Case: Two women (aged 35 and 29 years) with intractable chronic knee infection of tumor prostheses opted for amputation. As only the trochanteric region could be preserved, we resected remaining proximal femur created a 15-cm long stump using unaffected thigh soft tissue to avoid drawbacks ultra–high-thigh amputation conventional hip disarticulation. Both had no contracture, move their voluntarily, ambulated standard transfemoral prosthesis without pelvic belt at 4-year 3-year follow-ups, respectively. Conclusion: Our procedure might benefit patients who require amputation, preservation femoral region.
