Summary

Treating infected total knee arthroplasties is challenging. One-stage prosthetic reimplantation offers better outcomes than debridement alone or two-stage reimplantation for most patients, while arthrodesis remains an option for complex cases.

Area of Science:

  • Orthopedic Surgery
  • Infectious Disease Management
  • Biomaterials Science

Context:

  • Infected total knee arthroplasties (TKAs) pose significant challenges in revision surgery.
  • Septic complications following TKA require effective management strategies to preserve joint function and eradicate infection.
  • Patient factors and prosthesis type influence treatment outcomes in infected TKAs.

Purpose:

  • To evaluate the functional results and septic outcomes of different surgical treatments for infected total knee arthroplasties.
  • To compare the efficacy of articular debridement, prosthetic reimplantation (one-stage and two-stage), and femoro-tibial arthrodesis.
  • To identify optimal management strategies based on patient condition and infection characteristics.

Summary:

  • Articular debridement alone was ineffective in eradicating infection in all cases.

  • Prosthetic reimplantation was successful in 7 out of 10 cases, with one-stage procedures yielding better functional results.
  • Femoro-tibial arthrodesis was achieved in 10 out of 15 patients, with a higher union rate when stabilized by intramedullary fixation.

    • Impact:

    • One-stage prosthetic reimplantation is recommended as the preferred procedure for infected TKAs due to its effectiveness in infection eradication and improved clinical results.
    • Two-stage reimplantation remains a viable option, but certain patient conditions may preclude its use.
    • Femoro-tibial arthrodesis serves as a reliable salvage procedure for complex cases, particularly when combined with intramedullary fixation, though it can lead to significant functional limitations.
