The damage to the cartilage inside the socket of the hip joint makes your thighbone less stable inside the joint. The damage can also allow the fluid that keeps the cartilage smooth to more easily escape from the joint. This can cause friction in your hip.
Labral tears more commonly occur in the front and top portions of the labrum.
Causes and Risk Factors
Acetabular labral tears often occur with other injuries or conditions in the hip. For example, hip fractures can tear your labrum. Most patients with osteoarthritic hips also have labral tears. Patients with acetabular dysplasia (an abnormality during development that results in a misshapen hip socket) often develop labral tears and osteoarthritis of the hip.
Contact sports increase your chances of re-injuring your hip. Sports that require you to bend forward, like skiing, cycling or horseback riding also may put you at risk of re-injuring your acetabular labrum. If you are going to engage in physical activity, particularly sports that involve running, jumping and twisting be sure to stretch the muscles in your hips and lower back well first.
