Frequently Asked Questions
Q1: What is the advantage of the 5° Valgus Stem Alignment in the RSK system?
The anatomical stem valgus angle provides a natural femoral fit and is designed to accommodate offset stems, which helps optimize overall component positioning during surgery.
Q2: How does the design of the RSK system preserve bone?
It utilizes a bone-preserving intercondylar design featuring a narrow intercondylar box of ≤22mm, which maximizes bone conservation in the distal femur.
Q3: What level of stability does the Dual Constraint System offer?
The system provides a 0.5° controlled internal/external rotation and 1° varus/valgus constraint tolerance. Its non-hinged constrained bearing maintains essential joint stability in ligament-deficient clinical scenarios.
Q4: How does the Double Locking Mechanism secure the implant?
It integrates a locking screw alongside an advanced locking mechanism designed to reduce backside micromotion to the lowest possible level.
Q5: What are the functions of the Tibial Augment and Tibial Cone?
The Tibial Augment reestablishes joint line alignment and reduces the extension gap with a VS wedge design that minimizes shear forces. The Tibial Cone features a stepped geometry for compressive bone loading to preserve native joint line position and eliminate bone graft requirements.
Q6: What materials are used for the RSK instrumentation components?
The RSK Femoral Condyle and Tibial Tray are manufactured from CoCrMo (Cobalt-Chromium-Molybdenum), while the Tibial Bearing is made of high-durability German UHMWPE (Ultra-High-Molecular-Weight Polyethylene).
