Cementless Unicompartmental Knee System - China's Leading Supplier & Factory for Advanced Orthopedic Solutions
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.
Prosthesis stress distribution
10 million cycles of load testing Verifying excellent fatigue resistance: 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
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.

How does the AUSK Cementless Uni-knee achieve immediate stability?
Immediate stability is achieved through a column reinforcement design with precise size control, a widened keel, a narrowed processing groove, and tool height alignment. Tests verify high resistance to pull-out after implantation, ensuring excellent initial stability.
What makes the dual-coating process advantageous?
The optimized dual-coating process results in a surface roughness Ra value that is 1.7 times higher than the standard requirements, which significantly enhances immediate stability and provides an ideal foundation for long-term bone growth.
How is the fatigue resistance of the prosthesis verified?
The prosthesis has undergone 10 million cycles of fatigue testing. Under the premise of excellent bonding strength between the dual coating and the substrate, the prosthesis achieved a very high fatigue limit stress, ensuring long-term structural integrity.
What are the histological findings of this cementless knee system?
Animal studies show excellent bone growth, with new bone visible at the pore opening closely conforming to the material. Crucially, no fibrous capsule or inflammatory cells are observed at the material-to-bone interface.
What materials are used in the AUSK Cementless Uni-knee components?
The Femoral Condyle and Tibial Tray are made of high-quality CoCrMo (Cobalt-Chromium-Molybdenum) alloy. The Tibial Bearing is made of Germany Highly Crosslinked PE (Polyethylene) to optimize durability and wear performance.
