Reverse or Anatomical replacement for Painful Shoulder Osteoarthritis, Differences between Interventions (RAPSODI-UK)

To find the best type of joint replacement for the treatment of painful osteoarthritis of the shoulder in adults aged 60 years or older.

The research will be undertaken in NHS shoulder arthroplasty units in England, Wales and Northern Ireland. Patients will be screened for eligibility (suitable for shoulder arthroplasty and intact rotator cuff) and invited for recruitment prior to surgery. Patients will be randomised prior to surgery and will be blinded to which type of replacement they received. We will recruit 430 patients and follow their recovery and outcomes periodically over the course of 24 months. We will also conduct a nested qualitative study of 20 participants who will be interviewed at 2 and 12 months after surgery.
