Biologics in hip preservation
The identification and understanding of non-arthritic hip conditions has grown rapidly in the last two decades. New pathologies have been described including femoroacetabular impingement, hip microinstability, deep gluteal syndrome and greater trochanteric pain syndrome. Even though the treatment of these disorders has yielded good clinical results, there is always a desire to improve outcomes and the speed in which they are attained. Biologic therapies have emerged as a new or adjunctive modality to improve clinical outcomes of hip pathology, as well as, a potential way to accelerate healing times and return to play. This review focuses on the use of current biologic therapies, specifically platelet-rich plasma, hyaluronic acid and stem cells, in the treatment of various hip pathologies.
