Use of Van Nes rotationplasty to manage a burnt knee

An 11 month old child sustained a deep burn injury to the left knee causing total destruction and sequestration of the knee epiphyses. The ensuing leg length discrepancy with growth was managed by a Van Nes rotationplasty at age four with a good immediate functional result using a below 'knee' prosthesis and the prospect of continuing ambulation as he grows. The surgical options for managing this problem are discussed.
