The purpose of this study was to investigate the relation between isolated discoid lateral meniscus (DLM) tears and the presence of articular cartilage lesions.
From January 2010 to January 2012, 252 consecutive patients diagnosed with an isolated DLM tear during an arthroscopic procedure were included in this study. Demographic variables, including gender, age, body mass index (BMI), traumatic history, time course, and date of the DLM tear, were recorded. The relation between DLM tears and the presence of articular cartilage lesions was analyzed by the χ(2) test. Logistic regression analysis was used to analyze the relation between these variables and articular cartilage lesions.
Of the patients with DLM tears, 67 (26.6%) also had articular cartilage lesions. The most common type of DLM tear was the complex tear (46.8%). The most common location of articular cartilage lesions was the lateral tibial plateau (11.6%). Lesions on the opposing articular surfaces of the lateral compartment and patellofemoral joint of the knee were found in 12 patients (4.8%) and 11 patients (4.4%), respectively. There were no significant differences in the incidences of articular cartilage lesions in patients with different types of DLM tears (P > .05). Gender (odds ratio [OR], 2.289; P = .012), BMI (OR, 1.991; P = .023), and time course (OR, 2.050; P = .034) were significantly associated with articular cartilage lesions.
DLM tears were more common in the context of degenerative tears. There was no significant difference in the incidence of articular cartilage lesions among patients with different types of DLM tears. Female patients, patients with a BMI greater than 23.0 kg/m(2), or patients with a time course of greater than 6 months were more frequently observed to also have articular cartilage lesions.

本研究旨在探讨孤立性盘状外侧半月板（DLM）撕裂与关节软骨损伤之间的关系。
2010 年 1 月至 2012 年 1 月，对 252 例关节镜检查中诊断为孤立性 DLM 撕裂的患者进行了本项研究。记录了患者的人口统计学变量，包括性别、年龄、体重指数（BMI）、外伤史、病程和 DLM 撕裂的时间。采用卡方检验分析 DLM 撕裂与关节软骨损伤的关系。采用 Logistic 回归分析这些变量与关节软骨损伤的关系。
252 例 DLM 撕裂患者中，67 例（26.6%）同时存在关节软骨损伤。最常见的 DLM 撕裂类型是复合型撕裂（46.8%）。最常见的关节软骨损伤部位是外侧胫骨平台（11.6%）。在 12 例（4.8%）和 11 例（4.4%）患者中分别发现了外侧间室和髌股关节对向关节面的损伤。不同类型 DLM 撕裂患者的关节软骨损伤发生率无显著差异（P>0.05）。性别（比值比[OR]，2.289；P=0.012）、BMI（OR，1.991；P=0.023）和病程（OR，2.050；P=0.034）与关节软骨损伤显著相关。
DLM 撕裂更常见于退行性撕裂。不同类型 DLM 撕裂患者的关节软骨损伤发生率无显著差异。女性患者、BMI 大于 23.0kg/m²的患者或病程大于 6 个月的患者更容易同时发生关节软骨损伤。
