Previous kinematic studies on the effects of knee braces have concentrated primarily on the anterior cruciate ligament and the effects of bracing to stabilize the knee that has a deficiency of this ligament1-23. The majority of those studies have concentrated on the analysis of functional knee braces with use of arthrometers2,3,5-8,10-15. Other studies have concentrated on the analysis of femorotibial translation through the use of roentgen stereophotogrammetric analysis techniques4,9,16,17, subjective evaluation of bracing by categorizing pain and functional ability18-22, and the determination of the effectiveness of different types of knee braces, such as cast bracing23-26. Although minimal research evaluating the efficiency of off-loading braces for the treatment of unicompartmental arthritic degeneration has been performed, a previous study with an initial fluoroscopic analysis determined that bracing is an effective treatment for osteoarthritis of the knee in nonobese patients under weight-bearing conditions27. In that investigation of a single type of brace, the results were not assessed for three-dimensional motion and the study did not determine whether different types of osteoarthritic knee braces would perform well under similar conditions.
