Total Knee Replacement Surgery

Total knee replacements are among the most common and painful orthopedic procedures performed worldwide, often requiring intensive analgesia to support early ambulation and recovery. Despite widespread use of multimodal regimens, many patients still rely on opioids, which can cause sedation, nausea, constipation, and long-term dependency. Evaluating suzetrigine in this high-need population may improve recovery trajectories, reduce opioid consumption, and support enhanced recovery protocols. Given the growing surgical volume and the emphasis on opioid-sparing strategies, rigorous investigation of suzetrigine's efficacy in total knee replacement is of high clinical value. In this confirmatory (phase III) trial, patients undergoing primary total knee replacement will be randomized to receive either suzetrigine or placebo for 2 weeks (14 days), with the loading dose administered prior to surgery. The primary outcome is cumulative 48-hour opioid consumption in oral morphine equivalents starting from entry into the post-anesthesia care unit (PACU).

This is a prospective, randomized study. The purpose of this study is to evaluate if the addition of Suzetrigine, a new pain medication, to well established peri-operative pain regimen used for total knee replacement surgery will effect pain control. 1. Does Suzetrigine given pre-operatively decrease the total opioid consumed after total knee replacement surgery? 2. Dose Suzetrigine given pre-operatively decrease the visual analog pain scale pain scores after total knee replacement surgery? Study participants will be randomly assigned to receive either Suzetrigine medication or placebo medication.

The overall aims of this prospective, randomised, single-blinded controlled trial are to compare functional, radiological and clinical outcomes in Mako robotic-arm assisted cementless Total Knee Arthroplasty (TKA) versus Mako robotic-arm assisted cemented TKA.

The aim of this study is to compare the Competency of coupling of IPACK Block with Adductor Canal Block versus Adductor Canal Block Alone on Postoperative Pain after total knee replacement as well as Functional Recovery and Inflammatory Response and range of motion postoperatively.

This study compares the accuracy of two different techniques in placing a total knee replacement. In one technique, accurate instrument placement is facilitated by a robot, and in the other technique, augmented reality is used for correct instrument placement. Both surgical techniques are already commonly used. During both the robotic technique and the augmented reality technique, the additional information (angles - axes) obtained during the operation is used to optimize the placement of the various prosthesis components. Patients that were recently diagnosed with advanced osteoarthritis of the knee can participate in this study. This means that the cartilage of the knee is affected by wear and tear. This causes pain, stiffness and swelling resulting in reduced mobility. When non-operative treatments are insufficient in treating the osteoarthritis, surgery is proposed wherein a knee arthroplasty is performed. The goal of this study is to further optimize and personalize patient care. Additionally, the aim of the study is to investigate whether both techniques are equivalent in optimally placing the prosthesis and whether both techniques lead to comparable results.

The research will be conducted to determine the effect of progressive relaxation exercises on the anxiety level of patients who have had total knee replacement surgery.
