目的通过对大骨节病(Kaschin Beck disease,KBD)患者膝关节中髌骨及髌股关节形态学参数的X线观测,探寻KBD的膝关节形态变化规律,为临床诊疗提供参数资料,为关节置换提供参数支持。方法对84例KBD住院患者的膝关节的X线片及相关的临床资料进行了回顾性分析。在X线片上进行了Kellgren-Lawrence及髌骨分型,测量了Insall指数、外侧髌股角、沟角、适合角、髌骨外移率、髌股指数等形态学参数与症状、疗效之间相关性。结果参数严重性越高,KBD临床表现越重,临床疗效越差,KBD临床症状越重,效果越差。结论膝关节X线参数可以作为KBD治疗效果和预后判断的重要参数。
OBJECTIVE: To investigate the morphological changes of knee joint in KBD by analyzing X-ray of the patellar and patellofemoral joint in knee joint of patients with Kaschin Beck disease (KBD) and to provide parameter data for clinical diagnosis and treatment for joint replacement Parameter support. Methods Eighty - four KBD inpatients with knee joint X - ray and related clinical data were retrospectively analyzed. Kellgren-Lawrence and patellar classification were performed on X-ray films. The correlations between the morphological parameters such as Insal index, lateral patellofemoral angle, gullet angle, apical angle, patellar shift, and patellofemoral index and their symptoms and curative effects were measured . Results The higher the severity of the parameters, the more severe the clinical manifestations of KBD, the poorer the clinical efficacy, the more severe clinical symptoms of KBD, the worse the effect. Conclusion X-ray parameters of knee joint can be used as an important parameter of KBD treatment and prognosis.
