Rehabilitation Following Reverse Total Shoulder Arthroplasty

This study compares different rehabilitation approaches after reverse total shoulder arthroplasty (rTSA) — a type of shoulder replacement surgery used for patients with severe rotator cuff tears, shoulder arthritis, or fractures. In a reverse shoulder replacement, the ball and socket are 'reversed' compared to normal anatomy, which allows the deltoid muscle (rather than the rotator cuff) to power arm movement. After surgery, patients undergo a rehabilitation program, but the optimal approach and timing are not well established. The study follows patients for at least one year, tracking their shoulder strength, range of motion, pain, and quality of life under different rehabilitation protocols. You may be eligible if: - You are over 55 years old - You are scheduled for a primary reverse total shoulder arthroplasty - You are able to complete questionnaires and attend follow-up visits - You speak and read English proficiently You may NOT be eligible if: - Your surgery is for a proximal humeral fracture (not the typical indication) - You have had previous shoulder surgery - You have active shoulder infection, inflammatory arthropathy, rheumatoid arthritis, or gout - You are an active tobacco user or have smoked within the past 8 weeks - You have uncontrolled diabetes (HbA1C over 7.5%) - You have a life expectancy of less than 2 years or very high surgical risk Talk to your doctor to see if this trial is right for you.
