This occurs when the hip ball and socket joint are not equally matched leading to problems with certain movements and impingement caused by friction from the two surfaces. The impingement can pinch soft tissues around the hip leading to a labral tear and over time, can damage the surface joint leading to wear and tear. Symptoms include pain particularly when twisting, bending or crouching. Clicking is sometimes noticed and can also be painful. Activity modification can reduce symptoms. Pain killers or anti-inflammatory tables or injections can be helpful for symptom relief. Hip arthroscopy can be considered to repair torn labrum as well as removing bony areas causing friction.
