Biomechanical studies show one or 2 ligaments provide the primary passive restraint for each plane of knee stability with the remaining ligaments having a secondary helping role. Correct interpretation of clinical laxity tests and surgical treatment of instability requires this subdivision. Functional stability of the knee is a primary treatment goal after ligament injury, but is too often short-term, relying on muscle control alone without the fine-tuning action of the ligamentous system. If there is abnormal laxity on the clinical examination, there is an increased risk for joint wear, cartilage deterioration and arthritis on a long-term basis.
生物力学研究表明，一条或两条韧带为膝关节每个平面的稳定性提供主要的被动约束，其余韧带起次要的辅助作用。对临床松弛试验的正确解读以及对膝关节不稳定的手术治疗需要这种细分。韧带损伤后，膝关节的功能稳定性是主要治疗目标，但往往只是短期的，仅依靠肌肉控制，而缺乏韧带系统的微调作用。如果临床检查发现有异常松弛，从长期来看，关节磨损、软骨退变和关节炎的风险会增加。
