Purpose: To determine if rofecoxib 50 mg administered 1 hour preoperatively to patients undergoing arthroscopic knee surgery reduces postoperative pain, provides a narcotic-sparing effect, and reduces time spent in recovery.
Type of study: Prospective, randomized, double-blinded clinical trial.
Methods: Fifty patients (age range, 30 to 60 years) undergoing knee arthroscopy under spinal anesthesia were randomized to receive either 50 mg of rofecoxib or placebo 1 hour preoperatively. Postoperatively, pain was assessed in recovery, 8 hours postoperatively, and 24 hours postoperatively, using a 100-mm visual analog scale. Pain medication usage was monitored for 24 hours and time in recovery room was determined. Mann-Whitney tests determined significance between groups.
Results: Patients in the rofecoxib group showed significantly lower pain scores at 8 and 24 hours postoperatively. They also showed a significant reduction in postoperative narcotic consumption.
Conclusions: Rofecoxib 50 mg as a single preoperative dose should be considered as part of a perioperative analgesic plan in arthroscopic knee surgery.
Level of evidence: Level I, Therapeutic Study (randomized controlled trial).
