An improved orthosis for correcting essentially all knee instabilities is disclosed herein. Generally, the orthosis comprises a joint structure formed from a pair of pivoting sidebars, upper and lower support assemblies, each of which includes C-shaped braces connected to the sidebars of the joint structure for supporting the pivoting portions of the sidebars over the knee joint, and a tibial retention means in the form of a Y-shaped tibial support member cantilevered from the bottom brace member of the lower support assembly for supporting the upper tibia against anterior displacements. The orthosis may further include resilient condylar pads disposed between the sidebars and the condyle regions of the knee in order to provide support against varus- and valgus-type knee instabilities. Finally, the orthosis may also include a femural retention means in the form of a Y-shaped member cantilevered from the upper C-shaped brace member for supporting the upper femur. The upper and lower C-shaped members and their respective tibial and femural support members are preferably integrally formed, and lined with an anti-slippage sheet material such as Neoprene TM .
