An orthopedic brace, specifically for a knee, has an antifriction mechanical joint to provide easier movement and has the ability of being custom made for different geometrics of rotational movements and ranges. The antifriction mechanical joint has a first bearing plate (40) and a second bearing plate (42) which mate with bearing surfaces (50) of a link (48). The bearing plates (40, 42) each have a cavity (44, 46) therein and a cam (54, 56) rests in each cavity (44, 46) and is attached to each of the bearing surfaces (50) of the link (48). Rollers (60) fit between the cams (54, 56) and the cavity (44, 46) so when the joint is flexed, there is only rolling movement between the rollers (60) and the contact surfaces of the cams (54, 56) and rollers (60). |
