Summary

This study compares two versions of a shoulder replacement surgery for people with shoulder arthritis. In one version, surgeons repair a small but important tendon called the subscapularis; in the other, they leave it unrepaired. The goal is to see which approach gives better shoulder function and less pain over two years. About 284 participants will be randomly assigned to one of the two procedures.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
reverse total shoulder arthroplasty (a type of shoulder replacement surgery) with or without repair of the subscapularis tendon
What this could lead to
If successful, this could show that repairing the subscapularis tendon during shoulder replacement leads to better shoulder function and less pain for patients with arthritis.
What could go wrong
This is a relatively small, early-stage trial, and results may not apply to all patients. Surgery always carries risks like infection, nerve damage, or implant failure.
