AI Technical Summary

Technical Problem

Current knee prostheses often require significant bone resection and can impinge on adjacent soft tissues, limiting flexibility and compatibility with varying patient anatomies.

Method used

The design of a femoral component with bulbous posterior geometry, differential condyle heights, and specialized cam and intercondylar notch features that minimize bone resection and soft tissue impact, allowing for deep flexion and reduced component wear, while accommodating anatomical variability through 'standard' and 'narrow' component sizes.

Benefits of technology

This design enhances articular characteristics, reduces bone resection, and minimizes soft tissue impingement, enabling deeper flexion and broader anatomical compatibility, thus improving surgical outcomes and patient mobility.

Abstract

An orthopedic knee prosthesis includes a femoral component (20, 120, 220) which exhibits enhanced articular features, minimizes removal of healthy bone stock from the distal femur, and minimizes the impact of the prothesis on adjacent soft tissues of the knee.
