Short-Term Effects of Early Postoperative Celecoxib Administration for Pain, Sleep Quality, and Range of Motion After Total Knee Arthroplasty: A Randomized Controlled Trial
Abstract
BACKGROUND
We hypothesized that early postoperative administration of celecoxib would reduce pain scores and improve sleep quality and active range of motion after total knee arthroplasty (TKA) under general anesthesia.
METHODS
Patients in the celecoxib group received 400 mg of celecoxib 2 hours after TKA, followed 6 hours later by 200 mg of celecoxib. Patients in the control group received 400 mg of celecoxib the second day after surgery. Patients in both group had access to patient-controlled analgesia fentanyl. The primary outcome measure was the patient-reported visual analog scale (VAS) pain score the second day after TKA. The secondary outcome measure was sleep quality (days 1, 2, and 7 postoperatively). Active knee joint range of motion was assessed on days 2 and 7 postoperatively, and VAS pain scores were evaluated on postoperative days 1 to 7. Total fentanyl consumption was also assessed.
RESULTS
Compared to the control group, the celecoxib group had significantly lower median VAS pain scores on postoperative days 1 and 2, significantly less nocturnal awakening (in minutes) and frequency of body motion, and better sleep efficacy on postoperative day 1. The celecoxib group also had a significantly better median flexion angle (°) on postoperative days 2 and 7, and lower cumulative fentanyl consumption.
CONCLUSION
Early administration of celecoxib after TKA was associated with significantly reduced early VAS pain scores and improved sleep quality and active knee…
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.
