Multifactorial approach training for anterior shoulder instability after a Latarjet procedure: protocol for a randomised controlled trial.

INTRODUCTION: The Latarjet procedure is the mainstay treatment in high-demand patients with substantial glenoid bone loss or after failed capsulolabral repairs. Patients typically return to sport (RTS) within 6 months postoperatively, requiring intensive rehabilitation. Current rehabilitation protocols focus on mobility, strength and stability. Yet, psychological factors, such as fear of reinjury, are the main reason not to RTS. Therefore, this study aims to determine whether integrating psychological interventions into postoperative rehabilitation improves patient-reported shoulder function compared with physical therapy alone. METHODS AND ANALYSIS: This monocentric randomised controlled trial will enrol 52 patients undergoing a Latarjet procedure for anterior shoulder instability. Participants will be equally and randomly assigned to either postoperative physical therapy combined with cognitive behavioural therapy or physical therapy alone. Eligibility criteria include patients aged 18-67 years undergoing an open or arthroscopic Latarjet procedure at our institution. Exclusion criteria include posterior or multidirectional instability, rotator cuff tear, prior shoulder surgery, anxiety disorder, using anxiolytics, neurological disorder, systemic disease, previous hospitalisation for shoulder pain and proximal humerus fractures.The primary outcome is the Western Ontario Shoulder Index at 6 months postoperatively. Secondary outcomes include incidence of recurrent dislocations, RTS and return-to-work rates, Tampa Scale of Kinesiophobia for Shoulder Instability, subjective shoulder value and visual analogue score for pain at 6 months postoperatively as well as the Shoulder Instability Return to Sport after Injury scale at 4.5 months postoperatively.
