Forrest Gump corría sin parar, buscando la libertad o simplemente un propósito de vida saludable, pero ¿qué hubiera pasado si hubiera tenido que detenerse por un dolor de rodilla? 

Correr no solo es una actividad liberadora, sino que es accesible y sencilla de desarrollar, necesitamos un poco de tiempo y ponernos las zapatillas para ejercitarnos. ...

en ocasiones el cuerpo del runner alerta de un desequilibrio dentro del sistema, el dolor de rodilla, que le impide seguir con la carrera o incluso debe detener el entrenamiento por un periodo de tiempo prolongado. 

...sin tomar en consideración aspectos clave como un aumento del volumen —salir todos los días de la semana— y la intensidad cuando se lleva mucho tiempo sin actividad... 

En la mayoría de las ocasiones, el dolor de rodilla en el corredor se debe a dos causas, el síndrome del dolor patelofemoral y el síndrome de la cintilla iliotibial, aunque también puede deberse, en menor medida, a tendinopatías... 

...lesiones de menisco, condromalacia o desequilibrios musculares. 

En otras ocasiones, la debilidad de los músculos de la pantorrilla —gemelo y sóleo— por una inestabilidad de tobillo, acaban afectando a la fuerza que se transfiere a la rodilla, forzando un valgo —rodilla hacia dentro o piernas en X— durante la carrera... 

En cuanto al síndrome de la cintilla iliotibial, se refiere a un dolor en la zona externa de la rodilla, debido a la fricción de la cintilla iliotibial sobre el epicóndilo del fémur. 

Este síndrome es multifactorial, pero principalmente está relacionado con una mayor aducción de la cadera, una mayor rotación interna de la rodilla, y una menor eversión del pie —limitación en la movilidad del tobillo

Forrest Gump ran non-stop, seeking freedom or just a healthy life purpose, but what would have happened if he had to stop for a knee pain? 

Running is not only a liberating activity, but it is accessible and easy to develop, we need a little time and put on our shoes to exercise. 

...sometimes the runner's body warns of an imbalance within the system, knee pain, which prevents him from continuing with the race or even has to stop training for an extended period of time. 

...without taking into account key aspects such as an increase in volume - going out every day of the week - and intensity when he has been without activity for a long time... 

In most cases, knee pain in the runner is due to two causes, patellofemoral pain syndrome and iliotibial strap syndrome, although it can also be due, to a lesser extent, to tendinopathies... 

...meniscus injuries, chondromalacia or muscle imbalances. 

At other times, the weakness of the calf muscles -twin and soleus- due to ankle instability, end up affecting the force that is transferred to the knee, forcing a valgus -inward knee or X legs- during the race... 

As for iliotibial band syndrome, it refers to a pain in the outer area of the knee, due to the friction of the iliotibial band on the epicondyle of the femur. 

This syndrome is multifactorial, but it is mainly related to a greater adduction of the hip, a greater internal rotation of the knee, and a lower eversion of the foot - limitation in the mobility of the ankle
