摘　　要：目的调查分析膝关节软骨损伤的临床流行病学特征。方法收集2005年10月至2009年12月本中心2 479例膝关节镜手术患者视频及病历资料,分析不同程度关节软骨损伤的病例构成比、性别比、平均年龄与分布、发生部位与数量及常见与高发疾病的分布。结果关节软骨损伤者占55.1%,与无软骨损伤者比较,性别构成差异无统计学意义（P〉0.05）,年龄（41.31±15.88）岁,30~59岁为高发年龄段;右膝多于左膝（P〈0.05）,好发部位为股骨滑车、胫骨外侧平台、髌骨;其常见疾病为半月板损伤、交叉韧带损伤、原发性OA,高发疾病为关节结核、类风湿性关节炎、关节僵直和粘连、髌骨轨迹异常。关节软骨损伤病例中Ⅰ~Ⅳ级者分别占27.45%、29.94%、14.71%、27.89%,各级别损伤者的性别比、平均年龄与分布、损伤部位与数量均存在统计学差异（P〈0.05）。结论膝关节软骨损伤十分常见,患者年龄分布范围大,中青年为主要人群,性别构成比相近。不同程度、不同疾病关节软骨损伤病例性别构成比不同,不同程度软骨损伤病例年龄分布特征不同。Objective To identify the clinical epidemiological features of articular cartilage lesions of knee.Methods The data of 2 479 cases（2 556 knees） concerning surgery video and medical records of total knee arthroscopy from October 2005 to December 2009 were retrieved from the database of our center.The prevalence,importance population information,age and location distribution,common illnesses and frequently encountered diseases were analyzed retrospectively in these difference stage cases of articular cartilage lesions.Results In the total cases the prevalence of articular cartilage lesions accounted for 55.1%.There was no significant difference in gender ratio between those with articular cartilage lesions and those without.The average age of articular cartilage lesions was 41.31±15.88,and the most common age bracket ranged from 30 to 59 years old.More was found in the right knee than in the left（P0.05）.The predilection locations of articular cartilage lesions were the femoral trochlea,lateral tibia platform and patella.The common illnesses included meniscus injury,cruciate ligament tear and primary osteoarthritis.The highly frequent diseases were tuberculosis of joint,rheumatoid arthritis,joint adhesions and stiffness,patellofemoral joint abnormality and meniscus injury.The prevalence of articular cartilage lesions in different stages was 27.45% for grade Ⅰ,29.94% for grade Ⅱ,14.71% for grade Ⅲ and 27.89% for grade Ⅳ.There were significant differences in gender ratio,mean age and age bracket,and predilection locations and numbers among the articular cartilage lesions in different stages（P0.05）.Conclusion Clinically,articular cartilage lesions are common in the knee joint.The range of age distribution is wide.Young people are major population,and no gender difference is seen.Gender constituent ratio is different for the cartilage lesions at different severity and for different lesions,and age distribution is different for the lesions at different severity.
