摘　　要：目的测量和计算胫骨结节-股骨滑车间距离（TT-TG距离）,胫骨结节-股骨滑车间垂直距离（TT-TE距离）和TTTG/TT-TE,分析TT-TG/TT-TE在髌骨不稳中的应用价值,并比较其和TT-TG距离的优缺点。方法选择髌骨不稳的患者30例,无髌骨不稳的患者30例,分别测量两组TT-TG距离、TT-TE距离、TT-TG/TT-TE。分析比较两组数据之间的差异和临床应用价值。结果两组TT-TG距离和TT-TG/TTTE之间差异有统计学意义（P〈0.001）;TT-TE距离差异无统计学意义。结论 TT-TG距离评价髌骨不稳有重要意义,TT-TG/TT-TE可消除个体差异的影响,能更好地评价髌骨不稳,特别是对于TT-TG距离处于临界值范围15-20 mm的患者,为临床上是否需要做胫骨结节内移提供了参考依据。Objective To meassure and calculate the tuberositas tibae-trochlear groove（ TT-TG） distance,the perpendicular distance between the entrance of the chondral trochlear groove and the onset of the patellar tendon at the tibial tubercle（ TT-TE） distance,and TT-TG / TT-TE,analyse the values of TT-TG / TT-TE in patellar instability and compare the differences between TT-TG and TT-TG / TT-TE in patients and control groups. Methods Knee magnetic resonance images（ MRIs） were collected from 30 patients with lateral patellar instability and from 30 control subjects. Student t test was used to compare the TT-TG distance,TT-TE distance and TT-TG / TT-TE between patients and the controls. Results TT-TG distance and TT-TG / TT-TE had significant differences（ P 0. 001）,TT-TE distance didn＇t have any differences between patients and the controls. Conclusion It is a significant value for TT-TG distance to the patellar instability,TT-TG / TT-TE which takes individual joint size into consideration presents more valuable than TT-TG distance,especially those whose TT-TG distance was a threshold between 15 and20 mm for medial transfer of the tibial tubercle.
