A knee brace of near universal application for any patient needing left or right knee stabilization, and/or suffering from arthritis, bone on bone contact, and/or narrowed joint spacing in either left or right knee. Brace is mountable on outside or inside of left or right knee. Brace includes a selectively activated force device for exerting pressure directly by pushing at a joint line of a knee or indirectly by pulling on a knee strap wrapped around knee and force device. A base, adjacent to the force device, at least partially resists pressure of force device, and is adjacent a flexor that allows knee flexing when brace is worn. Extensions connect flexor with base and force device to thigh and calf attachment straps. A knee strap may be used with force device. Knee strap has opening to fit over patella and straps for wrapping around knee without hampering knee flexion.
