Abstract

The purpose of the study was to identify mechanoreceptors in the lateral collateral ligament of the human knee. Ten ligaments from ten fresh cadavers were studied by light microscopy. In addition to free nerve endings, two types of mechanoreceptors were identified. They were located at the femoral and fibular attachments and on the surface of the ligament. These findings support the theory that the lateral collateral ligament of the knee has an anatomic basis for a discriminating afferent flow towards the central nervous system. The neural network of the lateral collateral ligament of the knee may play a role in regulating the contraction of muscle groups that are fundamental to knee stability.
