Product Overview

The Femoral Component (PSA) is a key component of the XU-Knee PSA Revision System, designed for revision total knee arthroplasty requiring enhanced stability and flexible reconstruction.

The component is manufactured from cobalt-chromium-molybdenum alloy and adopts a modular design concept, allowing integration with femoral augments, femoral screws, extension stems, and offset adapters to accommodate different bone defect conditions and reconstruction requirements.

The optimized posterior-stabilized design provides improved femorotibial stability through early post-cam engagement and enhanced constraint geometry.

Product Features & Clinical Benefits

Modular Reconstruction Design

• Compatible with femoral augments, extension stems, offset adapters, and fixation screws.
• Provides flexible solutions for different revision scenarios.
• Supports individualized reconstruction according to bone loss conditions.

High-Strength Co-Cr-Mo Alloy Structure

• Manufactured from cobalt-chromium-molybdenum alloy.
• Provides excellent mechanical strength and wear resistance.
• Supports reliable performance under revision knee loading conditions.

Enhanced Posterior-Stabilized Design

Early Post-Cam Engagement

• Post-cam engagement begins at approximately 40° flexion.
• Improves femorotibial stability during knee motion.
• Provides enhanced control throughout the range of motion.

Increased Jumping Distance Design

• Jumping distance reaches 21.4 mm.
• Helps reduce the risk of postoperative dislocation.
• Enhances overall implant stability during deep flexion.

Curve-on-Curve Articulation Design

• Optimized curvature design with R30 mm.
• Provides more restrictive femoral intercondylar stability.
• Supports controlled knee movement and improved constraint.

Optimized Rotational Stability

• Designed to provide controlled varus/valgus and rotational stability.
• Supports up to ±1.4° varus/valgus lift-off limitation.
• Allows up to ±3.7° internal/external rotation.
