目的：膝骨关节炎（OA）患者经常发生半月板撕裂。我们研究的目的是确定磁共振成像 (MRI) 发现的半月板损伤是否与膝关节 OA 患者膝关节疼痛的严重程度或半月板症状的频率相关。方法：我们利用骨关节炎研究中半月板撕裂 (MeTeOR) 试验的数据进行了一项横断面研究。我们将半月板损伤分为以下几类：根部撕裂；浸渍；长短复合或水平撕裂；和简单的眼泪。受试者完成了西安大略大学和麦克马斯特大学骨关节炎指数 (WOMAC) 疼痛量表以及半月板症状频率的调查。我们使用多变量一般线性模型来评估半月板损伤与 1）疼痛严重程度之间的关系； 2) 调整人口统计和放射学特征后的半月板症状。在进一步分析中，根部撕裂被视为二元变量。结果：分析包括 227 个膝盖。 19% 存在根部撕裂，14% 存在浸渍，22% 存在长复合或水平撕裂，30% 存在短复合或水平撕裂，14% 存在简单撕裂。牙根撕裂与较高的 WOMAC 疼痛评分相关。对于有牙根撕裂的受试者，调整后的平均 WOMAC 疼痛评分为 45.2（标准误差 (SE) 2.7），对于没有牙根撕裂的受试者，调整后的平均 WOMAC 疼痛评分为 38.7 (SE 1.2) (P = 0.03)。我们没有发现半月板形态和半月板症状频率之间存在统计学上的显着关联。结论：根部撕裂比半月板撕裂或浸渍带来更大的疼痛。我们没有发现半月板损伤和半月板症状之间的关系。 (C) 2017 年国际骨关节炎研究协会。由爱思唯尔有限公司出版。保留所有权利。
Objective: Meniscal tears occur frequently in patients with knee osteoarthritis (OA). The aim of our study was to determine whether meniscal damage identified on magnetic resonance imaging (MRI) is associated with the severity of knee pain or the frequency of meniscal symptoms in patients with knee OA.Methods: We performed a cross-sectional study using data from the Meniscal Tear in Osteoarthritis Research (MeTeOR) trial. We characterized meniscal damage hierarchically as: root tear; maceration; long and short complex or horizontal tears; and simple tears. Subjects completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Scale and a survey of frequency of meniscal symptoms. We used multivariable general linear models to assess the relationships between meniscal damage and 1) pain severity; and 2) meniscal symptoms, after adjusting for demographic and radiographic features. In further analysis root tear was considered as a binary variable.Results: Analysis included 227 knees. Root tears were present in 19%, maceration in 14%, long complex or horizontal tears in 22%, short complex or horizontal tears in 30%, and simple tears in 14%. Root tears were associated with higher WOMAC pain scores. The adjusted mean WOMAC pain score was 45.2 (standard error (SE) 2.7) for those with root tear and 38.7 (SE 1.2) for subjects without root tear (P = 0.03). We did not find statistically significant associations between meniscal morphology and frequency of meniscal symptoms.Conclusion: Root tears were associated with greater pain than meniscal tears or maceration. We did not find a relationship between meniscal damage and meniscal symptoms. (C) 2017 Osteoarthritis Research Society International. Published by Elsevier Ltd. All rights reserved.
