Summary

This study shows a custom intramedullary nail effectively achieves knee fusion in 14 patients, especially those with challenging infections or failed prostheses. Most patients experienced rapid healing and regained independence with minimal complications.

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering

Context:

  • Knee arthrodesis is a salvage procedure for severe knee destruction.
  • Challenging indications include recurrent periprosthetic joint infections and nonunions.
  • Traditional methods may have limited success in complex cases.

Purpose:

  • To evaluate the efficacy of a customized intramedullary nail for knee arthrodesis.
  • To assess outcomes in patients with difficult-to-treat knee conditions.

Summary:

  • Fourteen patients underwent knee arthrodesis with a custom intramedullary nail.
  • Indications included prosthetic joint infection, septic arthritis, aseptic loosening, and nonunion.
  • A two-stage protocol was used for infected joints, with a mean follow-up of 19 months.
  • Early weight-bearing was initiated in most patients, with a high rate of bone healing (13/14) within a mean of three months.

  • Complications were infrequent and manageable.

    • Impact:

    • Custom intramedullary nailing offers a viable solution for knee arthrodesis in complex cases.
    • This technique facilitates bone fusion and functional recovery, particularly in patients with recurrent infections.
    • The study highlights the potential for improved patient independence after salvage surgery.
