The synergistic action of the ACL and the thigh muscles in maintaining joint stability was studied experimentally. The EMG from the quadriceps and hamstring muscle groups was recorded and analyzed in three separate experimental procedures in which the knee was stressed. The test revealed that direct stress of the ACL has a moderate inhibitory effect on the quadriceps, but simultaneously it directly excites the hamstrings. Similar responses were also obtained in patients with ACL damage during loaded knee extension with tibia subluxation, indicating that an alternative reflex arc unrelated to ACL receptors was available to maintain joint integrity. The antagonist muscles (hamstrings) were clearly demonstrated to assume the role of joint stabilizers in the patient who has a deficient ACL. The importance of an appropriate muscle-conditioning rehabilitation program in such a patient is substantiated.
通过实验研究了前交叉韧带（ACL）与大腿肌肉在维持关节稳定性方面的协同作用。在三种不同的对膝关节施加压力的实验过程中，记录并分析了股四头肌和腘绳肌组的肌电图。测试表明，ACL受到的直接应力对股四头肌有中度抑制作用，但同时它直接兴奋腘绳肌。在伴有胫骨半脱位的负重膝关节伸展过程中，ACL损伤患者也获得了类似的反应，这表明存在一个与ACL感受器无关的替代反射弧来维持关节完整性。在ACL功能不全的患者中，拮抗肌（腘绳肌）明显被证明起到了关节稳定器的作用。证实了在此类患者中进行适当的肌肉调节康复计划的重要性。
