Abstract

The nerve supply of the knee joint in cattle was studied by dissections on sucking-calves and by nerve staining of section series of foetal joints. Four distinct nerves to the joint were observed. They were given off by the N. saphenus to the medial and distal anterior regions of the joint, by a branch from the N. femoralis within the M. rectus femoris, to the middle patellar ligament, by the N. tibialis to the posterior capsule, and by the N. peronaeus to the region of the lateral collateral ligament. The microscopical studies revealed minor additional bundles to the posterior capsular r egion from the N. saphenus, the N. tibialis, and the N. peronaeus, as well as some bundles from the N. femoralis to the M. vastus intermedius, possibly innervating the proximal part of the femoro-patellar joint capsule. Many of the largest fibres ramified on or near the surfaces of the collateral ligaments and the middle patellar ligament.
