Tests how hip mechanics change with femoroacetabular impingement
Part of Bones, joints & muscles clinical trials.
This study measures how your hip moves (the “mechanics”) using clinical exams and imaging. It may help researchers understand hip movement problems in femoroacetabular impingement (FAI) before major joint damage develops.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have hip pain and have been diagnosed with femoroacetabular impingement (FAI)
- Your X-ray shows a specific pattern of hip bone shape (cam, pincer, or mixed FAI)
- If you’re a control volunteer: you’re age 18–35 and X-rays do not show hip deformity/FAI or dysplasia
- You must not have advanced arthritis seen on X-ray (Tonnis grade III or IV)
- You must not have had surgery to fix FAI or other hip problems (but minor exploratory procedures may be allowed)
- You must be able to do movement tests and stay still for imaging, and you must meet body size limits (BMI and hip size)

Other trials that look related to this one.
This study compares hip positioning (acetabular angle) with pelvic tilt in people with femoro-acetabular impingement and in healthy volunteers. It may help researchers better understand hip mechanics and how they relate to symptoms and planning for arthroscopy surgery.
This study tests whether rotating the leg during hip arthroscopy improves outcomes for people with femoroacetabular impingement (FAI), a condition where extra bone on the hip causes pain and limited movement. It aims to see if this rotation technique reduces pain and improves function better than standard surgery.
This study tests whether using 3D-printed models from scans can help plan hip preservation surgery for people with a specific hip shape problem (cam-type femoroacetabular impingement). It may help surgeons plan more precisely, though you would only be eligible if your hip damage and other health factors fit specific limits.
This trial tests whether a program of education plus exercise can reduce long-term hip or groin pain. It may help by improving movement and function, especially when pain has lasted more than 3 months.
This trial looks at how a CAM-type hip impingement (a bump on the ball of the hip joint) affects hip movement and stress. It compares men with and without symptoms to understand what causes pain and how to prevent future hip problems.
This study looks at how doctors make decisions about treating hip impingement (FAIS) in young adults. If you join, you'll be part of a study that may help improve care for others with similar hip problems.
