15 years of dance to blame: dysplasia leading to early osteoarthritis is even more likely in dancers. "[S]hallow sockets allow for a big range of motion, so dancers are a self-selected group in which to find this problem. It is easy to imagine how dancers also overload the hip: The continual external rotation demanded by the turn-out position of the legs further stresses the malformed weightbearing surfaces. Repetitive jumping increases the impact injury and over time accelerates the deterioration of the joint cartilage...there may be stretching or tearing of the ligaments over the joint, the breakdown or "tearing" of the acetabular labrum... Once the deterioration of cartilage is set in motion, there can be very rapid worsening of the hip integrity leading to osteoarthritis, even within a few months." dancerhips/pao.html
