Utilization of a 3D Printed Mechanical Balancer During Total Knee Arthroplasty (TKA)

The 3D printed mechanical balancer is a surgeon-controlled handheld intraoperative tool used that provides a quantifiable measurement of force differences on the medial and lateral sides to guide achievement of a balanced knee. It will be used at one timepoint during scheduled TKA surgery while the patient is under anesthesia. Readings will be taken at 0, 45, and 90 degrees of flexion.
