A 22-year-old man in the UK has made headlines around the world after sharing how a rotationplasty saved his life. Rotationplasty (commonly known as a Van Nes rotation or Borggreve rotation) is essentially an autograft where a portion of a limb is excised and the distal (remaining) limb below rotated and reattached. It is most commonly used to transfer the ankle joint to the knee following removal of a distal femoral bone tumour. The rotation is required because the ankle flexes in the opposite direction to the knee.
