ANALGESIA FOR KNEE SURGERY:EPIDURAL FEMORAL/SCIATIC NERVE BLOCKS

摘要

The medial articular nerve (MAN). It arises from the saphenous nerve (SN)- Occasionally, it will receive supplementary fibers (SF) from the obturator and/or femoral nerves. It supplies the medial, posterior, and anterior aspects of the joint and may even send branches to the anterior attachment of the posterior cruciate ligament.The posterior articular nerve (PAN). The posterior articular nerve arises by two separate branches: PAN-1 (arises directly from the tibial nerve) and PAN-2 (arises from a muscular branch of the tibial nerve). It supplies mainly the posterior and posteromedial aspects of the joint.The lateral articular nerve (LAN). It arises from the common peroneal nerve (CP). It serves the lateral collateral ligament (LCL) and the lateral portion of the joint capsule. (O'Connor and Woodbury, 1982).
