An improved orthotic knee brace system for single and multiple posterior, anterior and lateral knee injuries includes first and second depending frameworks for attaching around a human leg, respectively, above and below the knee joint, the frameworks being hingedly interconnected for relative movement during walking. One of the frameworks bears a cammed surface adjacent the other framework, which other framework has a tibia-stabilizing force transfer mechanism in the form of a lever pivoted thereto. One arm of the lever bears an adjustable contact member adapted to contact the cammed surface, while another arm of the lever is pivotably connected to a tibia-bracing component adapted to wrap around the lower leg portion to prevent tibial displacement during knee movement, as in walking. Preferably, each framework has depending side strips connected to wrap-around leg straps, and the strips of one framework have offset members bearing the cammed surfaces. Multiple sets of the frameworks and tibia-stabilizing force transfer mechanisms can be positioned around the leg to correct multiple knee injuries. The system and its method of use are simple and effective.
