Description

The PTG U2 CMA™ is a fixed-bearing cruciate-retaining femoral prosthesis that provides the option of adding a short pin and tibial wedges.

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

The CMA tibial baseplate offers the intraoperative choice of a cruciate-retaining or ultra-congruent insert.
