Study Details

Brief summary:

The goal of this clinical trial is to learn if the hips of people who undergo revision hip arthroscopy look different from the hips of people whose hip pain is resolved with the first hip arthroscopy and of people who choose the steroid injection for pain management.

Participants will complete one PET/MRI scan.
