The knee is one of the largest and most complex joints of the body, having a complex functionality. The knee joint must be mobile and flexible to allow flexion and extension of the lower limb and also stable to support the entire weight of the body.

Walking, running and accelerating suddenly, jumping, rotating on the heel, braking, stopping more or less suddenly, are roles of the knee, which generate numerous pressures, managed by the bone, ligamentous, meniscal and muscular structures of the knee.

Exercise builds muscle mass around the knee joint, the muscles that stabilize the joint and help prevent injuries. After the resting period necessary to recover after pain, the trainings will be resumed, initially those with low impact, exercises in water being a good option. The workouts will be resumed gradually, with a slight increase in their intensity to avoid the recurrence of pain.

Wearing appropriate shoes with a good sole reduces the risk of slipping. Shoes with low heels and/or soft rubber soles are preferred. The stairs and hallways of the house must be lit and the floors dry to reduce the risk of slipping.

Sleeping in the wrong position can accentuate knee pain. The preferred sleep position is sideways, with a pillow between the knees.

Most of the time, knee pain occurs due to overloading of the joint. Repetitive movements and prolonged standing can wear out the joint and cause pain.

The shoes wear out with time, losing their plantar support and the ability to run well on the ground. This can create imbalances in the leg, and implicitly an uneven distribution of forces around the knee, ending with the appearance of knee pain.
