On the sagittal section image following the center of the lateral femoral condyle, the weight\u2010bearing area of the articular cartilage was divided into 6 segments based on the meniscal coverage area from anterior to posterior direction. The mean T2 values of each of the 6 segments were measured for 3 regions of interest: overall, deep, and superficial layers. The change in T2 values was statistically analyzed by paired\n                      <jats:italic>t\u2010<\/jats:italic>\n                      tests.

The mean follow\u2010up period was 3.2 years (range 2.0\u20105.4 years). Among the 6 segments, the mean T2 value showed significant improvement in the overall layer of F2 (the middle weight\u2010bearing area of femoral condyle) and TP3 (the posterior weight\u2010bearing area of tibia condyle) segments (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .013 and .021, respectively) and the superficial layer of the F3 (the posterior weight\u2010bearing area of femoral condyle) segments (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .028).
