Arthroscopic Bankart repair with knotless suture anchors: A comparison of the permanent and absorbable types

Aim:The aim of this study was to compare the clinical outcomes of arthroscopic Bankart repair (ABR) using two types of knotless suture anchors (KSAs) in patients with post-traumatic recurrent anterior glenohumeral instability (AGHI).Methods:Thirty-two patients underwent an ABR using KSAs: a permanent KSA (PushLock) and an absorbable counterpart (BioKnotless). There were 16 patients in each group. Pre-and post-operative assessment for shoulder function using the American Shoulder and Elbow Surgeons and Constant–Murley scores, recurrence of instability, post-operative limitation of external rotation (ER) and ability to return to pre-injury level were recorded in both groups.Results:Both groups displayed significant improvements in functional scores ( p < 0.0001) without a significant difference between the groups. Of the 32 patients, 9.4% had recurrence of instability (one re-dislocation in group 1 and two symptomatic subluxations in group 2). Return to pre-injury level occurred in 87.5% and 81.3% of group 1 and group 2, respectively. There was 2° to 3° loss of ER after ABR in both groups; the difference between the groups was not significant ( p = 0.45).Conclusion:ABR for recurrent AGHI using a permanent or absorbable KSA offers comparable successful outcomes; no significant statistical difference was found.

Arthroscopic Bankart Repair

Anterior glenohumeral instability is among the most common conditions requiring orthopaedic care, particularly in the athletic population. The evaluation and management of anterior instability is dependent on many factors and a thorough understanding of each component of the patient's instability is necessary to achieve an optimal outcome. Patient factors including age, activity level, sport and number of instability events must be considered along with examination and imaging findings. A variety of treatment options, both surgical and nonsurgical, exist to manage anterior instability, however, selecting the optimal surgical treatment is not always simple. This review will discuss the role of the arthroscopic Bankart repair in the surgical management of anterior glenohumeral instability. The preoperative evaluation, surgical techniques, outcomes, and complications will be discussed in the context of the available literature validating this approach to surgical stabilization. The outcomes of arthroscopic Bankart repair will be reviewed including recurrent instability, return to sport and patient reported outcome measures to illustrate the appropriate application of this technique.

Functional outcome of arthroscopic Bankart repair for anterior shoulder instability based on suture anchor configuration

<p class="abstract"><strong>Background:</strong> The objective of the study was to evaluate the functional outcome of arthroscopic Bankart repair for anterior shoulder instability to assess whether the number and position of suture anchors plays a role in determining the functional outcome.</p><p class="abstract"><strong>Methods:</strong> This was a prospective study on 32 patients operated with arthroscopic Bankart repair between December 2017 to April 2019.

Results of Arthroscopic Bankart Repair in Recreational Athletes and Laborers: A Retrospective Study With 5 to 14 Years of Follow-up.

Background:Arthroscopic Bankart repair is the most common procedure for anterior shoulder instability management. However, the long-term efficacy of the procedure is questionable, and the results are different among different populations. Few studies have focused on specific populations, such as recreational athletes and laborers.Hypothesis:Good to excellent long-term results, with a low recurrence rate, can be achieved using arthroscopic Bankart repair in recreational athletes and laborers suffering from anterior shoulder instability.Study Design:Case series; Level of evidence, 4.Methods:A specific group of laborers and recreational athletes were included in this study. A total of 52 patients (52 shoulders) with anterior-inferior traumatic shoulder instability underwent arthroscopic Bankart repair and met our strict criteria for study inclusion. The recurrence rate was recorded. Patients were evaluated at a minimum follow-up of 5 years using the American Shoulder and Elbow Surgeons (ASES) score, the Rowe score, the Constant score, and a visual analog scale (VAS) for pain. A radiological evaluation for arthritis was also performed according to the Samilson-Prieto classification.Results:The mean follow-up was 105.4 months (range, 65-164 months). Our overall recurrence rate was 11.5% (6/52 patients). All patients were able to return to their previous job status with minimum limitations, and 76.7% of our study population reported returning to their preinjury sporting activities. Postoperatively, all scores were improved, with statistically significant increases from preoperative values (P < .001). At the last radiographic follow-up, 9 patients (18.8%) had mild arthritis, while 2 patients (4.2%) had moderate arthritis.Conclusion:Arthroscopic soft tissue Bankart repair may provide good to excellent long-term clinical results with an acceptable recurrence rate in medium-demand patients (recreational athletes and laborers).

Arthroscopic Bankart repair following traumatic recurrent shoulder dislocation: A prospective review of 30 cases.

Literature on outcomes of arthroscopic Bankart repair at the intervening time intervals in traumatic recurrent dislocation of shoulder joint is limited. Case series. A prospective review of 30 shoulders, aged 20-40 years with clinically and magnetic resonance imaging established findings that were treated with primary arthroscopic Bankart repair and followed up for a minimum of 2 years. Outcomes were evaluated using Rowe score and University of California at Los Angeles (UCLA) scoring system. The mean age was 26.40 years. All patients had definite trauma history. Average number of dislocation was 13.77 + 18.435 (range: 3-100). Time duration from first dislocation to surgery was an average of 4.80 + 3.576 years. The average size of the lesion was approximately 31% of the glenoid circumference. The number of suture anchors used for fixation did not correlate significantly with any of the scores. The mean Rowe and UCLA scores were 94.16 ± 9.7 and 33.83 ± 3.32, respectively, at final follow-up. The average duration of hospital stay was 7 days. Of the 30 patients, 2 (6.66%) had dislocation events post-operatively. Returns to pre-injury level were available for 27 (90%) of 30 patients. Multivariate analysis of independent Variables: age; side and number of dislocations, time to surgery, duration of surgery, size of lesion, number of anchors, and concurrent Hill-Sachs lesion, shown to have no significant relationship to outcomes. Arthroscopic Bankart repair is an effective and safe technique for treating anterior glenohumeral instability in patients with recurrent traumatic shoulder dislocation.

Long-term clinical outcome of arthroscopic Bankart repair with suture anchors

The most common surgical technique in traumatic anterior shoulder instability is the arthroscopic Bankart repair, which has excellent short-term results. The long-term results of the arthroscopic Bankart repair are less frequently studied, with a high recurrence rate of 23% to 35%. The aim of this study was to evaluate the medium-term to long-term results of arthroscopic Bankart repair using suture anchors and to identify specific risk factors for recurrent instability. Included were 147 patients after traumatic anterior shoulder dislocation who underwent an arthroscopic Bankart repair. The primary outcome was recurrent instability, defined as dislocation or subluxation as perceived by the patients. The secondary outcome was subjective shoulder stability and function as well as quality of life, evaluated using the Western Ontario Shoulder Instability Index, the Simple Shoulder Test, and the 12-Item Short Form Health Survey. Prognostic factors for recurrent instability were analyzed. Recurrent instability occurred in 22% of patients with a mean follow-up of 6.3 years. Survival at 5 and 10 years without recurrent instability was 79% and 78%, respectively (95% confidence interval, 72%-85% and 71%-85%, respectively). The Western Ontario Shoulder Instability Index score, the Simple Shoulder Test score, and the 12-item Short Form Physical Component Summary improved significantly in the nonrecurrence group (P < .001, P = .004, and P = .002, respectively). Younger age and use of fewer than 3 anchors were associated with a higher risk of recurrent dislocation (P = .008 and P = .039, respectively). We found an overall recurrent instability rate of 22% (dislocation or subluxation). Good long-term results were observed after arthroscopic Bankart repair in patients older than 20 years with 3 or more suture anchors used.

Does creating a trough on the anterior glenoid rim make a difference in Arthroscopic Bankart repair using suture anchors? A mid-term follow-up retrospective study

PurposeCreating a trough on the anterior glenoid rim is one of the methods used for arthroscopic Bankart repair with suture anchors. The purpose of this study was to analyze clinical and radiological outcomes of arthroscopic Bankart repair with suture anchors; to compare between the outcomes of surgical procedures with and without trough. MethodsClinical and radiological outcomes were evaluated for 116 patients who underwent arthroscopic Bankart repair at our institute from 2005 to 2011. The mean follow-up was 5.2 years (range, 2–8.8 years). All data were divided into trough group (n = 62) and non-trough group (n = 71). Clinical and functional outcomes were assessed pre- and postoperatively as range of motion (ROM), pain on the visual analog scale (p-VAS), function on the visual analog scale (f-VAS), and Rowe score. Radiological outcomes were also evaluated. ResultsThe overall postoperative clinical and functional outcomes improved significantly (P < .001). A total of 8 patients (6.8%) showed recurrent instability. Radiologic findings showed mild arthritis in 27 cases (23.1%), moderate arthritis in 6 cases (5.1%), and no severe arthritis. 32 patients showed anterior apprehension after surgery, and 22 out of those 32 patients were from non-trough group. However, no significant difference between the trough and non-trough groups was found with respect to clinical and functional outcomes (P > .05). ConclusionThe additional procedure of creating a trough did not improve clinical outcomes in terms of frank dislocation; however, at the final follow-up, patients with the trough showed less anterior apprehension. Overall, arthroscopic Bankart repair using suture anchors had relatively good clinical outcome, with a redislocation rate of 6.8%. Level of evidenceLevel III, Case series.

Meta-Analysis of Randomized Controlled Trials Involving Anterior Shoulder Instability.

Background:Arthroscopic repair is gaining popularity over open repair for the treatment of bankart lesions. The study aims to evaluate the outcome of arthroscopic repair with open repair in randomised controlled trials conducted comparing the two techniques.Methods:We searched the Cochrane library, PubMed and EMBASE up to December 2017 for clinical trials comparing the outcomes of arthroscopic bankart repair with open bankart repair. We used fixed or random effects model depending upon heterogenicity. Dichotomous variables were presented as Risk Ratios (RRs) with 95% Confidence Intervals (CIs), and continuous data were measured as measured differences with 95% CIs.Result:Five studies were included, with sample size ranging from 42 to 196. Fixed effect analysis showed that the shoulder was more stable in open repair (RR=0.897, 95% CI: 0.821 to 0.980, P= 0.94) but the loss of external rotation at shoulder joint was also higher in those had open repair (RR=0.325, SMD=-0.411, 95% CI: -1.229 to 0.407). The functional outcome assessed by Rowe score was better in open repair (P=0.325). The operative time was lesser in arthroscopic repair but was not statistically significant (P=0.085).Conclusion:Our meta-analysis showed that the use of arthroscopic repair though offers better shoulder movement but the open repair is superior in terms of shoulder stability.

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

To review the outcomes of arthroscopic Bankart repair for anterior shoulder instability in an adolescent population participating in collision and contact sports. A retrospective review of 39 shoulders in 37 adolescent (≤ 19 years) athletes who underwent primary arthroscopic Bankart repair using suture anchors with at least 2-year follow-up. All patients had a history of trauma to their shoulder resulting in an anterior dislocation. Outcome measures included patient satisfaction, the visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES), and Rowe scores. Recurrence of dislocation, and return to sporting activity were also assessed. The average age at the time of surgery was 16.9 years (range, 15-19 years), and the average follow-up was 6.4 years (range, 4.3-10.0 years). 58.6% of patients participated in collision sports. Time to surgery after the initial dislocation episode was 9.2 months (range, 0.5-36.2 months). Four shoulders (10.3%) had dislocation events postoperatively. 78.1% of patients returned to sports at the same level of competition. Average VAS was 0.49 ± 1.01 and the average ASES and Rowe scores were 92.8 ± 12.59 and 85.0 ± 24.19, respectively. Univariate analyses demonstrated that subjective functional outcomes were negatively correlated with recurrence (ASES, P = 0.005; Rowe, P = 0.001) and failure to return to sport (ASES, P = 0.016; Rowe, P = 0.004). Independent variables shown to have no significant relationship to functional outcomes included age, follow-up, number of preoperative dislocations, time to surgery, sport classification, competition level, tear extent, number of anchors, concurrent Hill-Sachs lesions, and repair of a SLAP lesion. Arthroscopic Bankart repair is an effective surgical option for traumatic shoulder instability in adolescents participating in collision and contact sports. At a minimum of 4-year follow-up, arthroscopic Bankart repair effectively restored stability in 90% of cases; 80% returned to their preinjury level of sport.

Long-term results of arthroscopic Bankart repair: Minimum 10years of follow-up.

This study investigated the long-term results of arthroscopic Bankart repair in terms of rates and timelines of recurrence of instability, with special interest in young adult patients aged ≤20years. Between 2000 and 2005, 186 shoulders [182 patients, 50 women, median age 26 (range 15-58) years] were operated on at a university hospital using arthroscopic Bankart repair because of instability after traumatic anteroinferior shoulder dislocation. Medical records were retrospectively reviewed and patients were assessed using postal questionnaires or telephone interview after a minimum of 10years of follow-up [median 12.2 (range 10-16) years]. The primary outcome measure was recurrence of instability (assessed from 167 shoulders), other outcome measures included Oxford instability score (OIS), subjective shoulder value (SSV), and Western Ontario instability index (WOSI) (assessed from 157 shoulders). At the end of follow-up, 50/167 shoulders (30%) had recurrence of instability and 30/167 (18%) were subjected to reoperation due to instability symptoms. Twenty-six (52%) failures occurred within ≤2years, 11 (22%) within 2-5years, and 13 (26%) >5years after surgery. Failure rate was 19/35 (54%) for patients aged ≤20years and 31/132 (24%) for patients aged >20years; reoperation rates were 11/35 (31%) and 19/132 (14%), respectively. Mean OIS was 20 (SD 9, range 12-50), SSV 83% (SD 21, range 10-100), and WOSI score 80 (SD 22, range 33-100). Nearly one-third of patients had recurrence of instability after arthroscopic Bankart repair after a minimum of 10-year follow-up. Patients aged ≤20years did poorly with more than half of the patients having recurrence; alternative stabilization techniques should probably be considered for these patients. IV.

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

Background:Literature on arthroscopic stabilization in adolescent patients participating in collision and contact sports is limited, as most studies include adolescents within a larger sample group comprised primarily of adults.Purpose:To review the outcomes of arthroscopic Bankart repair for anterior shoulder instability in an adolescent population participating in collision and contact sports.Study Design:Case series; Level of evidence, 4.Methods:This retrospective review included 39 shoulders in 37 adolescent (≤19 years) athletes who underwent primary arthroscopic Bankart repair using suture anchors with at least 2-year follow-up. All patients had a history of trauma to their shoulder resulting in an anterior dislocation. Outcome measures included patient satisfaction, the visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score. Recurrence of dislocation and return to sporting activity were also assessed.Results:The mean age at the time of surgery was 16.9 years (range, 15-19 years), and the mean follow-up was 6.3 years (range, 4.3-10.0 years); 58.6% of patients participated in collision sports. Time to surgery after the initial dislocation episode was 9.2 months (range, 0.5-36.2 months). Four shoulders (10.3%) had dislocation events postoperatively. The majority (78.1%) of patients returned to sports at the same level of competition. Mean VAS was 0.49 ± 1.0, and the mean ASES and Rowe scores were 92.8 ± 12.6 and 85.0 ± 24.2, respectively. Univariate analyses demonstrated that subjective functional outcomes were negatively correlated with recurrence (ASES, P = .005; Rowe, P = .001) and failure to return to sport (ASES, P = .016; Rowe, P = .004). Independent variables shown to have no significant relationship to functional outcomes included age, follow-up, number of preoperative dislocations, time to surgery, sport classification, competition level, tear extent, number of anchors, concurrent Hill-Sachs lesion, and repair of a superior labral anterior-posterior (SLAP) lesion.Conclusion:Arthroscopic Bankart repair is an effective surgical option for traumatic shoulder instability in adolescents participating in collision and contact sports. At a minimum 4-year follow-up, arthroscopic Bankart repair effectively restored stability in 90% of cases; 80% returned to their preinjury level of sport.

Clinical Outcome of Arthroscopic Bankart Repair Combined With Simultaneous Capsular Repair

Background: A capsular tear and humeral avulsion of the glenohumeral ligament lesion are not uncommon findings in association with a Bankart lesion. However, there have been few reports regarding the prevalence of such capsular lesions and the postoperative recurrence after capsular repair. Purpose/Hypothesis: This study investigated the prevalence of capsular lesions and clarified their influence on the postoperative recurrence of instability. In addition, factors were identified that were associated with the occurrence of capsular lesions and the postoperative recurrence of instability. We hypothesized that clinical outcomes would be improved by combining arthroscopic Bankart repair with simultaneous capsular repair. Study Design: Cohort study; Level of evidence, 3. Methods: Capsular lesions were retrospectively examined through operative records, still pictures, and videos in 172 shoulders with traumatic anterior instability. First, the prevalence of capsular lesions and their severity were investigated. Then, postoperative recurrence was determined in shoulders observed for a minimum of 2 years. Finally, factors were assessed that were associated with the occurrence of capsular lesions and the postoperative recurrence of instability. Results: A capsular lesion was recognized in 37 shoulders (21.5%), being severe and mild in 20 and 17, respectively. All were repaired simultaneously with the arthroscopic Bankart procedure. After follow-up for at least 2 years, recurrence of instability was detected in 10 of 34 shoulders (29.4%), including 6 (31.6%) with severe capsular lesions and 4 (26.7%) with mild lesions. The recurrence rate was significantly higher in shoulders with a capsular lesion than in shoulders without a capsular lesion (18 of 120, 15%; P = .013), but there was no significant difference between severe and mild lesions. Regardless of the sport played, capsular lesions were significantly more frequent in patients ≥30 years old, patients with complete dislocation, and patients with a coexisting Hill-Sachs lesion. Postoperative recurrence of instability was significantly more frequent in patients <30 years and competitive athletes. Conclusion: In shoulders undergoing arthroscopic Bankart repair, capsular lesions were often present and were associated with higher postoperative recurrence of instability. While these lesions were more frequent in older patients, postoperative recurrence of instability was more likely in young competitive athletes.

Results of Arthroscopic Bankart Repair for Anterior-Inferior Shoulder Instability at 13-Year Follow-up

Background: Anterior-inferior shoulder instability is a common injury in young patients, particularly those practicing overhead-throwing sports. Long-term results after open procedures are well studied and evaluated. However, the long-term results after arthroscopic repair and risk factors of recurrence require further assessment. Hypothesis: Arthroscopic Bankart repair results are comparable with those of open repair as described in the literature. Study Design: Case series; Level of evidence, 4. Methods: A total of 180 shoulders with anterior-inferior shoulder instability were stabilized arthroscopically, met the inclusion criteria and the patients were able to be contacted at a minimum of 10-year follow-up. Of these patients, 143 agreed to participate in the study. Assessment was performed clinically in 104 patients using the American Shoulder and Elbow Surgeons score, Constant score, American Academy of Orthopaedic Surgeons score, Rowe score, and the Dawson 12-item questionnaire. The Samilson-Prieto score was used to assess degenerative arthropathy in radiographs available for 100 shoulders. Additionally, 15 patients participated through a specific questionnaire and 24 patients through a telephone survey. Results: The overall redislocation rate was 18.18%. Redislocation rates for the different types of fixation devices were as follows: FASTak/Bio-FASTak, 15.1% (17/112); SureTac, 26.3% (5/19); and Panalok, 33.3% (4/12). Concomitant superior labral anterior-posterior repair had no effect on clinical outcome. Redislocation rate was significantly affected by the patient’s age and duration of postoperative rehabilitation. Redislocation rate tended to be higher if there had been more than 1 dislocation preoperatively (P = .098). Severe dislocation arthropathy was observed in 12% of patients, and degenerative changes were significantly correlated with the number of preoperative dislocations, patient age, and number of anchors. The patient satisfaction rate was 92.3%, and return to the preinjury sport level was possible in 49.5%. Conclusion: Clinical outcome at a mean follow-up of 13 years after arthroscopic repair of anterior-inferior shoulder instability is comparable with the reported results of open Bankart repair in the literature and allows management of concomitant lesions arthroscopically. Modifiable risk factors of postoperative redislocation and arthropathy must be considered. Stabilization after the first-time dislocation achieves better clinical and radiological outcomes than after multiple dislocations.

Mid-term results of arthroscopic Bankart repair: A review of 31 cases

IntroductionThe goal of this study was to assess the overall function (Walch-Duplay score), stability, time and because it is time of return to sport and level of return to sport, and satisfaction of patients who underwent an arthroscopic Bankart repair for chronic anterior shoulder instability at 5 years’ follow-up. In addition, the potential correlation between the postoperative Walch-Duplay score and the presence of risk factors for recurrence, the ISIS score, associated labral lesions discovered intraoperatively and clinical presentation was determined. Material and methodsThis was a retrospective, single-centre study of 30 patients (31 arthroscopic Bankart procedures) operated between January 2003 and December 2012. The Walch-Duplay score, recurrence rate (dislocation or subluxation), return to sports and subjective satisfaction were evaluated. ResultsThe mean postoperative Duplay score was 77.4 points (100–15)±30.6. At review, 25.8% of patients had recurrence of the preoperative symptoms, including 16.1% glenohumeral dislocation and 9.7% subluxation. Patients requiring revision surgery (Bristow-Latarjet procedure) had no additional instability episodes. Among the athletes, 16 (66.6%) returned to their pre-injury level, four (16.6%) changed to a different sport and four stopped participating (16.6%). The subjective evaluation of the procedure was satisfactory in 75% of cases. No risk factors for recurrence were significantly related to the Walch-Duplay score. ConclusionDespite satisfactory Walch-Duplay scores and subjective results, this mid-term follow-up study revealed a significant number of patients with recurrent instability after arthroscopic Bankart repair, confirming published data. Careful patient selection is essential prior to proposing this procedure and patients should be informed of the potential risk of revision surgery. Level of evidenceLevel IV, retrospective study.

Arthroscopic Bankart repair for recurrent shoulder instability: A retrospective study of 86 cases

The purpose of our study was to retrospectively evaluate the outcomes of arthroscopic Bankart repair in 86 patients, who met the inclusion criteria of at least one episode of shoulder dislocation, with a minimum follow-up of one year. Outcome was measured by the use of Western Ontario Shoulder Instability (WOSI) score.At the end of our study, the recurrence rate was 7%. Young age (p=0.016) and ligamentous laxity (p=0.003) were associated with recurrence.Arthroscopic Bankart repair is a reliable treatment method, with good clinical outcomes. Patients with younger age or with ligamentous laxity were at the greatest risk of recurrence.

Résultats de l’intervention de Bankart chez les sportifs de contact versus non contact

BackgroundThe clinical results of arthroscopic Bankart repair for contact athletes varies according to published reports. The purposes of this study were to analyze the clinical outcome of open or arthroscopic Bankart repair and to investigate the results in contact and non-contact athletes. HypothesisClinical outcome of arthroscopic Bankart repair is similar to that of open procedure. Patients and methodsOne hundred patients with recurrent anterior shoulder dislocation without a large bony defect were retrospectively reviewed. Fifty-one contact and 49 non-contact athletes were found with a mean follow-up of 17 months. Forty-nine shoulders underwent arthroscopic Bankart repairs; 51 shoulders had open Bankart repairs. ResultsIn non-contact athletes, there was a 5% (1/22 cases) recurrence rate in the open group and 4% (1/27 cases) in the arthroscopic group. In contrast, in contact athletes, there was a 10% (3/29 cases) recurrence rate in the open group and 14% (3/22 cases) in the arthroscopic group. There was no significant difference in the recurrence rate between contact and non-contact athletes, although contact athletes showed two to three times a higher recurrence rate than that of non-contact athletes. The Rowe score and Constant score showed no significant difference between the two procedures and between the contact and non-contact athletes. The rate of the complete return to sports showed no significant difference between contact and non-contact athletes. ConclusionThe recurrence rate of Bankart repair in the contact athletes was 2 times higher in the open group and 3 times higher in the arthroscopic group than in the non-contact athletes. Clinical outcome of arthroscopic Bankart repair was similar to that of open procedure. Level of evidenceLevel IV, retrospective study.

Arthroscopic Stabilization for Recurrent Shoulder Instability With Moderate Glenoid Bone Defect in Patients With Moderate to Low Functional Demand

The purpose of this study was to investigate the functional outcomes of arthroscopic Bankart repair for recurrent shoulder instability in the setting of moderate glenoid bone defect ranging from 20% to 30% in patients with moderate to low functional demand. This study included 36 patients with unilateral recurrent instability and glenoid bone defects of 20% to 30% treated with arthroscopic stabilization. Glenoid bone loss was estimated on the en-face view of preoperative 3-dimensional computed tomography. Joint laxity was assessed clinically by use of the Beighton and Horan criteria, and patients were divided into 2 groups based on the presence of excessive joint laxity, group L (n=13), or absence of excessive joint laxity, group N (n= 23). Functional assessments were performed with the patient-reported activity level; subjective shoulder value; Rowe score; and University of California, Los Angeles shoulder score. The mean glenoid defect size was 25.1% (range, 20% to 29%), and the overall functional outcomes improved significantly after surgery. A return to greater than 90% of the premorbid activity level was reported by 72% of patients (26 of 36 patients), and patient satisfaction was 83% (30 of 36 patients). There was no significant difference in functional outcomes between groups L and N (subjective shoulder value, 85.0% for group L v 88.9% for group N, P= .397; Rowe score, 83.5 for group L v 92.8 for group N, P= .537; and University of California, Los Angeles shoulder score, 32.2 for group L v 31.9 for group N, P= .697). Recurrent instability occurred in 4 patients (11%), 3 patients in group L (3 of 13, 23%) and 1 patient in group N (1 of 23, 4%), but this difference was not statistically significant (P= .125). Arthroscopic stabilization for recurrent shoulder instability in patients with moderate to low functional demand produced satisfactory outcomes despite the presence of moderate glenoid bone defects of 20% to 30%. For patients with excessive joint laxity, however, arthroscopic stabilization may not be reliable, with a recurrence rate of 23%. Level IV, therapeutic case series.
