PURPOSE The purposes of this study were to (1) evaluate the effect of age on clinical outcomes of arthroscopic femoroacetabular impingement (FAI) with labral preservation surgery and (2) identify predictors of poor postoperative clinical outcomes. METHODS Eighty-four patients who underwent hip arthroscopic treatment for FAI between 2009 and 2013 were retrospectively reviewed. Patients were divided into three groups based on age. The Advanced age group consisted of patients over 70 years old, the Middle age group consisted of patients in their 50s and 60s, and the Younger age group consisted of patients less than 50 years of age. Total hip arthroplasty (THA) conversion, radiographic progression of osteoarthritis and patient-reported outcomes including modified Harris Hip Score (MHHS) and Non-arthritic Hip Score (NAHS) were investigated. RESULTS The mean follow-up period was 32.2 (range 24-60) months. THA was required in 3 patients in their 50s and 60s, which was a significantly higher rate compared to that in patients Younger than 50 years old (17% vs 0%, p = 0.036). Progression to osteoarthritis was also significantly more frequent in patients in their 50s and 60s than in patients in their 70s (50s and 60s: 33%; 70s: 0%, p = 0.030). In all age groups, the preoperative MHHS and NAHS improved at last follow-up (p < 0.001). The 50s and 60s age group [hazard ratio (HR) 6.62], preoperative mild osteoarthritic change (Tönnis grade 1, HR: 3.29) and severe cartilage damage on the acetabulum (HR: 2.63) were risk factors for progressive osteoarthritis and THA conversion. CONCLUSIONS Arthroscopic FAI correction and labral preservation surgery provide favourable clinical outcomes for patients over 70 years old in the absence of significant osteoarthritis and severe acetabular chondral damage. Patients in their 50s and 60s have a higher risk of both THA conversion and progressive osteoarthritis, while patients aged over 70 years show no evidence of progressive osteoarthritis. Chronologic age in isolation is not an absolute contra-indication to hip arthroscopy. LEVEL OF EVIDENCE III.

关节镜检查股骨髋臼撞击矫正术和保留唇部手术后，年龄在70岁以上的患者没有进行性骨关节炎的高风险。

目的这项研究的目的是（1）评估年龄对人工唇保留手术的关节镜下股髋臼撞击（FAI）的临床效果的影响，以及（2）识别术后临床效果差的预测因素。方法回顾性分析2009年至2013年接受髋关节镜下FAI治疗的84例患者。根据年龄将患者分为三组。高龄组由70岁以上的患者组成，中龄组由50多岁和60多岁的患者组成，而低龄组由少于50岁的患者组成。研究了总髋关节置换术（THA）的转换，骨关节炎的影像学进展以及患者报告的结局，包括改良的Harris髋关节评分（MHHS）和非关节炎髋关节评分（NAHS）。结果平均随访时间为32.2（24-60）个月。3例分别在50年代和60年代的患者需要THA，这与50岁以下的患者相比显着更高（17％vs 0％，p = 0.036）。在50多岁和60多岁的患者中，进展为骨关节炎的比例也明显高于70多岁的患者（50多岁和60多岁的比例为33％； 70多岁的比例为0％，p = 0.030）。在所有年龄组中，术前MHHS和NAHS在最后一次随访时均改善（p <0.001）。50岁和60岁年龄段[危险比（HR）6.62]，术前轻度骨关节炎改变（Tönnis1级，HR：3.29）和髋臼严重软骨损伤（HR：2.63）是进行性骨关节炎和THA转换的危险因素。结论关节镜FAI矫正和阴唇保留手术为70岁以上无明显骨关节炎和严重髋臼软骨损伤的患者提供了良好的临床效果。50多岁和60多岁的患者发生THA转化和进行性骨关节炎的风险较高，而70岁以上的患者则没有进行性骨关节炎的证据。孤立的年代学年龄并不是髋关节镜检查的绝对禁忌症。证据级别III。孤立的年代学年龄并不是髋关节镜检查的绝对禁忌症。证据级别III。孤立的年代学年龄并不是髋关节镜检查的绝对禁忌症。证据级别III。
