Arthroscopic Bankart Repair With Remplissage as an Alternative to Latarjet for Anterior Glenohumeral Instability With More Than 15% Glenoid Bone Loss.

Surgical management of anterior shoulder instability continues to evolve. The clinical effectiveness of arthroscopic Bankart repair with remplissage (REMP) in patients with increasing glenoid bone loss (GBL) has not been thoroughly compared with Latarjet. The purpose of this study was to compare 2-year outcomes of REMP versus open Latarjet in patients with >15% GBL. We hypothesized that there would be no difference. Cohort study; Level of evidence, 3. A multicenter, retrospective study was performed on a consecutive series of patients who underwent primary REMP or Latarjet by 4 shoulder specialists between August 2013 and December 2019 for >15% GBL. Procedure performance was based on shared decision making between the surgeon and patient. Baseline and 2-year postoperative range of motion (ROM) and the following patient-reported outcomes (PROs) were collected: Western Ontario Shoulder Instability Index, Single Assessment Numeric Evaluation, and visual analog scale for pain. Return to sport, satisfaction, complications, recurrence, and revisions were reviewed. A total of 47 patients were available for study, including 22 who underwent REMP and 25 who underwent Latarjet. Baseline demographic characteristics, ROM, and PROs were similar between the groups. Mean preoperative GBL (REMP 25.8% ± 7.8% vs Latarjet 25.1% ± 9.0%; P = .800) and off-track lesions (REMP 59.1% vs Latarjet 44.0%; P = .302) were similar. Postoperative change in external rotation favored Latarjet (10° ± 22° vs -4° ± 13°; P = .017). Postoperative PROs, return to the sports (86.4% vs 87.5%; P = .99), and satisfaction (95.5% vs 95.8%; P = .99) were similar between groups. There were no recurrent dislocations in either group. One infected hematoma was encountered in the Latarjet cohort. At short-term follow-up, the hypothesis was upheld. REMP and Latarjet provided similar outcomes for patients with >15% GBL, although REMP patients experienced slightly decreased external rotation. Although larger series and longer-term follow-ups are required, remplissage may be considered in patients with >15% glenoid bone loss.

The Short, 5-Item Shoulder Instability–Return to Sport After Injury Score Performs as Well as the Longer Version in Predicting Psychological Readiness to Return to Sport

To reduce the length of the Shoulder Instability-Return to Sport After Injury (SIRSI) scale and determine the predictive validity of the short version compared with the original form. This study included patients who underwent an arthroscopic Bankart repair or open Latarjet procedure between 2017 and 2019. One group was used for the SIRSI scale-reduction process, and a second group was used to test the predictive validity of the proposed short SIRSI scale. The Cronbach α value was used to evaluate internal consistency. Validity was determined by calculating the Pearson correlation coefficient with the Western Ontario Shoulder Instability Index scale. Predictive validity was assessed using receiver operating characteristic (ROC) curve statistics. A total of 158 patients participated in the scale-reduction process, and 137 patients participated in the predictive-validation process. The SIRSI scale was successfully reduced to a 5-item scale constructed by 1 underlying factor accounting for 60% of the variance. The short version showed good internal consistency (Cronbach α= 0.82) and was highly correlated with the Western Ontario Shoulder Instability Index scale and the long version. The short SIRSI scores were significantly different between patients who returned to sports and those who did not. The SIRSI scale had excellent predictive ability for return-to-sport outcomes (area under ROC curve of 0.84 for short version [95% confidence interval, 0.7-0.9] and 0.83 for long version [95% confidence interval, 0.7-0.9]). A valid 5-item, short version of the SIRSI scale was successfully developed in our patient population. Theshort version was found to be as robust as the long scale for discriminating and predicting return-to-sport outcomes. Level II, prospective cohort study.

Reliability, Validity and Responsiveness of the Polish Version of the Western Ontario Shoulder Instability Index (WOSI-PL) in Patients after Arthroscopic Repair for Shoulder Instability.

Apart from imaging and physical examination for shoulder instability (SI), medical history with patient feedback should be considered to assess the patient's condition and recovery. The aim of this study was to evaluate psychometric properties of the Polish version of Western Ontario Shoulder Instability Index (WOSI)-one of the most frequently used patient-reported outcome measures for SI. During examination 1, 74 patients after arthroscopic repair for SI (age x¯ = 30.01 ± 8.98) were tested. Examinations 2 and 3 involved 71 and 51 patients, respectively. They completed the Polish version of the WOSI, the shortened version of the Disabilities of Arm, Shoulder and Hand Questionnaire (QuickDASH), the Short Form-36 version 2.0 (SF-36 v. 2.0) and 7-point Global Rating Change scale (GRC). The WOSI-PL demonstrated high internal consistency (Cronbach's alpha for total = 0.94), and test-retest reliability (Total ICC2,1 = 0.99). High construct validity was found (89%) as the a priori hypotheses were confirmed. All domains and total scores of WOSI-PL showed a moderate to strong degree of responsiveness (ES = 0.37-0.44; SMR = 0.87-1.26). Minimal clinically important difference (MCID) for the Total WOSI-PL was 126.43 points/6% (95%CI 67.83-185.03) by the anchor-based method and 174.05 points/8% (95%CI 138.61-233.98) by the distribution-based method. The Polish version of the WOSI can be considered a reliable, valid and responsive PROM. It is recommended for assessing the quality of life in patients after arthroscopic repair for SI and can be applied in research and in the clinical setting for monitoring treatment and facilitating patient-centred therapeutic decisions.

Cross-Cultural Adaption and Validation of the Dutch Version of the Kerlan-Jobe Orthopaedic Clinic Questionnaire in Juvenile Baseball Pitchers.

Monitoring the performance and functional status of baseball pitchers' upper extremity is important in maintaining the athlete's health and performance. This study validated a Dutch translation of the original English Kerlan-Jobe Orthopaedic Clinic (KJOC) against the previously validated Disabilities of the Arm, Shoulder and Hand (DASH) and Western Ontario Shoulder Instability Index (WOSI) questionnaires in a group of talented juvenile Dutch baseball pitchers. Three times, from 2014-2016, 107 pitchers completed the Dutch KJOC, DASH and WOSI questionnaires. Participants' questionnaire scores were analysed for the whole group and the symptomatic player subgroup separately. Internal consistency, construct validity and ceiling and floor effects were examined. Cronbach's alpha was consistently above 0.8 for the three time periods for the whole group, and ranged between 0.62 and 0.86 for the symptomatic subgroup. Spearman's rank correlation coefficients ranged from 0.47 to 0.67 for the whole group and 0.32 to 0.99 for the symptomatic subgroup. No floor effects were observed in the scores of the KJOC and only a ceiling effect for the whole group (15.2%) at one time period. The Dutch version of the KJOC has shown acceptable internal consistency and construct validity and can be used to assess overhead athletes' shoulder and elbow functionality.

A novel arthroscopic transosseous suture-button fixation technique for anterior glenoid fractures

Abstract Background This study evaluated the clinical and radiological results of a new transosseous suture-button fixation technique for anterior glenoid fractures. Methods From March 2017 to May 2021, 23 patients with anterior glenoid fractures were treated with the new technique. Demographic data, active shoulder function, and several shoulder scores were evaluated after a minimum of 6 months. Fracture reduction and button placement were assessed via computed tomography, while fracture healing and onset or progression of glenohumeral osteoarthritis were evaluated with X‑rays. Results Overall, 57% of the patients had relevant concomitant intra-articular injury. Clinical follow-up was performed for 22 patients (19 male, 3 female) at 15 months (6.0–34.5) after surgery. The average Constant Score was 83.2 ± 16.7 points (93.4% ± 18.8% vs. the contralateral side), the Rowe Score, 90.7 ± 10.4 points, the Melbourne Instability Shoulder Score (/100), 88.3 ± 14.5 points, the Western Ontario Shoulder Instability Index (%), 82.9 ± 16.7, and the Subjective Shoulder Value (%), 86.9 ± 16.1. Average range of motion was 171.4 ° ± 22.7 ° of flexion (contralateral side, 180 ° ± 0 °; p = 0.11) and 170.5 ° ± 23.6 ° of abduction (contralateral side, 179.6 ± 2.1; p = 0.07). No complications occurred and no revision surgery was required. The postoperative step-off of the glenoid averaged 1.55 ± 1.05 mm (0–4 mm). Radiological follow-up of 19 patients showed fracture consolidation in all cases, without secondary dislocation of the fracture or of heterotopic ossification. There was no sign hardware impingement or dislocation. There was new-onset osteoarthritis in 3 cases (15.8%). We found no correlation between the step-off and radiological signs of osteoarthritis. Conclusion Anterior glenoid fractures were treated safely and reproducibly with the novel arthroscopic double-button-suture technique, but long-term results are still needed.

Glenohumeral Arthropathy After Arthroscopic Surgery for Shoulder Instability: Outcomes at 16-Year Follow-up

Glenohumeral arthropathy after surgery for traumatic shoulder instability is a condition whose etiology and long-term course are still unknown. To evaluate the risk factors for the onset of arthropathy and to assess the relationship between the degree of arthropathy and final outcomes. Case series; Level of evidence, 4. We included patients who underwent surgery for a shoulder instability at a single institution between 2000 and 2004. The following variables were studied for relationship with functional outcomes: sex, age, body mass index, smoking at the time of surgery, number of episodes of shoulder dislocation, and time from first dislocation to surgery. The number of anchors used and their position were also evaluated. Functional outcomes were assessed using the Constant-Murley, Western Ontario Shoulder Instability Index, and Rowe scores, and results were compared with the onset of arthropathy according to Buscayret classification. Spearman and Pearson correlations were performed for the association between glenohumeral arthritis (Buscayret grade) and the study variables, the Mann-Whitney U test and Student t test were used to compare outcome scores with the study variables, and the Kruskal-Wallis test was used to compare Buscayret grade and outcome scores. A total of 26 shoulders in 25 patients were analyzed, finding a high rate (54%) of arthropathy at a minimum follow-up of 16 years. Patients with Buscayret grade 4 had the worst functional results (P = .007). However, 80% of patients with Buscayret grade ≤3 had excellent Constant-Murley scores. A significant relationship was found between degree of arthropathy and patients who were smokers before surgery (P < .01). No relationship was found between the onset of arthropathy and the other variables analyzed. Postinstability glenohumeral arthropathy was not correlated with functional outcomes except in those patients with advanced arthroplasty (Buscayret grade 4). A direct relationship was found between smoking before surgery and the onset of glenohumeral arthropathy.

Arthroscopic Posterior Articular Coverage and Shift (PACS) Procedure for Treatment of Preosteoarthritic Constitutional Static Posterior Shoulder Instability (Type C1)

Background: Different joint-preserving techniques for treatment of preosteoarthritic, constitutional static (type C1) posterior shoulder instability (PSI) have been proposed, including posterior glenoid open wedge osteotomy and bone graft augmentation. However, the techniques are demanding, the reported complication and reoperation rates are high, and posterior decentering cannot reliably be reversed. Purpose: To assess the clinical and radiological longitudinal outcomes of patients with type C1 PSI after arthroscopic posterior articular coverage and shift (PACS) surgery. Study Design: Case series; Level of evidence, 4. Methods: We performed a retrospective analysis of a prospective database with longitudinal follow-up including 14 shoulders in 13 patients who underwent an arthroscopic PACS procedure for symptomatic preosteoarthritic constitutional static posterior instability (type C1) with previous failed nonoperative treatment. Patients were clinically evaluated before surgery and at 3, 6, 12, and 24 months postoperatively in terms of satisfaction and pain levels as well as standardized physical examination, Subjective Shoulder Value (SSV), Western Ontario Shoulder Instability Index (WOSI) score, Constant score, and Rowe score. Preoperative, postoperative, and follow-up magnetic resonance imaging scans were obtained in all patients. A paired 2-sample t test was used to compare changes in continuous variable parameters over time. Correlation analyses were performed using the Pearson correlation coefficient. Results: All outcome scores and the pain level improved significantly from preoperatively to postoperatively, and the improvement was sustained over the follow-up period of 2 years (pain level, 6.4 preoperatively vs 3.3 at 2 years, P < .001; SSV, 40 vs 70, P = .001; WOSI, 33 vs 56, P = .001; Constant, 70 vs 79, P = .049; Rowe, 52 vs 76, P < .001). The mean glenohumeral and scapulohumeral subluxation indices were significantly lower in the early postoperative period compared with preoperative measurements (glenohumeral, 52% ± 6% vs 58% ± 10%, P = .02; scapulohumeral, 70% ± 8%; vs 77% ± 9%, P = .002, respectively); however, they returned to baseline values at follow-up (57% ± 7% vs 58% ± 10%, P = .7; 75% ± 6% vs 77% ± 9%, P = .4, respectively). A high scapulohumeral subluxation index, excessive glenoid retroversion, and increased posterior positioning of the humeral head in relation to scapular blade axis and older age were correlated with worse clinical outcomes. Conclusion: Over the follow-up period of 2 years, the PACS procedure significantly improved outcome scores in patients who had preosteoarthritic constitutional static posterior shoulder instability, especially in younger patients with less severe glenoid retroversion and posterior decentering of the humeral head. However, similar to other techniques, the PACS procedure needs to be considered a symptomatic therapy that does not reverse the underlying cause or stop the progressive pathology.

Suspension fixation of iliac bone grafts under arthroscopy is an effective method for the treatment of unstable bony Bankart disease of the shoulder joint in patients with joint relaxation

PurposeTo evaluate the results of arthroscopic autologous iliac bone graft suspension fixation combined with the Remplissage procedure in the treatment of recurrent shoulder dislocation with bony Bankart lesions and joint hyperlaxity.MethodsFrom 2018 to 2020, 22 patients with joint laxity underwent arthroscopic autologous iliac bone graft suspension fixation and Bankart repair combined with the Remplissage procedure due to recurrent shoulder dislocation. Clinical assessment included range of motion (forward flexion, abduction, 90° external rotation, conventional external rotation, adduction, and internal rotation), visual analog scale (VAS) score, Rowe score, University of California Los Angeles (UCLA) score, and Western Ontario Shoulder Instability Index (WOSI) score. Post-operatively, the healing of the bone graft was evaluated with computed tomography (CT) scanning.ResultsAll 22 patients were followed up for a mean of 19.3 ± 4.1 months. CT imaging showed that the healing time of the bone graft was 6–8 weeks. The patient satisfaction rate was 100%, there were no cases of redislocation, all patients returned to their preinjury training state, and the fear test was negative. At the final follow-up, the UCLA, VAS, Rowe, and WOSI scores were 29.8 ± 2.1, 2.2 ± 0.8, 89.4 ± 4.2, and 482.3 ± 46.2, respectively (p < 0.001).ConclusionArthroscopic autologous iliac bone graft suspension fixation and Bankart repair combined with the Remplissage procedure are effective in preventing recurrent instability with joint hyperlaxity. Furthermore, no patient had redislocation.Level of evidenceIV.

Relationship of the SIRSI Score to Return to Sports After Surgical Stabilization of Glenohumeral Instability

Background: Literature is scarce regarding the influence of psychological readiness on return to sports after shoulder instability surgery. Purpose: To evaluate the predictive ability of the Shoulder Instability–Return to Sport after Injury (SIRSI) score in measuring the effect of psychological readiness on return to sports and to compare it between athletes who returned to sports and athletes who did not return to sports. Study Design: Cohort study; Level of evidence, 2. Methods: A prospective analysis was performed of patients who underwent an arthroscopic Bankart repair or a Latarjet procedure between January 2019 and September 2020. Psychological readiness to return to play was evaluated using the SIRSI instrument. Preoperative and postoperative functional outcomes were measured by the Rowe, Athletic Shoulder Outcome Scoring System, and Western Ontario Shoulder Instability Index scores. The predictive validity of the SIRSI was assessed by the use of receiver operating characteristic (ROC) curve statistics. The Youden index was calculated and used to determine a SIRSI score cutoff point that best discriminated psychological readiness to return to sports. A logistic regression analysis was performed to evaluate the effect of psychological readiness on return to sports and return to preinjury sports level. Results: A total of 104 patients were included in this study. Overall, 79% returned to sports. The SIRSI had excellent predictive ability for return-to-sport outcomes (return to sports: area under ROC curve, 0.87 [95% CI, 0.80-0.93]; return to preinjury sports level: area under ROC curve, 0.96; [95% CI, 0.8-0.9]). A cutoff level of ≥55 was used to determine whether an athlete was psychologically ready to return to sports and to return to preinjury sports level (Youden index, 0.7 and 0.9, respectively). Of those who returned to sports, 76.8% were psychologically ready to return to play, with a median SIRSI score of 65 (interquartile range, 57-80). In comparison, in the group that did not return to sports, only 4.5% achieved psychological readiness with a median SIRSI score of 38.5 (interquartile range, 35-41) (P < .001). Regression analysis for the effect of SIRSI score on return to sports was performed. For every 10-point increase in the SIRSI score, the odds of returning to sports increased by 2.9 times. Moreover, those who did not achieve their preinjury sports level showed poorer psychological readiness to return to play and SIRSI score results. Conclusion: The SIRSI was a useful tool for predicting whether patients were psychologically ready to return to sports after glenohumeral stabilization surgery. Patients who returned to sports and those who returned to their preinjury sports level were significantly more psychologically ready than those who did not return. Therefore, we believe that the SIRSI score should be considered along with other criteria that are used to decide whether the patient is ready to return to sports.

Translation, cross-cultural adaptation, and validation of the Turkish version of the shoulder instability-return to sport (SI-RSI) after injury scale

ABSTRACT To translate and culturally adapt the shoulder instability-return to sport after injury (SI-RSI) scale into Turkish (SI-RSI-Tr) and examine the psychometric properties of the Turkish version of athletes following a traumatic shoulder instability. The SI-RSI was translated into Turkish using Beaton guidelines. Sixty-nine patients with shoulder instability completed the translated SI-RSI, Western Ontario Shoulder Instability Index (WOSI), the Tampa Scale of Kinesiophobia (TSK), and the Walch-Duplay Scores. We analysed the internal consistency, agreement, reliability, and validity of the SI-RSI-Tr. The SI-RSI-Tr demonstrated excellent internal consistency (Cronbach’s alpha = 0.92), test–retest reliability (ICC = 0.95), and feasibility with no ceiling or floor effect. SI-RSI-Tr correlated with WOSI total score (r = −0.824, p < 0.001), its subscales: WOSI-physical (r = −0.683, p < 0.001), WOSI-sports (r = −0.832, p < 0.001), WOSI-lifestyle (r = −0.739, p < 0.001), and WOSI-emotions (r = −0.734, p < 0.001) respectively), Walch-Duplay (r = 0.840, p < 0.001) and TSK (r = −0.828, p < 0.001) scores. The Turkish SI-RSI is a reliable, internally consistent, and valid tool for athletes with shoulder instability. Researchers and clinicians could safely use the SIRSI-Tr to evaluate the shoulder-specific psychological factors on return to sports following an episode of shoulder instability.

Phone Administration of the Western Ontario Shoulder Instability Index Is More Reliable Than Administration via Email.

The Western Ontario Shoulder Instability (WOSI) questionnaire is a 21-item questionnaire to evaluate quality of life in patients with shoulder instability. Completing the questionnaire is time-consuming because each item is evaluated on a visual analog scale. Telephone or email versions of the score are appealing alternatives to administering it during the standard in-person patient visit; however, their validity and reliability remain unknown. (1) Does the numerical scale (NS) version of the WOSI correlate with the original WOSI and Quick-DASH? (2) Do telephone and email administration of the NS-WOSI have good reliability and consistency? (3) Compared with the original WOSI form, does the NS form lead to faster completion for patients and quicker data extraction for researchers? Between 2014 and 2019, 50 patients with a documented history of shoulder dislocation with persistent symptomatic shoulder instability, whether anterior, posterior, or multidirectional; patients scheduled for surgery; and patients with traumatic or nontraumatic injuries were prospectively recruited from the outpatient clinic of two university hospitals acting as Level 1 trauma centers and sports traumatology tertiary referral centers. The median (IQR) age was 28 years (24 to 36), and 80% (40 of 50) were men. Most (52% [26 of 50]) patients had two to five lifetime shoulder dislocations. Validity of the NS-WOSI was assessed using the Pearson correlation coefficient during an in-person visit; the original WOSI questionnaire (or its previously validated French-language version), NS-WOSI, and Quick-DASH questionnaires were administered in a random order. After a minimum 7-day interval, 78% (39 of 50) of patients completed the phone interview, and 74% (37 of 50) of patients completed the email version of the NS-WOSI score to evaluate NS-WOSI's reliability using the intraclass correlation coefficient (ICC), which was interpreted as poor (< 0.5), moderate (0.50-0.75), strong (0.75-0.90), and very strong (> 0.90). The standard error of measurement (SEM) was used to evaluate variability around the true score, with a low value indicating a high reliability. The 95% minimal detectable change (MDC 95% ) was calculated to evaluate the minimal change in score that was not related to measurement errors. Lastly, the Cronbach alpha was used to assess internal consistency (intercorrelation strength), where a value > 0.70 was considered good. The time needed for the patient to complete the various versions and for researchers to extract data was recorded. The NS-WOSI score was very strongly correlated with the original WOSI score (r = 0.96 [95% confidence interval (CI) 0.93 to 0.98]; p < 0.001). Although telephone-acquired and email-acquired data for the NS-WOSI questionnaires were correlated with the NS-WOSI (telephone r = 0.91 [95% CI 0.83 to 0.95]; p < 0.001; email r = 0.84 [95% CI 0.71 to 0.91]; p < 0.001), the ICC was higher for telephone interviews (0.92 [95% CI 0.86 to 0.96] versus email 0.80 [95% CI 0.64 to 0.89]), indicating that although both had good reliability, the phone interview was more suitable. The phone interview was also preferable to email regarding SEM (3% [52 of 2100 points] versus 6% [132 of 2100 points]) and the MDC 95% (7% [144 of 2100 points] versus 17% [366 of 2100 points]). The 95% CI of the MDC acquired by email was superior to the reported minimum clinically important difference for the original WOSI (7% [152 of 2100 points]), meaning that an error of measurement could wrongly be interpreted as a clinically significant change in score. Internal consistency was deemed good, with a Cronbach alpha of 0.96 (95% CI 0.92 to 98) and 0.89 (95% CI 0.79 to 0.94) for NS-WOSI telephone and email, respectively. The time to complete the NS-WOSI was reduced compared with the original WOSI (221 ± 153 seconds versus 266 ± 146 seconds, mean difference -45 seconds [95% CI -72 to -12]; p = 0.009). Lastly, data extraction was faster (62 ± 15 seconds versus 209 ± 52 seconds, mean difference -147 seconds [95% CI -164 to -130]; p < 0.001) with the NS-WOSI than with the original WOSI. The NS-WOSI in person, by telephone, or by email is a valid, reliable, and timesaving alternative to the original WOSI questionnaire. However, the reliability of data acquisition by telephone interviews was superior to that of email. Given that there were no important differences in performance for the NS-WOSI, regardless of whether it was administered in person or by phone, we suggest that physicians use both interchangeably based on patient convenience. However, we do not recommend using the email version, especially for research purposes, since it was not as reliable when compared with in-person administration. The responsiveness of the modified NS-WOSI, as well as factors influencing response rates to phone interview, are questions that remain to be explored.

Short- and long-term outcomes in Bankart repair vs. conservative treatment for first-time anterior shoulder dislocation: a systematic review and meta-analysis of randomized controlled trials.

First-time anterior shoulder dislocations are associated with a high rate of residual instability. Therefore, many surgeons support initial Bankart repair surgery over conservative management to address this issue. However, the optimal treatment remains controversial because of uncertainty regarding long-term surgical outcomes. The primary objective of this systematic review and meta-analysis was to compare the short- and long-term rates of residual instability following Bankart repair or conservative management after a first-time anterior shoulder dislocation. PubMed/MEDLINE, Embase, The Cochrane Library, Web of Science, CINAHL, and ScienceDirect databases were accessed for randomized controlled trials (RCTs) comparing Bankart repair to conservative management. RoB (Risk of Bias) 2 was used to check study quality. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines were followed in assessing primary outcomes. The inverse-variance method for continuous variables and the Mantel-Haenszel method for dichotomous variables was used. A total of 348 patients from 6 RCTs published across 8 articles, with a mean age of 23.7 years, were included. Bias was graded low in 3 studies, some concerns in 3 studies, and high in 2 studies. In the short term (2-3 years), surgery lowered recurrent instability (risk ratio [RR] 0.15, 95% confidence interval [CI] 0.08, 0.27; I2=0%; P<.0001). Similar findings were seen in the long term (5-12 years) (RR 0.23, 95% CI 0.14, 0.39; I2=0%; P<.0001). No difference was observed in return to sport (RR 1.18, 95% CI 0.91, 1.52; I2=78%; P=.21). Initial surgery lowered subsequent stabilization surgery in the short (RR 0.19, 95% CI 0.09, 0.43; I2=0%; P<.0001) and long term (RR 0.17, 95% CI 0.07, 0.39; I2=25%; P<.0001). Western Ontario Shoulder Instability Index (WOSI) scores did not differ in the short term (MD, 2.54, 95% CI -0.51, 5.59; I2=48%; P=.1) but were higher in the surgical group at long-term follow-up. Patient satisfaction was also higher with surgery (RR 1.75, 95% CI 1.4, 2.2; I2=88%; P<.0001). Certainty of evidence was low for only 1 long-term outcome measure. Bankart repair surgery for first-time anterior shoulder dislocation results in a large reduction in the risk of recurrent shoulder instability and subsequent stabilization surgery in both short- (2-3 years) and long-term (5-12 years) follow-up intervals. Additionally, slight improvements in overall patient satisfaction and WOSI score can be seen at long-term follow-up. However, surgical intervention failed to significantly improve the rate of return to sport when compared with conservative management.

The association between number of shoulder diagnoses and positive clinical tests with self-reported function and pain: A cross-sectional study of patients with hypermobile joints and shoulder complaints

BackgroundPatients with hypermobility spectrum disorder (HSD) and shoulder complaints may suffer from symptoms related to shoulder instability, laxity, and hypermobility. It is currently unknown whether having a more complex clinical status with several diagnoses (i.e., anterior instability (AI), multidirectional instability (MDI), and/or symptomatic localised shoulder hypermobility (LSH), relates to higher functional impairments and pain. ObjectivesTo investigate the associations between either ≤1, 2, or 3 clinical shoulder diagnoses (AI, MDI, and LSH) or the number (0–10) of positive clinical shoulder tests with shoulder function using the western Ontario shoulder instability index (WOSI, 0–2100, 0 = best) and pain intensity using numerical pain rating scale (NPRS, 0–10, 10 = worse). DesignExploratory cross-sectional study. MethodFrom a randomised controlled trial, baseline data from 100 participants with HSD and shoulder complaints for at least three months were included. Associations were investigated using linear regression models, adjusted for age, sex, body mass index, and hand dominance. ResultsCompared with having ≤1 diagnosis, neither participants with two (WOSI 76.9, 95% CI -136.3, 290.0; NPRS 0.3, 95% CI -0.9, 1.5) nor three (WOSI 35.5, 95% CI -178.5, 249.6; NPRS 0.1, 95% CI -1.1, 1.3) clinical shoulder diagnoses had significantly worse shoulder function or pain. Likewise, the number of positive clinical shoulder tests was not associated with function (WOSI -20.8 95%CI (−55.3, 13.7)) or pain (NPRS -0.1 95%CI (−0.2, 0.1)). ConclusionsIn participants with HSD and shoulder complaints, having more additional shoulder diagnoses or increased number of positive shoulder tests were not related to functional impairments or pain intensities.

Defining Minimal Clinically Important Difference and Patient Acceptable Symptom State After the Latarjet Procedure

Background: The Latarjet procedure is one of the most well-established treatment options for anterior shoulder instability. However, meaningful clinical outcomes after this surgery have not been defined. Purpose: This study aimed to establish the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) for commonly used outcome measures in patients undergoing the Latarjet procedure and determine correlations between preoperative patient characteristics and achievement of MCID or PASS. Study Design: Case series; Level of evidence, 4. Methods: A multicenter retrospective review at 4 institutions was performed to identify patients undergoing primary open Latarjet procedure with minimum 2-year follow-up. Data collected included patient characteristics (age, sex, sports participation), radiological parameters (glenoid bone loss, off-track Hill-Sachs lesion), and 4 patient-reported outcome measures (collected preoperatively and 2 years postoperatively): the American Shoulder and Elbow Surgeons (ASES) score, the Single Assessment Numeric Evaluation (SANE), the visual analog scale (VAS) for pain, and the Western Ontario Shoulder Instability Index (WOSI). The MCID and PASS for each outcome measure were calculated, and Pearson and Spearman coefficient analyses were used to identify correlations between MCID or PASS and preoperative variables (age, sex, sports participation, glenoid bone loss, off-track Hill-Sachs lesion). Results: A total of 156 patients were included in the study. The MCID values for ASES, SANE, VAS pain, and WOSI were calculated to be 9.6, 12.4, 1.7, and 254.9, respectively. The PASS values for ASES, SANE, VAS pain, and WOSI were 86.0, 82.5, 2.5, and 571.0, respectively. The rates of patients achieving MCID were 61.1% for VAS pain, 71.6% for ASES, 74.1% for SANE, and 84.2% for WOSI. The rates of achieving PASS ranged from 78.4% for WOSI to 84.0% for VAS pain. There was no correlation between any of the studied preoperative variables and the likelihood of achieving MCID or PASS. Conclusion: This study defined MCID and PASS values for 4 commonly used outcome measures in patients undergoing the Latarjet procedure. These findings are essential for incorporating patient perspectives into the clinical effectiveness of the Latarjet procedure and provide valuable parameters for the design and interpretation of future clinical trials.

Cross-cultural Adaptation and Validation of the European Portuguese Version of the Western Ontario Shoulder Instability Index (WOSI).

The Western Ontario Shoulder Instability Index (WOSI) is a self-administered questionnaire specifically used to determine the impact of shoulder instability on quality of life. The aim of this study was to translate the WOSI into European Portuguese and analyze its validity and reliability in a population with shoulder instability. The WOSI was translated and culturally adapted from its original version into European Portuguese (WOSIPT). Internal consistency and test-retest analyses were conducted to determine the level of reliability of the scale. WOSI-PT, Quick-DASH, and SF-12 questionnaires were applied to 81 patients with symptomatic shoulder instability to assess validity, and reliability was tested by randomly selecting 50 patients within 72 hours using a test-retest design. The reliability of the WOSI-PT was very high, with Cronbach´s alpha equal to 0.97 and an intraclass correlation coefficient of 0.98. Regarding the construct validity, the correlation between the WOSI-PT and QuickDASH was high and negative (-0.79). The correlations between WOSI-PT and SF-12 were positive, respectively, moderate with physical (0.66) and low with mental (0.34) health. WOSI-PT is a reliable and valid instrument for assessing the functional impact of shoulder joint instability on quality of life.

Clinical outcomes following open anterior shoulder stabilization for glenohumeral instability in the young collision athlete.

Anterior glenohumeral instability occurs most commonly in those aged 15-29, with 72% of individuals younger than 22 years suffering recurrent episodes; collision athletes are at particular risk. In the setting of subcritical glenoid bone loss, arthroscopic Bankart repair is widely used despite concerns of recurrent dislocations when compared with open techniques. Furthermore, indications for bone-block procedures are evolving with the Latarjet procedure being favored amongst recent authors as a primary stabilization method in elite and contact athletes. To determine the efficacy of open modified Bankart stabilization in treating anterior glenohumeral instability in young collision athletes. This was a retrospective review of outcomes of consecutive patients aged 15-20 years who underwent unilateral or bilateral open stabilization for recurrent anterior glenohumeral instability over a 7-year period (2007-2015). The cohort was selected as recent literature suggests that this is the group with the highest redislocation rate and poorest outcomes. Outcome assessments included redislocation rate, return to sport, pain score, patient-related satisfaction scores, and the Western Ontario Shoulder Instability Index. A total of 60 patients (55 male: 5 female) of mean age 18 years (range: 15-20 years) were available for follow-up at 7 years. All but 3 were competitive athletes with 18 competing regionally and 9 internationally; rugby union and rugby league represent the most common sports. Fifty-five of 60 (92%) have returned to their desired level of sport with 62% of athletes returning to their previous level of competition sport and 1 retuning at a higher level. The mean postoperative pain score was 2.5/10. The mean time to return to play was 14 months (range: 5-48 months). Eight of 60 shoulders reported redislocation (13%), 7 of these being traumatic dislocations after return to high-impact sporting activities. At 7 years of follow-up, 4 of 60 shoulders (7%) had undergone revision surgery. Young collision athletes represent a challenging cohort of instability patients. This study of open modified Bankart in young collision sport athletes revealed excellent outcomes with 92% return to sport and a low revision rate. The results from this cohort rival those of arthroscopic repair. The open procedure described here in this 7-year series represents a robust, reliable technique that could be considered as an alternative to arthroscopic Bankart due to concern for recurrence, while avoiding potential morbidity and complication of bone-block procedures. There is still a role for the open modified Bankart procedure in treating traumatic anterior instability.

Arthroscopic Treatment of Anterior Shoulder Instability Using Suture Anchors With Pre-Tied Knots in the Beach Chair Position

Background: Arthroscopic Bankart repair is routinely performed for treatment of anterior shoulder instability. Although an overall successful procedure, arthroscopic free-hand knot tying can be challenging and inconsistent, even for experienced surgeons. Knotless anchors, on the other hand, pose challenges in developing consistent good loop security prior to implantation, and, in the absence of a secure loop tissue tension on the glenoid face, might be inadequate. As an alternative, suture anchors with pre-tied knots offer the strength and security of knots without the need to perform complex and unreliable free-handed ties. Furthermore, loop security is consistent, reliable, and effective with each anchor. Indications: Patients with anterior labral tears and minimal bone loss are candidates for arthroscopic Bankart repair. The goal of surgery is to restore a robust tissue profile and statically keep the humeral head well-seated within the glenohumeral joint space. Technique Description: We demonstrate how to perform Bankart repair using suture anchors with pre-tied knots. The torn labrum is first mobilized and elevated, and suture anchors are placed along the glenoid rim from inferior to superior, treating the torn tissue as “rungs of a ladder.” The pre-tied sliding knot secures the restored labrum, along with glenohumeral ligaments and capsule, as necessary, using only a limited number of incrementally tensioned half hitch knots. Results: Of the 30 patients treated for anterior shoulder instability using this technique, the majority met the minimal clinically important improvement in the American Shoulder and Elbow Surgeons Shoulder Score, Western Ontario Shoulder Instability Index, and Marx activity scale by 2 years. Two patients reported experiencing subsequent minor subluxation events that improved following short courses of physical therapy, and no patients sustained subsequent frank dislocations. Discussion/Conclusion: Using suture anchors with pre-tied knots for arthroscopic Bankart repair allows for fast, easy, and consistently dependable reconstruction of the labrum and leads to reliable clinical outcomes.

Consideration May Be Given to Lowering the Threshold for the Addition of Remplissage in Patients With Subcritical Glenoid Bone Loss Undergoing Arthroscopic Bankart Repair

PurposeTreatment for patients with anterior glenohumeral instability with subcritical bone loss is evolving. The purpose of this study was to compare 2-year outcomes of arthroscopic Bankart repair with and without Hill–Sachs remplissage in patients with <15% glenoid bone loss.MethodsA multicenter retrospective study was performed on a consecutive series of patients who underwent primary isolated arthroscopic Bankart repair (IBR) or arthroscopic Bankart repair with remplissage (REMP) by 4 shoulder specialists between 2013 and 2019. Range of motion (ROM) and patient-reported outcomes (PROs) were collected at baseline and 2 years postoperative: Western Ontario Shoulder Instability Index, Single Assessment Numeric Evaluation, and visual analog scale for pain. Recurrence, return to sport, satisfaction, complications, and revisions also were reviewed.ResultsA total of 123 patients were available, including 75 IBR and 48 REMP. Baseline demographics, activity, ROM, and PROs were similar. Mean glenoid bone loss (2.5% vs 6.1%: P < .001) was greater in REMP, although the number of on-track lesions was similar (98.7% vs 93.8%: P = .298). WOSI scores were improved for REMP (196.5 vs 42.7: P = .004), but otherwise no difference in postoperative PROs or ROM. Differences between cohorts did not reach significance in return to sport (73% vs 83%: P = .203), recurrence (9.3% vs 2.1%: P = .148), or revisions (6.8% vs 2.1%: P = .403). For on-track lesions there were 6 recurrences in IBR (6 of 74; 8.1%) and 1 recurrence in REMP (1 of 45; 2.2%).ConclusionsDespite slightly worse pathology, patients with subcritical bone loss who undergo REMP experience similar short-term postoperative function to isolated IBR. Recurrence, revision, and return to sport favored REMP but this study was underpowered to show statistical significance. Recurrence was common following IBR, despite subcritical glenoid bone loss and primarily on-track lesions, suggesting that REMP can be considered in on-track lesions.Level of EvidenceIII, retrospective comparative study.
