The Allofit™ Acetabular Cup System

Patented Ridgelock™ surface designed for easy insertion and maximum stability

The Allofit system is designed to achieve maximum stability in virtually every press-fit situation. Since its introduction in 1993, more than 40,000 Allofit shells have been implanted. Mid-term results are outstanding. The Allofit Acetabular Cup System
The patented Ridgelock surface provides optimum bone engagement. The forged “teeth” change direction across the surface for maximum stability and ease of insertion. Secondary stability is enhanced by the grit-blasted titanium surface. The Allofit system offers an industry-leading set of alternative bearing options, addressing the most dominant complication in Total Hip Arthroplasty: late loosening due to osteolysis.
