摘要目的:通过Meta分析比较髋关节镜手术中关节囊缝合与未缝合治疗髋关节撞击综合征（FAI）的效果。方法:在Cochrane Library、PubMed、Web of Science、中国知网、万方数据库等中、英文数据库中检索关于髋关节镜术中关节囊缝合与未缝合治疗FAI的疗效比较的随机对照研究（RCT），检索时间为各数据库建库至2024年10月。采用RevMan 5.3软件通过Meta分析比较髋关节镜手术中关节囊缝合与未缝合患者在术后2年内改良髋关节Harris评分(mHHS)、12项国际髋关节成果工具功能评分（iHOT-12）、髋关节结局评分日常生活能力量表(HOS-ADL)评分、髋关节结局评分运动量表（HOS-SSS）评分、哥本哈根髋关节和腹股沟疗效量表（HAGOS）评分、疼痛视觉模拟（VAS）评分、再手术率、并发症发生率及患者满意率方面的差异。结果:共纳入5篇RCT，合计432例患者，其中关节囊缝合组215例，未缝合组217例。文献中患者随访时间为12~24个月。Meta分析结果显示，关节囊缝合组与未缝合组患者在术后mHHS评分、iHOT-12评分、HOS-SSS评分、HAGOS评分、VAS评分、再手术率、并发症发生率及患者满意率方面差异均无统计学意义（ P>0.05）。关节囊缝合组患者术后2年HOS-ADL评分显著优于未缝合组（MD=-3.57，95% CI：-5.86~-1.28， P=0.002）。 结论:关节囊缝合可显著改善FAI患者髋关节镜术后中期生活能力，但在短期髋功能、疼痛控制、再手术率及并发症发生率方面与关节囊未缝合相近。

abstractsObjective:To compare the clinical outcomes of capsular closure versus those of non-closure in hip arthroscopy for femoroacetabular impingement (FAI) through a meta-analysis of randomized controlled trials (RCTs).Methods:A systematic search was conducted in Cochrane Library, PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Database for RCTs comparing capsular closure with non-closure in hip arthroscopy for FAI, covering the period from database inception to October 2024. A meta-analysis was performed using RevMan 5.3 software to compare outcomes between patients undergoing hip arthroscopy with capsular closure versus those without capsular closure within 2 years postoperatively. The following parameters were evaluated: the modified Harris hip score (mHHS), 12-item International Hip Outcome Tool (iHOT-12), hip outcome score-activities of daily living (HOS-ADL), hip outcome score-sport specific (HOS-SSS), Copenhagen hip and groin outcome score (HAGOS), visual analog scale (VAS) for pain, reoperation rate, complication rate, and rate of patient satisfaction.Results:A total of 5 RCTs involving 432 patients were included, with 215 cases in the capsular closure group and 217 cases in the non-closure group. The follow-up duration for the patients in the included studies ranged from 12 to 24 months. Meta-analysis revealed no significant differences between the capsular closure and non-closure groups in postoperative functional scores (mHHS, iHOT-12, HOS-SSS, HAGOS), VAS pain score, reoperation rate, complication rate, or rate of patient satisfaction ( P>0.05). The capsular closure group demonstrated significantly better HOS-ADL at 2 years postoperatively than the non-closure group (MD=-3.57, 95% CI: -5.86 to -1.28, P=0.002). Conclusion:In patients with FAI undergoing hip arthroscopy, compared to the non-closure, capsular closure leads to significant improvements in mid-term daily activities, but similar outcomes in short-term hip function, pain control, reoperation rate, and complication incidence.
