Revision Arthroplasty: Etiology of Failure, Reconstructive Principles, and Contemporary Implant Solutions

This chapter provides a comprehensive analysis of revision total joint arthroplasty, addressing the epidemiology and pathomechanics of implant failure modes including aseptic loosening, periprosthetic joint infection, instability, stiffness, and periprosthetic fracture. Reconstructive principles for managing significant bone loss are reviewed, with detailed discussion of classification systems, augments, sleeves, cones, and structural allograft strategies in the context of both hip and knee revision surgery. The chapter synthesizes evidence on surgical outcomes, infection eradication rates, and long-term implant survivorship, and presents a framework for evidence-based surgical decision-making in the complex revision setting.
