Description

The PTG U2 PSA™ is a fixed-bearing femoral revision prosthesis with a fixed PS constrained insert.

The PSA femur has a multi-radius design with a “patella friendly” trochlear groove that promotes flexion and stability.

The femoral component and the tibial baseplate require the insertion of pins and enable the use of wedges.

The U2 Knee™ System provides the option of mixing a 1st line treatment CR or PS femur with a PSA tibia.
