The hypothesis was that this procedure would yield good clinical outcome results and structural healing in middle\u2010 and older\u2010aged patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective study evaluating patients who had undergone MMPRT repair by suturing the meniscal root directly to the capsule, rather than by the transtibial technique, between 2013 and 2016. This all\u2010inside repair technique was performed for patients with type II MMPRTs who were over 40 years old. Exclusion criteria included tibial osteotomy due to malalignment, concomitant multiple\u2010ligament injuries and follow\u2010up time less than 2 years. The Lysholm score, Tegner activity score and International Knee Documentation Committee (IKDC) score were evaluated preoperatively and at the final follow\u2010up. Medial meniscal extrusion, the International Cartilage Repair Society (ICRS) grades of the medial compartment, and the healing status of the medial meniscus root were assessed on magnetic resonance imaging preoperatively and at the final follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty\u2010nine patients (mean age 61.7\u2009\u00b1\u20097.9) were included; the mean follow\u2010up duration was 46.2\u2009\u00b1\u20097.9\u00a0months. The mean Lysholm score significantly improved from 33.7\u2009\u00b1\u200920.9 preoperatively to 81.7\u2009\u00b1\u200919.9 at the final follow\u2010up (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), the median Tegner activity score improved from 1.0 (range 1\u20134) to 3.0 (range 2\u20134, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), and the mean IKDC score improved from 20.1\u2009\u00b1\u200916.4 to 69.6\u2009\u00b1\u200916.2 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). On MRI, 9 (31%) cases had complete healing; 17 (59%) had partial healing; and 3 (10%) had failed healing (ICCs\u2009\u2265\u20090.92). Mean meniscal extrusion significantly increased from 2.3\u2009\u00b1\u20091.7\u00a0mm preoperatively to 3.5\u2009\u00b1\u20091.5\u00a0mm postoperatively (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001, ICCs\u2009\u2265\u20090.92).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Non\u2010anatomic arthroscopic all\u2010inside repair of MMPRTs to the posterior capsule yielded good to excellent clinical results and a high rate of healing in the medial meniscus root on MRI in middle\u2010aged and older patients at short\u2010 to mid\u2010term follow\u2010up, despite increased meniscal extrusion. This method is an alternative to the transtibial pullout repair technique for treating MMPRTs in middle\u2010 and older\u2010aged patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
