Abstract

INTRODUCTION: The knee joint stands out as a structure that is commonly affected by degenerative alterations, injuries and syndromes. Precise objective clinical evaluations are necessary for establishing appropriate diagnoses and, consequently, better results from both surgical procedures and rehabilitation programs. OBJECTIVE: To investigate the existence of differences between the knees during gait and their relationship with the static difference in the sagittal and frontal planes. METHOD: Forty-five healthy subjects were included, of whom 21 were male and 24 were female. Knee joint range of motion was measured during gait by means of flexible electrogoniometry. The static posture of the knee was evaluated by means of photogrammetry. The data were analyzed descriptively and the Pearson correlation coefficient was applied. RESULTS: The individuals presented mean values that were similar for right and left knees in static recordings of the sagittal and frontal planes (difference of approximately 0.5º). However, the standard deviation was large, thus indicating great variability between the subjects. For the dynamic recordings, the difference between the knees was 0.4º for the sagittal plane and 1º for the frontal plane. The variability found was also large, especially for the frontal plane. There was no correlation between the static and dynamic recordings in the two planes of motion evaluated (r = -0.003 and p = 0.492 for the sagittal plane; r = -0.014 and p = 0.465 for the frontal plane). CONCLUSION: Although no relationship was found between the static and dynamic recordings, this matter deserves investigation in future studies, with evaluations of broader groups with specific and more pronounced postural abnormalities.
