目的探讨膝关节骨性关节炎 (KOA)的中医辨证分型与MRI表现的相关 性，为临床诊疗提供依据。方法 对我 院72例KOA患者进行中医辨证分型：筋 脉瘀滞型(22例)，湿注骨节型(23例) 和痰瘀交阻型(27例)。然后进行MRI检 查，分析3种证型与各种MRI表现之间的 相关性。结果 72例患者均发生关节软 骨及半月板损伤；滑膜增厚以湿注骨节 型发生率最高(86.96%)，与筋脉瘀滞型 和痰瘀交阻型比较差异有统计学意义(P ＜0.01)；骨质增生以痰瘀交阻型发生率 最高(85.2%)，与筋脉瘀滞型和湿注骨节 型比较差异有统计学意义(P＜0.01)；关 节游离体形成以痰瘀交阻型发生率最高 (37.0%)，与筋脉瘀滞型比较差异有统计 学意义(P＜0.05)。结论 KOA中医证型 与MRI表现有一定的相关性，MRI在一定 程度上可以作为不同中医证型的辨证参 考。

Objective To explore the correlation between TCM syndrome differentiation types of knee osteoarthritis (KOA) and its MRI changes,so as to provide evidence for clinical diagnosis and treatment. Methods According to the standards of diagnosis and treatment based on overall analysis of symptoms and signs of TCM,72 patients with KOA were divided into 3 types:type of stagnation of tendons and muscles (22 cases),type of dampness infusion into bone and joints (23 cases) and type of inter-obstruction of phlegm and stasis (27 cases).All patients were performed MRI examination, in order to find out the correlation between syndrome differ classification of KOA and its MRI changes. Results 72 cases occurred with articular cartilage and meniscus injury.The incidence of synovial thickening of type of dampness infusion into bone and joints was the highest among the three types (P<0.01).The incidence of bone hyperplasia of type of inter-obstruction of phlegm and stasis was the highest among the three types (P<0.01).The incidence of joint free body formation of type of inter-obstruction of phlegm and stasis was the highest among the three types (P<0.05). Conclusion There is certain correlation between TCM syndrome differentiation types of KOA and its MRI changes.MRI could be used as a reference for different types of TCM syndromes.
