Product Details
China's Premier Suppliers of Cementless Unicompartmental Knee System - Advanced Surgical Technology from Factory
Special Description
Immediate Stability
The column reinforcement design, with precise size control, ensures immediate stability.
Test verification shows that after implantation, the femoral condyle prosthesis exhibits high resistance to pull-out, ensuring excellent initial stability.
The optimized dual-coating process results in a surface roughness Ra value 1.7 times higher than the standard requirement, enhancing immediate stability.
The keel is widened, and the processing groove is narrowed, with tool height alignment to ensure immediate stability.
Prosthesis stress distribution
Excellent Fatigue Resistance
10 million cycles of load testing verifying durability
Through 10 million cycles of fatigue testing on the coating covering the metal substrate and the prosthesis, it has been verified that under the premise of excellent bonding strength between the dual coating and the substrate, the prosthesis can achieve a very high fatigue limit stress.
Animal study Histological observation after sample implantation
Excellent Bone Growth Effect
- New bone is visible at the pore opening.
- The material closely conforms to the new bone.
- No fibrous capsule or inflammatory cells are seen at the material/bone interface.
Long-term Stability
Optimized product design and precise surgical instrument design achieve full contact between the dual-coating and bone tissue, providing a better foundation for bone growth.

Frequently Asked Questions
What structural designs of the AUSK Cementless Uni-knee ensure immediate stability?
Immediate stability is achieved through a column reinforcement design with precise size control, a widened keel, a narrowed processing groove, tool height alignment, and an optimized dual-coating process that increases surface roughness Ra value to 1.7 times higher than the standard requirement.
How has the fatigue resistance of the prosthesis been verified?
The fatigue resistance has been verified through 10 million cycles of load testing on both the prosthesis and the coating covering the metal substrate, proving that the prosthesis achieves a very high fatigue limit stress while maintaining excellent coating-to-substrate bonding strength.
What observations were made in the histological animal study after implantation?
The animal study demonstrated excellent bone growth effects: new bone growth was visible at the pore opening, the material conformed closely to the new bone, and there was no presence of a fibrous capsule or inflammatory cells at the material/bone interface.
What materials are used in the components of the AUSK Cementless Unicompartmental Knee System?
The AUSK Femoral Condyle and Tibial Tray are manufactured from CoCrMo (Cobalt-Chromium-Molybdenum), while the Tibial Bearing is made from Germany Highly Crosslinked PE (Polyethylene).
How does the design support long-term stability and bone growth?
By optimizing the product design and using precise surgical instruments, the system ensures full contact between the dual-coating and the bone tissue. This good conformability provides a better foundation for natural bone growth and long-term implant stability.
What sizes and specifications are available for the Tibial Bearing?
The Tibial Bearing comes in sizes 1#, 2#, 3#, and 4#, with thickness options ranging from 3mm to 7mm, available in both Right (R) and Left (L) configurations.
