Custom unicompartmental knee arthroplasty

Abstract

Customization of a unicompartmental knee arthroplasty (UKA) implant is a new surgical philosophy aiming at reproducing the patient’s anatomy and joint morphology while minimizing modifications in the biomechanics of the knee joint during reconstruction. Combining the advantages of single-use patient-specific instrumentation and custom implants led to the development of a unique UKA implant system. Custom UKA would offer clinician the opportunity to accurately restore each patient’s femoral and tibial morphology while providing additive material to compensate for cartilage loss. Using this particular technique, better restoration of the natural knee kinematic is achieved through personalization of the implants.
