Abstract

UNA PROTESIS DE RODILLA CONSTA DE UN COMPONENTE FEMORAL EN EL QUE LOS CONDILOS TIENEN SUPERFICIES DE CONTACTO CONTINUAS PARA LA SUPERFICIE DE SOPORTE DE LA TIBIA Y EN EL QUE EL RADIO SAGITAL ES CONSTANTE DESDE LA ZONA POSTERIOR HASTA UN PUNTO ANTERIOR AL PUNTO MAS DISTAL. LA SUPERFICIE DE SOPORTE DE LA TIBIA (72) TIENE UNA FORMA CURVA QUE CORRESPONDE EXACTAMENTE CON LA DE LAS SUPERFICIES CANDILARES FEMORALES. EL COMPONENTE DE LA TIBIA CONSTA DE UN COMPONENTE DE MENISCO PLASTICO SOSTENIDO EN UNA PLATAFORMA METALICA PARA EL MOVIMIENTO DESLIZANTE EN DIRECCION ANTERIOR-POSTERIOR Y LA SUPERFICIE DE ACOPLAMIENTO (71) ENTRE EL MENISCO Y LA PLATAFORMA TIENE UNA CURVATURA SAPITAL MAYOR QUE EL RADIO SAPITAL DE LOS CONDILOS FEMORALES .
