Physica KR

By understanding the Science of Movement

the Physica system design aims to restore the native knee kinematics and optimize function to enable the patient to once more experience the joy of movement and improve patient satisfaction following TKA.

Benefits

01

Restore Kinematic

Physica system is designed to restore the native knee movement by focusing on a kinematic respecting design.

02

Optimizing Function

The design aims to optimize the function of the knee to improve the outcomes following TKA.

03

Precision Execution

The Physica system ensures excellent functional outcomes for all patients as the surgical procedure is easy to follow and the instruments are accurate, easy to use and lead to repeatable and reproducible results. Available for all the configurations (Physica KR, CR, LMC and PS).

About

The Physica system is a primary total knee system. It features different configurations: The Kinematic Retaining (KR), the Posterior Stabilized (PS), The Lima Medial Congruent (LMC) and the Cruciate Retaining (CR).

The Physica KR aims to replicate the natural knee kinematics during the entire ROM. The unique shapes of the femoral component and tibial liner guide the movement of the knee and ensure correct posterior displacement of Tibio-Femoral contact point.
The Patented unique asymmetric tibial liner and femoral component design allow the Mid-flexion stability due to maintaining the same rectangular joint space and therefore collateral ligament isometry throughout complete range of motion.
A multi-radius design with gradually reducing radius for femoral component (J-Curve), maintains the correct ligament balancing during the entire ROM.

Sizing
& Options

LimaCorporate’s Physica system provides 10 femoral and tibial sizes for all four 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 cemented or uncemented tibial plate for all the femoral configuration allows intraoperative versatility.

Physica KR femoral component options available: cemented and cementles

Physica KR liner is available in 6 thicknesses and made of UHMWPE or LimaVit.
