Patient satisfaction with treatment in the operating room and following arrival to the postanaesthesia care unit was evaluated numerically (0-10), using the numeric rating scale (NRS), with 0 indicating lowest, and 10 highest possible satisfaction as rated by the patient. Intensity of postoperative pain was evaluated by NRS. Overall condition and functional capacity were evaluated using a 3 -point scale (good / moderate / poor). Health-related quality of life was measured using the RAND-36-instrument.
