Unity Knee PS Insert Posterior-stabilized total knee prosthesis

Intended purpose

The Unity Total Knee System is intended for use in total knee arthroplasty in skeletally mature patients, to provide increased mobility and reduce pain by replacing the damaged knee joint articulation where there is evidence of suffiecent sound bone to seat and support the components.

Functional description

The Unity Knee™ is a fixed bearing total knee replacement system that consists of a femoral component, tibial insert, tibial tray and all-polyethylene patellar component for use in primary total knee arthroplasty. The Unity Knee™ PS variant is utilized when a total knee replacement is indicated, and the posterior cruciate ligament is non-functioning or absent, resulting in joint instability. The Unity Knee™ is intended for cemented use, single use only.
