Overview

Narrative review discusses corrosion-related failures in modular total knee arthroplasty, suggesting improved diagnostic protocols.

Key Points

  • The aim is to highlight the risk of corrosion-related failures in modular total knee arthroplasty and identify underlying mechanisms.
  • Conducted a narrative review of published clinical cases regarding corrosion in modular TKA.
  • Analyzed case reports to identify descriptions of failure mechanisms, specifically MACC.
  • Suggested improvements in surveillance protocols and imaging strategies for early detection.
  • Identified mechanically assisted crevice corrosion as a key failure mechanism in modular TKA junctions.
  • Noted that adverse local tissue reactions and fatigue fractures can occur even in well-fixed implants.
  • Emphasized the need for better diagnostic tools and design innovations to prevent future failures.
