For 714 consecutive patients who underwent autogenous patellar tendon graft anterior cruciate ligament reconstructions we intraoperatively measured intercondylar notch width. We prospectively recorded height, weight, sex, and which patients subsequently tore their contralateral anterior cruciate ligament or the 10-mm autograft. The patients were divided into two groups based on notch width (group 1, < or = 15 mm; group 2, > or = 16mm. The mean notch width was 13.9 +/- 2.2 mm for women and 15.9 +/- 2.5 mm for men. There was no statistically significant difference in notch width between height groups for women or men. Analysis showed that, with height and weight as covariates, women had statistically significantly narrower notches than men. Twenty-three of 388 patients in group 1 and 4 of 326 patients in group 2 tore their contralateral anterior cruciate ligaments. Within groups, no statistically significant differences in contralateral tear rates existed between men and women. Once the men and women had reconstructions with equally sized 10-mm autografts, there was no difference in graft tear rate between groups or between men and women. Our results show that patients with narrower notches have a higher incidence of tearing their contralateral anterior cruciate ligament. After reconstruction with a 10-mm autograft, the incidence of graft rupture is the same for men and women.
对于714例连续接受自体髌腱移植重建前交叉韧带的患者，我们在术中测量了髁间切迹宽度。我们前瞻性地记录了患者的身高、体重、性别，以及哪些患者随后发生了对侧前交叉韧带撕裂或10毫米自体移植物撕裂。根据切迹宽度将患者分为两组（第1组，≤15毫米；第2组，≥16毫米）。女性的平均切迹宽度为13.9±2.2毫米，男性为15.9±2.5毫米。女性或男性的身高组之间切迹宽度无统计学显著差异。分析表明，以身高和体重作为协变量，女性的切迹在统计学上显著窄于男性。第1组的388例患者中有23例、第2组的326例患者中有4例发生了对侧前交叉韧带撕裂。在组内，男性和女性之间的对侧撕裂率无统计学显著差异。一旦男性和女性使用同样大小的10毫米自体移植物进行重建，组间或男性与女性之间的移植物撕裂率没有差异。我们的结果表明，切迹较窄的患者对侧前交叉韧带撕裂的发生率较高。使用10毫米自体移植物重建后，男性和女性的移植物破裂发生率相同。
