Hip pain can be due to a number of causes. This can range from simple tendonitis from overuse to osteoarthritis, which is a wearing down of the cartilage in the hip joint (typically seen in patients over the age of 50). In between this spectrum of causes however is a condition called femoroacetabular impingement or FAI. This problem is typically seen in younger, athletic people such as those involved in football, soccer, or basketball, but is not uncommonly seen in dancers, gymnasts, and other sports that require increased flexibility. Although it is seen in these athletes, due to its cause it can also be seen in individuals who are not involved in competitive sports as well.
