J Shoulder Elbow Surg 2020; 29:S107-S114. [PMID: 32643605 DOI: 10.1016/j.jse.2020.04.035] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 04/27/2020] [Accepted: 04/28/2020] [Indexed: 02/01/2023]
Abstract
OBJECTIVES A good outcome after arthroscopic stabilization for recurrent shoulder instability is often characterized by a successful return to sport while minimizing complications. There is currently no consensus regarding timing or objective criteria for return to sport. The objective of this study is to evaluate the ability of postoperative patients to meet expected goals by using standardized objective evaluations of strength and physical function. METHODS Forty-three (10 females, 76.7% male) subjects (mean age, 18.1 ± 3.7 years) who underwent arthroscopic shoulder stabilization surgery (anterior or posterior) from 2016 until 2018 were referred during their postoperative rehabilitation for functional testing at 6 months postoperatively to evaluate their readiness for return to sport. The Closed Kinetic Chain Upper Extremity Stability test and Unilateral Seated Shot Put test were used to assess shoulder function. Posterior rotator cuff activation was evaluated using a repetition to failure technique with 5% body weight at 0° and 90° of abduction with the goal of 90% of nonoperative extremity. Isokinetic strength testing of external rotation (ER) and internal rotation (IR) was evaluated using a Biodex isokinetic dynamometer at angular velocities of 60° and 180° per second, and a passing score was considered achieving 90% of nonoperative shoulder strength at both 60° and 180° per second. RESULTS All subjects were competitive athletes (20 collegiate, 23 high school). The dominant extremity was the surgical extremity in 22 subjects. Only 5 subjects were able to successfully pass the battery of tests for strength and function. Strength testing revealed that 7 patients achieved 90% of the strength of the nonoperative extremity in both repetitions to failure (23 of 43) and comparative isokinetic testing (7 of 43). More subjects were able to meet IR strength (20 of 43) than ER strength (12 of 43) goals. Functional test goals were more frequently achieved, with 26 of 43 subjects meeting both functional test goals (33 Closed Kinetic Chain Upper Extremity Stability, 34 Unilateral Seated Shot Put). Only 2 subjects were able to achieve strength goals but did not pass functional tests, whereas 21 subjects passed functional tests without meeting strength goals. CONCLUSION A substantial number of athletes in our cohort do not meet the expected goals for their operative shoulder in achieving appropriate function and strength, compared with the contralateral shoulder. Functional goals were more often met than strength. IR strength goals were more frequently achieved than ER strength. Strength and functional testing could provide more reliable criteria than arbitrary passage of time for return to play after shoulder stabilization surgery.

J Shoulder Elbow Surg 2020; 29:1479-1483. [PMID: 32197807 DOI: 10.1016/j.jse.2019.12.007] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 12/05/2019] [Accepted: 12/10/2019] [Indexed: 02/01/2023]
Abstract
BACKGROUND This study presents a new technique for assembling an all-suture anchor from existing medical products. The biomechanical characteristics of this self-made anchor (SMA) are compared with those of an industrially manufactured all-suture anchor. METHODS The SMAs were made from established medical products (FiberWire #2 and 2-mm FiberTape; Arthrex, Naples, FL, USA). Pretesting was performed in biphasic polyurethane foam blocks. In the next step, 10 SMAs and 10 industrially made anchors (IMAs; 1.8-mm double-loaded Y-Knot Flex all-suture anchor; ConMed Linvatec, Largo, FL, USA) were applied with an insertion tool and tested in fresh porcine femora using a servohydraulic testing system, with a preload of 10 N and a displacement rate of 12.5 mm/s. Pullout strength and failure mode were recorded. RESULTS The mean load at failure in the foam blocks was 459 ± 124 N in the SMA group and 538 ± 83 N in the IMA group. In porcine bone, failure occurred at 461 ± 102 N in the SMA group and 431 ± 135 N in the IMA group. The differences in pullout strength between the 2 types of anchor were not statistically significant, either in the foam blocks (P = .17) or in porcine bone (P = .62). CONCLUSION A handmade all-suture anchor using 2 high-strength sutures woven into a 2-mm strip of high-strength tape did not show statistically different failure loads in polyurethane foam or in porcine metaphyseal bone in comparison with a commercially produced double-loaded all-suture anchor. The principal mode of failure in porcine bone in both groups was anchor pullout.

Anchor placement to glenoid rim during Bankart repair recreates contact area of anterior capsulolabral complex on glenoid better than onto articular surface. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2020; 30:1257-1262. [PMID: 32418057 DOI: 10.1007/s00590-020-02694-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Accepted: 05/06/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE This study aimed to compare the contact areas of Bankart repair with suture anchors placed on the articular surface of the glenoid versus at the rim of the glenoid because it is unclear which technique most effectively restores the footprint after Bankart repair. METHODS Ten fresh frozen cadaveric shoulders (mean age 70.7 years) were dissected. The attachment site of the capsulolabral complex from the 1 o' clock position to the 6 o'clock position was marked with ink, and the contact area of the anterior-inferior capsulolabral complex on the glenoid neck was measured using imageJ. Bankart lesions were created, and two types of Bankart repair were performed on each specimen. The suture anchors were inserted at the glenoid rim (Rim group) and onto the glenoid articular surface 2 mm from the rim (Surface group). Using pressure-sensitive films, we examined the interface contact area. RESULTS The Rim group recreated 64.9% of the native surface area, while the Surface group recreated 47.3% of the area. The Rim group recreated significantly greater contact area compared to the Surface group (P = 0.0008). CONCLUSION The anchor placement to the glenoid rim recreates the footprint of the capsulolabral complex on the anterior inferior glenoid better than the anchor placement onto the articular surface.

Abstract
BACKGROUND Shoulder instability in young athletes is a complex problem with higher recurrence, higher reoperation, and lower return to sport (RTS) rates after arthroscopic shoulder stabilization compared with adults. METHODS This is a prospective case series of young athletes with anterior shoulder instability after arthroscopic stabilization surgery. Primary outcomes were RTS and revision surgery, minimum follow-up was 24 months. Exclusion criteria were more than 3 preoperative episodes of instability, significant bone loss, or primary posterior instability. Demographic data, recurrent instability, revision surgery, sports pre- and postsurgery, patient satisfaction, level of RTS, time to RTS, and Single Assessment Numeric Evaluation (SANE) scores were analyzed. RESULTS Sixty-seven athletes met inclusion criteria, 19 females and 48 males, with a mean age of 17.5 years (range, 13-21 years). Fifty-nine (88%) athletes returned to sport at an average of 7.1 months (standard deviation, ±1.8); 50 (75%) returned to the same level or higher. Football and lacrosse were the most common sports. Four of 67 athletes (6%), all male, underwent revision stabilization at 11-36 months for recurrent instability. The overall mean SANE score was 88. CONCLUSION This study demonstrates that when the high-risk athlete, 21 years old or younger, is appropriately selected for arthroscopic shoulder stabilization by excluding those with 3 or more preoperative shoulder instability episodes and those with off-track and engaging instability patterns, excellent outcomes can be achieved with low revision surgery rates, high RTS rates, and high patient satisfaction.

Abstract
Background The arthroscopic method offers a less invasive technique of Bankart repair for traumatic anterior shoulder instability. The aim of the study is to determine the mid−/long-term functional outcome, failure rates and predictors of failure after primary arthroscopic Bankart repair for traumatic anterior shoulder instability. Methods A total of 100 patients were primarily operated using arthroscopic Bankart repair after traumatic anterior shoulder instability. Medical records were retrospectively reviewed, and patients were assessed using postal questionnaire after a mean follow-up of 8.3 years [3–14]. Clinical assessment was performed using Constant score, Rowe score, and American Shoulder and Elbow Surgeons score. Results The overall recurrence rate was 22%. The Kaplan-Meier failure-free survival estimates. were 80% at 5 years and 70% at 10 years. Nearly half (54.5%) of recurrences occurred at 2 years postoperative. Compared with normal shoulder, there were statistical differences in all 3 scores. Failure rate was significantly affected by age at the time of surgery with 86% of recurrence cases observed in patients aged 30 years or younger. Nevertheless, Younger age at the time of surgery (P = 0.007) as well age at the time of initial instability (P = 0.03) was found to correlate negatively with early recurrence within 2 years of surgery. Among those with recurrent instability, recurrence rate was found to be higher if there had been more than 5 instability episodes preoperatively (P = 0.01). Return to the preinjury sport and occupational level was possible in 41 and 78%, respectively. Conclusion Failure-free survival rates dropped dramatically over time. Alternative reconstruction techniques should be considered in those aged ≤30 years due to the high recurrence rate.

Abstract
Hypothesis The purpose was to investigate joint stability and range of motion after a Bankart repair without superior labral anterior-posterior (SLAP) repair (termed “Bankart repair”) and after combined Bankart and SLAP repairs (termed “combined repair”). Methods Eight fresh-frozen shoulders were used. Combined Bankart and SLAP lesions were created (10- to 6-o'clock positions). The labrum and capsule were repaired at the 2-o'clock, 3:30 clock-face, and 5-o'clock positions in the Bankart repair group and at the 11-o'clock, 1-o'clock, 2-o'clock, 3:30 clock-face, and 5-o'clock positions in the combined repair group. The internal- and external-rotation ranges of motion were determined with the arm positioned at 0° and 60° of glenohumeral abduction. The rotation angle was defined when a constant torque of 200 N-mm was applied. Joint stability was measured with a custom stability-testing device. The peak translational force in the anterior-posterior direction was measured with the arm at the end range of external rotation. Results External rotation angles were greater at 0° and 60° of abduction in the Bankart repair group than in the combined repair group (0° of abduction, P < .01; 60° of abduction, P < .05). The internal rotation angle was greater at 60° of abduction in the Bankart repair group than in the combined repair group (P < .01). The stability between the 2 groups was not significantly different (P = .60). Conclusion In patients with combined Bankart and SLAP lesions and the need for a wide range of motion, a Bankart repair alone may provide a greater range of motion without compromising the joint stability at the end range compared with a combined repair.

Abstract
BACKGROUND Literature on outcomes of arthroscopic Bankart repair at the intervening time intervals in traumatic recurrent dislocation of shoulder joint is limited. STUDY DESIGN Case series. SUBJECTS AND METHODS 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. RESULTS 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. CONCLUSION Arthroscopic Bankart repair is an effective and safe technique for treating anterior glenohumeral instability in patients with recurrent traumatic shoulder dislocation.

Abstract
BACKGROUND Patients who have undergone shoulder instability surgery are often allowed to return to sports, work, and high-level activity based largely on a time-based criterion of 6 months postoperatively. However, some believe that advancing activity after surgery should be dependent on the return of strength and range of motion (ROM). HYPOTHESIS There will be a significant loss of strength or ROM at 6 months after arthroscopic Bankart repair with remplissage compared with Bankart repair alone. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS A total of 38 patients in a prospective multicenter study underwent arthroscopic Bankart repair with remplissage (33 males, 5 females; mean age, 27.0 ± 10.2 years; 82% with ≥2 dislocation events in the past year). Strength and ROM were assessed preoperatively and at 6 months after surgery. Results were compared with 104 matched patients who had undergone Bankart repair without remplissage, although all had radiographic evidence of a Hill-Sachs defect. RESULTS At 6 months, there were no patients in the remplissage group with anterior apprehension on physical examination. However, 26% had a ≥20° external rotation (ER) deficit with the elbow at the side, 42% had a ≥20° ER deficit with the elbow at 90° of abduction, and 5% had persistent weakness. Compared with matched patients who underwent only arthroscopic Bankart repair, the remplissage group had greater humeral bone loss and had a greater likelihood of a ≥20° ER deficit with the elbow at 90° of abduction (P = .004). Risk factors for a ≥20° ER deficit with the elbow at 90° of abduction were preoperative stiffness in the same plane (P = .02), while risk factors for a ≥20° ER deficit with the elbow at the side were increased number of inferior quadrant glenoid anchors (P = .003), increased patient age (P = .02), and preoperative side-to-side deficits in ER (P = .04). The only risk factor for postoperative ER weakness was preoperative ER weakness (P = .04), with no association with remplissage (P = .26). CONCLUSION Arthroscopic Bankart repair with remplissage did not result in significant strength deficits but increased the risk of ER stiffness in abduction compared with Bankart repair without remplissage at short-term follow-up.

Abstract
BACKGROUND The accuracy of surgeons in utilizing the clock face method for anchor placement has never been investigated. Our hypothesis was that shoulder arthroscopy surgeons would be able to place suture anchors at predetermined positions with accuracy and reliability. METHODS Ten cadaveric shoulders were used. Five fellowship-trained shoulder arthroscopy surgeons were directed to place a suture anchor at 3:30, 4:30, and 5:30 clock in two shoulders each. The position of the anchors was determined with computed tomography. The accuracy of placement was calculated and data analyzed with one-way analysis of variance. The intraclass correlation coefficients were calculated. RESULTS The overall accuracy was 57%. The accuracy of anchor placement at the 3:30 position was 40% (average position 2:24 o'clock), it was 50% at the 4:30 position (average position 3:42 o'clock) and 80% at the 5:30 position (average position 5:03 o'clock). No statistical difference in accuracy between the placement of the superior, middle, and inferior anchors (p = 0.145) was seen. The intraclass correlation coefficient for inter-surgeon reliability was 0.4 (fair) while the intraclass correlation coefficient for intra-surgeon reliability was 0.6 (moderate). DISCUSSION The findings of this study suggest a moderate degree of accuracy and fair to moderate inter- and intra-surgeon reliability when using the clock face system to guide anchor placement.

Abstract
PURPOSE To evaluate the efficacy of the Instability Severity Index Score (ISIS) in predicting an increased recurrence risk after an arthroscopic Bankart repair. METHODS Retrospective review of a cohort of patients operated in three different centres. The inclusion criteria (recurrent anterior instability [dislocation or subluxation] with or without hyperlaxity, arthroscopic Bankart repair) and the exclusion criteria (concomitant rotator cuff lesion, acute first-time dislocation, surgery after a previous anterior stabilization, surgery for an unstable shoulder without true dislocation or subluxation; multidirectional instability) were those used in the study that defined the ISIS score. The medical records and a telephone interview were used to identify the six variables that define the ISIS and identify recurrences. RESULTS One hundred and sixty-three shoulders met the inclusion and exclusion criteria. Of these, 140 subjects (22 females/118 males; mean age 35.5 ± 7.9) with 142 (89.0%) shoulders were available for follow-up after 5.3 (1.1) (range 3.1-7.4) years. There were 20 recurrences (14.1%). The mean (SD) preoperative ISIS was 1.8 (1.6) in the patients without recurrence and 1.8 (1.9) in the patients with recurrence (n.s.). In the 117 subjects with ISIS between 0 and 3 the recurrence rate was 12.8%; in the 25 with ISIS 4 to 6 the rate was 20% (n.s.). CONCLUSION For subjects with anterior shoulder instability in which an arthroscopic Bankart repair is being considered, the use of the ISIS, when the values obtained are ≤ 6 was not useful to predict an increased recurrence risk in the midterm in this retrospectively evaluated case series. The efficacy of the ISIS score in defining a group of subjects with a preoperative increased risk of recurrence after an arthroscopic Bankart instability repair is limited in lower risk populations (with ISIS scores ≤ 6). LEVEL OF EVIDENCE Retrospective case series, Level IV.

Abstract
BACKGROUND It has been biomechanically demonstrated that 20% to 25% is a critical glenoid bone loss. Recently, there are several reports describing that a bone loss less than 20% to 25% needed to be treated because patients may have decreased quality of life without recurrent instability events. The purpose of this study was to clarify the presence of subcritical bone loss that would affect postoperative instability or quality of life. METHODS Subjects were 43 patients aged≤40years with less than 25% glenoid bone loss who had undergone arthroscopic Bankart repair. These patients were assessed at a mean follow-up of 32months. The Western Ontario Shoulder Instability (WOSI) and Rowe scores were used for the clinical evaluation. Patients were divided in 3 groups based on the percentage of bone loss: group 1: <8%; group 2: 8% to 17%; and group 3: >17%. RESULTS The recurrence rate was 7% (3/43 shoulders). A weak negative correlation was seen between bone loss and sports/recreation/work domain of the WOSI score (r=-0.304, p=0.0191). The WOSI for group 3 was significantly lower than that for group 1 and 2 (p=0.0009). The male WOSI scores were significantly lower than the female ones (p=0.0471). The WOSI scores of the contact athletes were significantly lower than those of non-contact athletes (p=0.0275). All the patients in Group 3 were males and participated in contact sports. CONCLUSION Glenoid bone loss between 17% and 25% is considered to be a "subcritical bone loss" in our series, especially in male patients who are involved in sports or high-level activities. LEVEL OF EVIDENCE III, retrospective study.

Abstract
Background We previously reported a hybrid suture technique, wherein mattress and simple suturing are used to create Mason-Allen configuration, with low recurrence rates. This comparative study looking at the two years’ clinical outcomes of arthroscopic anterior labral repair using the hybrid suture technique versus simple suture technique. Methods We identified 103 patients who underwent arthroscopic anterior labral repair from 2010 to 2015 with 2-year follow-up. The patients were categorized into two groups: hybrid suture technique (65 patients) and simple suture technique (38 patients). Clinical outcomes measures included UCLA shoulder score, Constant Shoulder Score, Numerical Pain Rating Scale, and Oxford Instability score. Results Mean age of the patients was 27.02 ± 9.76 years (17–63), with 91 males and 12 females. At 24 months, both groups showed significant improvement in post-operative clinical scores compared to pre-operation. The patients in hybrid sutures technique demonstrated significant improvement in Constant Shoulder Score, UCLA shoulder score and Oxford Instability score compared to simple suture group at 3 months follow up. (121.98 ± 21.05 vs 109.32 ± 21.15, p < 0.05; 65.5 ± 19 vs 57.4 ± 17.6, p < 0.05; 27.3 ± 5.7 vs 23.7 ± 5.0, p < 0.05; 29.3 ± 8.9 vs 33.4 ± 8.2, p < 0.05). The postoperative recurrence rate was comparable between both groups (hybrid suture group 7.81% vs simple suture group 7.84%). Conclusions Arthroscopic anterior labral repair with hybrid suture technique offers significant early improvements in clinical scores and low recurrence rate compared to simple suture technique at 2-year follow-up.

Abstract
Purpose Treatment options appear lacking for patients with epileptic seizure-induced shoulder dislocations who are not candidates for shoulder and focus resection surgeries. To reduce shoulder joint dislocations caused by epileptic seizures and simultaneously reduce the frequency and intensity of seizures, we performed corpus callosotomy for two patients with medically intractable epilepsy that induced repetitive shoulder joint dislocations. Materials and methods A 21-year-old man (Patient 1) with bilateral temporal lobe epilepsy [Focal onset impaired awareness seizure (FIAS), 1/month; focal to bilateral tonic-clonic seizure (BTCS), 1/2–3 months], autism and intellectual disorder and a 34-year-old man (Patient 2) with left multi-lobar epilepsy (BTCS, 3–4/month; status epilepticus, 1/2–3 months), autism and intellectual disorder had suffered from repetitive seizure-induced shoulder dislocations (1/2–3 months for Patient 1; 3–4/month for Patient 2). Due to frequent seizures and uncooperativeness, they were not candidates for shoulder joint dislocation surgery. They were also not candidates for focus resection surgery due to multiple foci and uncooperativeness for invasive monitoring. We performed corpus callosotomy for both patients. Results Postoperatively, frequencies of both shoulder dislocations (2 in 5 years of follow-up for Patient 1; 1 in 5 months of follow-up for Patient 2) and epileptic seizures were drastically reduced. Conclusions For patients who are not candidates for focus resection and shoulder joint surgeries but who suffer from frequent shoulder joint dislocations, corpus callosotomy could be a treatment of last resort.

Long-term clinical outcome of arthroscopic Bankart repair with suture anchors. J Shoulder Elbow Surg 2019; 28:e137-e143. [PMID: 30577997 DOI: 10.1016/j.jse.2018.09.027] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2018] [Revised: 09/17/2018] [Accepted: 09/22/2018] [Indexed: 02/01/2023]
Abstract
BACKGROUND 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. METHODS 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. RESULTS 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). CONCLUSION 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.

Abstract
Capsulolabral reconstruction (Bankart repair) is recommended as the first line treatment in young and functionally demanding active patients with anteroinferior shoulder instability, due to the high tendency to recurrent dislocation. This has become established both for arthroscopic and open primary shoulder stabilization with good clinical outcome; nevertheless, recurrence of dislocation is reported in up to 25% of patients. Risk factors for failed surgery are patient (e.g. young age, male gender and contact sports) and surgery (e.g. primarily underestimated glenoid bone loss, Hill-Sachs lesion, non-treatment of bipolar defects or malpositioned anchors) related. In the management of recurrent instability, it is necessary to carry out a thorough clinical investigation in addition to extended diagnostics with X‑ray and computed tomography. A second Bankart repair is only indicated in patients with low demands and without any glenoid bone loss. In the majority of patients, bony augmentation of the glenoid is necessary and realized by coracoid or iliac crest bone block transfer. The Latarjet procedure is biomechanically advantageous due to the additional sling effect of the conjoined tendons and both techniques show good clinical outcomes and a low recurrence rate. Furthermore, engaging Hill-Sachs lesions also require additional treatment. Remplissage of the infraspinatus muscle, iliac crest bone block transfer and partial joint replacement are viable options. A final consensus for treatment of Hill-Sachs lesions has yet to be defined. Dislocation arthropathy is an underestimated complication as a result of frequent recurrent dislocations. After development of dislocation arthropathy, patients reported a painful restriction of range of motion rather than instability. Arthroscopic arthrolysis and comprehensive arthroscopic management (CAM procedure) are possible joint-preserving treatment options.

Abstract
Background Biodegradable suture anchors are associated with higher redislocation rates. This study examined whether the biocompatibility and/or biomechanical properties of suture anchors contribute to the increase in complications. Methods Human glenohumeral capsule cells were cultured with 4 types of suture anchors, Opus LabraFix (titanium alloy; ArthroCare, Austin, TX, USA), PushLock (poly-ether-ether-ketone; Arthrex, Naples, FL, USA), BioKnotless (poly-l-lactic acid; DePuy Mitek, Warsaw, IN, USA), and Suretac II (polyglycolic acid; Smith & Nephew, London, UK), to measure cell viability and pH. Four groups of 6 ovine shoulders were used to repair the labrum, which was completely detached from the glenoid rim anteroinferiorly and reattached with 2 suture anchors and subject to failure load testing. Results In cell culture, BioKnotless at 48 and 72 hours (85.2% ± 2.1% and 84.5% ± 3.6%) and Suretac II groups (33.9% ± 3.1% and 42.8% ± 6.4%) had fewer viable cells compared with control (P = .048). The pH of Suretac II was lower than control (7.51 to 7.65) at 24 hours (7.31 ± 0.08, P = .049), 48 hours (7.25 ± 0.02, P = .046), and 72 hours (7.29 ± 0.04, P = .04). During mechanical testing, 83% of repairs failed by the capsule tearing. Among the anchors, the BioKnotless repair group had a significantly lower failure load (37 ± 5 N) compared with the PushLock (61 ± 7 N), Opus (60 ± 6 N), and Suretac II (57 ± 7 N) groups (P = .038). Conclusion BioKnotless and Suretac II anchors are cytotoxic. The BioKnotless biodegradable anchor has significantly lower failure load. Absorbable suture anchors may cause higher redislocation of arthroscopic Bankart repair.

Abstract
Facilitation of healing is important for the anteroinferior glenohumeral ligament-labrum complex (AIGHL-LC) after Bankart repair in shoulder dislocation. The purpose of this study was to investigate the effect of subscapularis muscle loading on contact area and contact pressure between the subscapularis and AIGHL-LC and between the glenoid bone and the AIGHL-LC following Bankart repair. Twenty-two fresh-frozen cadaveric shoulders were used. They were attached to a shoulder-positioning device to which a compression force was applied. Loads applied to the supraspinatus, infraspinatus, and teres minor tendons were held constant. The loads applied to the subscapularis tendon were set at 0, 10, 20, and 30 Newton (N). Contact pressure and area between the subscapularis and the AIGHL-LC were measured with the arm at 4 rotational positions: 60° and 30° internal, neutral, and 30° external. After the Bankart lesion was created, the contact area and pressure between the AIGHL-LC and glenoid bone were measured while Bankart repair was performed with or without loading of the subscapularis. The contact area and pressures with 10, 20, and 30 N of subscapularis loadings were significantly greater than with 0 N of subscapularis loading at 60° internal rotation and 30° external rotation (P < .05). After Bankart repair, contact area and pressure with subscapularis loading between the AIGHL-LC and glenoid bone were significantly greater than without subscapularis loading (P < .01). We conclude that isometric contraction exercises of the subscapularis might facilitate healing of the AIGHL-LC after Bankart repair.

Abstract
Recent studies have reported equivalent outcomes of arthroscopic and open shoulder stabilization. However, surgical strategy for shoulder instability is a challenging and controversial problem for surgeons that have to treat collision sport athletes. In fact, only few studies support the arthroscopic surgery for this group of patients. The aim of this study is to evaluate the outcome of arthroscopic stabilization in a homogenous population of professional young athletes practicing in high-level collision sport. We treated 22 consecutive professional rugby players, with a mean age of 23.6 years, affected by traumatic anterior shoulder instability. All patients underwent arthroscopic Bankart repair with bone suture-anchors. Exclusion criteria were: failed previous shoulder surgery, atraumatic, multidirectional or posterior instability, bone defects greater than 20% of the anterior-inferior glenoid, engaging Hill-Sachs, rotator cuff tears, capsular-ligament avulsion on the humeral side (HAGL). Patients were evaluated according to Constant score, Rowe score and Visual Analogue Scale (VAS) for discomfort and handicap. The mean follow-up was 40.7 months (range, 6 to 87 months). All patients except one were able to return at the same previous sports level at 5 to 6 months postoperatively. Re-dislocation occurred in 3 players for high impact trauma during competition or training. Our results confirm that, also in the collision sport patients, anatomic arthroscopic Bankart repair is a good option for the treatment of traumatic anterior instability without associated lesions. .

Abstract
BACKGROUND Many surgical procedures are intended to return patients to sport early, but it is unknown how realistic these expectations are after shoulder surgery. PURPOSE To determine which of the commonly performed surgical interventions in the shoulder best facilitated return to sport, and which did not, by 6 months postoperatively. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS The study was a retrospective analysis of prospectively collected data from patients who underwent shoulder surgery from a single surgeon over 12 years. To be included, at least 20 patients needed to have undergone that procedure and complete a questionnaire evaluating their shoulder's function preoperatively and 6 months postoperatively. The primary outcome was a change in the response to the question, "What is your current level of sport?" RESULTS A total of 2261 surgical procedures in 13 categories met the inclusion criteria. Capsular release was the only procedure associated with improved patient-reported sporting level at 6 months (d = 0.18 [95% CI, 0.05-0.30]; P = .009). This represented a mean improvement of 41% from the preoperative sporting level. Bankart repair was associated with the greatest decrease in patient-reported sporting level at 6 months (mean decline of 21%) (d = -0.17 [95% CI, -0.34 to -0.01]; P = .034), followed by rotator cuff repair (mean decline of 13%) (d = -0.06 [95% CI, -0.03 to -0.10]; P = .0004). There were no significant changes in sporting level at 6 months postoperatively for rotator cuff repair with acromioplasty, polytetrafluoroethylene (PTFE) patch repair, acromioplasty, superior labral anterior to posterior (SLAP) repair, total shoulder arthroplasty, reverse total shoulder arthroplasty, rotator cuff repair with capsular release, rotator cuff repair with stabilization, calcific debridement, or hemiarthroplasty. CONCLUSION Capsular release was the only surgical procedure that provided a significant improvement in patient-reported sporting level in a relatively short period of time (6 months). Patients who underwent rotator cuff repair and Bankart repair were the only surgical groups that reported a significant decline in sporting level 6 months postoperatively.

Abstract
BACKGROUND In spite of the probable advantages of Bankart repair with modified Mason-Allen technique, there has been no study to evaluate the clinical outcomes of the modified Mason-Allen technique for Bankart repair. PURPOSE To prospectively compare the anatomic and clinical outcomes between the vertical simple stitch and the modified Mason-Allen stitch with respect to the labral height, retear rate, redislocation/apprehension, and various functional outcome scores. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS Patients who underwent arthroscopic Bankart repair with double-loaded suture anchors were randomly allocated to 1 of 2 groups: the vertical simple stitch method (SS; n = 45) or the Bankart repair using modified Mason-Allen technique (BRUMA; n = 41). All patients underwent computed tomography arthrography at 6 months postoperatively and various functional outcome measurements at least 2 years postoperatively. The labral height and width at the 3-, 4-, and 5-o'clock positions were measured preoperatively and at 6 months after surgery on axial computed tomography arthrography; the redislocation/apprehension rate, the retear rate, and various functional outcome scores were evaluated at each follow-up visit. RESULTS Postoperative labral height and width were significantly increased at all locations (all P < .001) in both groups, but they were not statistically different between groups (all P > .05). Two patients in the SS group (4.4%) and 2 in the BRUMA group (4.9%) experienced redislocation after surgery, and 4 patients in the SS group (8.9%) and 2 in the BRUMA group (4.9%) group showed apprehension after surgery. Additionally, 5 patients in the SS group (11.1%) and 2 in the BRUMA group (4.9%) showed retear at 6 months ( P = .239). There were no differences in any functional outcome scores (all P > .05). CONCLUSION There was no difference in the radiologic outcomes at 6 months and the clinical outcomes assessed at least 2 years after surgery between the groups.

Abstract
BACKGROUND The present study aimed to determine whether arthroscopic remplissage with Bankart repair is an effective treatment for improving outcomes for collision athletes with Bankart and non-engaging Hill-Sachs lesions. METHODS Twenty collision athletes underwent arthroscopic Bankart repair with posterior capsulotenodesis (B&R group) and were evaluated retrospectively, using pre- and postoperative WOSI (Western Ontario Shoulder Instability), EQ-5D (EuroQOL five dimensions), EQ-VAS (EuroQol-visual analogue scale) scores and Subjective Shoulder Value (SSV). The recurrence and re-operation rates were compared to a matched group with isolated arthroscopic Bankart repair (B group). RESULTS The mean age was 25 years with an mean follow-up of 26 months. All mean scores improved with SSV of 90%. There was a mean deficit in external rotation at the side of 10°. One patient was treated with hydrodilatation for frozen shoulder. One patient had residual posterior discomfort but no apprehension in the B&R group compared to 5% persistent apprehension in the B group. In comparison, the recurrence and re-operation rates were 5% and 30% (p = 0.015), 5% and 35% (p = 0.005) in the B&R and B groups, respectively. CONCLUSIONS This combined technique demonstrated good outcomes, with lower recurrence rates in high-risk collision athletes. The slight restriction in external rotation does not significantly affect any clinical outcomes and return to play.

Abstract
PURPOSE The restoration of the labrum complex and the influence on secondary osteoarthritis after arthroscopic Bankart repair on magnetic resonance imaging (MRI) remain unclear. METHODS Twenty-one patients were retrospectively followed after unilateral primary arthroscopic Bankart repair with knot-tying suture anchors (8.8 ± 2.5 years after surgery, age 25.3 ± 6.3 years). Bilateral structural MRI was performed to assess labrum-glenoid restoration by measurements of the labrum slope angle, height index, and labrum interior morphology according to the Randelli classification. Osteoarthritic status was bilaterally assessed by a modified assessment based on the Samilson-Prieto classification. RESULTS MRI assessment revealed full labrum-glenoid complex restoration with equivalent parameters for anterior slope angle (mean ± SD: 21.3° ± 2.6° after Bankart repair vs. 21.9° ± 2.6° control) and height index (2.34 ± 0.4 vs. 2.44 ± 0.4), as well as the inferior slope angle (23.1° ± 2.9° vs. 23.3° ± 2.1°) and height index (2.21 ± 0.3 vs. 2.21 ± 0.3) (all n.s.). The labrum morphology showed only for the anterior labrum significant alterations (1.4 ± 0.9 vs. 0.6 ± 0.7, p < 0.05), the inferior labrum occurred similarly (1.3 ± 0.8 vs. 0.8 ± 0.5, n.s.). Osteoarthritic changes were significantly increased after Bankart repair compared to the uninjured shoulder (4.8 ± 5.1 mm vs. 2.5 ± 1.0 mm; p < 0.05), with a significant correlation of osteoarthritis status between both shoulders (p < 0.05). Scores generally decreased after Bankart repair (constant 84.6 ± 9.5 vs. 94.5 ± 4.9 control, p < 0.05; Rowe 84.5 ± 6.5 vs. 96.2 ± 4.2, p < 0.05; Walch-Duplay 82.4 ± 7.0 vs. 94.3 ± 4.0, p < 0.05) with a strong correlation with osteoarthritis status (p < 0.05). CONCLUSIONS Arthroscopic Bankart repair enabled good clinical outcomes and complete quantitative labrum restoration parameters. Next to several well-known parameters, secondary osteoarthritis after arthroscopic Bankart repair significantly correlated with osteoarthritic status of the uninjured contralateral shoulder but was not influenced by quantitative labrum restoration. The recommendation for arthroscopic Bankart repair should be based on clinical parameters and not on prevention of secondary osteoarthritis. STUDY DESIGN Case series. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Recurrent instability is a frequent complication following arthroscopic Bankart repair. The purpose of this study was to investigate risk factors for poor patient-reported clinical outcome scores and failure rates. METHODS Patients who underwent arthroscopic Bankart repair at least 2 years earlier were included. Preoperative and postoperative Single Assessment Numeric Evaluation; Quick Disabilities of the Arm, Shoulder and Hand; American Shoulder and Elbow Surgeons; and satisfaction scores were collected. The relationship of the following factors with outcomes and failure rates was assessed: (1) previous arthroscopic stabilization, (2) 3 or more dislocations prior to surgery, (3) glenoid labral articular disruption (GLAD) lesion, (4) concurrent superior labral anterior-to-posterior tear repair, and (5) concurrent biceps tenodesis. RESULTS The study included 72 patients with a median age of 23 years (range, 14-49 years). Subsequent revision was required in 9 (12.5%); 1 additional patient (1.4%) had recurrent dislocation. Outcome data were available at a median follow-up of 3 years (range, 2-9 years). All scores significantly improved from preoperatively to postoperatively (P <.05); the mean patient satisfaction score was 9, with a median of 10 (range, 1-10). None of the analyzed factors were associated with worse postoperative outcome scores. GLAD lesions were significantly associated with a higher rate of failure (P = .007). No other analyzed factors had a significant association with failure rates (P > .05). CONCLUSIONS Patients with arthroscopic Bankart repair for traumatic anteroinferior shoulder instability had excellent outcomes, even in the context of previous arthroscopic stabilization surgery, 3 or more dislocations prior to surgery, concurrent superior labral anterior-to-posterior tear repair, or concurrent biceps tenodesis. However, GLAD lesions were associated with higher rates of failure, and the presence of a GLAD lesion may herald the presence of changes in the articular version or other as-yet-undetermined factors that could predispose patients to failure.

Abstract
During arthroscopic Bankart-repair the lasso-loop-stitch can be used. The clinical outcome of this technical modification to a broadly used procedure is not known. We followed-up 24 patients treated with this technique over 30 months. We found an excellent clinical outcome in 96% of all cases. The average Rowe-score was 96.3 points. The mean QuickDash was 2.8 points. Using the lasso-loop-stitch in arthroscopic Bankart-repair is safe and results in very good clinical outcomes. It might lead to an accentuated labral bump and enables secure knot-tying with knot-positioning away from the articular cartilage while avoiding the suture cutting through the tissue.

Abstract
BACKGROUND No previously published studies have examined recurrent traumatic incomplete events in patients with excessive joint laxity. The purpose of this study is to investigate outcomes after arthroscopic stabilization for recurrent traumatic shoulder subluxation in patients with excessive joint laxity but no history of dislocation. METHODS This study included 23 patients with glenoid bone defects less than 20% who underwent arthroscopic stabilization of recurrent shoulder subluxation and were available for at least 2 years follow-up. Outcomes were assessed with the subjective shoulder value (SSV), University of California Los Angeles (UCLA) shoulder score, Rowe score, and sports/recreation activity level. RESULTS Postoperatively, overall functional scores improved significantly (p < 0.001), compared to preoperative scores: SSV improved from 49.1 to 90.4; Rowe score improved from 36.7 to 90.2; and UCLA shoulder score improved from 26.3 to 32.5. Patient satisfaction rate was 87% (20/23 patients). Sports/recreation activity level (return to premorbid activity level; grade I = 100% to grade IV = less than 70%) was grade I in 7 patients, grade II in 11, grade III in 3, grade IV in 2. The incidence of any glenoid bone defect was 61% (14/23 patients), and the mean glenoid bone defect size was 8%; among these 14 patients, 8 (35%) exhibited 15-20% glenoid bone defects. Instability reoccurred in 2 patients (9%) who had 15-20% glenoid bone defect. CONCLUSION Despite excessive joint laxity, overall functional outcomes after arthroscopic stabilization of recurrent shoulder subluxation were satisfactory. However, arthroscopic Bankart repair may not be reliable in patients with excessive joint laxity plus a glenoid bone defect size of more than approximately 15%.
