Arthroscopic Management of the Torn Labrum: From Debridement to Reconstruction
摘要
The labrum is a fibrocartilaginous structure that improves hip joint stability by deepening the socket and creates a fluid seal. It increases joint congruity and reduces contact pressure. Labral tears occur most commonly in the setting of femoroacetabular impingement or hip dysplasia, and labral repair can be a very effective treatment leading to improvements in pain, function and return to activity. However, under certain circumstances, where repair is not possible, debridement can be performed, which is associated with good outcomes. In other circumstances where repair may not be appropriate or has already failed, reconstruction may need to be considered to restore the integrity of the chondrolabral junction. A variety of different methods of reconstruction using autograft and allograft have been reported previously and are discussed. Labral reconstruction is a technically difficult procedure requiring advanced expertise in arthroscopic surgery; however, it is associated with a low complication rate, especially when performed by experienced surgeons. The author reports on his experience and describes his technique of labral reconstruction using a fascia lata allograft.
