Résumé
The knee is innervated by the femoral, obturator and sciatic nerves giving ten or so articular branches. Knee surgery is a functional surgery causing severe postoperative acute pain and quite often chronic pain. Balanced analgesia must be combined with regional analgesia to ensure postoperative rehabilitation. Continuous femoral nerve blockade promotes early joint mobilisation with fewer side effects when compared to epidural analgesia. Adductor canal block, local infiltration analgesia and IPACK aim to cause less motor weakness than peripheral nerve blocks, at the cost of a lower quality of analgesia beyond the first hours for single shot injection. Each team must define multimodal analgesic pathways that incorporate regional techniques into the perioperative care of patients undergoing knee surgery.
