Clinical Trial Summary

The primary objective of the study is to evaluate the functional shoulder recovery of patients with recurrent shoulder dislocations at 24 months when treated with either arthroscopic capsuloligamentous repair (Bankart Procedure +/- Remplissage) or coracoid transfer (Latarjet procedure).

Clinical Trial Description

Background: Shoulder is a highly mobile joint with the most directional range of movement compared to other joints in the body. Thus, the surrounding supporting structures of the shoulder joint compromise on the stability of the joint, in order to accomplish this wide range of motion. Anterior dislocations, the most common type of shoulder dislocation, are often complicated by instability, and repeated dislocations. Shoulder instability results in pain and negatively impacts quality of life. Several long-term studies have demonstrated a relationship between the repeated dislocations and the risk of arthritis. Surgical stabilization of the shoulder improves function and may reduce the risk of developing degenerative arthritis. Two procedures are commonly performed in patients with repeated dislocations: a bony transfer procedure (Latarjet) or a soft tissue procedure (Bankart + Remplissage). The Latarjet procedure involves transferring bone to the front of the shoulder. The Bankart + Remplissage procedure involves tightening the soft tissues at the front of the shoulder joint. Although retrospective clinical studies have suggested a reduced recurrence rate with the Latarjet procedure, there is a higher reported complication rate and potential morbidity associated with the open procedure. Several case series from high-volume surgeons in Europe have suggested the Latarjet repair to be an acceptable and potentially favorable surgical approach for all cases of recurrent anterior shoulder dislocation, even in the primary setting and in the absence of significant glenoid cup bone loss. Retrospective analysis of soft tissue repair in comparison to open coracoid (Latarjet) procedure found at 10-year follow up, redislocation rates were 13% (36) of 271 shoulders with a Bankart repair and 1% (1) of the 93 shoulders with a Latarjet repair. Need for a Pilot Study Prior to a Large Trial: No comparative randomized control trial has been completed evaluating Bankart repair in comparison to Latarjet procedure in the setting of mild to moderate bone loss. Thus, surgeons face uncertainty regarding which procedure to perform. The Latarjet is more invasive (larger incision) and some research suggests it may be more effective at treating instability. The Bankart procedure, while minimally invasive (smaller incision), may result in higher rates of instability after surgery. Study Aims and Objectives: The primary objective of the study is to evaluate the functional shoulder recovery of patients with recurrent shoulder dislocations at 24 months when treated with either arthroscopic capsuloligamentous repair (Bankart Procedure +/- Remplissage) or coracoid transfer (Latarjet procedure). Our trial will compare arthroscopic capsuloligamentous repair vs. coracoid transfer (Latarjet procedure) on: 1. Rates of recurrent shoulder dislocations and symptoms of instability up to 24 months' post- surgery; 2. Clinical outcomes measured by American Shoulder and Elbow Society (ASES) score, Shoulder Activity Scale and EQ-5D and Patient Satisfaction Scale; 3. Physical examination: range of motion, strength, stability; 4. Return to previous level of activity; 5. Rate of shoulder-related complications and serious adverse events. Study Design: The investigators propose a multi-center pilot Randomized Clinical Trial of 126 patients across Canada, United States, Chile and Europe to compare the effect of capsuloligamentous repair (Bankart + Remplissage procedure) and coracoid transfer (Latarjet procedure) in patients with post-traumatic recurrent anterior dislocation. Eligible and consenting participants will be followed-up by the site for 24 months. Outcomes will be assessed at 2 weeks, 3 months, 6 months, 12 months, and 24 months post-surgery. Eligible participants will be randomized to one of two treatment groups: Arthroscopic capsuloligamentous repair (Bankart + Remplissage Procedure) Open or Arthroscopic coracoid transfer (Latarjet Procedure) Once participants have provided informed consent, baseline demographics, relevant medical history, and details regarding their diagnosis will be collected from the participant, the attending surgeon, their medical record and through physical examination. Participants will also complete The Western Ontario Shoulder Instability Index (WOSI) and he American Shoulder and Elbow Surgeons questionnaire (ASES) at the time of enrolment. After surgery, surgical and peri-operative details will be collected from the attending surgeon and the participant's medical records. Adverse events occurring during the surgical procedure or perioperative period will also be documented. ;
