The inclusion criteria were AOG only without osteotomy, operative ages between 60 and 79 years, &gt;2 years of follow\u2010up, and involved femorotibial angle between 169\u00b0 and 179\u00b0 (normal alignment). Patients who underwent osteotomy to improve knee alignment and patients with inflammatory diseases such as rheumatoid arthritis were excluded. The patients\u2019 knee symptoms and their clinical outcome were evaluated according to the criteria of the knee scoring system of the Japanese Orthopedic Association (JOA), International Knee Documentation Committee (IKDC) subjective score, and the ability of straight sitting in Japanese style.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This study enrolled 57 cases and 60 knee joints during the study period. The follow\u2010up ratio was 85.1%. Moreover, 14 men and 43 women and 29 right and 31 left knee joints were included in this study. The mean operative age and mean follow\u2010up period were 67.8 years (range 60\u201076 years) and 81.1 months (range 24\u2010167 months), respectively. In addition, the study involved 30 cases and 32 knee joints (60s group), and 27 cases and 28 knee joints (70s group). Moreover, 34 cases and 36 knee joints had osteonecrosis (ON group), and 23 cases and 24 knee joints had cartilage injury (CI group). The IKDC subjective and JOA scores in both the 60s and 70s groups showed significant differences: 2 years after AOG \uff1eat the follow\u2010up period, \uff1eat the preoperative period. The scores in both the CI and ON groups showed similar significant differences. Furthermore, 8.3% and 53.5% of the patients could sit straight in Japanese style at the preoperative period and 2 years after AOG, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Even if the patient\u2019s operative age was &gt;60 years, the AOG only for their knee osteochondral diseases had good clinical outcomes, including the ability to sit straight in Japanese style.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Level IV, Therapeutic case series Key words: autologous osteochondral grafts, aged patients, clinical outcome, knee joint, straight sitting in Japanese style<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.asmr.2023.100774","type":"journal-article","created":{"date-parts":[[2023,7,27]],"date-time":"2023-07-27T11:36:57Z","timestamp":1690457817000},"update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":4,"title":["Autologous Osteochondral Grafts for Knee Osteochondral Diseases Result in Good Patient\u2010Reported Outcomes in Patients Older Than 60 Years"],"prefix":"10.1002","volume":"5","author":[{"given":"Yasuaki","family":"Nakagawa","sequence":"first","affiliation":[{"name":"Clinical Research Center National Hospital Organization Kyoto Medical Center Kyoto Japan"},{"name":"Department of Orthopaedic Surgery Japan Baptist Medical Foundation Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shogo","family":"Mukai","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery National Hospital Organization Kyoto Medical Center Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Satomi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery National Hospital Organization Kyoto Medical Center Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuki","family":"Shinya","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery National Hospital Organization Kyoto Medical Center Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryota","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery National Hospital Organization Kyoto Medical Center Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Motoi","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery National Hospital Organization Kyoto Medical Center Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,7,26]]},"reference":[{"key":"e_1_2_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01466630"},{"key":"e_1_2_2_3_2","doi-asserted-by":"publisher","DOI":"10.3928\/0147-7447-19980701-04"},{"key":"e_1_2_2_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200208000-00020"},{"key":"e_1_2_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(05)80428-1"},{"key":"e_1_2_2_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/03635465010290052001"},{"key":"e_1_2_2_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198512000-00007"},{"issue":"1","key":"e_1_2_2_8_2","doi-asserted-by":"crossref","first-page":"E5","DOI":"10.1053\/jars.2002.29930","article-title":"A\u00a0novel surgical procedure for osteochondritis dissecans of the lateral femoral condyle: Exchanging osteochondral plugs taken from donor and recipient sites: A case report and review of the literature","volume":"18","author":"Nakagawa Y.","year":"2002","journal-title":"Arthroscopy"},{"key":"e_1_2_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)14031-7"},{"key":"e_1_2_2_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546509360405"},{"key":"e_1_2_2_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2013.01.001"},{"key":"e_1_2_2_12_2","doi-asserted-by":"publisher","DOI":"10.1080\/17453674.2016.1265877"},{"key":"e_1_2_2_13_2","first-page":"643","article-title":"Survival of autologous osteochondral grafts in the knee and factors influencing outcome","volume":"78","author":"Robb C.A.","year":"2012","journal-title":"Acta Orthop Belg"},{"key":"e_1_2_2_14_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546516634299"},{"key":"e_1_2_2_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00776-014-0633-0"},{"key":"e_1_2_2_16_2","unstructured":"Brittberg M Aglietti A Gambardella R et al.
