Knee Pain (Patello-Femoral syndrome)

"I suffer from a sharp pain in the knee when walking up or down the stairs. This pain also occurs when I leave my car or get out of my chair. I wore a knee guard for several months which helped only slightly: however, the pain and crunching/clicking sensation returned..."

This type of knee pain is commonly caused by flattening of the foot's arch. Excess Pronation - or rolling over of the foot - causes the lower leg (the tibia & fibia) to rotate internally. In turn, this will put excessive forces on the kneecap and over time it will weaken the muscles and ligaments in the knee joint. Often, a 'grinding' sensation is experienced in the knee, combined with a sharp pain
By supporting the arches and re-aligning the lower limb, VAS Performance Plus footbeds stop the leg from rotating internally, thereby effectively taking away this common cause of knee pain.
