The system includes three different types of total knee implants.
- “Physica KR is a patented kinematic and posterior cruciate ligament (PCL) retaining design able to induce natural knee kinematics without the use of a constraint mechanism.” The KR “is available for the European market and cleared by the FDA in the U.S.”
- “Physica PS is the posterior stabilised solution (PCL sacrificing) with an asymmetric cam which allows an optimized knee kinematic profile and an enhanced load transmission through the tibial post during the entire flexion and extension cycle.”
- The system” also includes a CR version or cruciate retaining implant which is PCL retaining and designed to conserve bone to improve load transfer and enable more anatomical patellar tracking. Both the Physica PS and CR are available for the European markets.”
