Reduction in Bone Volume Resection with a Newer Posterior Stabilized Total Knee Arthroplasty Design

摘要

Background Posterior stabilized total knee arthroplasty requires an intercondylar notch to accommodate the cam housing that articulates with the tibial post to create femoral rollback required for deep flexion. The volume of bone resected for the intercondylar notch varies with implant design, and newer designs may accommodate high flexion with less bone resection.
