The Lysholm score, International Knee Documentation Committee score, and Knee Society Score were determined. Plain radiography was used for evaluation of osteoarthritis, and magnetic resonance imaging (MRI) was used to assess the cartilage status and meniscal extrusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Thirty\u2010nine patients with a mean age of 40 \u00b1 9\u00a0years were recruited. The first visit was conducted at a mean of 13.6\u00a0months (range, 11 to 17\u00a0months) postoperatively, and the last visit was conducted at a mean of 50.4\u00a0months (range, 48 to 72\u00a0months) postoperatively. Of the patients, 29 were men. The lateral side was involved in 27 patients. The Lysholm knee score increased to a median value of 89 (range, 75 to 100) at the first visit and 88 (range, 76 to 100) at the second visit from a preoperative median value of 79 (range, 37 to 99), which was statistically significant according to the Kruskal\u2010Wallis test. According to the Kellgren\u2010Lawrence grade based on anteroposterior radiographs, 21 patients (54%) showed no arthrosis progression and the overall status of arthrosis on anteroposterior radiographs was significantly changed (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001).

The meniscal extrusion extent was 4.2 \u00b1 0.4\u00a0mm at the first visit and 4.2 \u00b1 0.6\u00a0mm at the second visit (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .678), and the relative percentage of extrusion was 0.44 \u00b1 0.16 and 0.51 \u00b1 0.21, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .059).
