LimaCorporate’s Physica system is a primary total knee system based on three different configurations: The Kinematic Retaining (KR), the Posterior Stabilized (PS) and the Cruciate Retaining (CR).
The Physica PS is characterized by an innovative 3° asymmetric cam, resulting in a central stress distribution during the whole ROM. This reduces bearing wear and reproduces better kinematics, increasing the jump distance. The femoral cam and the tibial post of the Physica PS increases the poly resistance and reduces the risk of tibial insert dislocation from baseplate during the cam/post engagement.
LimaCorporate’s Physica system provides 10 femoral and tibial sizes for all the three configurations. Matching ±2 between the femoral component and the tibial insert is possible and vice versa. This means that our total knee system has five possible combinations.
A common tibial plate for all three options allows intraoperative versatility.
The Physica system femoral components also incorporates a thin flange and a deep large trochlear groove. This reduces anterior knee pain and reproduces the physiological patellar tracking.
The multi-radius design of Phyica PS, with gradually reducing radius for femoral component (J-Curve), maintains the correct ligament balancing during the entire ROM.
