Clinical Research on Articular Cartilage Injury Complicated with the Rupture of Anterior Cruciate Ligament in Athlete and Non-athlete

目的：通过对21例运动员与43例非运动员膝关节前交叉韧带(ACL)断裂后并发膝关节软骨损伤的观察，分析探讨其损伤继发关节软骨损伤的原因及规律。方法：应用膝关节镜观察关节软骨损伤的部位、病理改变、损伤程度，然后对损伤发生率、发生时间、损伤程度与病程的关系进行对比研究。结果：软骨损伤总发生率为75%，运动员组为66.7%，非运动员组为79%，非运动员组软骨损伤发生率明显高于运动员组(P＜0.01)，病程超过1年后关节软骨损伤明显加重(P＜0.01)，但两组间差别不显著(P＞0.05)。结论：运动员与非运动员ACL断裂后膝关节软骨损伤率明显增高，损伤程度随病程延长而加重。ACL断裂后继发关节软骨损伤的主要原因是膝关节不稳。Objective To observe the articular cartilage injuries complicated with the rupture of anterior cruciate ligament(ACL)in 21 athletes and 43 non-athletes,and investigate the cause and the pattern of cartilage of knee following the ACL rupture in those patients.Methods The pathologic change,location,degree of cartilage lesion were observed. The relationship between the incidence, occurrent time,degree of cartilage injury and ACL rupture,injured degree of cartilage and the course of ACL rupture were studied.Results The incidence of cartilage injury were 75% in all patients, 66.7% in athletes and 79%in non-athletes. Incidence of cartilage injury in non-athletes was significantly higher than that in athletes (P<0.01).Incidence of serious injury of cartilage in the course more than 1 year was significantly higher than that less than 1 year (P<0.01),but there were no statistical difference between the two groups.Conclusion The incidence of articular cartilage injury following ACL rupture were significantly raised in athletes and non-athletes. The longer the ACL ruptured, the more serious the cartilage injured. Results indicated that articular cartilage injuries in the ACL rupture knee were mainly caused by the instability of knee.中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)0129-302
