RESUMO
Objetivo. Evaluar los resultados de la fijación de rodilla sin fusión ósea, con clavo intramedular e interposición de cemento. Material y métodos. Estudio retrospectivo de 29 prótesis total de rodilla infectadas con datos recogidos prospectivamente y seguimiento medio de 4,2 años (3-5). Resultados. Las complicaciones fueron 2 infecciones recurrentes, una fractura periimplante y una erosión cortical en la punta del componente femoral, siendo todas revisadas con buen resultado. La dismetría media fue 0,8 cm, con 24 < 1 cm. Veinticinco pacientes no referían dolor. El valor medio de WOMAC-dolor fue 86,9, WOMAC-función 56,4, SF12-físico 45,1, y SF12-mental 53,7. Cuatro pacientes precisaron andador y solo 2 eran dependientes para actividades diarias. Conclusiones. El clavo Endo-Model Link® es un efectivo método de fijación de rodilla, restaurando la alineación del miembro y adecuada longitud del mismo (AU)
Objective. To evaluate the outcome of knee fixation without bone fusion using an intramedullary modular nail and interposed cement. Material and methods. Retrospective study of 29 infected total knee arthroplasties with prospective data collection and a mean follow-up of 4.2 years (3-5). Results. Complications included 2 recurrent infections, 1 peri-implant fracture, and 1 cortical erosion due to the tip of the femoral component. All of these were revised with successful results. The mean limb length discrepancy was 0.8 cm, with 24 < 1 cm. Twenty-five patients reported no pain. The mean WOMAC-pain was 86.9, WOMAC-function 56.4, SF12-physical 45.1, and SF12-mental 53.7. Four patients needed a walking frame, and only two were dependent for daily activities. Conclusions. The Endo-Model Link nail is an effective method for knee fixation that restores the anatomical alignment of the limb with adequate leg length (AU)
