The purposes of this study were to report degenerative changes that coexist with a symptomatic torn discoid lateral meniscus in adults and to analyze the factors associated with the accompanied degenerative changes. From 1997 to 2008, 329 knees in the 305 patients were included. Associations between the status of the meniscus and the coexisting degenerative changes on the images and the arthroscopic findings were statistically analyzed. Marginal osteophyte was seen on conventional radiography in 118 patients (36%). Ninety patients (27%) had arthroscopically confirmed chondral lesion. Age, duration of symptoms, the type of meniscus, the type of tear and the magnetic resonance image classification were associated with the formation of the marginal osteophyte and chondral lesion on univariate analysis (P < 0.05). After conducting multivariate analysis, the type of tear and magnetic resonance image classification had a statistically significant association with the severity of marginal osteophyte and chondral lesion (P < 0.05).
本研究的目的在于报告成人伴有关节症状的盘状撕裂外侧半月板退行性改变，并分析与伴发退行性改变相关的因素。1997 年至 2008 年，305 例患者中的 329 个膝关节纳入研究。对半月板状态与影像学和关节镜检查结果之间的伴发退行性改变进行了统计学分析。118 例患者（36%）常规 X 线片上可见边缘骨赘。90 例患者（27%）经关节镜证实有软骨损伤。单因素分析显示，年龄、症状持续时间、半月板类型、撕裂类型和磁共振成像（MRI）分类与边缘骨赘和软骨损伤的形成有关（P < 0.05）。多因素分析显示，撕裂类型和 MRI 分类与边缘骨赘和软骨损伤的严重程度有统计学显著关联（P < 0.05）。
