Randomized controlled trial of hip arthroscopy for femoroacetabular impingement

髋臼撞击(FAI)是骨盆与股骨头颈交界处的异常接触导致髋关节损伤的结果。由于FAI与症状相关，并可能在骨关节炎的易感性中发挥作用，因此已经开发了新的外科技术来纠正这种解剖异常。然而，手术改善疾病的益处尚不清楚。因此，我们提出了一项随机对照试验来评估其疗效并确定其作用机制。

Femoroacetabular impingement (FAI) occurs as a consequence of abnormal contact between the pelvis and femoral head–neck junction, resulting in damage to the hip joint. Because FAI is associated with symptoms and may play a role in predisposing to osteoarthritis, new surgical techniques have been developed to correct this anatomic abnormality. However, the disease modifying benefits of surgery are unknown. We therefore propose a randomized controlled trial to evaluate its efficacy and to determine the mechanisms of effect.
