see also Hip Impingement
The labrum is a semilunar (crescent-shaped) cartilage structure that runs along the rim of the hip socket that provides an added cushion and stability to the hip joint. Labral tears can be caused by a sudden, specific injury or with repetitive motions that cause "wear and tear." Patients have pain deep in the groin on the side of the involved hip. This may be accompanied by a clicking or locking sensation in the hip.
For those with persistent pain from labral tears, there are many treatment options, including physical therapy and anti-inflammatory medications. When pain from a labral tear proves resistant to non-operative treatment, arthroscopic surgery is frequently indicated.
