Knee Disarticulation—Femoral Shortening Osteotomy

CASE: A 28-year-old active-duty man who had failed limb salvage after open Gustilo 3C knee dislocation underwent knee disarticulation-femoral shortening osteotomy, involving an 8-cm femoral resection osteotomy and stabilization with intramedullary nail. At 16-month follow-up, the patient achieved osseous union at the osteotomy site without need for reoperation, was ambulating using a prosthesis daily, and was running weekly. CONCLUSION: Knee disarticulation with femoral shortening osteotomy preserves the advantages of a knee disarticulation amputation and solves the historical problem of knee length difference with this amputation level.
