1. A knee brace comprising:
a main body having an anterior portion, a medial portion, a posterior portion and a lateral portion, wherein said main body is adapted for positioning over the knee with said anterior portion adapted to cover at least in part the anterior side of the knee, said medial portion adapted to cover at least in part the medial side of the knee, said posterior portion adapted to cover at least in part the posterior side of the knee and said lateral portion adapted to cover at least in part the lateral side of the knee; a longitudinal support assembly including an upper longitudinal member, a lower longitudinal member, and a hinge rotatably connecting said upper longitudinal member and said lower longitudinal member, wherein said longitudinal support assembly is positioned at said lateral or medial portion of said main body and is correspondingly adapted to align with the corresponding lateral or medial side of the knee; a knee buttress adapted for positioning against the knee and applying a variable compression force to a compression surface on the knee; a buttress retention flap extending from said lateral or medial portion of said main body opposite said longitudinal support assembly and overlaying said knee buttress; a cam having an operating surface; and a tensioning line having a first anchored end and a second anchored end and following a tensioning line path including a first tensioning line anchor, a second tensioning line anchor and said operating surface of said cam positioned between said first and second tensioning line anchors, wherein said tensioning line operatively connects said cam to said knee buttress via said buttress retention flap, thereby enabling said knee brace to automatically adjust said variable compression force applied to the compression surface in response to rotation of said upper longitudinal member and said lower longitudinal member relative to one another about said hinge. |
