HIP IMPINGEMENT (FEMORO-ACETABULAR IMPINGEMENT)
The damage can occur to the articular cartilage (smooth surface of the ball or socket) or the labral cartilage (soft tissue bumper of the socket). FAI is a leading cause for the development of osteoarthritis, particularly in men.
The excess bone around the hip leads to friction and labral damage. Once the labrum has been injured, the hip joint surface (articular cartilage) becomes exposed and damaged due to on-going friction. This can lead to arthritis.
WHAT CAUSES HIP IMPINGEMENT?
WHY DOES IT BECOME PAINFUL?
WHAT IS THE NATURAL COURSE OF HIP IMPINGEMENT?
Over time, FAI causes progressive damage to the cartilage on the rim of the hip socket, leading to osteoarthritis. While osteoarthritis develops over a long time, surgical treatment of the abnormality causing FAI may slow or prevent the progression of joint damage and improve symptoms.
WHAT TREATMENT IS AVAILABLE?
WHAT IS HIP ARTHROSCOPY?
At arthroscopy the cause for the impingement is removed (removal of CAM or pincer lesion) and the labrum is repaired. The damaged articular cartilage is also repaired (see ABICUS procedure).
