Abstract
A brace for supporting a knee joint is disclosed which is specifically adapted for use in athletic, i.e. sports, applications. The brace is formed by a pair of frame members disposed on opposite sides of the knee joint which are pivotally connected adjacent one end by way of ratio-swing hinge members. Attached to the inner surface of the lower frame member is a tibia pad which is used to provide a firm interface between the lower frame member and the portion of the knee joint adjacent the crest of the tibia. Means are additionally provided to adjust the position of the tibia pad relative to the knee joint. The brace further includes a patella cap which is positionable over the knee cap of the user.
Claims7
A knee brace comprising:
- an upper frame member and a lower frame member formed from fiber-reinforced composite materials, each having a generally Y-shaped configuration, comprising a singular, central portion which bifurcates to a pair of extensions having end portions, said upper frame member being sized to be positionable above the knee joint of a user and said lower frame member being sized to be positionable below the knee joint of the user, such that the end portions of the extensions of each of said frame members are disposed laterally on opposite sides of the knee joint and the central portion of each of said frame members is disposed adjacent the front of the user's leg;
- a pair of hinge members disposed laterally on opposite sides of the knee joint when the knee brace is attached to the user's leg and connected to the end portions of the extensions of each of said frame members such that said frame members may pivot about a primary pivot axis to allow bending of the knee joint, said hinge members including metal tabs formed thereon, the composite materials used to form the frame members being laminated about the metal tabs during the fabrication of the frame members, thus rigidly securing the hinge members to the end portions of the frame members and increasing the structural integrity of the knee brace;
- a tibia pad removably attachable to an inner surface of said lower frame member to provide a firm interface between said lower frame member and the portion of the knee joint adjacent the crest of the tibia;
- and
- means associated with said tibia pad for adjusting the position of the tibia pad relative the portion of the knee joint adjacent the crest of the tibia.

A knee brace comprising:
- an upper frame member sized to be positionable above the knee joint of the user and a lower frame member sized to be positionable below the knee joint of the user, each of said frame members including an end portion configured so as to be disposed laterally on opposite sides of the knee joint when the knee brace is attached to the user's leg and a central portion disposed adjacent the front of the user's leg when the knee brace is attached thereto;
- a pair of hinge members disposed laterally on opposite sides of the knee joint when the knee brace is attached to the user's leg and connected to the end portion of each of said frame members to pivot said frame members about the knee joint;
- a tibia pad removably attachable to an inner surface of said lower frame member to provide a firm interface between said lower frame member and a portion of the knee joint adjacent the crest of the tibia;
- and
- means removably interposed between said tibia pad and the inner surface of said lower frame member and being sized and configured for adjusting the position of said tibia pad relative to the portion of the knee joint adjacent the crest of the tibia.

- a tibia pad removably attachable to an inner surface of said lower frame member to provide a firm interface between said lower frame member and the portion of the knee joint adjacent the crest of the tibia;
- and
- means removably interposed between said tibia pad and the inner surface of said lower frame member and being sized and configured for adjusting the position of the tibia pad relative to the portion of the knee joint adjacent the crest of the tibia.
