What this trial studies

This trial investigates the effectiveness of reverse shoulder arthroplasty (RSA) compared to a 12-week physiotherapist-supervised exercise program in patients with rotator cuff arthropathy. Participants eligible for RSA will be randomly assigned to either receive the surgical intervention followed by standard rehabilitation or to engage solely in the exercise program. The primary outcome will be assessed using the Western Ontario Osteoarthritis of the Shoulder index score at 12 months, with follow-ups at various intervals. The study aims to determine if surgical treatment leads to significantly better outcomes than non-surgical exercise therapy.

Who should consider this trial

Good fit: Ideal candidates are patients aged 60-85 years with rotator cuff arthropathy eligible for reverse shoulder arthroplasty.

Not a fit: Patients with previous shoulder fractures, other types of arthritis, or neurological diseases affecting shoulder mobility may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence for the most effective treatment approach for patients with rotator cuff arthropathy, potentially improving pain management and functional outcomes.

How similar studies have performed: Previous studies have suggested the need for trials comparing surgical and non-surgical treatments for shoulder conditions, indicating that this approach is novel and underexplored.
