Introduction. The Bankart lesion is the most common form of labro-ligamentous injury in patients with traumatic dislocations of the shoulder. Various methods have been described each with its own advantages and disadvantages. We describe 5-year results of arthroscopic Bankart repair using knotless anchors. Patients and Methods. There were 38 patients, with involvement of the dominant arm in 28 patients. Recurrent dislocation was the most common indication in 21 patients, followed by first dislocation in 9 patients and second dislocation in 8 patients. All patients were done under general anesthesia and regional block in beach-chair position. Standard portals were used and repair done using 2.9 mm pushlock knotless anchors (Arthrex®). Patients had sling for 4 weeks and followed by a strict physiotherapy rehab protocol. Patients were followed up at 6 weeks and 3 monthly thereafter. Results. Only one patient had symptoms of recurrent instability, but was not keen on further surgery. Two patients had limitation of external rotation to 10 degrees. The mean Carter-Rowe score was 77.3. 90% of patients were happy to recommend surgery. Conclusion. Arthroscopic Bankart repair appears to produce good mid-term results for patients with shoulder instability

Previously, we conducted a multi-center, double-blinded randomized controlled trial comparing arthroscopic Bankart repair with and without remplissage. The end point for the randomized controlled trial was two years post-operative, providing support for the benefits of remplissage in the short term in reducing recurrent instability. The aim of this study was to compare the medium term (3 to 9 years) outcomes of patients previously randomized to have undergone isolated Bankart repair (NO REMP) or Bankart repair with remplissage (REMP) for the management of recurrent anterior glenohumeral instability. The rate of recurrent instability and instances of re-operation were examined. The original study was a double-blinded, randomized clinical trial with two 1:1 parallel groups with recruitment undertaken between 2011 and 2017. For this medium-term study, participants were reached for a telephone follow-up in 2020 and asked a series of standardized questions regarding ensuing instances of subluxation, dislocation or reoperation that had occurred on their shoulder for which they were randomized. Descriptive statistics were generated for all variables. “Failure” was defined as occurrence of a dislocation. “Recurrent instability” was defined as the participant reporting a dislocation or two or more occurences of subluxation greater than one year post-operative. All analyses were undertaken based on intention-to-treat whereby their data was analyzed based on the group to which they were originally allocated. One-hundred and eight participants were randomized of which 50 in the NO REMP group and 52 in the REMP group were included in the analyses in the original study. The mean number of months from surgery to final follow-up was 49.3 for the NO REMP group and 53.8 for the REMP group. The rates of re-dislocation or failure were 8% (4/52) in the REMP group at an average of 23.8 months post-operative versus 22% (11/50) in the NO REMP at an average of 16.5 months post-operative. The rates of recurrent instability were 10% (5/52) in the REMP group at an average of 24 months post-operative versus 30% (15/50) in the NO REMP group at an average of 19.5 months post-operative. Survival curves were significantly different favouring REMP in both scenarios. Arthroscopic Bankart repair combined with remplissage is an effective procedure in the treatment of patients with an engaging Hill-Sachs lesion and minimal glenoid bone loss (<15%). Patients can expect favourable rates of recurrent instability when compared with isolated Bankart repair at medium term follw-up

The aim of this study was to evaluate prospectively the outcome following arthroscopic Bankart repair using two types of suture anchors, absorbable and non-absorbable. Patients with a diagnosis of recurrent traumatic anterior instability of the shoulder, seen between April 2000 and June 2003 in a single unit, were considered for inclusion in the study. Patients were assessed pre-operatively and post-operatively using a subjective patient related outcome measurement tool (Oxford instability score), a visual analogue scale for pain and instability (VAS Pain and VAS instability) and a quality of life questionnaire (SF-12). The incidence of recurrent instability and the level of sporting ability were recorded. Patients were randomised to undergo surgical repair with either non-absorbable or absorbable anchors. 130 patients were included in the study. 6 patients were lost to follow-up and 124 patients (95%) completed the study. Both types of anchors were highly effective. There were no differences in the rate of recurrence or any of the scores between the two. Four patients in the non-absorbable group and 3 in the absorbable group experienced further episodes of dislocation after a traumatic event. The rate of redislocation in the whole series was therefore, 5.6%. In addition, 4 patients, all of them in the absorbable group (4%) described ongoing symptoms of instability but no true dislocations. 85% of the patients have returned to their previous level of sporting activity. There are no differences in the outcome of Arthroscopic Bankart repair using either absorbable or non-absorbable anchors. Both are highly effective, showing a redislocation rate of 5.6%

Currently there is no standard quantitative methodology for the description of Hill-Sachs defects (HSD), the size of which is important in planning surgical treatment for patients with anterior shoulder instability. The main purpose was to develop a simple imaging measurement to improve communication regarding HSDs. The secondary goal was to determine, using this new measurement, whether there was a significant difference in the size of HSDs in patients who underwent a Weber osteotomy (more invasive surgical intervention for those failing Bankart repair) compared with patients who underwent clinically successful arthroscopic Bankart repairs (the first surgical intervention for anterior shoulder instability). HSD volume was calculated with newly developed methodology using computed tomography in ten patients who required eleven Weber osteotomies and using magnetic resonance imaging in twenty-two patients who had clinically successful arthroscopic Bankart repairs. Within the Weber cohort, regression analysis was performed to determine correlation between HSD volume and each of height, maximum depth, and width. Student's t-test analysis was used to compare HSD volume between the Weber and Bankart cohorts. In the Weber cohort, there is a statistically significant correlation between the HSD Volume Ratio and the HSD Maximum Depth Ratio (R. 2. =0.83). The t-test comparison of mean HSD Volumes showed statistically significant (p<0.0015) larger HSD's in the Weber cohort than the Bankart cohort. HSD depth is a radiological indicator for HSD volume. This simple measurement may facilitate orthopaedic pre-operative planning for patients with severe recurrent anterior shoulder instability. In this preliminary study, patients who had Weber osteotomies after failed Bankart repairs had statistically significantly larger HSDs than patients with clinically successful Bankart repairs

Recurrent anterior shoulder instability (RASI) is related to progressive bone loss on the glenoid and on the humeral head. Bone deficit magnitude is a well-recognized predictor of recurrence of instability after an arthroscopic Bankart surgery, but the best way to measure it is unknown. In this study, we want to determine which measurement method is the best predictor of recurrence of instability and function. For 10 years now, all patients undergoing surgery for RASI in 4 centers are included in a prospective study: the LUXE cohort. Patients with a pre-operative CT-scan and a minimum of 1-year follow-up were included. ISIS score was used to stratify patients. WOSI and Quick-Dash questionnaires were used to characterise function. Bone defects were assessed using the Clock method, the Glenoid Ratio, the Humeral Ratio, the Glenoid Track method and the angle of engagement in the axial plane. A total of 262 patients are now included in the LUXE study. One hundred and three patients met the inclusion criteria for analysis with a majority of male (79%) and a mean age is 28 years old. The median number of dislocations prior to surgery was 6. Seventy patients had an arthroscopic Bankart repair and 33 patients underwent an open Latarjet procedure. The ISIS score for these groups were of 2.7 and 4.8 respectively (p<0.001). The mean bone defect on the glenoid was of 1h51 with the Clock method (range: 0h-4h48; SD=1h46) and of 9% for the glenoid ratio (0–37%, 10%). On the humeral side, the bone defect was of 1h59 (0h-4h08; 0h49) for the Humeral clock method, 15% (0–36%; 6%) with the ratio method and 71 degrees of external rotation (SD=30 degrees) with the angle of engagement measurement. On the combined evaluations, 53 patients presented an off-track lesion, with mean combined hours of 3h53 (SD= 2h13). The greatest correlation obtained was between the glenoid ratio and the glenoid clock method (r=0.919, p<0.001). Eighteen patients had a recurrence of shoulder dislocation after the initial surgery, leading to a recurrence rate of 23% in arthroscopic surgery versus six percent after a Latarjet (OR= 4.6, p=0.034). No bone defect was correlated to Latarjet failure. For the arthroscopic group, the risk of recurrence was related to a smaller angle of engagement of the Hill-Sachs (p=0.05), a smaller Humeral clock measurement (p=0.034) and a longer follow-up (p=0.006). No glenoid or combined measurements were correlated with arthroscopic procedure failure. Recurrence of dislocation was associated to worst function according to the WOSI (1036 vs 573, p=0.002) and DASH (32 vs 15, p=0.03). Even with lower ISIS score, arthroscopic procedures are still leading to high risk of recurrence in this “all comer” consecutive cohort study AND it is related to humeral side parameters. Recurrence is also affecting daily function and creating higher anxiety related to the shoulder


Concepts in glenoid tracking and treatment strategies of glenoid bone loss are well established. Initial observations in our practice in Singapore showed few patients with major bone loss requiring glenoid reconstructions. This led us to investigate the incidence of and the extent of bone loss in our patients with shoulder instability. Our study revealed bony Bankart lesions were seen in 46% of our patients but glenoid bone loss measured only 6–10% of the glenoid surface. In the same study we found that arthroscopic labral repair with capsular plication and Mason-Ellen suturing (Hybrid technique) was sufficient to stabilise patients with bipolar bone defects and minor glenoid bone loss. This led us to develop the concept of minor bone loss and a new algorithm. Our algorithm and strategies to deal with major bone loss will also be discussed, and techniques & outcomes of Arthroscopic Bony Bankart repair, Arthroscopic Glenoid Reconstruction and Arthroscopic Remplissage procedures will be shown

Background:. Individuals with large Hill-Sachs lesions may be prone to failure and reoccurrence following standard arthroscopic Bankart repair. Here, the Remplissage procedure may promote shoulder stability through infraspinatus capsulo-tenodesis directly into the lesion. Little biomechanicaldata about the Remplissage procedure on glenohumeral kinematics, stability, and range of motion (ROM) currently exists. Questions/purposes:. What are the biomechanical effects of Bankart and Remplissage repair for large Hill-Sachs lesions?. Methods:. Six cadaveric shoulders were tested using a custom shoulder testing system. ROM and glenohumeral translation with applied loads in anterior-posterior (AP) and superior-inferior (SI) directions were quantified at 0° and 60° gleno-humeral abduction. Six conditions were tested: intact, Bankart lesion, Bankart with 40% Hill-Sachs lesion, Bankart repair, Bankart repair with Remplissage, and Remplissage repair alone. Results:. Humeral external rotation (ER) and total range of motion (TR) increased significantly from intact after the creation of the Bankart lesion at both 0° abduction (ER +27.0°, TR +35.8°, p < 0.05) [Fig 1] and 60° abduction (ER +9.5°, TR +30.7°, p < 0.05) [Fig 2], but did not increase further with the addition of the Hill-Sachs lesion. The Bankart repair restored range of motion to intact values 0° abduction at addition of the Remplissage repair did not significantly alter range of motion from the Bankart repair alone. There were no significant changes in AP or SI translation between Bankart repair with and without Remplissage compared to the intact specimen. Conclusions:. The addition of the Remplissage procedure for treatment of large Hill-Sachs lesions had no statistically significant effect on ROM or translation for treatment for large Hill-Sachs lesions. Clinical Relevance: The Remplissage technique may be a suitable option for engaging Hill-Sachs lesions. Further clinical studies are warranted

Michael Robinson has been a Consultant Orthopaedic Surgeon and Senior Lecturer in the Department of Orthopaedics and Traumatology in Edinburgh, Scotland, United Kingdom for 10 years. His special interests include the treatment of proximal humeral and clavicle fractures, and shoulder instability. Primary traumatic anterior dislocations of the glenohumeral joint in young adults are common injuries, which are associated with persistent deficits of shoulder function and a high risk of recurrent instability. Although several risk factors have been implicated, a younger age at the time of the primary dislocation, and male gender, are the factors that have been most consistently associated with a higher risk of recurrence. Recent studies have suggested that primary arthroscopic repair of the anteroinferior detachment of the glenoid labrum (Bankart repair) may reduce the risk of subsequent recurrent instability and improve function, when compared with non-operative treatment. However, the unblinded or single-blind design of these studies fails to eliminate the potential for error due to observer or subject bias, and the therapeutic effects of the Bankart repair cannot be distinguished from those of the arthroscopic examination and washout alone. The latter may reduce the rate of subsequent instability, by promoting healing of the labral detachment, or by altering the patient's subsequent level of physical activity and compliance with rehabilitation protocols. A clinical trial conducted recently in our Institution assessed the efficacy of a primary arthroscopic stabilisation after a first-time dislcoation, whilst controlling for the therapeutic effects of the arthroscopic examination and washout alone. We aimed to specifically test the null hypothesis, that an arthroscopic Bankart repair (ABR) would not produce an improvement in the rate of recurrent instability, functional outcome, range of movement, levels of patient satisfaction or total cost of treatment, when compared with an arthroscopic examination and washout (AWO) alone. The results of this study will be presented, together with an overview of the advantages and disadvantages of primary arthroscopic stabilisation. None of the authors have received any payment or consideration from any source for the conduct of this study

Recurrent shoulder instability in those with bony defects is a difficult surgical problem to resolve. Burkhart and De Beer described an unacceptably high recurrence rate for arthroscopic Bankart repair in the presence of an inverted-pear glenoid with or without an engaging Hill-Sachs lesion, with suggestions that an open modified Latarjet procedure should be recommended in such patients. The Congruent-Arc Latarjet is a modification of the Latarjet open bony stabilisation for shoulder instability developed by Burkhart and De Beer. It involves rotation of the coracoid so the curved under-surface lies congruent with the glenoid. At the Royal Derby Hospital, UK, this procedure has been adopted by our four shoulder surgeons, two of whom undertook fellowship training with De Beer, we studied the outcomes of the patients who had undergone the modified Congruent-Arc Latarjet procedure in our department. Fifty-two consecutive patients were identified over a five-year period at the Royal Derby Hospital or Derbyshire Royal Infirmary between 2006 and 2010 inclusive. With the approval of the clinical audit department, the data was collected using theatre records and clinical coding information to identify the patient group. A review of the case notes and local PACS system was undertaken to establish pre and post-operative examination findings, radiology findings regarding Hill-Sachs defects and glenoid bone loss, re-dislocation rates and post-operative function with return to normal activity. The endpoints of this study were aimed at finding out whether patients did return to normal function, were able to continue doing activity that would have provoked dislocation prior to surgery, and how many of the cases re-dislocated. No surgeon consultant had a patient who re-dislocated after this procedure. The follow-up period was from 1 year to 6 years post-operatively. The complications of this procedure were found to be the dislodgement of bone anchors in 2 patients, who required further arthroscopy to remove the suture anchor from the gleno-humeral joint. One patient had prolonged functionally limiting loss of external rotation, which resolved after intensive physiotherapy at 7 months follow up. We will provide graphical representation of the pre and post operative functional scores. We have demonstrated that the Congruent-Arc Latarjet is a reproducible procedure in the hands of surgeons other than the original authors, particularly when comparing our current 0% re-dislocation rate with the published literature, which suggests that 3.9% of patients undergoing this procedure with greater than 25% bone loss of the glenoid or an engaging Hill-Sachs will re-dislocate post-operatively, and this is better than the 6% re-dislocation rate of the standard Bristow-Latarjet procedure

Coracoid fractures during screw insertion and graft osteolysis are serious concerns with standard screw fixation techniques in Latarjet procedure. This study tends to evaluate the outcome of mini open Latarjet using Arthrex mini-plate for coracoids graft fixation. We did retrospective analysis of 30 patients with recurrent anterior shoulder instability after arthroscopic Bankart's repair. A low profile wedge plate (Arthrex) with two low profile screws was used for fixation of the coracoid graft. CT analysis was performed at final follow up to see graft union and results were evaluated using American shoulder and elbow score (ASES) and Western Ontario shoulder instability score (WOSIS). Mean follow up time was 24 months. Postoperatively, mean forward elevation was 162.8 degrees and external rotation was 44.6 degrees. All patients returned to their previous occupation. None reported to be having any recurrent subluxation post-surgery. The mean ASES score was 92.5 while the mean WOSIS score was 76.84%. Only one patient had screw backing out from the plate. There was no case of coracoid graft osteolysis. The mini-open Latarjet procedure with graft fixation with Arthrex mini-plate provides satisfactory outcome and stabilization in patients who present with dramatic bone loss and failed soft tissue reconstruction. It not only ensures early rehabilitation but also minimum loss of external rotation. The only drawback is the relatively high cost of the implant
