Femoroacetabular Impingement

Our Pediatric Sports Medicine team put together these videos to provide information for you.

What is Femoroacetabular Impingement (FAI)?

The hip is a ball and socket joint. The ball is the femoral head and the socket is formed by the acetabulum. The acetabulum is ringed by a strong fibrocartilage called the labrum.

Femoroacetabular impingement is a condition where the bones of the hip are abnormally shaped. Because they do not fit together perfectly, the hip bones can hit or impinge against each other during hip flexion and cause damage to the hip. Over time, this can result in the tearing of the labrum and degeneration of the joint socket. 

How do I know if I have FAI?

People with Femoroacetabular impingement usually have pain in the groin area. Stabbing or achy pain usually occurs with deep hip flexion and squatting activities. Because athletically active people may work the hip joint more vigorously, they may begin to experience pain earlier than those who are less active.

How is FAI diagnosed?

The Johns Hopkins All Children's Sports Medicine team, will examine your hip with specific tests to help diagnose femoroacetabular impingement. X-rays and Magnetic resonance imaging may be needed to help identify this condition. Injecting dye into the joint during the MRI may make damage show up more clearly. 

What are my treatment options?

Femoroacetabular impingement can sometimes be initially treated with anti-inflammatory medication and avoiding activities that cause symptoms. If symptoms are not relieved with conservative measures, arthroscopic surgery may be needed. Using cutting edge techniques, we can place a small camera into the hip joint. Damage to the labrum can be repaired, and any deformity can be reshaped to prevent impingement. 
Correcting the impingement lesion can reduce symptoms and prevent future damage to the hip joint. 

Care after surgery? 

Return to activity can be expected 4-6 months after surgery.
