Frequently Asked Questions (FAQ)
Q:
What are the benefits of the 5° Valgus Stem Alignment in the RSK system?
The 5° Valgus Stem Alignment features an anatomical stem valgus angle that ensures a natural femoral fit. Additionally, it accommodates offset stems to optimize component positioning during surgery.
Q:
How does the RSK system promote bone preservation?
It features a bone-preserving intercondylar design with a narrow intercondylar box of ≤22mm, which maximizes bone conservation in the distal femur.
Q:
What makes the Dual Constraint System stable in ligament-deficient scenarios?
The system provides a 0.5° controlled internal/external rotation and a 1° varus/valgus constraint tolerance. Its non-hinged constrained bearing maintains exceptional stability even in ligament-deficient clinical scenarios.
Q:
How does the Double Locking Mechanism prevent micromotion?
The system utilizes a dual configuration featuring a Locking Screw (NO.1) and an advanced locking mechanism (NO.2) that reduces backside micromotion to the lowest possible level.
Q:
What functions do the Tibial Augment and Tibial Cone perform?
The Tibial Augment reestablishes joint line alignment, reduces extension gaps, and features a VS wedge design to minimize shear forces. The Tibial Cone uses a stepped geometry for compressive bone loading, preserving the native joint line and eliminating the need for bone grafts.
Q:
What materials are used in the RSK instrumentation?
The RSK™ Femoral Condyle and Tibial Tray are constructed from highly durable CoCrMo (Cobalt-Chromium-Molybdenum) alloy. The RSK™ Tibial Bearing is made from premium Germany UHMWPE (Ultra-High-Molecular-Weight Polyethylene).
