摘　　要：目的通过膝关节改良Insall-Salvati(MIS)指数运用MR分析髌骨高度与前交叉韧带(ACL)撕裂的相关性。方法回顾性分析50例ACL撕裂患者的资料,测量其髌韧带止点上缘到髌骨关节面下极距离、髌骨关节面长度并计算其MIS指数,与50例膝关节正常者MRI资料分别进行对比分析。结果 50例ACL撕裂者髌韧带止点上缘到髌骨关节面下极距离、MIS指数分别为(52.80±5.38)mm、1.89±0.21,正常组则分别为(48.44±3.75)mm、1.77±0.20,二组数据比较,差异具有显著统计学意义(P<0.05),二组间髌骨关节面长度差异无统计学意义(28.12±3.28)mm;(27.58±2.72)mm,(P>0.05)。结论 ACL撕裂与髌骨高度具有一定的相关性,MIS指数可以作为评估ACL撕裂的一个重要参数。Objective By use of modified Insall-Salvati ratio, to discuss the relationship between anterior cruciate ligament （ACL） tear and patella height. Methods MRI of 50 knees with ACL tear were retrospectively reviewed. The length from patellar tendon to patellar articular surface and patellar articular surface length were measured, and the modified Insall-Salvati ratio obtained from MRI of the knee were compared with 50 control subjects with normal knee examinations. Results Average of the length from patellar tendon to Patellar articular surface （52.80 ± 5.38） mm vs （48.44 ± 3.75） mm and the modified Insall-Salvati ratio （ 1.89 ±0.21 ） vs （ 1.77 ± 0.20） were significantly greater in the study group than those of the control group （ P 〈 0. 05 ）. Patellar articular surface length was not Significantly different between the two groups （28.12 ± 3.28 ）mm vs （27.58 ± 2. 72 ） mm; （ P 〉 0.05 ）. Conclusion There is a significant association between ACL tear and patella height. The modified Insall-Salvati ratio can be used as an important risk parameter for evaluation of ACL tear.
