METHODS: Fifty hip arthroscopies performed in 45 patients were retrospectively evaluated. Exclusion criteria were: age > 40, hip arthritis > grade 2 according to Tonnis classification, femoral head avascular necrosis, pediatric\'s orthopaedics conditions and true dysplasia with LCEA < 18°.Two groups were identified: group A with 15 hips with LCEA between 25° and 18° and Group control B made of 35 hips with LCEA > 25°.
RESULTS: The groups were homogeneous for demography and pre-operative WOMAC and HOOS. Osteoplasty for CAM were performed in 100% of patients in both groups, only in 12 hips (34.4%) in group B we had both femoral and acetabular osteoplasty. Labral repair was performed in 86% of patients in group A, in 60% of patients in group B, capsular plication in 93% of group A, in 5% of case of group B. WOMAC and HOOS statically significant improved in both groups at final follow-up (24 months). No cases in both groups required conversion to total hip arthroplasty. Clinical outcomes of study group were comparable to the control group.
CONCLUSIONS: Even if the present small series is not conclusive, we suggest isolated arthroscopic management of patients with FAI and LCEA between 18° and 25°, but capsular plication and careful labral management are strongly recommended.
METHODS: Level IV.
方法:对45例患者进行了50次髋关节镜检查。排除标准为:年龄>40岁,根据Tonnis分类,髋关节炎>2级,股骨头缺血性坏死,儿童的骨科条件和真正的发育不良与LCEA<18°。确定了两组:A组15髋,LCEA在25°至18°之间,对照组B由35髋,LCEA>25°。
结果:各组在人口统计学和术前WOMAC和HOOS方面是同质的。两组中100%的患者都进行了CAM的骨成形术,B组仅在12髋(34.4%)中进行了股骨和髋臼骨成形术。A组86%的患者进行了Labral修复,B组60%的患者,A组93%的包膜折叠,在B组5%的病例中,WOMAC和HOOS在最终随访(24个月)时两组均有统计学意义的改善。两组均无一例需要转换为全髋关节置换术。研究组的临床结果与对照组相当。
结论:即使目前的小系列没有定论,我们建议对FAI和LCEA在18°和25°之间的患者进行单独的关节镜治疗,但强烈建议进行囊袋折叠和仔细管理。
方法:四级。
