The influences of walking, running and stair activity on knee articular cartilage: Quantitative MRI using T1 rho and T2 mapping.

ABSTRACT:

Objective

To explore the different influences of walking, running and stair activity on knee articular cartilage with T1 rho and T2 mapping sequences.

Materials and methods

MRI (3.0-T) scans of the right knee were performed in twenty-three young healthy adults immediately after 30 minutes of rest, walking, running and stair activity respectively. Articular cartilage was quantitatively assessed based on T1 rho and T2 relaxation times. Analysis of variance for random block design data, bonferroni test and paired samples t tests were performed to estimate the different influences of physiological activities on articular cartilage.

Results

T1 rho and T2 values had reductions after physiological activities in all regions of articular cartilage. T1 rho and T2 values were de
