With time tested implant design and award-winning instrument solutions, the U2 Knee offers a complete TKR platform.

Product Features

Slide Consistent condylar curvature and standard intercondylar box width (in PS knee) allows full interchangeability between femoral and tibial components. Various constraint and material options are available with posterior slope built into tibial inserts. E-XPE APT CR PS UC XPE UHMWPE 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. A universal baseplate design allows for augments and a 30 mm extension stem to address tibial bone defects. Cemented tibial baseplate Augmentable tibial baseplate The curved anterior post and cam is designed to reduce potential for impingement, component failure and poly wear.

The U2 Knee System provides a full range of interchangeable design options with multiple insert choices with fixed and Mobile Bearing options.

For patients with severe bone deficiency, the U2 PSA Knee Revision System can be used with augments and extension stem options to manage soft tissue and bone defects.

Innovative and Award Winning Instrumentation

The innovation of the U2 Knee System – AiO & MDT was awarded the Bronze Winner at the 21st Annual Medical Design Excellence Awards (MDEA).

AiO (All-In-One) Femoral Block
