RSK PS High Flexion Hybrid Revision Knee System
Product Details
● Optimized Femoral Design
8 Sizes with Built-In 5° Valgus Angle
Ensures optimal bone coverage and adaptability.
Enlarged Lateral Posterior Condyle & Ultra-Mirror Polishing
Increases joint contact, reduces wear, and minimizes debris.
● Defect Management
Extension Rod and Block Connectivity
Facilitates effective management of femoral bone defects during surgery.
● Efficient Tibial Bearing Insertion
High Flexion Support
Compatible with all femoral condyle models and supports up to 145° flexion.
Easy Posterior Insertion
Ensures quick, accurate installation with the tibial tray and a widened, heightened post with a hook reduce dislocation risk.
● Tibial Tray Design
Advanced Locking Mechanism & Polished Surface
Minimizes backside micromotion and wear while accepting augments and stem extensions for complex cases.
1:1 Tibiofemoral Surface Contact & Narrowed Keel
Maximizes load distribution and conserves bone stock.
Special Description
5° Valgus Stem Alignment
• Anatomical stem valgus angle for natural femoral fit
• Accommodates offset stems to optimize component positioning
Bone-Preserving Intercondylar Design
• ≤22mm narrow intercondylar box
• Maximizes bone conservation in distal femur
Dual Constraint System
• 0.5° controlled internal/external rotation
• 1° varus/valgus constraint tolerance
• Non-hinged constrained bearing maintains stability in ligament-deficient clinical scenarios
Double Locking Mechanism
NO.1 Locking Screw
NO.2 Advanced locking mechanism reduces backside micromotion to the lowest level
Tibial Augment
• Reestablish joint line alignment
• Reduce extension gap
• VS wedge design minimizes shear forces, improves joint stability
Tibial Cone
- Stepped geometry for compressive bone loading
- Preserves native joint line position
- Eliminates bone graft requirements
