Summary

This trial tests whether open surgical reconstruction of a torn hip abductor tendon reduces pain better than a sham (placebo) surgery. Adults with MRI-confirmed tendon tears and lateral hip pain for over a year are randomly assigned to receive either real surgery or a sham procedure. The main outcome is patient-reported pain at six months using the HAGOS pain score.

What this could mean

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

Active substance
open surgical reconstruction of hip abductor tendon with bone anchors
What this could lead to
If surgery proves better than sham, it could become a standard treatment for chronic hip tendon tears that don't heal on their own.
What could go wrong
This is a relatively small, early-stage trial. Surgery may not outperform sham, and carries risks like infection, nerve damage, or prolonged recovery.
