Product Details
China's Premier Cementless Unicompartmental Knee System | Top Suppliers & Factory
Special Description
- 01 The column reinforcement design, with precise size control, ensures immediate stability.
- 02 Test verification shows that after implantation, the femoral condyle prosthesis exhibits high resistance to pull-out, ensuring excellent initial stability.
- 03 The optimized dual-coating process results in a surface roughness Ra value 1.7 times higher than the standard requirement, enhancing immediate stability.
- 04 The keel is widened, and the processing groove is narrowed, with tool height alignment to ensure immediate stability.
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.
- 02 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.
- 01 Good conformability: Optimized product design and precise surgical instrument design, achieving full contact between the dual-coating and bone tissue, providing a better foundation for bone growth.

Technology Education
Frequently Asked Questions
What features of the AUSK Cementless Uni-knee design contribute to immediate stability?
Immediate stability is achieved through a column reinforcement design with precise size control, a widened keel, a narrowed processing groove with tool height alignment, and a femoral condyle prosthesis design showing high resistance to pull-out after implantation.
How does the dual-coating process benefit the implant?
The optimized dual-coating process increases the surface roughness Ra value to 1.7 times higher than standard requirements. This enhancement significantly improves the implant's initial stability and creates a superior interface for bone integration.
What are the fatigue testing outcomes for this knee system?
The prosthesis successfully completed 10 million cycles of fatigue testing. The results verified excellent bonding strength between the dual coating and the metal substrate, showing that the device can withstand high fatigue limit stress.
What did the histological observation in the animal study demonstrate?
The histological evaluation demonstrated excellent bone growth. New bone formation was clearly visible at the pore openings, conforming closely to the material. Additionally, there was no detection of fibrous capsules or inflammatory cells at the material-bone interface.
What materials are used in the AUSK Cementless Unicompartmental Knee System components?
The AUSK Femoral Condyle and Tibial Tray are fabricated from Cobalt-Chromium-Molybdenum (CoCrMo) alloy. The mobile Tibial Bearing is made from Germany Highly Crosslinked Polyethylene (PE) to ensure high durability and wear resistance.
How does the system support long-term implant stability?
Long-term stability is facilitated by optimized product design combined with high-precision surgical instruments. This system ensures full contact between the dual-coating and the host bone tissue, providing an optimal foundation for ongoing bone growth.
