Objective: Preoperative rehabilitation of the range of motion has a great impact on the postopera-tive joint functions in patients undergoing knee arthroscopies, but effective functional exercise may not be practicable due to severe pain. Although early pre-emptive analgesia may provide sufficient pain control, controversies still exist regarding related severe adverse effects caused by the analgesics. The aim of this study was to investigate the effectiveness of early pre-emptive analgesia on postoperative joint range of motion in patients undergoing arthroscopy. Methods: Thirty four patients undergoing arthroscopic partial menisectomy were divided into two groups: the early pre-emptive analgesia group and the non-pre-emptive analgesia group. Knee range of motion was measure before surgery and at the 4th and 12th postoperative weeks. Results: All patients regained full extension of the knee before discharge. The knee flexion angles of patients in the analgesic group were higher than those of patients in the non-analgesic group before surgery and at 4 weeks postoperatively. There was no statistical difference in flexion angles between two groups at the 12th postoperative week. Conclusion: Early pre-emptive analgesia could accelerate the rehabilitation of range of motion in patients undergoing arthroscopic menisectomy.
