CPIS: Continuous Perineural Infusion Study

For patients undergoing a total knee replacement, pain is a major concern. Our goal is to provide patients with the best form of postoperative pain control. This research study is a double-blind, prospective, randomized trial to assess an infusion system, which has been shown to have superior pain control with other operations. Our current study examines the effectiveness of this infusion device at relieving pain after a TKR. Pain, nausea, and satisfaction are evaluated via the Visual Analog Scale (VAS) pre- and post-operatively. Functional outcomes are assessed via the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and the Knee Society Score (KSS), pre- and post-operatively.

All patients in the study receive the standard of care for pain control, in addition to the infusion device. We hope that through the trial, we can determine if this infusion device will provide better postoperative pain relief and improve patient satisfaction following a TKR.
