The UC version of the Rolflex TONIC is an evolution of the Rolflex Anatomic which has been in successful clinical use since 2007. It is a UC type of primary Total Knee Prosthesis: ultra-congruent or “Deep Dish” available only with rotating bearing.
The joint stability following sacrifice of the PCL is assured by the anterior and posterior lips of the UHMWPE liner which are higher than for the PS version, yet preserving a high level of mobility and low stress to the implant-to-bone interface.

The tibial baseplates are adapted to the implantation side (asymmetric) as for the femoral condyles.
Available in 10 Right and Left femoral sizes and 9 Right and Left tibial sizes all of which can be mixed-and-matched, the range allows a close fit to all the anatomies.
Nevertheless, the surgical implantation of the Rolflex TONIC UC TKA requires only 3 trays of instruments besides the half-tray of the trial condyles and the optional half-tray of patellar preparation.
