There was a significant correlation between preoperative lateral femoral angle and varus angle (p < 0.
Forty-four knees in 32 patients with a varus preoperative lateral femoral angle of more than 175[degrees] had total knee arthroplasties at our hospital from 1987 to 1996, and these knees were evaluated in this study.
The lateral femoral angle was defined as the lateral angle formed by the femoral and tibial anatomical axes (Fig.
Statistical analyses were performed to assess the correlation between the preoperative lateral femoral angle and the varus angle, valgus angle, sum of the varus-valgus angle, and difference of the varus-valgus angle.
In order to assess the association of the preoperative severity of the varus deformity to the postoperative ligament imbalance, the patients were divided into two subgroups, a subgroup of the knees with preoperative lateral femoral angle of less than 190[degrees] (n = 24) and another subgroup of those with knees with a lateral femoral angle of more than 190[degrees] (n = 20).
The results of this study revealed for the first time that there are significant correlations between the preoperative lateral femoral angle and the varus angle (p < 0.
The subjects in this study had appropriate bony alignment with a mean postoperative lateral femoral angle of 175.
