Functional ambulation with bent knee prostheses for an adult with bilateral 90 degrees knee flexion contractures—A case report

An adult male who never stood, ambulating on all four due to bilateral severe knee flexion contractures, since his childhood, was 21 years of age, and not deterred by his condition, was pursuing his higher education. He was coaxed by his friends to seek medical opinion and it was decided to give a trial and let the client have a feel of bipedal stance and ambulation. Although there is a paucity of recent evidence on the use of bent knee prosthesis, the trial successfully restored the dignity.
