Post-operative checks of 57 cases of anterio-medial knee instability (II and III degree) were carried out over a period of 1-4 years after operation. "Subjective knee stability" was documented on three levels in a questionnaire as not "giving way". "Objective knee stability" was evaluated by measuring 30 degree anterior drawer displacement using the KT 1000 instrument. Strength of the thigh muscles of both legs for different power parameters under isokinetic load was measured with the Cybex II instrument system. No significant correlation between subjective perception of knee instability and instrumented measured anterior drawer displacement could be shown in a T-test. Individuals with higher "objective stability" or higher "subjective stability" level had both generally stronger tight muscle parameters, specially for knee extension. Most of our interest had the group of individuals assumed "subjective stable" but having quite a large anterior drawer displacement phenomena like ACL deficit knee. This group is characterized by higher 10 degree power parameters for knee extension and flexion and lower H/Q-quotient. This is supposed to be indication to functional adaptation of the neuro-muscular system to altered biomechanic situation after ACL disruption or reconstruction. Electromyographic studies should follow to test this hypothesis.
对57例膝前内侧不稳定（II度和III度）患者术后1至4年进行了检查。在一份问卷中，“主观膝关节稳定性”在三个级别上记录为不“打软腿”。使用KT 1000仪器通过测量30度前抽屉移位来评估“客观膝关节稳定性”。使用Cybex II仪器系统测量双腿在等速负荷下不同功率参数时的大腿肌肉力量。在T检验中，未发现膝关节不稳定的主观感受与仪器测量的前抽屉移位之间存在显著相关性。“客观稳定性”较高或“主观稳定性”水平较高的个体，其紧张肌肉参数通常都较强，尤其是在膝关节伸展方面。我们最感兴趣的是那些被认为“主观稳定”但却存在相当大的前抽屉移位现象的个体组，比如前交叉韧带缺失的膝关节。该组的特点是膝关节伸展和屈曲的10度功率参数较高，而H/Q商较低。这被认为是神经肌肉系统对前交叉韧带断裂或重建后生物力学改变情况的功能适应迹象。应进行肌电图研究以验证这一假设。
