Perioperative celecoxib administration for pain management after total knee arthroplasty – A randomized, controlled study
Abstract
BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are recommended for multimodal postoperative pain management. We evaluated opioid-sparing effects and rehabilitative results after perioperative celecoxib administration for total knee arthroplasty. METHODS: This was a prospective, randomized, observer-blind control study. Eighty patients that underwent total knee arthroplasty were randomized into two groups of 40 each. The study group received a single 400 mg dose of celecoxib, one hour before surgery, and 200 mg of celecoxib every 12 hours for five days, along with patient-controlled analgesic (PCA) morphine. The control group received only PCA morphine for postoperative pain management. Visual analog scale (VAS) pain scores, active range of motion (ROM), total opioid use and postoperative nausea/vomiting were analyzed. RESULTS: Groups were comparable for age, pre-operative ROM, operation duration and intraoperative blood loss. Resting VAS pain scores improved significantly in the celecoxib group, compared with controls, at 48 hrs (2.13 +/- 1.68 vs. 3.43 +/- 1.50, p = 0.03) and 72 hrs (1.78 +/- 1.66 vs. 3.17 +/- 2.01, p = 0.02) after surgery. Active ROM also increased significantly in the patients that received celecoxib, especially in the first 72 hrs [40.8 degrees +/- 17.3 degrees vs. 25.8 degrees +/- 11.5 degrees , p = 0.01 (day 1); 60.7 degrees +/- 18.1 degrees vs. 45.0 degrees +/- 17.3 degrees , p = 0.004 (day 2); 77.7 degrees +/- 15.1 degrees vs. 64.3 degrees…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
