摘　　要：目的 借助磁共振成像(MRI)对关节软骨的显影优势,探讨半月板撕裂术后软骨损伤的相关危险性因素。方法 回顾性分析上海市第六人民医院膝关节半月板关节镜手术患者的临床及影像资料,术前患者均有半月板的撕裂,无明显软骨损伤影像表现。以膝关节术后3年内MRI表现有无软骨损伤分为两组:软骨损伤组和无软骨损伤组,分别评价患者年龄性别、BMI指数、手术方式、手术部位、半月板半脱位情况、术前半月板撕裂类型、撕裂范围、术后时间的差异,采用卡方检验统计差异的统计学规律,利用Logistic回归分析各因素与术后软骨损伤的相关性。结果 入组的半月板术后患者为88例。术后发生软骨损伤共43例,无软骨损伤共45例。两组资料在性别(P=0.010)、手术方式(P<0.001)、手术部位(P=0.026)及BMI指数(P=0.047)均具有统计学差异。进一步Logistic回归分析发现,手术方式(P<0.001)、BMI指数(P=0.047)均与软骨损伤相关。结论 软骨损伤作为关节镜术后的常见并发症,其发生与患者的性别、手术部位、手术方式、BMI指数显著相关,其中手术方式是发生术后软骨损伤的重要危险因素。Objective To study on the relative risk factors of cartilage injury after the surgery of meniscus tear with the help of the advantages of Magnetic Resonance Imaging(MRI) on the development of articular cartilage. Methods A retrospective analysis of the clinical and imaging data of patients undergoing arthroscopic surgery of the knee joint meniscus in Shanghai Sixth People’s Hospital was carried out. All the patients were diagnosed as meniscus tears by MRI and no obvious cartilage damage was found before surgery. They were divided into two groups based on the MRI findings of the knee joint within 3 years after surgery: the cartilage injury group and no cartilage injury group. Age, gender, BMI index, surgical method, surgical site, meniscus subluxation, preoperative meniscus tear type, tear range, postoperative time were collected and analyzed by chi-square test. Logistic regression was applied to analyze the correlation between various factors and postoperative cartilage damage. Results A total of 88 patients were enrolled, 43 cases had cartilage injury after operation while 45 cases had no cartilage injury. There were significant differences on gender(P=0.010), surgical method(P<0.001), surgical site(P=0.026) and BMI index(P=0.047) between two groups. Further logistic regression analysis found that surgical methods(P<0.001) and BMI index(P=0.047) were all bound up with the cartilage damage. Conclusion The occurrence of cartilage injury was significantly bound up with the patient’s gender, surgical site, surgical method, and BMI index. The surgical method might be an important risk factor in postoperative cartilage injury.
