Product Overview

The U2 PF+ Knee System is a comprehensive, advanced Press-fit Total Knee Replacement (TKR) system designed to meet the needs of patients, surgeons, hospital and surgery centers globally.

The system offers a three-dimensional coating designed for optimal pore size and porosity, a conforming femoral shape in 13 sizes with 2 mm A/P and M/L sizing increments, a unique box design and a consistent intercondylar box width, a full range of tibial articulating surface and multiple material options, and a modern tibial baseplate design for initial fixation and stability.

UNITED Asymmetric Sintering Coating Technology

UNITED Asymmetric Sintering Coating (ASC) Technology creates a unique three-dimensional structural lattice of irregularly shaped shards to increase the average pore size more than traditional spherical beads. The irregularly shaped interconnecting pores maximize coverage on bone contacting surfaces to promote optimal bone growth and fixation to the implant.

ASC Technology is available with U2 PF+ Knee System to provide an excellent balance among material strength, pore sizes, and porosity for a reproducible press-fit fixation in total knee arthroplasty.
