Abstract
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 geometries of rotational movements and ranges. The antifriction mechanical joint has a first bearing plate and a second bearing plate which mate with bearing surfaces of a link. The bearing plates each have a cavity therein and a cam rests in each cavity and is attached to each of the bearing surfaces of the link. Rollers fit between the cams and the cavity so when the joint is flexed, there is only rolling movement between the rollers and the contact surfaces of the cams and rollers.
