胫骨结节-股骨滑车沟距离及相关参数与非接触性前交叉韧带损伤的关系研究

A clinical study on the relationships between tibial tubercle-trochlear groove distance and its related parameters and noncontact anterior cruciate ligament injury

目的:探讨胫骨结节-股骨滑车沟(tibial tubercle-trochlear groove,TT-TG)距离及相关参数与非接触性前交叉韧带(anterior cruciate ligament,ACL)损伤的关系。方法:收集22例非接触性ACL损伤患者(损伤组)和25例ACL完好者(对照组)的膝关节MRI。在收集到的MRI上测定TT-TG距离、股骨滑车沟长度(trochlear length,TL)、股骨滑车沟宽度(trochlear width,TW)、髌骨长度(patellar length,PL)及髌骨宽度(patellar width,PW)。结果:损伤组的TT-TG距离大于对照组[(11. 94±2. 63) mm,(10. 18±2. 13) mm,t=21. 162,P=0. 015]; 2组的(TT-TG)/TL、(TT-TG)/TW、(TT-TG)/PL、(TT-TG)/PW比较,组间差异均无统计学意义(0. 93±0. 27,0. 83±0. 23,t=18. 191,P=0. 182; 0. 33±0. 08,0. 31±0. 05,t=32. 112,P=0. 211; 0. 38±0. 08,0. 34±0. 06,t=24. 455,P=0. 092; 0. 29±0. 07,0. 27±0. 05,t=29. 175,P=0. 153)。结论:TT-TG距离可能与非接触性ACL损伤发生有关,但TT-TG距离相关参数与非接触性ACL损伤的发生无明显关系,能否将其作为预测非接触性ACL损伤的可靠指标还有待进一步研究。

Objective:To explore the relationships between tibial tubercle-trochlear groove(TT-TG)distance and its related parameters and noncontact anterior cruciate ligament(ACL)injury.Methods:The knee MRI images of 22 patients with noncontact ACL injury(injury group)and 25 patients with intact ACL(control group)were collected.The TT-TG distance,femoral trochlear length(TL),femoral trochlear width(TW),patellar length(PL)and patellar width(PW)were measured on the collected MRI images.Results:The TT-TG distances were greater in injury group compared to control group(11.94+/-2.63 vs 10.18+/-2.13 mm,t=21.162,P=0.015).There was no statistical difference in(TT-TG)/TL,(TT-TG)/TW,(TT-TG)/PL and(TT-TG)/PW between the 2 groups(0.93+/-0.27 vs 0.83+/-0.23,t=18.191,P=0.182;0.33+/-0.08 vs 0.31+/-0.05,t=32.112,P=0.211;0.38+/-0.08 vs 0.34+/-0.06,t=24.455,P=0.092;0.29+/-0.07 vs 0.27+/-0.05,t=29.175,P=0.153).Conclusion:The TT-TG distance may be related to the occurrence of noncontact ACL injury,while the TT-TG distance-related parameters have no obvious relation to the occurrence of noncontact ACL injury,so further study is needed to examine whether it can be used as a reliable prediction indicator of noncontact ACL injury.
