DE CARDENAS CENTENO, Orlando M. et al. Revision knee replacement in an unusual case. Rev Cubana Ortop Traumatol [online]. 2008, vol.22, n.1, pp. 0-0. ISSN 1561-3100.

An unusual case of a 39-year-old female patient who underwent total arthrosplasty of the left knee 20 years ago is presented. This arthroplasty showed a useful life or a survival of 15 years, in spite of the fact that she was subjected to great demands and physical solicitudes. Starting from the "failure due to overuse and wasting", revision knee replacement surgery was performed, which was only useful for 2 years and 4 months, a period in which she presented a new prosthetic failure and it was necessary to make 2 more revisions with a late or deferred replacement for second time. The clinical, functional and radiographic results obtained after having applied the Knee Society Scoring KSS and the satisfaction degree (self-perceived health) expressed by the patient in the questionnaire used, Cincinnati Knee Rating System CKRS, made us feel satisfied with our decision and with the procedures carried out.
