Abstract:
The quantitative effect of flexion and rotation on apparent varus/valgus deformity was analyzed, and the expected amount of deformity as a function of flexion rotational artifact determined, as shown by use of formulae and tabulated computational results. These results were calculated first when no deformity was present initially, and also for varying amounts of initial deformity.
