Proponents of femoroacetabular impingement (FAI) now claim that FAI is an important risk factor for hip osteoarthritis and argue that early, aggressive treatment is indicated to stave off long-term complications. The result is more young patients undergoing corrective surgery; does the literature support these claims or has hype trumped reality? This article critically reviews these assertions together with the current scientific evidence that defends (or refutes) them.
Each reader will need to weigh the evidence carefully when interpreting images or planning management for patients with possible FAI.
股骨髋臼撞击症（FAI）的支持者现在声称 FAI 是髋关节骨关节炎的一个重要危险因素，并认为早期积极治疗是预防长期并发症的关键。其结果是更多的年轻患者接受了矫形手术；文献是否支持这些说法，还是炒作超过了现实？本文批判性地回顾了这些观点，并结合了支持（或反驳）这些观点的当前科学证据。
每个读者在解读可能有 FAI 的患者的影像或制定治疗计划时，都需要仔细权衡证据。
