The knee is the largest joint in the body and is located in the central part of the lower limbs serving and the union between the thigh and leg. In terms of bones, it is made up of the bones of the femur, tibia and patella. Between the femur and tibia, there are two crescent-shaped fibrocartilaginous structures called menisci. Overall, they allow for flexion-extension movement facilitated by the existence of different ligaments and muscles that are involved in stabilization and joint mobility. To the flexion and extension movement of the knee, we add a certain capacity for rotation when it is flexed.
This wide range of movement and its location is what generates, on certain occasions, the appearance of different injuries associated with sports activity and/or degenerative processes or “osteoarthritis”, over the years.
