Dynamic patella stabilization is provided through the entire range of motion, because the buttress is independent of the support wrap. Successfully controls malaignments of glide, medial/lateral tilt and anterior/posterior tilt. Directional force flap holds the buttress in place. Neoprene condyle pads make for protection, comfort, and they reduce chaffing. Padded hinge covers allow for sports participation. Wide biaxial hinges enhance medial/lateral stability and prevent hyperextension. Anterior closure for easy application; open popliteal for added comfort; and 1/8" Kuhl perforated neoprene construction for cool compression. Latex free.
