To analyze the functional outcomes after arthroscopic treatment of femoroacetabular impingement (FAI).
194 patients (131 males and 63 females), with a mean age of 39 (15-68) years old for men and 43 (16-58) years old for women. The average follow-up was 17 months (2 to 71). 103 patients presented Cam-type FAI, 102 mixed and 25 Pincer. "Unilateral" arthroscopy was performed in 161 cases, "Bilateral" (only once each side) in 46 cases and, "Multiple" (more than one procedure on the same hip) in 23. The female sex was prevalent in the Pincer type FAI (76%), while males were prevalent in Mixed and Cam type, 74.5% and 72.8%, respectively.
The mean HHSpre score was 63.7 and 87.1 for HHSpost, i.e. 73.11%. Differences appeared between "mixed" and "unilateral" groups. The complications percentage in this series was 18.7% and 7% progressed to total hip arthroplasty.
The arthroscopic FAI treatment improved the postoperative clinical scores of these patients, especially in cases of mixed-type FAI, which presented a higher improvement rate. Insufficient femoral osteoplasty was the main cause for surgical re-intervention, particularly in the initial cases of this series.
分析关节镜治疗股骨髋臼撞击症（FAI）后的功能结果。
194例患者（男性131例，女性63例），男性平均年龄39岁（15 - 68岁），女性平均年龄43岁（16 - 58岁）。平均随访17个月（2至71个月）。103例为凸轮型FAI，102例为混合型，25例为钳夹型。161例行“单侧”关节镜检查，46例行“双侧”（每侧仅一次），23例行“多次”（同一髋关节进行不止一次手术）。钳夹型FAI中女性居多（76%），而混合型和凸轮型中男性居多，分别为74.5%和72.8%。
术前Harris髋关节评分（HHSpre）平均为63.7分，术后（HHSpost）为87.1分，即改善率为73.11%。“混合型”和“单侧型”组之间存在差异。本系列并发症发生率为18.7%，其中7%进展为全髋关节置换术。
关节镜下FAI治疗改善了这些患者的术后临床评分，尤其是混合型FAI患者，其改善率更高。股骨截骨不足是手术再次干预的主要原因，特别是在本系列的初始病例中。
