Growing, active children frequently develop Osgood-Schlatter disease, a painful bump below the kneecap. Active children during puberty place a great amount of stress on the growth plate in the knee due to the size difference of the surrounding muscle groups. Usually, the disease will resolve itself in about 12-24 months, or when the growth spurts begin to slow. BioSkin's Knee Strap uses compression and gel-pads to alleviate the pain during this time, allowing for continued activity.
