Correlation between MRI medial and lateral tibial cartilage volume measurement and actual medial cartilage volumes, using intraclass correlation power analysis. Medial cartilage volume measurement by a radiologist and the researcher correlated well with actual medial cartilage volume (intraclass correlation coefficient (ICC) = 0.98 and 0.89 in A and B, respectively). The reliability of observers was good (ICC = 0.92 in C). Lateral cartilage volume measurement by a radiologist and a researcher correlated well with actual lateral cartilage volume (ICC = 0.99 and 0.97 in D and E, respectively). The reliability of observers was excellent (ICC = 0.97 in F).
