The MRI findings at 12 months after the surgery were assessed by the modified magnetic resonance observation of cartilage repair tissue (MOCART) score to determine the degree of bone marrow edema (BME), plug union, and plug necrosis. The clinical outcomes were assessed by Lysholm score to clarify the minimal clinically important difference (MCID) and patient acceptable symptom state analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In total, 58 patients (17 men and 41 women) were enrolled in this study. Among them, 30 knees were treated by MOS alone and 28 knees were treated by MOS with HTO. The MOCART scores of patients who received MOS alone were significantly lower in BME score (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .0060), plug union score (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .0216), and in plug necrosis score (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .0326) than patients who received MOS with HTO.

Female and older patients had better resolution of BME, but there was no significant correlation between MRI findings and the postoperative Lysholm score.
