We analyzed the knee function in 19 consecutive patients with chronic instability after an anterior cruciate ligament rupture. Muscle strength, standing balance, activity level, functional knee score, and a performance test were evaluated. Reduced quadriceps muscle strength compared with the noninjured limb was associated with reduced performance as measured by the one-leg hop test and the Lysholm knee score. No weakness in the hamstrings was found. The patients had impaired standing balance with increased body sway in the frontal plane when standing on both the injured and noninjured limb.
我们分析了19例前交叉韧带断裂后慢性不稳定的连续患者的膝关节功能。评估了肌肉力量、站立平衡、活动水平、膝关节功能评分和一项性能测试。与未受伤肢体相比，股四头肌力量降低与单腿跳测试和Lysholm膝关节评分所衡量的表现下降相关。未发现腘绳肌无力。患者在受伤和未受伤肢体站立时，站立平衡均受损，额面内身体摆动增加。
