Sixteen males (mean age 30 ± 8 years), all possessing an old rupture of the anterior cruciate ligament which had not been repaired surgically, underwent a biomechanical evaluation of a one-leg long hop using opto-electronic motion analysis and ground reaction force analysis. In concordance with previous findings, the length of a one-leg long hop on the injured leg was shorter than on the non-injured leg. Furthermore, performance of the non-injured leg was impaired compared to a reference group. There was no significant difference in knee flexion angles at impact, but there was a lower eccentric knee angular velocity in the injured leg, 597°/s (SD 101), as compared with 701°/s (SD 130) for the non-injured leg (P < 0·01). No statistically significant differences were found for the reaction force components. The level of evaluation, mechanisms for the provocation of knee joint instability and possible adaptations are discussed.
16名男性（平均年龄30±8岁），均患有陈旧性前交叉韧带断裂且未接受手术修复，采用光电运动分析和地面反作用力分析对单腿跳远进行了生物力学评估。与先前的研究结果一致，伤腿的单腿跳远长度比未受伤腿短。此外，与参照组相比，未受伤腿的表现也受到了损害。撞击时膝关节屈曲角度没有显著差异，但伤腿的膝关节离心角速度较低，为597°/秒（标准差101），而未受伤腿为701°/秒（标准差130）（P<0.01）。在反作用力分量方面未发现统计学上的显著差异。本文讨论了评估水平、膝关节不稳定的激发机制以及可能的适应性。
