摘要
目的:探讨髌骨不稳人群与正常人群髌骨运动轨迹的不同,为临床诊断提供依据。方法:自2012年7月至2016年12月,共纳入35例(35膝)髌骨不稳人群:其中男性11例,女性24例。纳入健康人群10例(10膝),其中男性4例,女性6例。在膝关节0°,30°,45°,60°及90°位置进行膝关节CT扫描,使用Mimics10.01对影像资料进行分析,参数包括髌骨倾斜、外移、旋转。结果:在膝关节位于0°~90°位置时,髌骨倾斜、外移、旋转与正常人群相比差异均有统计学意义(P<0.05)。在0°~60°,髌骨不稳人群髌骨倾斜及外移逐渐减小,60°~90°时增大;膝关节曲屈0°~30°时,髌骨旋转逐渐减小;在30°~45°位置时,逐渐增大;在45°~60°时,旋转有所下降;在60°~90°时,其旋转程度增大。结论:髌骨不稳人群与正常人群相比,两组动态髌骨运动轨迹存在差异。
Objective：To explore the difference of patellar track between the patellar instability people and healthy people,and to provide the basis for clinical diagnosis.Methods：A total of 35 patients（35 knees）with patellar instability were enrolled from July 2012 to December 2016,including 11 males and 24 females,and 10 healthy people（10 knees）,including 4 males and 6 females.The knee joint CT scan was performed at 0°,30°,45°,60°,90°,and Mimics10.01 was used to analyze the imaging data,including patellar tilt,external movement and rotation.Results：There was statistic difference between the 2 groups at 0°~90° on patellar shift,patellar tilt and patellar rotation.At 0°~60°,patellar shift and patellar tilt gradually decrease,and at 60°~90°,it is gradually increase.For patellar rotation,it is gradually decrease at 0°~30°and 30°~45°,and at 30°~45°and 60°~90°,it is gradually increase.Conclusion：Based on the comparison of the results,it is found that the differences in the dynamic patella trajectory between the two groups were obvious.
