Knee brace with lightweight structure

1. A knee brace for correction of abnormalities of a knee that is a varus or a valgus knee, or for correction of various forms of osteoarthritis, wherein said knee has a femoral area and a tibial area, and an outer side and an inner side of the varus knee or the valgus knee, comprising:

a single upright for the femoral area of the knee wherein said femoral area has a front half and a rear half and a single upright for the tibial area of the knee wherein said tibial area has a front half and a rear half, the single uprights being connected and hinged to a single articulated joint which can be positioned close to one side of the knee, generally the outer side of the varus knee or the inner side of the valgus knee, each of said single uprights having two free ends remote from said single articulated joint at opposite directions from each other, wherein the two free ends of each of the single uprights which are positioned in opposite directions with respect to said single articulated joint are each shaped and fitted with a substantially semicircular structure, one of which is configured to wrap around the front half of the femoral area of the knee and another that is configured to wrap around the rear half of the tibial area of the knee, each of the substantially semicircular structures including a substantially semicircular appendage or pad to be positioned on a corresponding opposite side of a leg, the substantially semicircular appendage or pad of each substantially semicircular structure comprising said substantially semicircular appendage or pad being covered in soft cloth and mounted on a jointed hinged structure thereby providing a thrust and elastic compression adjustable element.

2. The knee brace of claim 1 wherein said jointed hinged structure of said thrust and elastic compression adjustable element has a spherical ball, positioned on a base integral with the substantially semicircular appendage or pad of the knee brace and extending from said base toward a housing in a support which holds said thrust and elastic compression adjustable element, whereby said spherical ball is compressed within a ball shaped socket thereby providing a ball joint inside said housing in said support which holds said thrust and elastic compression adjustable element, said spherical ball being confined in said ball shaped socket within said housing, said thrust and elastic compression adjustable element being pivotable about said ball joint in an arcuate direction thereby providing a thrust and elastic compression adjustable element.
