RESUMO

The mechanoreceptor innervation of fibular collateral ligaments from human knee joints is described. While a small number of 'non-Paciniform' endings were identified in 5 optimally-stained ligaments, 'Paciniform' endings were not identified. These 'non-Paciniform endings' were variable in shape, but each consisted of an encapsulated arborisation of neurites embedded in a granular matrix. The significance of these findings is discussed as they relate to (i) discrepancies of the extent to which certain periarticular tissues are innervated, and (ii) the role of periarticular mechanoreceptors in initiating protective muscular reflexes.
