ABSTRACT:
A knee brace and wrap assembly for protecting and stabilizing the knee joint against overextension, twisting, lateral impact, injury associated with immense muscular effort of the leg muscle and particularly the quadriceps, as well as other such trauma as can result from rigorous activity, such as football or skiing. The brace includes upper and lower leg support means secured to the outer sides of the thigh and calf. The support means can be contoured pads connected by a composite hinge assembly having three pivot points such that the pads will rotate relative to one another upon rotation of the knee about an axis that generally follows that of the knee. The composite hinge assembly has first and second fixed members secured to the leg pads, and first and second movable members comprised as hinge plates pivotally connected to each other and to the fixed members. Stop members limit rotation of the hinge assembly in both directions of rotation of the knee to limit rotation of the knee. According to another form of the invention, support means can be comprised of upper and lower wrap assemblies, each having inner and outer elastic wraps for installation on a leg.
