摘　　要：目的通过CT检查测定单侧复发性髌骨不稳患者双侧胫骨结节股骨滑车沟(TT-TG)距离的数值,了解患侧与健侧是否存在差异。方法对34例单侧复发性髌骨不稳患者行膝关节CT检查,对病史、CT检查数据进行分析。结果 34例患者患侧TT-TG距离为(16.47±3.87)mm,健侧TT-TG距离为(15.61±3.52)mm,两者之间比较差异无统计学意义(t=1.302,P>0.05)。结论单侧复发性髌骨不稳患者患侧与健侧TT-TG无明显差异,临床单独应用TT-TG间距指导诊疗单侧复发性髌骨不稳依据不足。Objective To provide the anatomic parameters and CT data of patients who diagnosed with recurrent unilateral patellar instability about knee joints for the tibial tuberosity-trochlear groove distance,and assess the difference between symptomatic knee and asymptomatic knee. Methods Thirty-four patients who diagnosed with recurrent unilateral patellar instability were involved in this study. CT scans were checked on both knees,and the data were analyzed. Results Mean TT-TG distance in the symptomatic knee was（ 16. 47 ± 3. 87） mm,compared to（ 15. 61 ±3. 52） mm in the asymptomatic knee（ t = 1. 302,P〉0. 05）. Tibial TT-TG was not significantly different between stable and unstable knees. Conclusions The lack of difference in TT-TG distance between stable and unstable knees suggests that TT-TG distance alone may not be a decisive element in establishing therapeutic choices for patellar instability.
