Patellofemoral characteristics in patients with increased femoral anteversion.
In this study, the association between increased femoral anteversion and the characteristics of the patellofemoral joint was investigated in adults. In 17 female control patients, the anteversion angle of the femoral neck measured 12 degrees +/- 8 degrees and 11 degrees +/- 9 degrees for the right and left side, respectively. The sulcus angle of the patellofemoral joint was 145 degrees +/- 10 degrees and 146 degrees +/- 11 degrees, the congruence angle 7.2 degrees +/- 14 degrees and 7.8 degrees +/- 15 degrees, and the lateral patellofemoral angle 5.9 degrees +/- 6 degrees and 5.7 degrees +/- 6 degrees, respectively. In 15 female patients who were evaluated for clinical symptoms of increased femoral anteversion, the anteversion angle of the femoral neck was 30 degrees +/- 7 degrees and 31 degrees +/- 8 degrees degrees for the right and left side, respectively. The sulcus angle was 143 degrees +/- 8 degrees and 147 degrees +/- 9 degrees, the congruence angle 7.3 degrees +/- 12 degrees and 7.1 degrees +/- 13 degrees, and the lateral patellofemoral angle 6.4 degrees +/- 8 degrees and 6.1 degrees +/- 7 degrees, respectively. There was no correlation between the degree of femoral anteversion and the indices of the patellofemoral relationships. Thus, this study indicates that there is no association between increased femoral anteversion and abnormal patellofemoral characteristics.
