Balancing Knee Implants Using Verasense Sensor During Total Knee Replacement Surgery A Study of Kinematic Alignment in Adults with Osteoarthritis

What this Trial Is About

Researchers are evaluating total knee replacement TKR surgery to address pain and decreased function caused by severe knee arthritis. This study focuses on comparing two surgical approaches the traditional mechanical alignment, which straightens the leg bones, and a newer kinematic alignment that respects the patients natural leg alignment. The study also investigates how using an intraoperative pressure sensor called Verasense to measure soft tissue balance during surgery may affect patient outcomes and satisfaction. Participants will undergo kinematically aligned TKR and be randomly assigned to one of two groups. One group will have their surgery balanced using standard surgeon judgment without access to Verasense data, while the other group will have surgery guided by real-time Verasense pressure sensor feedback to optimize knee balance. The study uses computer-assisted techniques and aims to assess differences in soft tissue balance and the number of ligament releases required during surgery. During the study, participants will be followed for up to two years with assessments including gait analysis to evaluate knee function and patient-reported health outcome questionnaires. Researchers will monitor intraoperative ligament releases and analyze postoperative knee kinematics. The study aims to determine if objective balancing with Verasense improves surgical outcomes compared to the standard subjective method, with safety and function tracked throughout the follow-up period.
