Abstract Objective The open Bristow procedure is a long established and effective method for treating anterior shoulder instability. Following the trends of minimally-invasive surgeries, these procedures were performed arthroscopically, and their outcomes were evaluated. Methods A total of 43 shoulders of patients submitted to Bristow procedures by arthroscopy, using a graft positioned horizontally and a screw, with at least two years of postoperative follow-up, were evaluated regarding quality of life, de novo dislocation index, and loss of lateral rotation. Results The mean follow-up time was of 76 months (range: 129 to 24 months). The University of California at Los Angeles (UCLA) score varied from 25.56 ± 0.50 (standard deviation [SD] = 3.25) to 33.23 ± 0.44 (SD = 2.91) (p < 0.0001). Two or more years after surgery, the mean Rowe score was of 94.25 ± 1.52 (SD = 1.34), whereas the good results standard is 75 (p < 0.0001). The mean value for the simple shoulder test was of 11.35 ± 0.21 (SD = 1.34), while the mean value of the lateral rotation loss was of 10.37° ± 1.36° (SD = 8.58°). There were no de novo dislocations.In total, there were 12 complications, 8 of which had no clinical repercussions. The clinically-significant complications included an infection six months after surgery with a potential hematogenous origin, a coracoid fracture that required an intraoperatively procedure change, and two patients with previous impingement who required synthesis material removal more than six months after surgery. Conclusion Although the arthroscopic Bristow procedure was effective in treating anterior shoulder instability, it is not a complication-free surgery.

The Mean

Objectives The two most common surgical interventions for recurrent anterior shoulder instability include arthroscopic Bankart repair and the Latarjet procedure. However, indications for each procedure remain debated between surgeons with 90% of surgeons (except French surgeons) preferring soft tissue Bankart repair initially. It remains unclear whether the results of a Latarjet procedure performed after a failed arthroscopic Bankart repair differ from those performed for primary cases. The purpose of our study was to compare the postoperative outcomes of patients who had undergone a Latarjet as a primary surgery versus those who had had a Latarjet as revision surgery for a failed arthroscopic Bankart repair Methods Patients who had undergone open or arthroscopic Latarjet procedure between 2003 and 2015 in 5 fellowship-trained surgical practices were included. Charts were retrospectively reviewed to identify patients who had undergone a primary Latarjet or those who had had a Bankart repair prior to the Latarjet. Age, ISIS score, BMI, sports activity, hyperlaxity and delay before surgery were retrospectively collected. Outcome measures were prospectively collected, including range of motion, SSV, Walch-Duplay, scores, recurrence of instability, apprehension or new surgery. Results A total of 311 patients were included. 28% of the patients were lost to follow-up and the mean follow-up was 3.4 years +/-0.8. There were 21 patients who had had a Bankart repair prior to the Latarjet procedure. Both populations were comparable regarding preoperative data. The postoperative instability rate was 3% in the overall population; 4.8% in the “primary Latarjet” group and 2.3% in the ”Latarjet for failed Bankart” group. This difference was not significant (p=0.50). However, the mean Walch-Duplay score was significantly lower and the pain scores significantly higher in patients who had had a prior Bankart repair: 51.9 +/- 25 versus 72.1 +/- 25.2 and 2.5/10 versus 1.2/10 respectively. The Simple Shoulder Test was comparable in both groups. Conclusion The study confirms that the Latarjet is an effective procedure to treat primary chronic anterior instability and also to stabilize a shoulder after a failed Bankart repair. However, the thought that a Bankart repair does not “burn any bridges” appears to be incorrect relative to postoperative pain and functional scores in the setting of future Latarjet procedure.

Female Patients

Background: Nearly all studies describing shoulder stabilization focus on male patients. Little is known regarding the clinical outcomes of female patients undergoing shoulder stabilization, and even less is understood about females with glenoid bone loss. Purpose: To assess the clinical outcomes of female patients with recurrent anterior shoulder instability treated with the Latarjet procedure. Study Design: Case series; Level of evidence, 4. Methods: All cases of female patients who had recurrent anterior shoulder instability with ≥15% anterior glenoid bone loss and underwent the Latarjet procedure were analyzed. Patients were evaluated after a minimum 2-year postoperative period with scores of the American Shoulder and Elbow Surgeons form, Simple Shoulder Test, and pain visual analog scale. Results: Of the 22 patients who met our criteria, 5 (22.7%) were lost to follow-up, leaving 17 (77.2%) available for follow-up with a mean ± SD age of 31.7 ± 12.9 years. Among these patients, 16 (94.1%) underwent 1.6 ± 0.73 ipsilateral shoulder operations (range, 1-3) before undergoing the Latarjet procedure. Preoperative indications for surgery included recurrent instability with bone loss in all cases. After a mean follow-up of 40.2 ± 22.9 months, patients experienced significant score improvements in the American Shoulder and Elbow Surgeons form, Simple Shoulder Test, and pain visual analog scale ( P < .05 for all). There were 2 reoperations (11.8%). There were no cases of neurovascular injuries or other complications. Conclusion: Female patients with recurrent shoulder instability with glenoid bone loss can be successfully treated with the Latarjet procedure, with outcomes similar to those of male patients in the previously published literature. This information can be used to counsel female patients with recurrent instability with significant anterior glenoid bone loss.

Background: Recent studies have demonstrated equivalent short-term results when comparing arthroscopic versus open anterior shoulder stabilization. However, none have evaluated the long-term clinical outcomes of patients after arthroscopic or open anterior shoulder stabilization, with inclusion of an assessment of preoperative glenoid tracking. Purpose: To compare long-term clinical outcomes of patients with recurrent anterior shoulder instability randomized to open and arthroscopic stabilization groups. Additionally, preoperative magnetic resonance imaging (MRI) studies were used to assess whether the shoulders were “on-track” or “off-track” to ascertain a prediction of increased failure risk. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Follow-up assessments were performed at minimum 15-year follow-up using established postoperative evaluations. Clinical failure was defined as any recurrent dislocation postoperatively or subjective instability. Preoperative MRI scans were obtained to calculate the glenoid track and designate shoulders as on-track or off-track. These results were then correlated with the patients’ clinical results at their latest follow-up. Results: Of 64 patients, 60 (28 arthroscopic and 32 open) were contacted or examined for follow-up (range, 15-17 years). The mean age at the time of surgery was 25 years (range, 19-42 years), while the mean age at the time of this assessment was 40 years (range, 34-57 years). The rates of arthroscopic and open long-term failure were 14.3% (4/28) and 12.5% (4/32), respectively. There were no differences in subjective shoulder outcome scores between the treatment groups. Of the 56 shoulders, with available MRI studies, 8 (14.3%) were determined to be off-track. Of these 8 shoulders, there were 2 surgical failures (25.0%; 1 treated arthroscopically, 1 treated open). In the on-track group, 6 of 48 had failed surgery (12.5%; 3 open, 3 arthroscopic [ P = .280]). Conclusion: Long-term clinical outcomes were comparable at 15 years postoperatively between the arthroscopic and open stabilization groups. The presence of an off-track lesion may be associated with a higher rate of recurrent instability in both cohorts at long-term follow-up; however, this study was underpowered to verify this situation.

Tissue Stabilization

Objectives: Surgical options for shoulder instability in collision athletes remain controversial. Although arthroscopic soft tissue stabilization is widely accepted treatment for traumatic anterior shoulder instability, many surgeons prefer coracoid transfer such as Latarjet procedure for collision athletes with or without glenoid defect due to potential high recurrence rate after arthroscopic soft tissue Bankart repair (ABR). In the meantime, Hill-Sachs remplissage (HSR) has been gaining popularity as an effective arthroscopic augmentation procedure. Since 2002, we performed rotator interval closure (RIC) as an augmentation in addition to ABR or arthroscopic bony Bankart repair (ABBR) for collision athletes and obtained satisfactory outcome. However, teen players demonstrated higher recurrence rate compared to twenties and thirties. Therefore, from 2012, we performed HSR as an additional augmentation for teen players besides ABR/ABBR and RIC. The purpose of this study was to assess the outcomes after arthroscopic stabilization in collision athletes who underwent shoulder stabilization under our treatment strategy. Methods: Between 2012 through 2015, 95 consecutive collision athletes underwent shoulder stabilization. Among those, only 2 patients (2%) underwent arthroscopic bony procedure for poor capsular integrity. Among the remaining 93 patients who underwent soft tissue stabilization, 65 were available for minimum 2-year follow-up (70%). Therefore, subjects consisted of 65 players including 54 rugby and 11 American football players (Table 1). There were 13 national top league, 24 collegiate, 21 junior or senior high school, and 7 recreational players. The mean age at surgery was 20 years (range, 16-36). The mean follow-up was 37 months (range, 24-64). We retrospectively reviewed intraoperative findings and surgical procedures using patient records including surgical reports and videos. We also investigated functional outcome and recurrence rate. Pre- and postoperative Rowe scores were compared using paired t test. Results: Preoperative 3DCT of the glenoid demonstrated bony Bankart (fragment type) in 43 players (66%), attritional type in 16 (25%), and normal glenoid in 6 (9%). Mean glenoid bone loss was 15% (range, 0-25) and all of the glenoid with more than 10% bone loss retained bony fragment. All 65 players demonstrated Bankart lesion and 15 had concomitant SLAP lesion (23%) which required to be repaired. In addition, 5 players demonstrated capsule tear (8%), which were also repaired. Twenty-four players (36%) underwent ABR or ABBR with RIC and forty one players (64%) underwent ABR or ABBR combined with HSR (Table 1). The mean Rowe score significantly improved after surgery from 65 (range, 55-75) to 92 (range, 65-100) (P < .001). Recurrence appeared in 2 cases (3%), both of which were junior or senior high school players who underwent ABR with HSR. Ten national top league players who underwent ABR with RIC had no recurrence. Conclusion: Soft tissue stabilization combined with selective augmentation procedures for traumatic shoulder instability in collision athletes demonstrated satisfactory outcomes with extremely low recurrence rate. Since the incidence of having bony Bankart lesion in collision athletes was very high, arthroscopic bony Bankart repair worked in many patients even with significant glenoid bone loss. Further, Hill-Sachs remplissage seemed to be effective additional augmentation especially in young collision athletes. [Table: see text]

Background and Objectives: The all-arthroscopic Latarjet (aL) procedure was introduced to manage recurrent shoulder instability. Our study aimed to report the outcomes of aL procedures with the Rowe, University of California-Los Angeles (UCLA), simple shoulder test (SST) scores, and range of motion (ROM) in external rotation at a minimum follow-up of 2 years. Material and Methods: A total of 44 patients presenting recurrent shoulder instability were managed with aL procedure. Clinical outcomes were assessed at a mean follow-up of 29.6 ± 6.9 months. The postoperative active ROM was measured and compared with the contralateral shoulder. The Rowe, UCLA, and SST scores were administered preoperatively and postoperatively. Results: No patients experienced infections or neuro-vascular injuries. Seven (15%) patients required revision surgery. After surgery, the external rotation was statistically lower compared to the contralateral shoulder, but it improved; clinical outcomes also improved in a statistically significant fashion. Conclusions: The aL produced good results in the management of recurrent shoulder instability, but the complication rate was still high even in the hands of expert arthroscopist.

Background: It remains unclear whether results differ between a Latarjet procedure performed after a failed arthroscopic Bankart repair and one performed as the primary operation. Purpose: To compare the postoperative outcomes of the Latarjet procedure when performed as primary surgery and as revision for a failed arthroscopic Bankart repair. Study Design: Cohort study; Level of evidence, 3. Methods: A multicenter retrospective comparative case-cohort analysis was performed for all patients undergoing a Latarjet procedure for recurrent anterior shoulder instability. Patients were separated into 2 groups depending on if the Latarjet procedure was performed after a failed arthroscopic Bankart repair (group 1) or as the first operation (group 2). Outcome measures included recurrent instability, reoperation rates, complications, pain, Walch-Duplay scores, and Simple Shoulder Test. Results: A total of 308 patients were eligible for participation in the study; 72 (23.4%) did not answer and were considered lost to follow-up, leaving 236 patients available for analysis. Mean follow-up was 3.4 ± 0.8 years. There were 20 patients in group 1 and 216 in group 2. Despite similar rates of recurrent instability (5.0% in group 1 vs 2.3% in group 2; P = .5) and revision surgery (0% in group 1 vs 6.5% in group 2; P = .3), group 1 demonstrated significantly worse pain scores (2.56 ± 2.7 vs 1.2 ± 1.7; P = .01) and patient-reported outcomes (Walch-Duplay: 52 ± 25.1 vs 72.2 ± 25.0; P = .0007; Simple Shoulder Test: 9.3 ± 2.4 vs 10.7 ± 1.9; P = .001) when compared with those patients undergoing primary Latarjet procedures. Conclusion: Functional outcome scores and postoperative pain are significantly worse in patients undergoing a Latarjet procedure after a failed arthroscopic Bankart repair when compared with patients undergoing primary Latarjet. The assumption that a failed a Bankart repair can be revised by a Latarjet with a similar result to a primary Latarjet appears to be incorrect. Surgeons should consider these findings when deciding on the optimal surgical procedure for recurrent shoulder instability.

Background Recent literature has demonstrated that the success rates of arthroscopic stabilization of glenohumeral instability deteriorate in patients with an anteroinferior glenoid bone deficiency, also known as the “inverted pear” glenoid. Purpose This study was conducted to assess the outcomes of arthroscopic stabilization for recurrent anterior shoulder instability in patients with a mean anteroinferior glenoid bone deficiency of 25% (range, 20%-30%). Study Design Cohort study; Level of evidence, 3. Methods Twenty-one of 23 patients (91% follow-up) undergoing arthroscopic stabilization surgery and noted to have a bony deficiency of the anteroinferior glenoid of 20% to 30% were reviewed at a mean follow-up of 34 months (range, 26-47). The mean age was 25 years (range, 20-34); 2 patients were female and 19 were male. All patients were treated with a primary anterior arthroscopic stabilization using a mean of 3.2 suture anchors (range, 3-4). Eleven patients had a bony Bankart that was incorporated into the repair; 10 had no bone fragment and were considered attritional bone loss. Outcomes were assessed using the Rowe score, the American Shoulder and Elbow Surgeons (ASES) Score, the Single Assessment Numeric Evaluation (SANE), and the Western Ontario Shoulder Instability (WOSI) Index. Findings of recurrent instability and dislocation events were documented. Results Two patients (9.5%) experienced symptoms of recurrent subluxation, and 1 (4.8%) sustained a recurrent dislocation that required revision open surgery. The mean postoperative outcomes scores were as follows SANE = 88.1 (range, 65-100; standard deviation [SD] 9.0); Rowe = 85.2 (range, 55-100; SD 14.1); ASES Score = 93.1 (range, 78-100; SD 5.3); and WOSI Index = 398 (82% of normal; range, 30-1175; SD 264). No patient with a bony fragment experienced a recurrent subluxation or dislocation, and mean outcomes scores for patients with a bony fragment were better than those with no bony fragment (P = .08). No patient required medical discharge from the military for his or her shoulder condition. Conclusions Arthroscopic stabilization for recurrent instability, even in the presence of a significant bony defect of the glenoid, can yield a stable shoulder; however, outcomes are not as predictable especially in attritional bone loss cases. Longer-term follow-up is needed to see if these results hold up over time.

Background: The Latarjet procedure is used to treat recurrent anterior shoulder instability in patients with bony glenoid loss and/or failed previous stabilisation surgery. It has reportedly high success rates, but recent publications have reported concerns of high complication rates. This study aims to assess the complications and outcomes of the Latarjet procedure in our institution, with a minimum 2-year follow-up and compared it to the current literature. Methods: Patients who underwent the procedure over a 36-month period were included in this study (n=81). Seventy-three (90%) patients in our cohort competed in amateur to professional level sports. The indications for surgery were recurrent instability with associated bony glenoid deficiency and/or previous failed arthroscopic stabilisations. The Oxford Shoulder Instability, Constant Shoulder and QuickDASH scores were recorded pre- and post-operatively, along with post-operative complications and failures. Results: Eight (9.9%) complications were recorded: three re-dislocations, two deep infections, one haematoma, one screw breakage and one case of biceps tendinopathy. The mean pre-operative Oxford Shoulder Instability Score improved from 23.2 ± 10.1 to 37 ± 9.2 following the procedure. The mean Constant Shoulder and quickDASH scores also improved from 55.1 ± 21.2 and 30.3 ± 24.3 to 88.1 ± 9.2 and 17.7 ± 23.5 respectively. 98.6% of the patients returned to their pre-injury level of sports. Conclusion: From this study it can be concluded the Latarjet procedure is an effective surgical treatment for recurrent anterior shoulder instability associated with bony glenoid loss, even in high contact professional athletes. Complication rates are lower than previous recent studies have stated.

Background: Although numerous studies have reported on the redislocation rate and functional results of arthroscopic treatment for anterior shoulder instability in athletes, they have not disclosed outcomes in the high-risk group of elite handball players. Purpose: To investigate the postoperative outcomes of arthroscopic treatment for anterior shoulder instability as well as the return-to-sport (RTS) rate in professional handball players. Study Design: Case series; Level of evidence, 4. Methods: Involved in this study were 44 competitive handball players (47 shoulders) who underwent arthroscopic anterior capsulolabral reconstruction between 2010 and 2018 and had a minimum follow-up of 24 months. After surgery, patients completed a questionnaire that collected Rowe and American Shoulder and Elbow Surgeons (ASES) scores and RTS data, and we compared these results with their preoperative scores. We also compared results according to the following subgroups: true dislocations versus recurrent subluxations, younger (<20 years) versus older (≥20 years) age, male versus female sex, and shorter versus longer duration of instability. Statistical analysis included the paired-samples t test and nonparametric Fisher exact test. Results: The mean follow-up period was 52.2 ± 21.4 months. There were 4 shoulders (9%) with recurrent instability. There were significant preoperative to postoperative improvements in the mean Rowe score (from 45.2 to 91.8) and mean ASES score (from 70.6 to 95.7) ( P < .001 for both). Overall, the RTS rate was 83%, and 64% (30/47 shoulders) were able to return to their preinjury level. The RTS rate was significantly lower in the younger players than in the older players (46% vs 86%, respectively; P = .005). Conclusion: The study results indicated that handball players with anterior shoulder instability can be treated using arthroscopic labral reconstruction successfully and 83% of the athletes were able to RTS activity. The handball players aged ≥20 years returned to their preinjury level of sport at a higher rate than did those aged <20 years.

Glenoid Reconstruction

Background: The all-arthroscopic anatomic glenoid reconstruction technique using a distal tibial allograft avoids damage to the subscapularis muscle and allows repair of the capsulolabral tissue. Purpose: To analyze the clinicoradiologic outcomes of patients who underwent this procedure to treat anterior shoulder instability with glenoid bone loss with a minimum 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: Over 6 years, 73 patients (52 male and 21 female; mean age, 28.8 years) under the care of the same surgeon underwent arthroscopic stabilization with capsulolabral Bankart repair and bony allograft augmentation of the glenoid for recurrent shoulder instability with significant bone loss. Pre- and postoperative patient-reported functional assessment was performed using 2 questionnaires, the Western Ontario Shoulder Instability Index (WOSI) and the Disabilities of the Arm, Shoulder and Hand, and radiological assessment was performed using radiographs and computed tomography scans obtained preoperatively and approximately 1 year later (mean ± SD, 0.9 ± 1.1 years). Results: The mean follow-up was 4.7 ± 1.1 years. The mean pre- and postoperative WOSI scores were 71.1 ± 17.5 and 25.6 ± 21.9, respectively ( P < .001). There were no recurrences of dislocation, although 1 patient had symptoms of subluxation; however, 5 patients had hardware complications that required screw removal. There were no cases of nerve injury. Postoperative computed tomography scans were available for 66 patients. Seven patients were lost to follow-up. The graft union rate was 100%. Overall, graft resorption was <50% in 86% of patients (57/66). Eighteen patients (27%) had no resorption (grade 0), 39 (59%) had <50% (grades 1 and 2), and 9 (14%) had ≥50% (grade 3); however, none had symptoms of instability. The mean alpha angle of the screw between the screw shaft axis and the native glenoid axis was 18.3°± 5.7°. Graft positioning was flush with the glenoid in 61 of 66 patients (92.4%), and vertical positioning was excellent in 64 of 66 patients (97.0%) (3- to 5-o’clock position). Conclusion: Arthroscopic stabilization using distal tibial allograft augmentation resulted in excellent clinicoradiologic outcomes at a 2-year follow-up. This procedure has the advantages of being an anatomic reconstruction that addresses bony and soft tissue instability. However, long-term follow-up studies are necessary for better assessment of outcomes.
