A knee brace for proprioceptively treating a patient comprises a sleeve having an anchor strap and a viscoelastic pad. The sleeve defines inner and outer sleeve surfaces and is configured to envelop the patient's knee. The anchor strap is circumferentially wrappable about the outer sleeve surface and defines an inner strap surface. The anchor strap has an intermediate anchor portion disposed on the inner strap surface between opposing end anchor portions that are releasably securable to the outer sleeve surface such that tension in the anchor strap may be selectively adjusted. The knee brace includes an elastic band extending along the inner strap surface. The viscoelastic pad is securable on the inner sleeve surface generally opposite to the elastic band such that pressure may be applied to the patient's infrapatellar tendon when the anchor strap is extended over the outer sleeve surface.
