Summary

This study compares surgery to physical therapy for people who have dislocated their kneecap for the first time. Researchers want to see which approach better prevents repeat dislocations and improves knee function. The trial will follow 200 participants for up to 10 years.

What this could mean

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

Active substance
medial patellofemoral ligament reconstruction surgery
What this could lead to
If successful, this trial could show that surgery is better than physical therapy at preventing future kneecap dislocations and improving long-term knee function.
What could go wrong
This trial has not yet started recruiting, and results may take years. Surgery carries risks like infection or stiffness, and physical therapy may not work for everyone.
