Dynamic stabilizing knee support system

A knee brace assembly comprising:

• a hinge;
• and
• an active compression assembly including a proximal compression system adapted to be secured to a thigh, a distal compression system adapted to be secured to a calf, a first inelastic strap moveably coupled to the proximal compression system and distal compression system, and a second inelastic strap moveably coupled to the proximal compression system and distal compression system, wherein the proximal compression system is pivotally connected to the distal compression system via the hinge and at least one of the first inelastic strap and the second inelastic strap have a first portion and a second portion that cross over each other proximal to the hinge and at least one of the first inelastic strap and the second inelastic strap have a third portion and a fourth portion that cross over each other distal to the hinge,
• wherein the active compression assembly dynamically increases compression of soft tissue in the thigh and calf when a leg is extended and dynamically decreases compression of soft tissue in the thigh and calf when the leg is in flexion.

A knee brace assembly comprising:

• a sleeve comprising an opening for alignment over a patient's patella;
• a first compression system positioned proximal to the opening;
• a second compression system positioned distal to the opening;
• and
• a hinge assembly rotatably coupling the first compression system to the second compression system.
