Labrum tears of the hip can result from a variety of causes, including hip impingement (most common), hip dysplasia, hip instability, prior growth plate injury, or trauma.  It is important to note that labrum tears always have a cause, and they do not occur in a normal hip without trauma – thus, the labrum is the smoke, while hip impingement, dysplasia etc. is the fire.  When surgery is indicated to fix labral tears, this can be done effectively using arthroscopic techniques.  After entering the joint, the labrum is examined, the tear location determined, and the bony rim is prepared for insertion of a suture anchor.  A specialized anchor attached to a strong, non-dissolving suture is inserted into the bone of the hip socket.  The suture is then passed around the labrum using a variety of tools, and then the suture is tied or cinched down, securing the labrum back to the bony rim of the socket, fixing the tear.  The repaired labrum then sits properly on the surface of the ball, which restores normal labrum function and reduces pain.  Rehabilitation from a labral repair typically follows the same outline in the hip arthroscopy section and is modified as needed.
