Femoro-tibial angles (FTA) of the 218 osteoarthritic knees in 141 patients were measured by x-rays at non-weight-bearing and weight-bearing.
In 98% out of 137 moderate cases, FTA were between 171 to 180 degrees at non-weight-bearing, being in 96% at weight-bearing.
Although at non-weight-bearing in 81 severe cases, FTA were measured over 180 degrees showing varus in 4 cases (5%) and under 171 degrees showing valgus in 6 cases (7%), they were measured in 17 cases (21%) and in 8 cases (10%) at weight-bearing, respectively.
