[Why choose loco-regional anesthesia for knee surgery?].

The advantages and disadvantages of both general and local or regional anaesthesia for knee surgery are presented and the patient characteristics enumerated. Regional anaesthesia reduces the frequency of postoperative thrombo-embolic accidents, diminishes blood-loss and permits good postoperative analgesia. Thus it seems to achieve better results in respect to morbidity and mortality. It requires the patient's consent and acceptance by the surgeons as well as appropriate operating theater management.
