The Physica KR is a primary total knee system. It features three different configurations: The Kinematic Retaining (KR), the Posterior Stabilized (PS), and the Cruciate Retaining (CR).
The Physica KR aims to replicate the natural knee kinematics during the entire ROM. This occurs thanks to the interaction of asymmetrical femoral condyles and bearing surfaces. The tibial KR liner’s design includes anterior and posterior lips that compensate the loss of the ACL and menisci. The Physica KR surfaces provide rotational stability as well as inducing Roll-Back.
LimaCorporate’s Physica system provides 10 femoral and tibial sizes for all three configurations. It is possible to match ±2 between the femoral component and the tibial insert. 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 KR, with gradually reducing radius for femoral component (J-Curve), maintains the correct ligament balancing during the entire ROM.
