U2 MB Knee | United Orthopedic Corporation | Hip and Knee Implants


Product Overview

The U2 MB (Mobile Bearing) Knee is a rotating tibial platform design intended to facilitate prosthetic alignment and lower shear force on the bone-implant interface.

The U2 MB Knee is compatible with both U2 fixed bearing Posterior Stabilized (PS) and Cruciate Retaining (CR) femoral components.

Product Features

Slide The extended patella groove is designed with increased contact area between the patella and femoral implants for optimal patella tracking. PS and CR femoral components are offered in 2 mm A/P and M/L increments to provide a comprehensive femoral sizing solution. Augmentable baseplate design allows for augments and 20, 45, 70, 95 mm extension stems to address tibial bone defects. A highly mirror-polished tibial baseplate surface underneath the tibial insert is designed to reduce backside wear and allow the insert to rotate in an internal-external direction.
