Hinge assembly for an orthopedic device

A knee brace having a longitudinal, central vertical axis, comprising:

• a first frame component adapted to secure to a user's upper leg and correspond to a femur;
• a second frame component adapted to secure about a user's lower leg and correspond to a tibia;
• a hinge assembly connecting the first frame component to the second frame component;
• wherein the hinge assembly is integrally formed from first and second end portions of the first and second frame components, respectively;
• wherein the first frame component defines first and second struts, and a first mast, the first mast being rigid and depending centrally from a first central segment extending between the first and second struts;
• wherein the second frame component defines third and fourth struts, and a second mast, the second mast being rigid and depending centrally from a second central segment extending between the third and fourth struts;
• wherein the first and second frame components are configured to laterally sway from the vertical central axis, the first and second masts are angled relative to the vertical central axis;
• wherein the first and second masts are arranged at first and second angles, respectively, at 3°±1.0° from the vertical central axis.
