Abstract Background This study aimed to introduce the medulloscopy-assisted autologous bone graft for osteonecrosis of the knee following adolescent leukemia treatment and to report the mid-term clinical and radiological results. Materials and Methods We retrospectively reviewed records of eight consecutive knees in six patients with extensive osteonecrosis of the distal femoral condyles, from 2013 to 2015. All patients were treated with autologous bone grafts using medulloscopy. We evaluated functional and objective Knee Society Score (KSS) pre- and postoperatively. Clinical and radiological outcomes were evaluated at the last follow-up. Results The mean age of the patients at the time of surgery was 21.5 years. The mean follow-up period was 45 months. No additional surgery was required during the follow-up period. The mean objective KSS significantly increased from 60.6 points (range 55–65) to 90.0 points (range 70–95), postoperatively (p
