Patients were divided into group I (isolated PTO), group P (PTO with MMPRR using the pull\u2010out technique), and group F (PTO and MMPRR using the side\u2010to\u2010side repair method). The subjective knee scores were assessed. Radiologic evaluation was based on the Kellgren\u2013Lawrence grade. Healing of medial meniscal posterior root tears (good\/loose\/scar tissue\/failed) and cartilage regeneration (excellent\/good\/poor) were assessed by arthroscopic examination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Mean clinical follow\u2010up duration of group I (n\u00a0= 22), P (n\u00a0= 25), and F (n\u00a0= 24) was 28.5 \u00b1 5.7, 27.9 \u00b1 6.2, and 26.3 \u00b1 5.3 months, respectively. At final follow\u2010up, Lysholm score, International Knee Documentation Committee subjective score, and Tegner activity scale significantly improved in all groups (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001), and subjective scores did not differ among the groups.
