Unicompartmental Knee System
Features appropriate proportions and size variations designed based on bone data to fit each individual patient. All nine femoral component sizes can be combined with all six tibial baseplate sizes.
To increase postoperative satisfaction, we pursued a design that allows natural knee motion. The femoral component is designed to extend the posterior condyle and prevent impingement between the bone and the implant during deep flexion. Additionally, the tibial insert has a flat, unconstrained bearing surface.
Using FEA (finite element analysis), the design maintains a large contact area with the tibial insert throughout the entire range of motion, reducing the maximum principal stress generated in the tibial insert. The tibial baseplate has three pegs and no vertical cuts, which is designed to reduce the risk of fractures.
The Initia product line is designed for global markets.
