Femoroacetabular impingement—otherwise known as hip impingement—affects approximately one-third of the population. Because it is often asymptomatic in the early stages, it tends to go undiagnosed for many years. More common in young athletes, hip impingement is also associated with osteoarthritis; that is, individuals with the condition have a greater risk of developing arthritis over time. While there is currently no cure, appropriate treatment can effectively manage the symptoms of femoroacetabular impingement.
In people with femoroacetabular impingement, the femoral head of the hip does not have a full range of motion (often because there is too much bone around the head) within the acetabular socket. Over time, frequent rubbing can injure the labral or articular cartilage. As degeneration progresses, there is an increased risk of osteoarthritis.
