116例膝关节滑膜炎的X线诊断初步研究

目的 分析滑膜炎的Ｘ线特征，提出简便准确的Ｘ线诊断方法。方法 对３０例膝关节侧位Ｘ线平片的滑膜及髌下脂肪垫的正常Ｘ线表现与１１６例滑膜炎的Ｘ线表现进行了对比分析。结果 发现平时临床上有膝关节不明原因疼痛，而Ｘ线平片又无骨质异常改变的病例中，可见其膝关节侧位片上，有不同程度的滑膜增厚，或／和髌下脂肪垫水肿。结论 Ｘ线平片可对滑膜炎作出诊断，但对其病因尚需进一步明确。

X-ray features of synovitis of knee joint:study 116 cases

Objective To analyze X ray characteristics of synovitis of knee joint and suggest a simple diagnostic method. Methods The X ray films of knee joint from lateral view of 30 normal individuals and of 116 patients with synovitis were compared for the features of synovialis. Results Thickening of synovialis and/or edema of infrapatellar fat pad was found in those with knee joint pain of unknown origin, but without abnormal bony changes by radiography. Conclusion X ray film can diagnose synovitis of knee joint, but the etiology needs further investigation.
