Acetabular Labrum Tears
The acetabular labrum is the cartilage that coats the rim of the acetabulum (hip socket) and acts to make the hip socket deeper and more stable. A tear to the acetabular labrum typically occurs due to trauma, either a significant single trauma or repetitive micro-trauma, but is associated with a number of risk factors including femoroacetabular impingement, capsular laxity or hip dysplasia. Acetabular labrum tears may cause further chondral (cartilage) damage and/or early degenerative changes. Acetabular labrum tears typically present with moderate to severe pain, predominantly in the groin, that is present at night and is aggravated by activity. They may also cause a limp or an occasional ‘giving-way’ of the hip.
