title: [Disarticulation of the knee. Surgical technic--prosthesis fitting].
abstract: The authors describe a modified technique for knee joint disarticulation surgery. Their approach provides two flaps, one medial and one lateral, which result in a posterior, longitudinal scar that remains outside the contact areas of the prosthesis. They abrade the lateral and posterior aspect of each condyle, peeling out the articular cartilage and re-covering the condyles with the joint capsule. This technique allows a satisfactory stability in prosthetic rotation, and improves the appearance of the artificial limb. For post-operative rehabilitation the authors use a tridimensional alignment jig and a prosthetic ankle with three degrees of freedom: flexion-extension, lateral-medial motion and rotation, making easier the swing phase while maintaining the obvious advantages of a pilon-type prosthesis.
