| 摘 要： | 目的 通过膝关节多角度屈曲MR扫描，观察膝关节炎髌股关节软骨损伤的位置，判断最容易引起髌股关节软骨损伤的运动角度，探讨膝关节的安全运动方式。方法 对22例骨关节炎患者的膝关节分别在伸直位和被动屈曲0°、10°、20°、30°、40°、50°、60°的状态下进行快速自旋回波质子加权像加脂肪抑制序列（PD-TSE-FS）扫描，矢状位图像上观察髌股关节软骨损伤的位置。结果 髌股关节软骨内T2WI信号异常4处，局限性软骨变薄20处，关节软骨局限性缺损12处。膝关节被动屈曲时，软骨损伤在30°~60°内均有对合情况，对合最多的角度为40°，在<30°屈曲角度扫描中仅发现1例软骨损伤对合的病例。结论 膝关节屈曲30°~60°时髌骨软骨与股骨滑车软骨损伤在对应面出现的频率最高。屈曲<30°时髌骨软骨与股骨滑车软骨损伤在对应面出现的频率较低。

| Abstract: | Objective To determine the violable location of cartilage lesions in knee osteoarthritis (OA) patients and to explore the safety movement of the knee joint, by MR scanning at multi-angle flexion.Methods Patients with knee OA were performed PD-TSE-FS MR examination in straight position and knee flexed at 10, 20, 30, 40, 50, 60 degree separately. The location of cartilage lesions were observed in sagittal images.Results The abnormal signal of cartilage in T2WI sequence were found at 4 patellofemoral joints, the localized thinner cartilage were found at 20 lesions, and localized defect were found at 12 lesions. Correspondence cartilage lesions of patellofemoral joint were predominant at 40 degree (ranged from 30 to 60 degree) in knee flex position. One cartilage defect lesion of patellofemoral joint was found at less than 30 degree.Conclusion The cartilage lesions in patellar and femoral trochlear occur in the corresponding surface with high frequency during the knee flexion ranged from 30 to 60 degree. While it shows lower frequency during the knee flexion less than 30 degree. |
