From the desk of Dr Bradley Frick. There are many options with managing patients with knee pain. Options are adjusting and active care with up to full range of motion against gravity, then with resistance. With our sedentary lifestyles, lack of use of our knee along with hip joints, not using their full potential with assisted sitting and standing. Remember If you dont use it, you lose it. http://www.acatoday.org/content_css.cfm?CID=3996
