Sh. Liu et al., COMPARISON OF FUNCTIONAL KNEE BRACES FOR CONTROL OF ANTERIOR TIBIAL DISPLACEMENT, Clinical orthopaedics and related research, (303), 1994, pp. 203-210
Using a surrogate knee model, the ten custom functional knee braces th
at previous studies had shown to be most effective were tested for res
traint to anterior tibial displacement. Testing was performed at 20 de
grees knee flexion with applied forces ranging from 50 to 400 N. All b
races reduced anterior tibial displacement. Resistance to anterior tib
ial displacement depends directly on the brace design and is inversely
related to the applied force. Postbilateral hinge shell braces exhibi
ted the most resistance to anterior tibial displacement. Few braces we
re effective in controlling anterior tibial displacement comparable wi
th a normal knee at low forces. Most of the braces were less effective
at controlling anterior tibial displacement at high forces.
