Product Overview

The Femoral Component (CR) is designed for primary total knee arthroplasty requiring posterior cruciate ligament preservation.

Based on Chinese-specific anatomical characteristics, the femoral component incorporates optimized AP/ML proportional design and expanded sizing options to improve implant fit and reduce anatomical mismatch.

The component features a bone-preserving intercondylar design, optimized trochlear geometry, and high-flexion capability to support natural knee movement and long-term functional performance.

Product Features & Clinical Benefits

Chinese-Specific Anatomical Sizing Design

• AP/ML ratio optimized according to Chinese patient anatomy.

• Expanded size range with half-size options for improved femoral coverage.

• Reduces overhang and improves component fit.

Bone Preservation Design

• Optimized intercondylar notch design with increased fillet radius.

• Minimizes bone resection and reduces the risk of intercondylar fracture.

• Requires only 9 mm distal and posterior condyle resection.

Optimized Femoral Articulation Design

• Curve-on-curve articulation design optimizes contact mechanics.

• Improved femoral condyle and tibial insert radius matching reduces contact stress.

• Supports reduced polyethylene wear.

Safe High-Flexion Performance

• Optimized posterior condyle geometry supports high-flexion activities.

• Rear-edge bevel design improves range of motion.

• Supports knee flexion up to 155°.

Enhanced Patellar Tracking Design

• Extended trochlear groove increases patellofemoral contact area.

• Optimized patellar tracking helps improve anterior knee mechanics.

• Supports smoother patellar movement during flexion and extension.
