Estructura de las articulaciones

Las articulaciones, en particular las articulaciones en bisagra como el hombro y la rodilla, son estructuras complejas formadas por hueso, músculos, membrana sinovial, cartílago y ligamentos, que están diseñados para soportar peso y movilizar el cuerpo a través del espacio. La rodilla está compuesta por el fémur (hueso del muslo), en la parte superior, y la tibia (hueso de la espinilla) y el peroné en la parte inferior. La rótula se desliza a través de un surco poco profundo en la parte frontal de la porción inferior del fémur. Los ligamentos y tendones se conectan a los tres huesos de la rodilla, los cuales están contenidos en la cápsula de la articulación (membrana sinovial) y son amortiguados por el cartílago.
