The GenuTrain S knee support also functions as a hinged patella knee brace with a viscoelastic patella donut that stabilizes the patellofemoral joint with repeated bending and straightening of the knee. The knee brace features anatomically shaped side hinge bars that fit inside lateral guide channels made from thermomolded plastic. The knitted fabric material is contoured to fit to the shape of the knee and the side bars are moldable to customize the fit of the brace.
