BIO-RSA vs standard reverse shoulder replacement study
Part of Bones, joints & muscles clinical trials.
This study compares two types of reverse shoulder replacement: one that uses a bone graft (BIO-RSA) and one that doesn't. It aims to see if the BIO-RSA method gives better pain relief and function for people with arthritis, large rotator cuff tears, or failed prior cuff surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled to have a first-time reverse shoulder replacement for osteoarthritis, a large rotator cuff tear, a failed rotator cuff repair, or arthritis after shoulder instability.
- You can read and write Norwegian.
- You do not have severe osteoporosis (very weak bones).
- You do not have osteonecrosis of the humeral head (dead bone in the upper arm).
- You do not have dementia, poor deltoid muscle function, or need revision surgery.
- You are not ASA class IV, have no suspected chronic infection, and this is not for an acute fracture.

This study compares two types of reverse shoulder replacements: one that uses a small piece of your own bone (BIO-RSA) and another that uses a special metal implant (MIO-RSA) to fill the socket. The goal is to see which one stays more stable in the bone after surgery.
This trial studies a rehabilitation plan after reverse total shoulder arthroplasty (reverse shoulder replacement) to see if it improves recovery. If you are eligible, you may be guided through specific therapy and follow-up visits as part of the study.
This trial looks at a specific shoulder replacement implant and follow-up care for people who need a shoulder arthroplasty (shoulder replacement) for certain joint problems or fractures. You may be a candidate if you can take part in required visits and your shoulder muscles and bone are suitable.
This study tests if a special exercise program before shoulder replacement surgery improves how well you can rotate your arm inward after the operation. Participants do exercises for 6 weeks before surgery and are followed for 2 years.
This study compares two types of shoulder replacement surgery for people with severe shoulder arthritis and a torn rotator cuff. It aims to see if one approach provides better muscle function and outcomes.
This trial compares two ways of doing shoulder arthroplasty (shoulder replacement) for people with advanced shoulder arthritis who have not improved with non-surgical treatments. It may help determine which approach works better for pain and function.
