Tibial Bearing Primary TKA System
High Flexion Total Knee Artificial Replacement
🔹 Femoral Condylar Features
- High flexion design for enhanced mobility.
- Optimized patellofemoral articular design.
- Almost custom-made component size with 2mm increments in A/P.
- Proportional posterior condyles allow for greater contact area in deep flexion.
- Mirror polished surface reduces wear and debris post-operatively.
- Soften intercondylar notch reduces post wear in flexion.
- Cam extension provides increased resistance to dislocation in deep flexion.
- All femoral condyle match with tibial tray perfectly.
🔹 Tibial Tray & Bearing
Tibial Tray:
- Narrowed cruciate fins preserve more bone stock.
- High polished surface minimizes back wear of bearing.
- Precision sizing close to customization.
Tibial Bearing:
- Designed specifically for high flexion requirements.
- Allows for proper axial rotation and hyperextension of the knee.
- Interchangeable for femoral components of all sizes.
- 1:1 coronal congruency increases contact area in high flexion.
- Rounded post geometry minimizes rotational forces.
Design Advantages
1. Rounded Sagittal Profile
Allows for a greater range of motion and is more forgiving to the retinaculum by preventing over-tensioning of soft tissues.
Anatomic (Green) vs. Swept-back Sagittal Profile (Gray)
2. Deeper Swept-back Trochlear Groove
Designed to resist patella crepitus and clunk, ensuring superior patellar performance during movement.
3. Extended Trochlear Groove
Supports the patella in deep flexion and provides additional support for the quadriceps tendon between 105-120 degrees.
4. Wider Proximal Trochlear Groove
Balances patellar capture during flexion with reduced constraint in extension. Provides a 6.5-degree valgus angulation to reduce shear stresses.

Frequently Asked Questions
What is the standard delivery time for orders?
Generally, it takes 8 to 15 days after receiving your advance payment. The specific timeframe depends on the items and the quantity of your order.
Do you conduct quality testing before shipping?
Yes, we perform 100% rigorous testing on all goods before delivery to ensure the highest medical standards.
What materials are used in the TKA components?
The products are manufactured using medical-grade CoCrMo (Cobalt-Chromium-Molybdenum) and high-quality Polyethylene (PE).
What are the available payment methods?
We accept various payment methods including TT (Telegraphic Transfer), L/C (Letter of Credit), and Western Union.
Are the femoral and tibial components customizable?
Yes, we provide almost custom-made sizes with small increments (e.g., 2mm in A/P) to ensure a perfect fit for diverse patient anatomies.
What is the maximum flexion angle for this knee system?
This high-flexion system is designed to support up to 145° of flexion, allowing patients a greater range of motion for daily activities.
