This investigation utilized gross dissections, histological preparations, and neurophysiologic experiments to gain an improved understanding of the innervation of the human knee. Anatomical illustrations represent the findings of dissections of 15 fresh amputation specimens. Neurohistologic preparations using silver staining techniques demonstrate the rich innervation of the soft tissues of the knee, and a variety of specialized receptors are identified. In 10 subjects with normal knees, and experimentally produced knee effusion of 60 cc was found to result in profound inhibition of reflexly evoked quadriceps contraction. Clinical implications of the anatomical and physiologic data are discussed.
本研究采用大体解剖、组织学制片和神经生理学实验，以更好地了解人类膝关节的神经支配情况。解剖学插图展示了15个新鲜截肢标本的解剖结果。使用银染技术的神经组织学制片显示了膝关节软组织丰富的神经支配，并识别出多种特殊感受器。在10名膝关节正常的受试者中，发现实验性产生60毫升膝关节积液会导致反射诱发的股四头肌收缩受到显著抑制。文中讨论了解剖学和生理学数据的临床意义。
