Metal or Modularity: Why do Metal Backed Tibias Have Inferior Outcomes to All-Polyethylene Tibial Components in Patients with Osteoarthritis

Background Biomechanical studies have suggested improved stress distribution in metal-backed (MB) compared to all-polyethylene (AP) tibias, but such potential benefits have not been realized clinically. The purpose of this investigation was to analyze the outcomes of AP components in patients with p...
