Abstract

Disclosed herein is a balancer algorithm to perform joint balancing calculations to identify target solutions based on surgeon preference. The balancer algorithm can generate a suggested final implant plan from a predetermined range. The balancer algorithm can be used in a knee arthroplasty procedure to generate bone resection depths, bone gaps, implant angulations, required soft tissue release, etc. Input to the balancer algorithm can include preoperative data, intraoperative data, and surgeon preference data.
