Abstract
Knee flexion contracture is observed sometimes in the elderly walking. The serial cast method has been successful in treating knee contracture secondary to neurological diseases after injection of botulinum toxin. We focus on 3 cases: all patients were unable to walk because of knee flexion contracture. They have benefited from our protocol of serial casts and at the end of the treatment, knee flessum was less. All patients have recovered the ability to walk. Our method is simple and fast. For these 3 patients, we could discuss percutaneous needle tenotomies but it requires a trained team.
