Knee Tensioner-Balancer Method Patent B2
Summary
The USPTO granted Patent US12599377B2 to Dynamic Balancer Systems LLC on April 14, 2026. The patent covers a knee tensioner-balancer method using force sensors to evaluate human knee joints and generate digital geometric models. The invention tracks medial and lateral condyle contact points during knee flexion across a range of angles.
What changed
The USPTO issued Patent US12599377B2 for a knee tensioner-balancer device and method. The invention inserts a tensioner-balancer with force sensors into a knee joint, collects force data during range-of-motion movement, and processes the data to create a digital geometric model including medial and lateral splines representing condyle contact loci.
Medical device manufacturers and healthcare technology developers should monitor this patent for potential licensing opportunities or design considerations. The patent may affect competitive positioning in knee assessment and surgical balancing device markets.

Abstract
A method of evaluating a human knee joint including a femur bone, a tibia bone, and ligaments. The method includes: inserting into the joint a tensioner-balancer that includes at least one force sensor; providing an electronic receiving device; moving the knee joint through at least a portion of its range of motion; using the electronic receiving device to collect data from the at least one force sensor; processing the collected force data to produce a digital geometric model of the knee joint, wherein the data includes: a medial spline representing a locus of points of contact of a medial condyle of the femur F with the tensioner-balancer, over a range of knee flexion angles; and a lateral spline representing the locus of points of contact of the femur F with the tensioner-balancer, over a range of knee flexion angles; and storing the digital geometric model for further use.
