膝骨关节炎病因、X线片及临床表现分析

目的探讨国人膝骨关节炎病因，临床表现和Ｘ线片的相关性，为临床诊治提供依据。方法对骨科门诊膝骨关节炎患者进行病因，临床表现调查，摄单腿站立位膝关节正侧位、髌骨轴位片，分析Ｘ线征象并作骨关节炎分级、分型。结果膝骨关节炎原发性占８７％，继发性占１３％，膝骨关节炎分型：初期型３８％，股型２８．５％，内侧－髌股型２３．２％。随关节炎分类程度的加重，稞症状向严重发展（Ｐ〈０．０１）。胫股角越大，Ｘ线分级趋向病

Analysis of etiology, roentgenography and clinical manifestation of knee osteoarthritis

Objecive To explore the relationship between the etiology and radiological characteristics and clinical manifestations of osteoarthritis (OA)of the knee, providing basis for the treatment. Methods The etiology, clinical manifestations of outdoor patients with osteoarthritis of the knee were investigated, and standing anteroposterior, lateral and axial film of patellofemoral joint analyzed, OA grading, and classification was also evaulated. Results 87% cases were primary,and 13% secondary osteoarthritis. According to the classification of roentgenography,38% were preliminary type,28 5% patellofemoral type and 23.2% for the medio-patellofemoral type. Radiological classification was related with the clinical manifestations ( P <0 01).If the varus and valgus deformity was severer, X ray grading would become severer( P <0 01).Conclusion Primary osteoarthritis of the knee is more common than secondary type. Besides preliminary, patellofemoral and medio patellofemoral type are common. Varus or valgus deformity of knee joint will increase the severity of clinical manifestation of OA of the knee.
