Hip Impingement / FAI

What is FAI?

Femoroacetabular impingement (FAI) of the hip is a condition in which there is a mismatch in shape between your femoral head and neck (ball) and acetabulum (socket). Because they do not fit together perfectly, the bones hit against each other during movements such as squatting. Over time, this friction can damage the labrum and cartilage of the joint, causing pain and limiting activity.

FAI can cause groin pain that is worse with sitting and squatting. Diagnosis of FAI is made by knowing your symptoms, medical history, performing a physical examination of the hip, and performing other diagnostic tests such as X-rays, MRI, and CT scans.
