Knee Positioners are used to keep the legs in a comfortable position while recovering from the surgery, especially lower body procedures. They help promote better blood circulation and relieve tension in the lower back. Pressure is taken off the sore knees, which helps reduce the extension related knee pain. Numbness and swelling in the knees may also be reduced. Shop a wide range of knee positioners from the top-selling brands like Span America, Hermell Products, Hudson Medical, etc. and avail great discounts!
