Abstract
Background: Patients undergoing total knee arthroplasty usually receive a multimodal analgesic regimen including peripheral nerve blockade, but may still experience significant pain. This study examined whether preoperative gabapentin decreases acute postoperative pain and opioid consumption in this setting. Methods: Retrospective chart review of single institution, hospital-based orthopaedic practice. Consecutive patients undergoing unilateral elective primary knee arthroplasty were evaluated for perioperative gabapentin use. Sixty-one consecutive patients received gabapentin; for each, an age- and gender-matched control was identified. Results: Patients in both groups demonstrated similar demographics, all received lumbar plexus blockade. Catheters were removed on postoperative day 2 (95%). There were no differences in postoperative pain scores or opioid use between groups. Overall, median verbal pain scores (IQR) were 0(1), 0(3), 1(3) and 3(3) in the post-anaesthesia care unit and postoperative days 0, 1 and 2, respectively. Postoperative consumption of other analgesics was not different across groups. Patients in the gabapentin group received a single-injection sciatic nerve block less often than patients in the control group (77% vs. 94%, respectively; p < 0.05). Conclusions: Patients undergoing unilateral total knee arthroplasty experience low pain scores utilizing a multimodal analgesic regimen including continuous lumbar plexus blockade independent of gabapentin use.
