Having thus described the knee stabilizer which embodies the principles of my invention, and specific examples of its use, the invention which I claim is:
1. A knee stabilizer for stabilizing medial-lateral, rotary, and posterior-anterior forces, including forces having an anterior tibial component, comprising:
- (a) a closed band system for surrounding the leg and thigh of a wearer, comprising a pair of medial and lateral femur uprights, a transverse posterior band connecting between the pair of femural uprights, a pair of medial and lateral tibial uprights, a transverse anterior band connecting between the pair of tibial uprights, and joint means pivotally connecting said two pair of uprights;
- (b) an anterior tibial shell comprising an anterior section mounted to said transverse tibial band adjacent the knee and thereby defining a first pressure point, said anterior section being connected between a medial section and a lateral section mounted, respectively, to said medial tibia upright and said lateral upright, said medial and lateral sections defining a posterior opening therebetween, strap means for spanning the posterior opening to cinch the shell against the wearer's leg and said tibial shell being shaped to closely fit the associated leg section, whereby said anterior tibial shell absorbs anterior tibial force components at said first pressure point and transmits the force via said tibia uprights to said femur uprights;
- (c) a posterior femural shell comprising a posterior section mounted to said transverse femur band proximate the knee and thereby defining a second pressure point, said posterior section spanning between a medial section of the femur shell and a lateral section thereof, said medial and lateral sections being mounted, respectively, to said medial femural upright and said lateral femural upright and defining an anterior opening, said femural shell being shaped to closely fit the associated thigh section and strap means spanning the upper anterior opening and spaced vertically above said posterior femural band for cinching the femural shell to the wearer's thigh, whereby the force transmitted to said femur uprights is transmitted via said second pressure point to said femur; and
- (d) said pair of femur uprights defining a lever pivotally positioned on the thigh at a fulcrum defined by said posterior femural band the posterior femural shell section such that cinching the femural shell anterior strap means pivots the upper end of said lever anteriorly about said fulcrum, thereby producing a rearwardly-directed force at the lower end of said lever for counteracting anterior tibial forces.
