Summary

This study looked at whether repairing the subscapularis tendon during reverse shoulder replacement surgery leads to better short-term outcomes. A total of 102 adults having primary reverse shoulder arthroplasty took part. Half had the tendon repaired, half did not. The goal was to see if the repair made a difference in how patients felt and functioned after surgery.

What this could mean

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

Active substance
subscapularis tendon repair (surgical procedure)
What this could lead to
If repairing the tendon proves beneficial, it could become a standard part of reverse shoulder replacement to improve recovery.
What could go wrong
This is a small, completed trial focused only on short-term outcomes. The results may not apply to all patients or show long-term benefits.
