BACKGROUND High tibial osteotomy(HTO)is a well-established method for the treatment of medial compartment osteoarthritis of the knee with varus ***,HTO alone cannot adequately repair the arthritic joint,necessitating cartilage regeneration *** regeneration procedures with concomitant HTO are used to improve the clinical outcome in patients with varus *** To evaluate cartilage regeneration after implantation of allogenic human umbilical cord blood-derived mesenchymal stem cells(hUCB-MSCs)with concomitant *** Data for patients who underwent implantation of hUCB-MSCs with concomitant HTO were *** patients included in this study were over 40 years old,had a varus deformity of more than 5°,and a full-thickness International Cartilage Repair Society(ICRS)grade IV articular cartilage lesion of more than 4 cm2 in the medial compartment of the *** patients underwent second-look arthroscopy during hardware *** regeneration was evaluated macroscopically using the ICRS grading system in second-look *** also assessed the effects of patient characteristics,such as trochlear lesions,age,and lesion size,using patient medical *** A total of 125 patients were included in the study,with an average age of 58.3±6.8 years(range:43-74 years old);95(76%)were female and 30(24%)were *** average hip-knee-ankle(HKA)angle for measuring varus deformity was 7.6°±2.4°(range:5.0-14.2°).In second-look arthroscopy,the status of medial femoral condyle(MFC)cartilage was as follows:73(58.4%)patients with ICRS grade I,37(29.6%)with ICRS grade II,and 15(12%)with ICRS grade *** patients were staged with ICRS grade ***,the scores[except International Knee Documentation Committee(IKDC)at 1 year]of the ICRS grade I group improved more significantly than those of the ICRS grade II and III *** Implantation of hUCB-MSCs with concomitant HTO is an effective treatment for patients wit
