Cemented vs. Cementless Unicompartmental Knee Arthroplasty
Sponsor: Anderson Orthopaedic Research Institute
Summary
The primary study objective is to evaluate a cementless partial knee system that has a modular 3-D printed porous metal tibial component and a cemented partial knee system. The hypothesis is that at minimum 2-year follow-up, fixed bearing medial partial knee replacements using cementless and cemented fixation will demonstrate no differences in clinical outcome.

Cementless fixation
Three dimensional printed porous metal, a biomaterial with morphological and mechanical properties that resemble those of native trabecular bone, is now being used for fixation of the tibial component in unicondylar knee arthroplasty. This can reliably achieve osseointegration into the tibia and could lead to a lower risk of aseptic loosening which is the leading cause of revision in partial knee replacements.
