Abstract
A method of evaluating a knee joint including a femur, a tibia, and ligaments, includes: inserting into the joint a tensioner-balancer; moving the joint while using the tensioner-balancer to maintain predetermined distraction force or distraction height, and collecting height and force data; deriving ligament displacement data and load data from the height and distraction data; processing the data into a digital model of the joint, including a characterization curve for a plurality of flexion angles; importing into the model implant geometry having femoral and tibial components, each having a back surface; updating the model with a location of femoral and tibial cuts, positioned such that when the components are placed in the joint with their back surfaces against the respective cuts, the implant will position the joint to function in a selected portion of the curve; and storing the model.
