Abstract

A robotic system has been developed for Minimally Invasive Surgery (MIS) in Total Knee Arthroplasty (TKA). In MIS TKA, it is imperative to achieve high accuracy of bone cutting and short skin incision. However, MIS TKA has a challenging issue as to the tool insertion into the small incision area. Moreover, an inappropriate incision causes inability of bone cutting or interference between tool and skin. Therefore, tool path generation method was developed based on the optimized incision placement. The experiments with model and swine legs showed that we could successfully implement the operation within 80 mm incision in clinical use.
