Physica ZUK
With proven clinical heritage, optimizing function and precise execution, Physica ZUK is the best performing UKA at 5, 10 & 15 years. Physica ZUK benefits from an unchanged design for more than 20 years.
Proven Clinical Heritage
Best performing UKA at 5, 10 & 15yrs (1) with its unchanged design for more than 15 years is supporting repeatable and reproducible results (2, 3, 4, 5, 6).
Optimizing Function
The fixed bearing design is reducing post-operative complications of bearing dislocation (7), improving functional outcomes and FJS (8).
Precision Execution
Simple and easy-to-use instrument set for fine-tuning preparation and repeatable and reproducible surgical technique. Same implant for Medial and Lateral UKA.
About
Physica ZUK offers an unchanged design for more than 20 years
Fixed bearing design with metal tibial baseplate + liner (available in UHMWPE or LimaVit) & all-poly tibia options, universal tibial and femoral components for lateral and medial UKA and universal tibial/femoral compatibility.
The design allows for native knee kinematics, reduces risk of overstuffing and reduces post-operative complication of bearing dislocation.
Physica ZUK has a PMMA coating on femoral and metal tibial components for advanced cement adhesion.
