膝关节骨性关节炎半月板退变情况分析

Analysis of meniscus degeneration in osteoarthritis of knee joint

目的 观察半月板在膝关节骨性关节炎中的退变情况 ,探索半月板退变与膝关节骨性关节炎临床表现的关系。方法 对 4 3例行关节清理术的膝关节半月板进行观察 ,根据半月板的退变程度 ,将其分为三型 :粗糙型、磨损型和破裂型。比较各类型退变出现关节间隙压痛、关节交锁、McMurray试验 (+)、Apley试验 (+)的比率并进行统计学分析。 结果 4 3膝 83个半月板中有 6 6个出现退变 ,占79 5 %。粗糙型 34个 ,占 5 1 5 % ;磨损型 2 3个 ,占 34 8% ;破裂型 9个 ,占 13 6 %。各型合并半月板松弛者 14个 ,占 2 1 2 %。比较三种类型中的 4个指标 ,差异无显著性意义 (P >0 0 5 )。结论 膝关节骨性关节炎普遍存在半月板退变 ,由于缺乏典型的临床表现 ,在临床检查中不易发现 ,手术中要避免遗漏对半月板的探查和处理。

Objective To observe the meniscus degeneration of osteoarthritis of knee joint and to explore the relationship between degenerated meniscus and clinical manifestation of osteoarthritis of knee joint Methods 83 menisci in 43 patients were treated with arthroxesis were observed.According to the degree of the degeneration,the degenerated menisci were classified as Rough type,Wear and Tear type and Rupture type.The incidence of tenderness at the joint level,locking,positive Mc Murray test and positive Grinding test of Apley in the three groups were compared statistically.Results 66 menisci(79 5%) were degenerated among 43 knee joints.Of them,Rough type was seen in 34(51 5%),Wear and Tear type in 23(34 8%),Rupture typein 9(13 6%).Combine with Slackness 14(21 2%).There was no significant difference among three types at four indices (P>0 05).Conclusion Most of meniscus were degenerated in osteoarthritis of knee,there are no typical symptoms and signs found in clinical examination.One should pay attention to the condition of the meniscus during surgery render treatment accordingly.
