AUSK Cementless Unicompartmental Knee System
Material Selection
Highly adaptable biomaterials balancing wear resistance and biocompatibility.
Core load-bearing components are manufactured from Ti6Al4V titanium alloy and forged CoCr-Mo alloy to meet structural strength requirements under physiological loads. Bone-contact surfaces are coated to enhance osseointegration.
Vitamin-E humeral insert: effectively prolongs implant service life, providing oxidation stability,wear resistance, and mechanical strength.
Fixation Method
● Straight stem with tapered design provides anti-rotation and ensures primary implant stability.
● Proximal roughened stem surface with high friction coefficient ensures reliable initial stability.
● Glenoid baseplate features a modular 6.5 mm central screw with four peripheral screws for initial stability.
● Central peg helps transfer load to the scapula, enhancing fixation and shear resistance.
● Composite coating on both humeral and glenoid sides ensures long-term stability and osseointegration.
● Dual coating of pure titanium and hydroxyapatite (HA) provides excellent bioactivity and osteoconductivity, enhancing long-term implant stability.
● Ensures sufficient mechanical strength and porous structure for 3D bone ingrowth anchorage.
● Humeral insert radius is slightly larger than the glenosphere, allowing sliding during motion to reduce peripheral load and prevent loosening.
Product Effectiveness – Composite Coating Implantation Study
26-week implantation study with 12 implant sites evaluated.
Abundant new bone observed at pore openings, with close bonding between coating and bone.
No fibrous capsule or inflammatory cells observed.
