Buried In Cement

1 in 5 partial knee replacements have excess or loose cement floating in the joint.1
Loose cement particles increase polyethylene wear rates by 10X.2
Polyethylene wear debris causes osteolysis.3-6
It’s time to get rid of cement.
Introducing the Engage Partial Knee System.
A truly cementless solution.
