【摘要】目的 对髌股关节进行CT测量，确定有无髌股排列异常。方法 对一组20例40侧膝关节进行CT检查，分别在股四头肌收缩和松弛状况下扫描，对CT图像进行测量。结果 40膝中有10膝为静力性髌骨外侧半脱位，另30膝中有16膝为动力性髌骨半脱位；40膝中11膝为静力性髌骨外倾，另有7膝为动力性髌骨外倾。结论 髌股关节CT检查可精确测量髌股力线，了解股四头肌对髌骨的影响及髌旁支持带的紧张程度。

【 Abstract 】 Objective Forthe determination of the presence of malalignment of the patellofemoral joint, evaluationwas done with CT scanning. Methods Twenty patients (40 knees) with orwithout quadriceps contraction were examined by CT scanning and the CT images weremeasured. Results There were 10 knees with static patellar lateral subluxation, 16 knees with dynamic lateral subluxation, 11 knees with static patellarlateral tilt and 7 knees with dynamic tilt. Conclusion The patellofemoralalignment, affection of quadriceps and extent of tightness of retinaculum may be preciselydetermined by CT measurement.
