The Klassic HD® Hip System evolved from the optimal design features of the most successful tapered stems and acetabular constructs.
Our instrumentation is streamlined to offer surgeons both ease and flexibility of use. Three instrumentation trays offer reduced shipping and sterilization costs, require less storage space, and lower instrumentation costs.
State-of-the-art design and materials offer surgeons a premium implant system, while intuitive design allows efficiency.
The patented1 Klassic HD Femoral Stem features a double-wedge taper with Ti-Coat® ultra-porous coating for biological fixation, mid-stem grit blasting, and a smooth polished distal tip. A Zweymüller-style body and a relieved shoulder make this workhorse stem compatible with A-, B-, and C-type bone, available in both standard and offset for a variety of patient anatomy.
The patented2 Klassic HD Acetabular Cup is a thin-walled, ultra-porous hemispherical cup with 1.5mm of press-fit at the rim. Ti-Coat porous coating offers 60% porosity for biological fixation.
The Klassic HD Acetabular Insert features XLPE and E-Link® Vitamin E polyethylene and offers one insert for every cup to establish a minimum poly thickness (5mm) to ensure that the center of rotation stays constant.
E-Link Poly is a Vitamin E stabilized highly cross-linked ultra high molecular weight polyethylene. Vitamin E is blended into the UHMWPE in powder form, then compression molded, and cross-linked by gamma radiation to 10 MRads. E-Link utilizes Vitamin E which has been shown to quench free radicals generated from the cross-linking process yielding oxidative stability.3 XLPE is highly cross-linked at 7.5 MRads and remelted for oxidative stability.4
Femoral heads are provided in BIOLOX®delta Ceramic or Cobalt Chrome.
