Abstract

Several factors are involved in the failure of unicompartmental knee arthroplasty (UKA), including the patient’s age, anterior cruciate ligament deficiency, and alignment. To address these failures, a computer-aided navigation system that consistently provides accurate measurements was developed to reduce the errors committed with conventional UKA. The undercorrection with a minor varus alignment produced by this system provides appropriate outcomes and longevity for UKAs. The computer navigation system thus offered a procedure to attain optimal alignment. Although a learning period is required for computer-assisted surgery, the computer-assisted UKA produced comparable range of motion and WOMAC and Oxford scores with fixed-bearing UKA implantation.
