BACKGROUND: Gender-related differences in pain have been clearly shown in experimental settings. Clinical studies of such differences have produced conflicting findings. No studies have shown a significant difference in pain experience associated with differences in functional outcomes. Arthroscopic anterior cruciate ligament reconstruction (AACLR) produces pain of moderate intensity and provides a useful setting for examining gender-related differences in pain and function. METHODS: This study was a retrospective review of prospectively gathered data collected for a continuous quality improvement program and involved all patients who underwent AACLR at a single outpatient facility since June 1992. Anesthetic, surgical, and perioperative management techniques were standardized. Using a questionnaire, all patients were routinely asked to record pain scores, narcotic consumption, and whether they were able to perform a standardized straight leg-raising maneuver on each of the first 5 postoperative days. RESULTS: A total of 736 patients were enrolled for surgery, 58% of whom completed the entire 5-day questionnaire. Women reported higher pain scores at rest as well as with activity on postoperative day 1 compared with men (P < 0.005). In addition, fewer women were able to perform the straight leg-raising maneuver on postoperative day 1 (P = 0.002) and postoperative day 2 (P = 0.004). There was no difference in the amount of narcotics consumed at any time during the study period. CONCLUSIONS: Women seem to experience greater intensity of pain after AACLR that is associated with a decrease in an intermediate measure of functional outcome. These differences may result from differences in either response to analgesics or neuroprocessing.
