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.
