Abstract
A knee brace (10) is provided with a thigh collar (12) and a tibia collar (40) for securing the brace to the user's leg. A hinge (20) is connected to the thigh collar (12) and the tibia collar (40) in order to allow extension and flexion of the leg. The tibia collar (40) is connected to the hinge (20) via a connecting rod (26) upon which the tibia collar (40) may rotate and piston vertically. The desired range within which tibia collar (40) may rotate and piston may be adjusted by cams (34 and 36). An elastic wrap (56) is attached to the thigh collar (12) and the tibia collar (40) in order to facilitate proper rotation of the leg.
