Surgical management techniques for avascular necrosis of the femoral head: a systematic review
Early surgical intervention for avascular necrosis (AVN) of the femoral head can preserve the hip joint and delay the need for total hip arthroplasty (THA). Therefore, the purpose of this study is to compare the efficacy of various surgical modalities to treat femoral head AVN as assessed by THA-free survivorship, radiographic failure, and patient reported outcomes measures (PROMs).
