Limb Salvage After Failed Infected Total Knee Arthroplasty: A Comparison of Cement-Based Artificial Arthrodesis and External Fixator Arthrodesis

Background

Persistent or recurrent periprosthetic joint infection after total knee arthroplasty is a devastating complication. When revision fails, knee arthrodesis remains an important limb-salvage option. Cement-based artificial arthrodesis may provide an alternative when extensive bone loss or soft-tissue compromise limits conventional fusion, but comparative evidence is scarce.
