The Role of Computer Navigation in Optimizing Total Knee Arthroplasty Performance

Although total knee arthroplasty is regarded as having good long-term survival, a significant percentage of patients are dissatisfied. Malalignment and poor soft tissue balancing are significant factors in increased polyethylene wear and early failure. We discuss the role of computer-assisted surgery in improving alignment, its possible effect on tibial insert contact pressures and its use in dynamic soft tissue balancing of the knee. Computer-assisted surgery produces accurate bone resections and better soft tissue balancing, which will ultimately optimize results in knee arthroplasty.
