Abstract

0OBJECTIVE: To investigate the mean values and correlations between the rotational profiles of bilateral lower extremities in Korean elderly men. METHOD: 100 lower extremities were examined for the rotational profiles of bilateral lower extremities with radiographic examination.
RESULTS
The mean values of femoral anteversion, axial rotation of the knee joint, proximal and distal tibial torsion, bimalleolar axis (BMA), and Q angle were 8.72degrees, 0.19degrees, 34.53degrees, 26.25degrees, 20.97degrees, 5.65degrees. In Korean elderly men, the result of tibial torsion and Q angle was smaller than the results of other studies, and the bilateral differences were detected in the measured profiles of lower extremities, except axial rotation of the knee joint. However, all profiles represented a positive correlation between right and left lower extremities. The correlation between proximal tibial torsion and BMA had a positive correlation, But the femoral anteversion and tibial torsion had no correlations among the profiles in Korean elderly men.
CONCLUSION
We suspected that Korean elderly healthy men have reduced tibial torsion and more genu varus alignment, and the rotational profiles of lower extremities showed side to side difference, but there were symmetrical tendency. It will be helpful in assessing the evaluation, treating, researching of the musculoskeletal problem in Korean elderly people.
