (P = .029).

Conclusion

High school football players who returned to competitive play after arthroscopic shoulder stabilization surgery experienced a higher rate of recurrent instability that was dependent on their YER. Over half of the players chose not to return to football, with fear of reinjury being the most common reason.

Knotless Bioabsorbable Anchors Placed on the Glenoid Face for Arthroscopic Bankart Repair

BACKGROUND

Quantitative analysis of the glenoid face knotless-type anchor placement for arthroscopic Bankart repair has not been reported.

PURPOSE

To evaluate the clinical and radiologic outcomes after arthroscopic Bankart repair using knotless bioabsorbable anchors depending on the anchor location.

STUDY DESIGN

Case series, Level of evidence, 4.

METHODS

A total of 124 patients (113 men and 11 women; age, 25.6 ± 7.5 years; follow-up time, 46.5 ± 18.2 months [range, 6.2-75.5 months]) who underwent arthroscopic Bankart repair with the bioabsorbable knotless anchor between 2017 and 2021 were included in this study. Among them, 118 patients were observed for >2 years (mean, 48.2 ± 16.8 months [range, 24-75.5 months]) and were analyzed for final clinical and radiologic outcomes. Using postoperative 6-month magnetic resonance imaging, remnant glenoid (%) and labral height were measured. Shoulder range of motion (ROM), radiographic osteoarthritic change, dislocation, apprehension test, and return to sports were recorded. Three groups were established based on the remnant glenoid, which represented the percentage of the exposed glenoid anteroposterior diameter to the original diameter using the best-fit circle method-group A: lower quartile; group B: interquartile; and group C: upper quartile-and variables were analyzed.

RESULTS

Overall, the remnant glenoid was 57% ± 6.4% (range, 41.5%-75%) after the surgery. Osteoarthritic change, dislocations, and positive apprehension tests were observed in 5 (4.2%), 4 (3.4%), and 12 (10.2%) patients, respectively. A total of 34 (28.8%) and 64 (54.2%) patients could return to sports without and with restrictions, respectively. Comparing groups A, B, and C, postoperative labral height (7 ± 1, 7 ± 2, and 7 ± 1 mm; P = .623), final osteoarthritic change (1, 4, and 0; P = .440), positive apprehension tests (5, 5, and 2; P = .387), and return to sports (complete/restricted/unable, 6/18/5, 19/29/11, 9/17/4; P = .769) were not different. All ROM were similar across the groups (all P > .054), except for external rotation (ER) at postoperative 6 months (41.3°± 12.8°; 50.2°± 18.5°; and 49.8°± 15.2°; P = .050). However, ER after 1 year was similar across the groups (all P > .544). In further analysis, patients with positive apprehension tests had lower labral height compared with others (5 [4-6] mm and 7 [6-8] mm; P < .001).

CONCLUSION

In arthroscopic Bankart repair, the placement of knotless bioabsorbable anchors on the glenoid face, combined with the remplissage procedure or rotator interval closure, resulted in a low recurrence rate and moderate return to sports. However, most patients had some restrictions in returning to sports. Moreover, this technique was not associated with postoperative arthritis and shoulder stiffness, including ER deficit, which was not affected by the position of the anchor on the glenoid face for a minimum 2-year follow-up.

Results After Arthroscopic Bankart Repair in Contact Athletes Should Not Be Reported Globally Because of the High Variability in Recurrences Among the Different Contact or Collision Sports: A Systematic Review

PURPOSE

To describe and compare the recurrence rates in contact or collision (CC) sports after arthroscopic Bankart repair (ABR) and to compare the recurrence rates in CC versus non-collision athletes after ABR.

METHODS

We followed a prespecified protocol registered with PROSPERO (registration No. CRD42022299853). In January 2022, a literature search was performed using the electronic databases MEDLINE, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials), as well as clinical trials records. Clinical studies (Level I-IV evidence) that evaluated recurrence after ABR in CC athletes with a minimum follow-up period of 2 years postoperatively were included. We assessed the quality of the studies using the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool, and we described the range of effects using synthesis without meta-analysis and described the certainty of the evidence using GRADE (Grading of Recommendations, Assessment, Development, and Evaluations).

RESULTS

We identified 35 studies, which included 2,591 athletes. The studies had heterogeneous definitions of recurrence and classifications of sports. The recurrence rates after ABR varied significantly among studies between 3% and 51% (I2 = 84.9%, 35 studies and 2,591 participants). The range was at the higher end for participants younger than 20 years (range, 11%-51%; I2 = 81.7%) compared with older participants (range, 3%-30%; I2 = 54.7%). The recurrence rates also varied by recurrence definition (I2 = 83.3%) and within and across categories of CC sports (I2 = 83.8%). CC athletes had higher recurrence rates than did non-collision athletes (7%-29% vs 0%-14%; I2 = 29.2%; 12 studies with 612 participants). Overall, the risk of bias of all the included studies was determined to be moderate. The certainty of the evidence was low owing to study design (Level III-IV evidence), study limitations, and inconsistency.

CONCLUSIONS

There was high variability in the recurrence rates reported after ABR according to the different types of CC sports, ranging from 3% to 51%. Moreover, variations in recurrence among CC sports were observed, with ice hockey players being in the upper range but field hockey players being in the lower range. Finally, CC athletes showed higher recurrence rates when compared with non-collision athletes.

LEVEL OF EVIDENCE

Functional Performance Tests Reveal Promising Results at 6 Months After Shoulder Stabilization Surgery

BACKGROUND

Although athletes are mostly allowed to return to play 6 months after shoulder stabilization surgery, there are inadequate data about their functional status during this period.

HYPOTHESES

Performance tests would reveal insufficiency in the functional capacity of shoulder 6 months after stabilization surgery.

STUDY DESIGN

Prospective cohort study.

LEVEL OF EVIDENCE

Level 3.

METHODS

A total of 32 male athletes with arthroscopic anterior capsulolabral repair (AACR) were included in the study. Shoulder internal and external rotator (IR-ER) strength was assessed using isokinetic dynamometer at 60°/s and 180°/s angular velocities preoperatively and 6 months postoperatively. Shoulder function was assessed with closed kinetic chain upper extremity stability (CKCUES) test, Y balance test-upper quarter (YBT-UQ), and unilateral seated shot-put test (USSPT) at 6 months postoperation. Western Ontario shoulder instability index (WOSI) and Tampa scale of kinesiophobia (TSK) were used for the self-assessment of the shoulder. Mixed-model ANOVA was used to analyze the changes in the IR-ER strength on both shoulders. Limb symmetry index (LSI) was calculated for the IR-ER strength, YBT-UQ, and USSPT scores.

RESULTS

Shoulder IR strength was higher at 6 months postoperatively compared with preoperatively. The LSI was 76.4% and 76.6% for ER strength, and 94.2% and 94% for IR strength at 60°/s and 180°/s angular velocities, respectively, at the postoperative 6 month timepoint. The mean CKCUES test score was 21.8 ± 2.6 touches and the LSI was 94.7% for the YBT-UQ and 102.5% for the USSPT. WOSI (P < 0.001) and TSK (P = 0.001) scores were significantly lower at 6 months postoperatively.

CONCLUSION

Functional status of the patients with shoulder stabilization surgery improved considerably 6 months after surgery, yet they did not fully recover function.

CLINICAL RELEVANCE

Exercise programs focusing on shoulder ER strength and shoulder performance should be emphasized after stabilization surgery.

Pediatric and Adolescent Shoulder Instability

PURPOSE OF REVIEW

Traumatic and atraumatic shoulder instability is common in pediatric and adolescent patients. It is well-established that young patients with anterior shoulder dislocation are at high risk of recurrent instability. This review assesses the current literature pertaining to management of both anterior instability and MDI in the pediatric and adolescent populations.

RECENT FINDINGS

Current research suggests that pediatric and adolescent patients with shoulder instability have excellent outcomes following arthroscopic Bankart repair; however, higher rates of recurrent instability requiring revision surgical management have been identified in patients with more than one dislocation episode pre-operatively, those with Hill-Sachs lesions and those under age 16. The addition of the remplissage procedure to an arthroscopic Bankart repair may be useful in preventing recurrent instability for patients with large Hill-Sachs lesions. Open procedures with bony glenoid augmentation may be indicated in patients with significant glenoid bone loss, or those who have failed primary surgical management, with promising outcomes reported following the Latarjet coracoid process transfer procedure in the adolescent population. Pediatric and adolescent patients with hyperlaxity, and those participating in swimming or gymnastics are more likely to have multidirectional instability (MDI). Non-surgical management with physical therapy is the mainstay of treatment for MDI with positive outcomes reported overall. In young patients with MDI who continue to have symptoms of instability and pain that effects daily activities or sports despite an adequate and appropriate course of rehabilitation, surgical management with capsulorrhaphy may be considered, with promising outcomes reported for both open and arthroscopic techniques. Attentive selection of timing and surgical procedure for pediatric and adolescent patients with anterior shoulder instability may help to prevent recurrent instability following shoulder stabilization. Although most pediatric and adolescent patients with MDI do well following non-surgical management alone, those that fail conservative management have good outcomes following arthroscopic or open capsulorrhaphy.

Open Latarjet Versus Arthroscopic Bankart Repair for the Treatment of Traumatic Anterior Shoulder Instability in High-Demand Patients With Minimal Glenoid Bone Loss

BACKGROUND

This study compared the clinical outcomes and return to sports/work between open Latarjet and arthroscopic Bankart repair in high-demand patients with traumatic anterior shoulder instability with minimal glenoid bone loss.

METHODS

We prospectively recruited 30 patients and randomised them to either open Latarjet or arthroscopic Bankart. The mean duration of follow-up in our study was 13.27 months±2.70. All patients were males with a mean age at surgery of 28.6 years (range, 18-41 years).

RESULTS

The overall mean for the Rowe score in the 30 patients increased from 33.5±14 points preoperatively to 79.6±18 points. However, there was no statistically significant difference in the postoperative ROM (range of motion) and Rowe score among the Bankart and Latarjet groups. The main finding in our study was the time to return to sports/work which was significantly lower in the Latarjet group (5.2 months) compared to the Bankart group (seven months).

CONCLUSIONS

Open Latarjet is considered a more invasive and non-anatomical procedure, however, it is less costly with a shorter time to return to sports/work compared to the Bankart procedure, which is very crucial for high-demand patients, especially the competitive athletes targeting an early return to sports at the same pre-injury level with minimal incidence of recurrence, making the surgeon's choice very challenging.

Fourteen years of follow-up after first arthroscopic Bankart repair in athletes: functional outcomes and magnetic resonance imaging findings

BACKGROUND

The arthroscopic Bankart procedure is the most performed surgery for shoulder stabilization. Short-term to midterm results are well studied; however, long-term results over 10 years are rare.

PURPOSE

This study evaluates the long-term results and magnetic resonance imaging (MRI) findings in athletes at a mean follow-up of 14 years after an arthroscopic Bankart stabilization as well as risk factors for osteoarthritis.

METHODS

A total of 63 athletes had an arthroscopic Bankart repair between 2001 and 2008, of whom 46 patients (73.0%) participated in the final follow-up. The Constant, Rowe, and Western Ontario Shoulder Instability Index (WOSI) score and the rate of return to sports were evaluated. Glenohumeral osteoarthritis was assessed using the Samilson-Prieto classification. Known risk factors for osteoarthritis were analyzed. MRI findings (bone marrow edema, cysts, and joint effusion) were analyzed.

RESULTS

The average follow-up was 14 years. Assessment was performed on 46 athletes with an average age of 21.6 at the time of surgery. The overall redislocation rate was 21.7%. The Constant score was 96.7, the Rowe score was 83.4, and the Western Ontario Shoulder Instability Index score was 90.7 out of 100. A total of 84.8% of the athletes returned to their initial sports level. Glenohumeral osteoarthritis occurred in 28.1%. Known risk factors for osteoarthritis were confirmed. Further MRI findings were rare.

CONCLUSIONS

Arthroscopic Bankart repair in athletes shows good long-term clinical results. However, this is only in patients without osteoarthritis, which was rare, but was confirmed as a risk factor. We assume that resorption of anchors differs in patients. If it does have an impact on developing arthrosis, this should be confirmed in further studies.

Return to sports after arthroscopic Bankart repair in teenage athletes: a retrospective cohort study

BACKGROUND

Anterior shoulder instability is frequent among young athletes. Surgical treatment for this injury aims to facilitate an early return to sports (RTS). However, the rate of recurrent instability after surgery is reportedly high among young patients, and it is unclear whether surgery ensures satisfactory RTS. The purpose of this study was to verify the clinical outcomes and RTS after arthroscopic Bankart repair in competitive teenage athletes without critical bone loss in the glenoid.

METHODS

We retrospectively reviewed competitive teenage athletes who underwent arthroscopic Bankart repair. Patients with large bony defects in the glenoid, larger than 20% of the healthy side, were excluded. Clinical outcomes, recurrent instability, the final level of RTS, and the time needed for RTS were analyzed.

RESULTS

In total, 50 patients with a mean follow-up period of 44.5 ± 19.6 (range, 24-85 months) months were included. The mean age at surgery was 16.8 ± 1.7 (range, 13-19 years) years. Two patients (4.0%) experienced recurrent instability. All patients returned to sports, 96% of patients participated competitively, and 76% achieved a complete return to the pre-injury level without any complaints. The time for RTS was 6.6 ± 2.7 months (range, 3-18 months), to competitions was 9.3 ± 4.0 (range, 6-24 months) months, and to complete return was 10.6 ± 4.3 (range, 8-24 months) months. The complete return rates varied by sports type, with 82% in contact athletes, 59% in dominant-hand overhead athletes, and 100% in other athletes (P = 0.026). Other preoperative factors or concomitant lesion such as bony Bankart, superior labrum tear, or humeral avulsion of glenohumeral ligament lesion did not affect the complete RTS.

CONCLUSION

Arthroscopic Bankart repair is an effective surgical procedure for anterior shoulder instability, even among competitive teenage athletes. Sports type was the only factor associated with complete RTS after surgery.

Anatomic safe zones for arthroscopic snapping scapula surgery: quantitative anatomy of the superomedial scapula and associated neurovascular structures and the effects of arm positioning on safety

BACKGROUND

Neurovascular anatomy has not been previously quantified for the arthroscopic snapping scapula approach with the patient in the most frequent patient position ("chicken-wing" position). The purposes of this study were (1) to determine anatomic relationships of the superomedial scapula and neurovascular structures at risk during arthroscopic surgical treatment of snapping scapula syndrome (SSS), (2) to compare these measurements between the arm in the neutral position and the arm in the chicken-wing position, and (3) to establish safe zones for arthroscopic treatment of SSS.

METHODS

Eight fresh-frozen cadaveric hemi-torsos (mean age, 55.8 years; range, 52-66 years) were dissected to ascertain relevant anatomic structure locations including the (1) spinal accessory nerve, (2) dorsal scapular nerve, and (3) suprascapular nerve. A coordinate measuring device was used to collect data on the relationships of anatomic landmarks and at-risk structures during the surgical approach.

RESULTS

The dorsal scapular nerve was a mean of 24.4 mm medial to the superomedial scapula in the neutral position and 33.1 mm medial in the chicken-wing position (P < .001); the dorsal scapular nerve was 21.7 mm medial to the medial border of the scapular spine in the neutral position and 35.5 mm medial in the chicken-wing position (P < .001). The mean distance from the superomedial angle to the spinal accessory nerve intersection at the superior scapular border was 16.5 mm in the neutral position and 15.0 mm in the chicken-wing position (P = .031). The average distance from the superomedial angle to the closest point of the spinal accessory nerve was 11.6 mm and 10.4 mm in the neutral position and chicken-wing position, respectively (P = .039).

CONCLUSION

Neurologic structures around the scapula vary significantly between the neutral arm position and the chicken-wing position commonly used in the arthroscopic treatment of SSS. The chicken-wing position improves safe distances for the dorsal scapular nerve during medial-portal placement and should be considered as a primary position for arthroscopic management of SSS.

Can We Identify Why Athletes Fail to Return to Sports After Arthroscopic Bankart Repair: A Systematic Review and Meta-analysis

BACKGROUND

No previous systematic reviews have reported on athletes who fail to return to sports after arthroscopic Bankart repair.

PURPOSE

To review the literature on athletes who fail to return to sports after arthroscopic Bankart repair to determine the rate of athletes who did not return to sports and to identify the specific reasons for failure to return to sports by nonreturning athletes.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

A meta-analysis was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Three electronic databases (PubMed, Scopus, Web of Science) were queried for articles meeting the inclusion criteria. Studies were considered eligible only if reporting the rate of failure for return to sports and providing the specific reasons why athletes were unable to return to sports. All records were screened by title, abstract, and full text by 2 authors independently, with any discrepancies resolved by a third senior author. For articles selected for inclusion, data were collected on the number of athletes, average age, average follow-up time, type of sport played, rate of failure to return to sports, and specific reasons for failure to return. A random-effects model was used to conduct the meta-analysis.

RESULTS

Seventeen studies were selected for inclusion reporting on a total of 813 athletes. The calculated weighted rate of failure to return to sports after arthroscopic Bankart repair was 15.6% (95% CI, 10.9%-21.1%). A significantly higher proportion of athletes cited shoulder-dependent versus shoulder-independent reasons for failure to return to sports (81.7% vs 18.3%; P < .0001). The most cited reasons for failure to return included recurrent or persistent instability (33.3%), fear of reinjury (17.7%), apprehension (9.9%), changes in priorities or personal interest (8.5%), lack of time (7.1%), and discomfort or pain with sports (6.4%).

CONCLUSION

Our study estimated the rate of failure to return to sports after arthroscopic Bankart repair to be 15.6%, with most athletes citing shoulder-related reasons as the primary factor precluding return. Identifying the potential reasons preventing successful return to sports can guide surgeons in counseling athletes regarding postoperative expectations and addressing hesitations for returning to sports.

Postoperative recovery comparisons of arthroscopic Bankart to open Latarjet for the treatment of anterior glenohumeral instability

BACKGROUND

Recurrent anterior glenohumeral instability is a disabling pathology that can be successfully treated by arthroscopic Bankart repair or open Latarjet. However, there is a paucity of studies comparing the postoperative recovery. The purpose of this study is to evaluate the postoperative pain and functional recovery following arthroscopic Bankart versus open Latarjet.

METHODS

This is a retrospective analysis of a multicenter prospective outcomes registry database. Postoperative recovery outcomes of either a primary or revision arthroscopic Bankart and open Latarjet procedures were compared. A minimum of 1-year follow-up was required. Outcomes measures included pain visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) function score, ASES index score, and single assessment numeric evaluation (SANE) score. Overall, 787 patients underwent primary arthroscopic Bankart, 36 underwent revision arthroscopic Bankart and 75 underwent an open Latarjet procedure.

RESULTS

When compared to primary arthroscopic Bankart, open Latarjet demonstrated significantly lower VAS scores at 6 weeks (p = 0.03), 3 months (p = 0.01), and 2 years (p < 0.05). Medium-term outcomes for ASES scores and SANE score, at 1 and 2 years showed no difference. Latarjet demonstrated significantly lower (p < 0.05) preoperative early postoperative VAS pain scores with no difference at 1 year or 2 years when compared to primary Bankart. There was no difference in ASES function or index between Bankart and Latarjet. Revision Bankart provided inferior outcomes for VAS, ASES function, and ASES index when compared to primary Bankart and Latarjet at 1 year and 2 years.

CONCLUSIONS

Primary arthroscopic Bankart repair and open Latarjet provided nearly equivalent improvements in pain (VAS) and functional outcomes (ASES, SANE, VR-12) during the early recovery phase (2 years). This study supports the use of either procedure in the primary treatment of anterior glenohumeral instability. Revision arthroscopic Bankart repair demonstrated deteriorating outcomes at 1 and 2 years postoperatively.

Successful Outcomes and Return to Sport After Arthroscopic Bankart Repair in National Collegiate Athletic Association and National Football League Football Players

OBJECTIVE

To characterize recurrent instability, return to sport (RTS), and patient-reported outcomes (PROs) after arthroscopic Bankart repair for acute traumatic anterior shoulder instability in National Collegiate Athletic Association (NCAA) and National Football League (NFL) football players.

DESIGN

Case series.

SETTING

Orthopaedic and sports medicine clinic.

PARTICIPANTS

National Collegiate Athletic Association and NFL football athletes with traumatic anterior shoulder instability who underwent arthroscopic shoulder stabilization at a single institution with at least 2-year follow-up.

INTERVENTIONS OR ASSESSMENT OF RISK FACTORS OR INDEPENDENT VARIABLES

Arthroscopic Bankart repair.

MAIN OUTCOME MEASURES

Recurrent instability, RTS, patient satisfaction, the visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score.

RESULTS

Thirty-three players were included with a mean age of 23.8 years (range, 18-33 years) and a mean follow-up of 6.3 years (range, 4.1-9.3 years). One shoulder (3.0%) had a postoperative subluxation event, and 1 shoulder (3.0%) required revision surgery for issues other than instability; 93.3% of players were able to RTS at the same level or higher for at least 1 season. Mean satisfaction was 8.9 ± 2.3. Mean VAS was 1.0 ± 1.7, and mean ASES and Rowe scores were 90.7 ± 18.5 and 89.7 ± 15.2, respectively.

CONCLUSION

Arthroscopic Bankart repair is an effective surgical intervention for traumatic anterior shoulder instability in NCAA and NFL football players. At a mean 6-year follow-up, surgery restored stability in 97% of cases and 93.3% returned to their preinjury level of sport.

Surgical delay for traumatic recurrent shoulder dislocations leads to inferior functional outcomes

BACKGROUND

The effect of time interval between injury and surgery on outcomes of Bankart repair surgery has not been published previously. The purpose of this study was to assess the effect of surgical delay on functional outcomes after arthroscopic Bankart repair.

METHOD

One hundred and five athletes who underwent arthroscopic Bankart repair ± remplissage were enrolled in the study. Patients were divided into 2 groups depending upon the injury to surgery time- < 12 months (n = 19), and ≥12 months (n = 86). Depending upon the number of episodes of dislocation, patients were further categorized into 2 groups- <10 episodes (n = 66) and ≥10 episodes (n = 39). All patients were assessed post-operatively for functional outcomes (Modified Rowe's score, Constant Murley score) and return to sports at a minimum of 2 years of follow-up.

RESULTS

The mean injury to surgery time was 31.7 ± 23.1 months. The average number of episodes of dislocation before surgery were 10 (range 3-50). 49/105 (46.7%) patients returned to sports after a mean post-operative duration of 10.9 months. Athletes operated after a surgical delay of ≥12 months had inferior functional outcomes (Modified Rowe's score-89.5 ± 8.9 vs.77.4 ± 21.4; p = 0.02), lower rate of return to sports (14/19 vs. 35/86; p = 0.02) and higher mean time to return to sports (8.7 ± 1.9 vs. 11.5 ± 2.6; p < 0.05). Similarly, athletes who had ≥10 dislocations before surgery had inferior functional outcomes (Modified Rowe's score-84.5 ± 15.2 vs.72.9 ± 25.6; p = 0.004), lower rate of return to sports (37/66 vs. 12/39; p = 0.02) and higher mean time to return to sports (10.3 ± 2.4 vs. 12.6 ± 2.5; p < 0.05).

CONCLUSION

A delay in surgery (≥12 months) or dislocation episodes of ≥10 are associated with inferior functional outcomes, lower rate of return to sports and higher surgical failure rate.

Evaluation and Management of the Contact Athlete's Shoulder

Shoulder injuries are common in contact athletes and vary in severity because of the required complex interplay of shoulder stability and range of motion for proper function. Pathology varies based on sport but most commonly includes shoulder instability, acromioclavicular injuries, traumatic rotator cuff tears, and brachial plexus injuries. Acute management ranges from reduction of shoulder dislocations to physical examination to determine the severity of injury. Appropriate radiographs should be obtained to evaluate for alignment and fracture, with magnetic resonance imaging commonly being necessary for accurate diagnosis and management. Treatments range from surgical stabilization in shoulder instability to repeat examinations and physical therapy. Return-to-play decision making can be complex with avoidance of reinjury and player safety being of utmost concern. Appropriate evaluation and treatment are vital because repeat injury can lead to long-term effects due to the relatively high effectsometimes seen in contact sports.

Trends in Medial Ulnar Collateral Ligament Repair and Reconstruction From 2007 to 2016: A Population-Based Study of a Large Private Insurance Database

Background: Ulnar collateral ligament (UCL) reconstruction and UCL repair of the elbow are commonly performed procedures, resulting in high return-to-play rates. Whether the incidence rate of UCL reconstruction vs UCL repair has changed over time is not currently known. Purpose/Questions: We sought to assess temporal trends in the incidence rates of UCL repair and UCL reconstruction and to identify factors associated with UCL reconstruction. We hypothesized that UCL repair would demonstrate an increased incidence overall in recent years with an associated decline in UCL reconstruction rates. Methods: Using the PearlDiver Research Program to query the Humana administrative claims database, we identified patients who had undergone UCL repair and/or reconstruction from 2007 to 2016. Patients were stratified by age (15-19; 20-29; 30-49 years), sex, and year (2007-2011 vs 2012-2016). Poisson regression analysis (continuous variables) was used to calculate the incidence risk ratio (IRR); chi-square tests were performed for categorical variables, and odds ratios were calculated with 95% confidence intervals (CI). Results: The incidence rate of UCL repair was greater in 2012-2016 than in 2007-2011 (IRR: 1.86, 95% CI: 1.16-2.96). The incidence rate of UCL reconstruction vs UCL repair was greater for patients aged 15 to 19 years (IRR: 3.37, 95% CI: 1.97-5.77) but not patients aged 20 to 29 years (IRR: 0.89, 95% CI: 0.49-1.59) as compared with patients aged 30 to 49. Males aged 19 years were more likely than females to undergo UCL reconstruction (IRR: 10.09, 95% CI: 1.37-3.45). Conclusion: While UCL procedures are becoming more popular, our retrospective analysis showed that young males are preferentially treated with UCL reconstruction, warranting further investigation into these trends.

Team Approach: Treatment of Shoulder Instability in Athletes

»

Shoulder instability is a complex problem with a high rate of recurrence in athletes. Treatment of a first-time subluxation or dislocation event is controversial and depends on patient-specific factors as well as the identified pathology.

»

Athletic trainers and physical therapists are an integral part of the treatment team of an in-season athlete who has experienced a shoulder instability event. Through comprehensive physiological assessments, these providers can effectively suggest modifications to the patient's training regimen as well as an appropriate rehabilitation program.

»

Surgical intervention for shoulder stabilization should use an individualized approach for technique and timing.

»

A team-based approach is necessary to optimize the care of this high-demand, high-risk population.

Return-to-Sport Criteria After Upper Extremity Surgery in Athletes-A Scoping Review, Part 1: Rotator Cuff and Shoulder Stabilization Procedures

Background:

Standardized criteria are lacking to guide patient return to sport (RTS) after rotator cuff surgery (RCS) or shoulder stabilization surgery (SSS).

Purpose:

To describe RTS criteria used after RCS and SSS in athletic populations.

Study Design:

Scoping review; Level of evidence, 4.

Methods:

This scoping review was based on the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses–Scoping Review) guidelines. A total of 5 electronic databases (MEDLINE, Scopus, SPORTDiscus, Embase, Google Scholar Advanced search) and the gray literature were searched for English-language studies that reported at least 1 RTS criterion in athletes after shoulder surgery. Studies were assigned to the RCS or SSS subgroup based on the primary procedure performed. Data were extracted and summarized as frequencies or arithmetic mean and standard deviation.

Results:

Included were 52 studies and 2706 athletes (2206 male, 500 female, with a mean age of 28.8 ± 1.8 years). The RCS group consisted of 14 studies and the SSS group consisted of 38 studies. Time from surgery was the most common RTS criterion reported overall (37/52 studies; 71%) as well as within the RCS (93%) and SSS (63%) subgroups. Muscle strength (25/52 studies; 48%) and range of motion (23/52; 44%) were used by almost half of the included articles. RTS criteria reported less often were absence of pain, successful completion of sport-specific or position-specific test, proprioception, radiographic evaluation, patient-surgeon agreement, minimum time required to participate in pain-free throwing, and satisfactory scapulothoracic mechanics. All studies used 1 to 3 of the above RTS criteria; however, the definition of each criterion differed among the included articles.

Conclusion:

Time from surgery was the most commonly reported RTS criterion after RCS or SSS in athletes, whereas muscle strength and range of motion were used by almost half of the articles. There was high heterogeneity in the definition of each RTS criterion used among the included studies, which also used different combinations of 1 to 3 RTS criteria. These results suggest the need to better define quantitative and qualitative RTS criteria in athletes undergoing rotator cuff and shoulder stabilization procedures in order to safely return athletes to sport.

Outcomes After Arthroscopic Anterior Shoulder Stabilization in Professional Handball Players

Background:

Although numerous studies have reported on the redislocation rate and functional results of arthroscopic treatment for anterior shoulder instability in athletes, they have not disclosed outcomes in the high-risk group of elite handball players.

Purpose:

To investigate the postoperative outcomes of arthroscopic treatment for anterior shoulder instability as well as the return-to-sport (RTS) rate in professional handball players.

Study Design:

Case series; Level of evidence, 4.

Methods:

Involved in this study were 44 competitive handball players (47 shoulders) who underwent arthroscopic anterior capsulolabral reconstruction between 2010 and 2018 and had a minimum follow-up of 24 months. After surgery, patients completed a questionnaire that collected Rowe and American Shoulder and Elbow Surgeons (ASES) scores and RTS data, and we compared these results with their preoperative scores. We also compared results according to the following subgroups: true dislocations versus recurrent subluxations, younger (<20 years) versus older (≥20 years) age, male versus female sex, and shorter versus longer duration of instability. Statistical analysis included the paired-samples t test and nonparametric Fisher exact test.

Results:

The mean follow-up period was 52.2 ± 21.4 months. There were 4 shoulders (9%) with recurrent instability. There were significant preoperative to postoperative improvements in the mean Rowe score (from 45.2 to 91.8) and mean ASES score (from 70.6 to 95.7) (P < .001 for both). Overall, the RTS rate was 83%, and 64% (30/47 shoulders) were able to return to their preinjury level. The RTS rate was significantly lower in the younger players than in the older players (46% vs 86%, respectively; P = .005).

Conclusion:

The study results indicated that handball players with anterior shoulder instability can be treated using arthroscopic labral reconstruction successfully and 83% of the athletes were able to RTS activity. The handball players aged ≥20 years returned to their preinjury level of sport at a higher rate than did those aged <20 years.

[Shoulder instability: review of current concepts of diagnosis and treatment]

OBJECTIVE

To conduct a systematic review of modern literature data on the modern approaches in diagnosis and treatment of shoulder instability.

MATERIAL AND METHODS

Searching for literature data was performed using the Pubmed and Google Scholar databases.

RESULTS

The authors analyzed the results of conservative treatment of patients with shoulder instability and emphasized higher risk of instability recurrence, degeneration of anatomical structures and functional impairment in these patients. Surgery is advisable to restore shoulder stability and normalize its function. Several methods for stabilizing the shoulder have been proposed.

The approaches to diagnosis and treatment of shoulder instability have been updated.

CONCLUSION

Successful treatment of shoulder instability is based on qualitative and complete assessment of soft tissues and bone structures. An individual approach considering bone tissue deficiency and individual needs of the patient is required.

Limited Predictive Value of the Instability Severity Index Score: Evaluation of 217 Consecutive Cases of Recurrent Anterior Shoulder Instability

PURPOSE

To review the existing variables and their ability to predict recurrence of shoulder instability as it relates to the Instability Severity Index Score (ISIS), as well as evaluate any other pertinent imaging and patient history variables that may impact risk of recurrent anterior instability after arthroscopic Bankart repair.

METHODS

All consecutive patients with recurrent anterior shoulder instability and who had arthroscopic instability repair were identified. Exclusion criteria were prior surgery on the shoulder, posterior or multidirectional instability, instability caused by seizure disorder, or a rotator cuff tear. All ISIS variables were recorded (age <20 years, sport type and level, hyperlaxity, Hill-Sachs on anteroposterior external rotation radiograph, loss of glenoid contour on anteroposterior radiograph), as well as additional variables: (1) number of instability events; (2) total time of instability; (3) glenoid bone loss (GBL) percent; and (4) Hill-Sachs measures (H/L/W/D/Volume). Postoperative outcomes were assessed based on the Western Ontario Shoulder Instability Index (WOSI), Single Assessment Numeric Evaluation (SANE) scores, and American Shoulder and Elbow Surgeons (ASES) scores, and recurrent anterior instability. Regression analysis was used to determine preoperative variables that predicted outcomes and failures.

RESULTS

There were 217 consecutive patients (209 male patients [96.5%], 8 female patients [3.5%]) who met the inclusion criteria and were all treated with a primary arthroscopic shoulder stabilization during a 3.5-year period (2007-2011), with a mean follow-up time of 42 months (range, 26-58). The mean age at first instability event was 23.9 years (range, 16-48 years) and the mean cumulative ISIS score for the overall group was 3.6 (range, 1-6). Outcomes were improved from mean preoperative (WOSI = 1,050/2,100; ASES = 61.0; SANE = 52.5) to postoperative (WOSI = 305/2,100; ASES = 93.5; SANE = 95.5). A total of 11.5% (25/217) of patients had evidence of recurrent instability (subluxation or dislocation). Additionally, all 25 patients who failed postoperatively also had consistently inferior ASES, SANE, and WOSI outcome scores when compared with successfully treated patients. Factors associated with failure were GBL greater than 14.5% (P < .001), total time of instability symptoms greater than 3 months (P = .03), Hill-Sachs volume greater than 1.3 cm³ (P = .02), contact sports participation (P = .05), and age 20 years or younger (P < .01). There was no correlation in outcomes with Hill-Sachs on presence of glenoid contour loss on radiograph (P = .07), participation sports, or ISIS (mean = 3.4 success vs 3.9 failure, P > .05).

CONCLUSIONS

At a mean follow-up of 42 months was an 11.5% failure rate after arthroscopic Bankart stabilization surgery. This study shows no correlation between treatment outcome and the ISIS measure, given a mean score of 3.4 for the overall cohort with little difference identified in those who failed. However, several important parameters previously unidentified were detected including, GBL greater than 14.5%, Hill-Sachs volume greater than 1.3 cm³, and duration of instability symptoms (>3 months). The ISIS may need to be redesigned to incorporate variables that more accurately portray the actual risk of failure after arthroscopic stabilization, including quantification of both glenoid and humeral head bone loss.

Evolving Concepts in the Management of Shoulder Instability

BACKGROUND

Shoulder instability exists on a spectrum ranging from subtle subluxation and pain to dislocation and can be the result of a traumatic event or repetitive microtrauma. Shoulder instability can result in significant disability and often requires surgical intervention, especially amongst younger, active patient populations. The optimal treatment of shoulder instability depends on the degree of instability and concomitant pathology involving the labrum, capsule, and bony anatomy of the glenoid and humeral head. Even with surgical intervention, recurrent instability remains a relatively common and difficult problem to address.

PURPOSE

With a focus on anterior instability, the purpose of this review article is to discuss the current assessment and treatment of shoulder instability, and highlight current and future treatment modalities, as well as to identify current trends and deficiencies in our current management. We also provide an algorithm for the surgical treatment of anterior shoulder instability.

METHODS

Literature databases were extensively searched for recent articles related to the mechanism, diagnosis, and treatment of shoulder instability to comprise a comprehensive review.

CONCLUSION

Although there are multiple treatment modalities available for shoulder instability, such as nonoperative management, open and arthroscopic Bankart repair, Latarjet procedures, and remplissage, orthopaedic surgeons continue to learn about the most appropriate method of management as increasing long-term outcomes become available.

Anterior Glenohumeral Instability in the Adolescent Athlete

Glenohumeral instability is multifactorial and has both static and dynamic elements. The initial management of first-time dislocations has become increasingly controversial, although recent evidence supports operative treatment for adolescents who participate in contact sports. Risk factors for recurrent glenohumeral instability include adolescent age, hyperlaxity, glenoid bone loss, off-track Hill-Sachs lesions, and fixation with <=3 anchors. High rates of return to sport can be expected when the surgical plan is tailored to individual pathology.

Outcomes of the arthroscopic Bankart procedure in Irish collision sport athletes

BACKGROUND

While there is an abundance of research examining the outcomes of the arthroscopic Bankart repair in collision athletes, very few studies have involved the unique Irish collision sport athlete population. The previously held belief that collision athletes need to be treated with open surgery, due to the high traumatic forces the shoulder is subjected to in these sports, may no longer be true in the context of modern arthroscopic techniques and implants.

AIMS

To report the outcomes of the arthroscopic Bankart procedure in the unique Irish collision athlete population.

METHOD

Retrospective review conducted in 2018. Data was obtained from collision sport athletes using customised questionnaires and validated, standardised outcome measure tools. Participants were selected using inclusion and exclusion criteria.

RESULTS

Fifty-four patients were included in the study. The average age at primary injury was 19.9 years (range 13-35 years). The rate of recurrent dislocation was 21% (12/57) with a mean follow up time of 24 months (range 7 to 48 months). The mean patient reported outcome measure (PROM) scores were as follows: ASES = 90.8, WOSI = 316.4, SSV = 79%. Six patients failed to return to their sport. Eighty-seven percent of the cohort returned to their sport, with a mean time to return of 7.25 months. Patients who experienced recurrent instability after arthroscopic Bankart had a younger age at primary dislocation (P = 0.0005) and lower ASES (P = 0.0056) and WOSI scores (0.00132) at latest follow-up, compared to those who remained stable postsurgery.

CONCLUSION

The arthroscopic Bankart procedure has a high rate of recurrence of dislocation in Irish collision sport athletes. The current international literature suggests that the arthroscopic Bankart has similar rates of recurrence to the open procedure in collision athletes; however, this may not hold true for Irish collision sport athletes. Further research is required to determine the optimum surgical procedure for anterior shoulder instability in this population, particularly those patients with subcritical bone loss.

Surgical stabilization of pediatric anterior shoulder instability yields high recurrence rates: a systematic review

PURPOSE

The purpose of this systematic review was to assess the surgical techniques, indications outcomes and complications for pediatric patients (≤ 19 years old) undergoing shoulder stabilization procedures for anterior shoulder instability.

METHODS

The electronic databases MEDLINE, EMBASE, CINAHL, and Web of Science were searched from data inception to March 14, 2019 for articles addressing surgery for pediatric patients with anterior shoulder instability. The Methodological Index for Non-randomized Studies (MINORS) tool was used to assess the quality of included studies.

RESULTS

Overall 24 studies, with a total of 688 patients (696 shoulders) and a mean age of 16.6 ± 2.5 years met inclusion criteria. Mean follow-up was 49 ± 26 months. The majority (59%) of studies only offered shoulder stabilization procedures to patients with more than one shoulder dislocation, however, three studies reported operating on pediatric patients after first time dislocations. Of the included patients 525 had arthroscopic Bankart repair (78%), 75 had open Bankart repair (11%), 34 had modified Bristow (5%), and 26 had Latarjet (4%) procedures. The overall complication rate was 26%. Patients undergoing arthroscopic Bankart repair experienced the highest recurrence rate of 24%. There were no significant differences in recurrent instability (n.s.) or loss of external rotation (n.s.) in pediatric patients treated with arthroscopic Bankart repair compared to open Latarjet. Patients had a 95% rate of return to sport at any level (i.e. preinjury level or any level of play) postoperatively (95%).

CONCLUSIONS

Pediatric patients are at high risk of recurrent instability after surgical stabilization. The majority of pediatric patients with anterior shoulder instability were treated with arthroscopic Bankart repair. Most studies recommend surgical stabilization only after more than one dislocation. However, given the high rates of recurrence with non-operative management, it may be reasonable to perform surgery at a first-time dislocation, particularly in those with other risk factors for recurrence. With the current evidence and limited sample sizes, it is difficult to directly compare the surgical interventions and their post-operative efficacy (i.e. re-dislocation rates or range of motion). There was an overall high rate of return to sport after surgical stabilization at final follow-up.

The Bankart repair: past, present, and future

Arthur Sidney Blundell Bankart was a London-based orthopedic surgeon who discovered the essential lesion in recurrent anterior shoulder instability in 1923. He pioneered a technique, the Bankart repair, to re-establish stability to the glenohumeral joint, without sacrificing native joint motion. In this article, the original Bankart repair is compared to the modern arthroscopic Bankart repair, accompanied by a surgical video of Blundell Bankart performing the Bankart repair in 1951, shortly before his death. Bankart's original description included an open repair with a coracoid osteotomy and subscapularis tenotomy and repair. The history of the technique, its utility in present day, and the future of the Bankart repair are discussed.

Relationship Between Age at Initial Shoulder Instability and Overall Outcomes After Arthroscopic Bankart Repair: Mean 6-Year Follow-up

Background:

Age at surgery plays a crucial role in the frequency of recurrent shoulder instability. However, there are few studies that evaluate the relationship between age at initial shoulder instability and overall outcomes after stabilization surgery.

Purpose:

To compare clinical outcomes and structural changes after arthroscopic Bankart repair in patients who experienced initial shoulder instability during adolescence versus those with later onset instability.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

This study included patients who underwent arthroscopic Bankart repair at a single institution between 2007 and 2017. Comparisons were made between patients who experienced initial shoulder instability during adolescence (age 13-19 years; group A) and those with later onset instability (age 20-35 years; group B). Clinical outcomes (recurrence rate, postoperative pain, functional scores, active range of motion, and return to sports) and structural changes demonstrated by magnetic resonance imaging (MRI) were evaluated at minimum 2-year follow-up. In addition, functional outcomes within each group were compared between the patients with and without postoperative recurrence.

Results:

A total of 58 patients were included (24 patients in group A and 34 patients in group B). The mean follow-up was 72.1 months. Group A demonstrated a significantly higher recurrence rate than group B (41.7% vs 11.8%, respectively; P = .009; risk ratio, 5.36 [95% CI, 1.43-20.09]) as well as significantly lower Rowe (76.9 ± 20.1 vs 88.7 ± 13.2, respectively; P = .01) and Constant-Murley scores (92.2 ± 7.6 vs 96.3 ± 4.2, respectively; P = .01). Postoperative MRI revealed no significant structural differences between the groups regarding the glenoid labrum, glenohumeral cartilage, or osseous reaction around the implanted anchors. In group A, patients with recurrence had less satisfaction regarding postoperative sports level than those without recurrence, whereas in group B, patients with recurrence had more postoperative pain and functional impairment compared with those without recurrence.

Conclusion:

Initial shoulder instability during adolescence was associated with a higher recurrence rate and lower functional scores after arthroscopic Bankart repair compared with later onset instability, although no significant structural differences were found between the groups on MRI at a mean 6-year follow-up.

Anterior Shoulder Instability in the Professional Athlete: Return to Competition, Time to Return, and Career Length

Background:

Anterior shoulder instability is a common condition in professional athletes, yet little is known about the success of surgery. Return to competition (RTC) is a metric indicative of a successful outcome for professional athletes who undergo anterior shoulder stabilization surgery.

Purpose:

To determine the rate of RTC, time to RTC, recurrence rate, and length of career after surgery in professional athletes who had undergone surgical treatment for anterior shoulder instability.

Study Design:

Case series; Level of evidence, 4.

Methods:

We evaluated professional athletes who underwent surgical treatment for anterior shoulder instability by a single surgeon between 2007 and 2018. Data from patients’ medical records, a patient data registry, basic search engines, sports websites, and individual team websites were used to determine length of professional play before injury, duration of career after surgery, and RTC level.

Results:

Overall, 23 professional athletes (25 shoulders from 12 contact and 13 noncontact athletes) were identified. The mean age at the time of surgery was 24.3 ± 4.9 years (range, 16-35 years). Primary procedures included arthroscopic Bankart repair (76%; 19/25), open Latarjet (20%; 5/25), and bony Bankart repair (4%; 1/25). Of the 23 athletes, 22 returned to their previous level of competition (96%; 95% CI, 78%-100%). The mean time between surgery and RTC was 4.5 months (range, 3-8 months). There was no difference in time to RTC between contact and noncontact athletes (4.1 vs 4.4 months). There was no difference in RTC rates and time to return for players who received a Bankart repair versus a Latarjet procedure (4.6 vs 4.2 months). A total of 12 participants were still actively engaged in their respective sport at an average of 4.3 years since surgery, while 11 athletes went on to retire at an average of 4.8 years. Duration of play after surgery was 3.8 years for contact athletes and 5.8 years for noncontact athletes (P > .05).

Conclusion:

In this series, professional athletes who underwent surgical shoulder stabilization for the treatment of anterior glenohumeral instability returned to their presurgical levels of competition at a high rate. No differences in RTC rate or time to RTC were observed for contact versus noncontact athletes or for those who received arthroscopic Bankart repair versus open Latarjet. However, contact athletes had shorter careers after surgery than did noncontact athletes.

High Variability in Functional Outcomes and Recurrences Between Contact Sports After Arthroscopic Bankart Repair: A Comparative Study of 351 Patients With a Minimum 3-Year Follow-Up

Purpose

To compare return to sports, functional outcomes, and complications of a consecutive series of contact athletes with anterior glenohumeral instability treated with isolated arthroscopic Bankart repair for isolated anterior instability.

Methods

Between January 2008 and December 2016, 351 competitive athletes who participated in contact or collision sports underwent isolated arthroscopic Bankart repair at our institution (rugby n = 105, soccer n = 90, martial arts n = 36 boxing n = 28, field hockey n = 30, handball n = 31, and basketball n = 31). Return to sports, the Rowe score, and the Athletic Shoulder Outcome Scoring System (ASOSS) score were used to assess functional outcomes. Complications also were evaluated.

Results

The mean follow-up period was 66.7 months (range, 36-148 months) and the mean age of the 351 patients was 21.3 years (range, 17-30 years).Overall, 309 patients (88%) were able to return to sports, and 284 (81%) returned at the same level as before the injury. The mean time to return to sports was 5.3 months. The rate of return to sports, the level achieved by the patients, and time to return to sports varied significantly between sports. The Rowe and ASOSS scores showed statistical improvement after operation (P < .001). The ASOSS score varied significantly between sports (P < .001). There were 40 recurrences (11.3%), 7 complications (2%) and 21 patients (6%) underwent revision surgery. There was a significant difference in the rate of recurrences and revisions between the different contact sports.

Conclusions

In athletes with glenohumeral instability who undergo isolated arthroscopic Bankart repair for isolated anterior instability, there is great variability in the rate of return to sport at the same level, in shoulder performance after returning to competition, and in the postoperative recurrence rates. Due to the high variability found in our study, results after arthroscopic Bankart repair in contact athletes should not be reported globally by including the different sports under the "collision or contact sports" label.

The glenoid labrum: does labral lesion location matter?

Background

The glenoid labrum can be torn in 1 or more locations. It is undetermined if the location of the labral tear alters patient outcomes after repair.

Methods

A total of 252 labral repair cases were retrospectively reviewed using prospectively collected patient-ranked outcomes and examiner-determined assessments preoperatively, at 1 week, 6 weeks, 24 weeks, and at a minimum of 2 years after surgery.

Results

Preoperatively, patients who underwent a superior labral repair reported worse pain at night and during activity than patients who subsequently underwent an isolated anterior labral repair or a combined anterior and superior labral repair (P < .05). After surgery, patients who underwent an isolated superior labral repair reported more severe pain at night and during activity, increased stiffness, and less satisfaction with their shoulder than patients who had an isolated anterior (P < .05) or a combined anterior and superior labral repair (P < .05).

Conclusions

Patients with isolated superior labral repairs have more pain both before and after repair than patients who undergo anterior or anterior and superior labral repairs.

Outcome Measures After Shoulder Stabilization in the Athletic Population: A Systematic Review of Clinical and Patient-Reported Metrics

Background:

Athletic endeavor can require the “athletic shoulder” to tolerate significant load through supraphysiological range and often under considerable repetition. Outcome measures are valuable when determining an athlete’s safe return to sport. Few data are available to guide a clinician’s choice from the variety of measures available.

Purpose:

To describe the use of quantifiable objective outcome measures and patient-reported outcome tools after glenohumeral joint stabilization, specifically in an athletic population. The secondary aim of our study was to assess whether the method of measurement used was clearly described and standardized to aid clinical interpretation.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A systematic search of MEDLINE, Scopus, SPORTDiscus, and Web of Science databases was performed in December 2018 based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. After the application of selection criteria, a full review of identified papers, and screening of reference lists, a total of 62 studies were included in the review. All studies were independently appraised for quality, predefined data fields were populated and cross-checked for accuracy, and results were then summarized from these data fields.

Results:

Of the 62 included studies, 94% used a quantifiable objective clinical outcome. A majority (85%) of the studies measured range of motion, 21% recorded muscle strength, 5% measured electromyographic activity, 5% examined shoulder kinematics, and 3% assessed joint proprioception after surgery. However, only 18% of the studies clearly described a standardized method of measuring the outcome. Nearly all (95%) of the studies used at least 1 patient-reported outcome measure. The Rowe score was most commonly used (35%).

Conclusion:

We must standardize and clearly describe the use of quantifiable objective outcome measures to aid clinical interpretation. A concerted effort should also be made to standardize the use of patient-reported outcome tools after shoulder stabilization in the athletic population.

Threshold scores for treatment success after arthroscopic bankart repair using Oxford Shoulder Instability Score, Constant-Murley Score, and UCLA shoulder score

Aim

To determine the threshold score for Oxford Shoulder Instability Score (OSIS), Constant-Murley score (CMS), and University of California Los Angeles (UCLA) shoulder score that predict treatment success after arthroscopic bankart repairs.

Methods

77 patients were followed up for 12-mmonth. Threshold scores were determined by Receiver Operating Characteristic (ROC) analyses with treatment success defined as improvement in pain, no re-dislocation, expectation and satisfaction met.

Results

The follow threshold scores were identified:6-month: OSIS 35, CMS 68,UCLA 2612-month: OSIS 24, CMS 84, UCLA 33.

Conclusion

OSIS, CMS, and UCLA are good predictors of treatment success after arthroscopic bankart repair.Level of EvidenceIII.

Posterolateral Rotary Instability of the Elbow in Adolescents: A Report of 2 Cases and Review of the Literature

CASES

The authors present 2 cases of chronic posterolateral rotatory instability (PLRI) of pediatric elbows successfully treated with lateral collateral ligament (LCL) reconstruction using semitendinosus tendon allograft, including the first documented case of LCL reconstruction in the setting of an Osborne-Cotterill lesion in a pediatric patient. Full resolution of PLRI was achieved, and the patients returned to preinjury full-contact sports at 5 months postoperatively.

CONCLUSIONS

Few studies have reported LCL reconstruction in the setting of chronic PLRI in pediatric patients. The purpose of this report is to aid in the diagnosis and treatment of elbow PLRI and to describe a surgical option for recurrent PLRI in pediatric patients.

It's Not All About Redislocation: A Systematic Review of Complications After Anterior Shoulder Stabilization Surgery

BACKGROUND

The surgical treatment of recurrent shoulder instability has evolved in recent years to include a variety of soft tissue and bone block procedures, undertaken with either an open or arthroscopic approach. Although the utilization of such techniques has rapidly expanded, the associated risk of complications remains poorly defined. This information is vital for clinical decision making and patient counseling.

PURPOSE

To quantify the complication rate associated with all types of surgery for anterior glenohumeral joint dislocation.

STUDY DESIGN

Systematic review.

METHODS

A systematic search was undertaken of studies reporting complications from anterior shoulder stabilization surgery. Inclusion criteria were studies published in English between 2000 and 2017 with a minimum 2-year follow-up. Methodological quality of the included studies was assessed with the Methodological Index for Non-Randomized Studies criteria. Complication rates for all undesirable events contributing to the patient outcome were extracted and cumulative rates calculated.

RESULTS

Out of 1942 references, 56 studies were included, totaling 4362 procedures among 4336 patients. Arthroscopic soft tissue repair had a complication rate of 1.6% (n = 2805). When repair was combined with arthroscopic remplissage, the rate was 0.5% (n = 219). Open soft tissue repair had a complication rate of 6.2% (n = 219) and open labral repair with remplissage, a rate of 2.3% (n = 79). An open bone block procedure had a complication rate of 7.2% (n = 573) and an arthroscopic bone block procedure, a rate of 13.6% (n = 163).

CONCLUSION

This large systematic review demonstrates the overall complication rates (not purely recurrence rates) in modern shoulder stabilization surgery. With the growing interest in bone block stabilization procedures, including those performed arthroscopically, surgeons should be aware of the 10-fold increase in complications for these procedures over soft tissue arthroscopic surgery and counsel their patients accordingly.

Outcomes for Arthroscopic Repair of Combined Bankart/SLAP Lesions in the Treatment of Anterior Shoulder Instability: A Systematic Review and Meta-analysis

Background

Arthroscopic repair of combined Bankart/superior labral anteroposterior (SLAP) lesions is commonly performed to treat anterior shoulder instability, the clinical outcomes of which have not been widely studied.

Purpose

To compare the clinical outcomes for arthroscopic repair of combined Bankart/SLAP lesions in the treatment of anterior shoulder instability and to ascertain whether it is inferior to isolated Bankart repair.

Study Design

Systematic review; Level of evidence, 3.

Methods

A systematic review of the literature was performed through use of the MEDLINE, EMBASE, and Cochrane Library databases according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Study bias was assessed using the MINORS (Methodological Index for Non-Randomized Studies) scoring system. Randomized controlled trials, prospective or retrospective cohort studies, and case-control studies were included, whereas systematic reviews, literature reviews, conference abstracts, case reports, case series, and non-peer-reviewed studies were excluded to guarantee the quality of the study. Data on outcomes including recurrence rate, functional scores, and range of motion (ROM) were pooled, with statistical analysis performed. A P value of <.05 was considered statistically significant.

Results

The review included 7 studies with a total of 520 patients. The pooled recurrence rate after combined Bankart/SLAP repair was 6.47% (9/139). Significant improvements of postoperative versus preoperative functional scores were observed, including a reduction in the visual analog scale score for pain (mean ± SD: 0.99 ± 1.36 vs 4.13 ± 2.26; P < .00001) and an increase in mean Rowe score (89.56 ± 11.46 vs 43.16 ± 8.87; P < .00001) and mean Constant score (91.41 ± 7.57 vs 59.70 ± 5.63; P < .00001). In terms of ROM, no reduction was found in external rotation (66.56° ± 13.33° vs 67.22° ± 14.27°; P = .21), and a significant increase in abduction was found (157.67° ± 4.11° vs 144.18° ± 8.28°; P < .00001). No statistically significant difference was found between arthroscopic repair of combined Bankart/SLAP lesions and isolated Bankart repair regarding recurrence rate, functional scores, or ROM.

Conclusion

Of the pooled data, patients who underwent arthroscopic repair of combined Bankart/SLAP lesions in treatment of anterior shoulder instability showed a low recurrence rate, favorable functional scores, and no significant restriction on ROM, all of which were not significantly worse than outcomes of isolated Bankart repair. Therefore, combined repair was proven to be a viable option for extensive labral lesions.

Variability of Reporting Recurrence After Arthroscopic Bankart Repair: A Call for a Standardized Study Design

Background

High recurrence rates have been reported after anterior shoulder dislocations, regardless of the treatment utilized. However, the definition of recurrent instability has been inconsistent, making a comparison between studies difficult.

Purpose

To report on the nature with which the rate of recurrent instability is reported after arthroscopic Bankart repair, across all levels of evidence, and to analyze factors that may affect the reported rate of recurrence.

Study Design

Systematic review; Level of evidence, 4.

Methods

A systematic review of the literature was performed by searching PubMed, the Cochrane Central Register of Controlled Trials, Embase, and ClinicalTrials.gov for studies published within the dates of January 2008 and September 2018. Studies in English that reported on the recurrence of instability after arthroscopic Bankart repair for anterior shoulder instability were considered for inclusion in this review. A meta-regression was performed to test for a linear association between the reported recurrence rate and several continuous covariates, including mean age at surgery, mean length of follow-up, attrition rate (loss to follow-up percentage), and percentage of male patients.

Results

A trim-and-fill meta-analysis yielded an estimated overall recurrence rate of 17.4% (95% CI, 14.3%-20.9%). There was a significant difference in the recurrence rate depending on the level of evidence (Q(3) = 10.98; P = .012). Significant associations were found with the recurrence rate through the meta-regression, including a negative association with mean age (P = .009), a positive association with mean follow-up time (P = .002), and a positive association with attrition rate (P = .035).

Conclusion

A call for standardization is necessary for reporting outcomes of anterior instability after arthroscopic Bankart repair, especially with regard to the reporting of recurrence/failure rates, with careful consideration of the effects that may occur from patient demographics and study design. With no current recommendations for deeming failure, we suggest that all forms of instability be accounted for when determining a failed treatment procedure, with future studies placing an emphasis on greater control of the study design.

Clinical Outcomes After Anterior Shoulder Stabilization in Overhead Athletes: An Analysis of the MOON Shoulder Instability Consortium

BACKGROUND

Traumatic anterior shoulder instability is a common condition affecting sports participation among young athletes. Clinical outcomes after surgical management may vary according to patient activity level and sport involvement. Overhead athletes may experience a higher rate of recurrent instability and difficulty returning to sport postoperatively with limited previous literature to guide treatment.

PURPOSE

To report the clinical outcomes of patients undergoing primary arthroscopic anterior shoulder stabilization within the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability Consortium and to identify prognostic factors associated with successful return to sport at 2 years postoperatively.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Overhead athletes undergoing primary arthroscopic anterior shoulder stabilization as part of the MOON Shoulder Instability Consortium were identified for analysis. Primary outcomes included the rate of recurrent instability, defined as any patient reporting recurrent dislocation or reoperation attributed to persistent instability, and return to sport at 2 years postoperatively. Secondary outcomes included the Western Ontario Shoulder Instability Index and Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow questionnaire score. Univariate regression analysis was performed to identify patient and surgical factors predictive of return to sport at short-term follow-up.

RESULTS

A total of 49 athletes were identified for inclusion. At 2-year follow-up, 31 (63%) athletes reported returning to sport. Of those returning to sport, 22 athletes (45% of the study population) were able to return to their previous levels of competition (nonrefereed, refereed, or professional) in at least 1 overhead sport. Two patients (4.1%) underwent revision stabilization, although 14 (28.6%) reported subjective apprehension or looseness. Age ( P = .87), sex ( P = .82), and baseline level of competition ( P = .37) were not predictive of return to sport. No difference in range of motion in all planes ( P > .05) and Western Ontario Shoulder Instability Index scores (78.0 vs 80.1, P = .73) was noted between those who reported returning to sport and those who did not.

CONCLUSION

Primary arthroscopic anterior shoulder stabilization in overhead athletes is associated with a low rate of recurrent stabilization surgery. Return to overhead athletics at short-term follow-up is lower than that previously reported for the general athletic population.

Driving after Upper or Lower Extremity Orthopaedic Surgery

Orthopaedic procedures can affect patients' ability to perform activities of daily living, such as driving automobiles or other vehicles that require coordinated use of the upper and lower extremities. Many variables affect the time needed before a patient can drive competently after undergoing orthopaedic surgery to the extremities. These variables include whether the patient underwent upper or lower extremity surgery, the country in which the patient resides, whether the right or left lower extremity is involved, whether the dominant arm is involved, whether the extremity is in a cast or brace, whether the patient has adequate strength to control the steering wheel, and whether the patient is taking pain medication. The type and complexity of the procedure also influence the speed of return of driving ability. Few studies provide definitive data on driving ability after upper or lower extremity surgery. Patients should be counseled not to drive until they can control the steering wheel and the pedals competently and can drive well enough to prevent further harm to themselves or to others. This review discusses the limited recommendations in the literature regarding driving motorized vehicles after upper or lower extremity orthopaedic surgery.

High rate of return to sport in adolescent athletes following anterior shoulder stabilisation: a systematic review

Importance

Traumatic anterior shoulder instability remains common for the adolescent athletes.

Aim or objective

To perform a systematic review on the outcomes and return to sport (RTS) following Bankart repair in adolescent athletes.

Evidence review

A systematic review using the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines was conducted of studies reporting outcomes following open and/or arthroscopic Bankart repair using modern suture anchors following traumatic anterior shoulder dislocations in adolescent patients (ages 10-19 years). Quality assessment was evaluated with ROBINS-I and MINORS instruments. The outcomes analysed included RTS, timetable to unrestricted activity, recurrent instability and revision surgery.

Findings

This systematic review identified 11 studies comprising 461 adolescent athletes with a mean age of 15.7 years (range, 11-19 years) and an average follow-up of 48.8 months (range, 22-85.2 months). A total of 392 patients (400 shoulders) underwent arthroscopic Bankart repair, while the remaining 69 patients (69 shoulders) underwent an open procedure. The average MINORS score was 9.6 for non-comparative studies and 17 for comparative studies. ROBINS-I revealed six studies to have a moderate risk of bias, while the remaining five studies presented serious risk of bias. There was an overall 81.5% rate of RTS to preinjury levels of athletic competition at an average of 5.3 months following Bankart repair for traumatic anterior shoulder instability. The overall total mean incidence of recurrent instability was 18.5%, while the mean incidence of revision surgery was 12.1%. Contact athletes had a 31.1% and 13% rate of recurrence and revision surgery, respectively. In comparison, collision athletes were shown to have a 10.4% and 1.4% incidence of recurrent instability and revision surgery, respectively.

Conclusions and relevance

Adolescent athletes who undergo Bankart repair for traumatic anterior shoulder instability have an 81.5% rate of RTS to preinjury levels of play at an average of 5 months following surgery. The overall total mean incidence of recurrent instability in the adolescent population is 18.5%, while the mean incidence of revision surgery is 12.1%. The results of anterior shoulder stabilisation in contact athletes is much less predictable, with higher reported rates of recurrent instability and revision surgery.

Recurrence After Arthroscopic Labral Repair for Traumatic Anterior Instability in Adolescent Rugby and Contact Athletes

BACKGROUND

Traumatic glenohumeral dislocation of the shoulder is one of the most common shoulder injuries, especially among adolescent athletes. The treatment of instability for young athletes continues to be controversial owing to high recurrence rates.

PURPOSE

To investigate the recurrence rate of shoulder instability after arthroscopic capsulolabral repair for adolescent contact and collision athletes.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Sixty-seven patients aged <18 years underwent an arthroscopic labral repair over a 5-year period. The mean ± SD age of the cohort was 16.3 ± 0.9 years (range, 14-17 years) and consisted of 1 female and 66 males. All patients were contact athletes, with 62 of 67 playing rugby. Demographic, clinical, and intraoperative data for all patients with shoulder instability were recorded in our database. Recurrence rates were recorded and relative risks calculated.

RESULTS

At a follow-up of 33 ± 20 months, 34 of 67 patients had recurrent instability for an overall recurrence rate of 51% among adolescent contact athletes after arthroscopic labral repair surgery. The mean time to recurrence was 68.1 ± 45.3 weeks. All recurrences occurred as a result of a further sporting injury. Relative risk analysis demonstrated that athletes aged <16 years had 2.2 (95% CI, 1.2-2.1) times the risk of developing a further instability episode as compared with athletes aged ≥16 years at the time of index surgery ( P = .0002). The recurrence rate among adolescent athletes after bony Bankart repairs was 57.9% versus 47.9% for soft tissue labral repairs ( P = .4698). The incidence of Hill-Sachs lesions ( P = .0002) and bony Bankart lesions ( P = .009) among adolescent athletes was significantly higher than among adult controls ( P = .002). The presence of bone loss did not lead to a significant increase in recurrence rate over and above the effect of age.

CONCLUSION

Adolescent contact athletes undergoing arthroscopic labral repair have an overall recurrence rate of 51%. Rugby players who undergo primary arthroscopic shoulder stabilization aged <16 years have 2.2 times the risk of developing a further instability episode when compared with athletes aged ≥16 years at the time of index surgery, with a recurrence rate of 93%.

Variability of Outcome Reporting Following Arthroscopic Bankart Repair in Adolescent Athletes: A Systematic Review

PURPOSE

To conduct a systematic review of the literature to assess the variability of the reporting of outcome measures after arthroscopic Bankart repair for traumatic anterior shoulder instability in the adolescent population.

METHODS

A systematic review was conducted investigating all studies reporting outcomes after arthroscopic Bankart repair in the adolescent population. Four databases (Medline, EMBASE, Ovid, and Google Scholar) were screened for clinical studies involving the arthroscopic management of anterior shoulder instability in adolescents. A full-text review of eligible studies was conducted. Inclusion and exclusion criteria were applied to the searched studies. A quality assessment was completed for each included study using the Methodological Index for Nonrandomized Studies instrument and the Center for Evidence-Based Medicine's Levels of Evidence Scale.

RESULTS

We identified 8 eligible studies involving 274 patients (282 shoulders). There was considerable variation with regard to reported outcomes after arthroscopic Bankart repair for anterior shoulder instability in the adolescent population. The most common patient-reported outcomes included the Rowe Score (50%), Single Assessment Numeric Evaluation (37.5%), American Shoulder and Elbow Surgeons Shoulder Outcome Score (25%), and the Constant Score (25%). Clinical outcomes reported included recurrence (100%), return to sport (62.5%), patient satisfaction (37.5%), stability (37.5%), pain scores (37.5%), and range of motion (12.5%).

CONCLUSIONS

There is considerable variation in reported clinical outcome measurements after arthroscopic Bankart repair for traumatic shoulder instability in the adolescent population. This study supports the need for standardized outcome reporting after arthroscopic anterior shoulder instability surgery in adolescents.

What's New in Pediatric Upper Extremity Sports Injuries?

BACKGROUND

Sports injuries are common in pediatric and adolescent patients and the evaluation and treatment of these injuries continues to evolve. The purpose of this review is to provide a comprehensive appraisal of the most recent literature, highlighting updates on sports-related upper extremity injuries in pediatric patients.

METHODS

An electronic search of the PubMed, EMBASE, and Google Scholar databases was performed for keywords related to pediatric overhead athletes, osteochondritis dissecans (OCD) of the capitellum, medial epicondyle fractures, shoulder instability, and clavicle fractures. Search results were filtered by publication date to yield articles published electronically or in print on or after January 1, 2013 to May 30, 2017. Papers were selected based on expert opinion and consensus by the authors and included if deemed to have contributed important findings to the above topics.

RESULTS

A total of 51 articles were deemed to have contributed significant findings to the literature: 11 overhead athlete, 9 OCD of the capitellum, 6 medial epicondyle fractures, 17 shoulder instability, and 8 clavicle fractures. The level of evidence for most studies was either Level III or IV.

CONCLUSIONS

Overuse and traumatic conditions of the pediatric elbow including UCL tear, capitellar OCD, and medial epicondyle fractures represent a significant portion of injuries in the overhead athlete. Research in the prevention and treatment of primary and recurrent shoulder instability in young athletes continues to evolve. The operative treatment of clavicle fractures in adolescents has been increasing without a commensurate increase in the level of evidence supporting such treatment. Advances have been made in the treatment of sports-related upper extremity injuries in pediatric patients, however, high-level, comparative outcomes research in many areas is lacking and this review may help inform topics for future study.

Level IV-Literature review.

Return to Sports After Shoulder Stabilization Surgery for Anterior Shoulder Instability

PURPOSE OF REVIEW

Young athletes continue to experience traumatic shoulder instability and are often plagued by recurrent instability, limiting their return to sport. The purpose of this paper was to review return to sport in athletes after shoulder stabilization surgery for anterior shoulder instability.

RECENT FINDINGS

Athletes managed nonoperatively demonstrate unacceptably high rates of recurrent instability and are less likely to successfully return to sport. Operative management includes capsuloligamentous repair (arthroscopic versus open) and bone augmentation techniques. While modern arthroscopic techniques have provided favorable outcomes, open techniques have demonstrated lower recurrence rates among young collision athletes. A subset of athletes continue to experience recurrent instability, leading to further investigation of concomitant pathologies, which may put patients at risk of failure following Bankart repair. Bony augmentation procedures remain favorable for patients with glenoid bone loss; however, what constitutes critical bone loss in the decision between anterior labral repair versus bone augmentation has recently been questioned. Operative management of anterior shoulder instability provides superior results, including lower recurrent instability and return to sport. Future research on patient-specific risk factors may aid surgical decision-making and optimization of outcomes.
