Knee salvage in revision arthroplasty after massive bone loss of the femur condyles (>= Engh III) with a single-modular-hinged knee revision implant

摘要

Massive bone loss of the femur condyles in revision arthroplasty often requires modular-hinged revision implants to restore a stable joint situation. In the present series, the outcome after knee revision surgery using a single modular-hinged revision implant in patients with severe bone defects (> Engh III) is investigated.
