Implant Choices for Unicompartmental Knee Arthroplasty

Unicompartmental knee arthroplasty (UKA) design has gone through several iterations since its inception to include cemented versus cementless fixation, modular metal-backed versus all-polyethylene tibial components, and mobile-bearing versus fixed-bearing designs. In direct comparison studies of modern UKA designs, cementless fixation may offer a slight advantage in implant survivorship in addition to shorter operative times. The literature has not provided a consensus on the superiority of all-polyethylene versus metal-backed tibial components or mobile-bearing versus fixed-bearing implants, as each of these design features has inherent advantages and disadvantages.
