Cemented vs. Cementless Unicompartmental Knee Arthroplasty

Enrolling by invitation · Not applicable

Conditions studied: Partial Knee Replacement

In brief

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.
