The suggestion that the knee behaves like a closed kinematic chain has been tested experimentally. The tibial joint surfaces were replaced by a deformable material and new surfaces were moulded by flexion and extension of the knee. The results support the closed kinematic chain theory; the newly moulded joint surfaces strikingly resemble the original joint surfaces. Inferences are drawn to explain why a fracture of the tibial condyle will remould with early mobilisation of the knee; why a jerk is elicited in tests for anterolateral instability; and why a flexion-compression force alone is unlikely to damage the menisci.
膝关节表现得如同一个闭合运动链这一观点已通过实验进行了验证。胫骨关节面被一种可变形材料所替代，并且通过膝关节的屈伸塑造出了新的关节面。结果支持了闭合运动链理论；新塑造的关节面与原始关节面惊人地相似。由此得出一些推论，用以解释为何胫骨髁骨折在膝关节早期活动时会重塑；为何在前外侧不稳定测试中会引发抽搐；以及为何仅屈曲压缩力不太可能损伤半月板。
