Of the patients, 35 had an OCD lesion and 80 a full-thickness cartilage lesion. During a follow-up period from 2 to 13 years all treatment failures were identified. The failure rate between OCD lesions and full-thickness cartilage lesions was compared with Kaplan-Meier analysis. Patient-reported outcome was evaluated 2 years postoperatively with the Lysholm score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>During the follow-up 21 out of 115 patients encountered a treatment failure. The failure rate for full-thickness cartilage lesions was 19.1% and for OCD lesions 43.3% over the 10-year follow-up. Patient-reported outcome improved from baseline to 2 years postoperatively. The improvement from baseline was statistically significant, and the Lysholm score improved more than the minimal clinically important difference. The patient-reported outcome showed no difference between lesion types at 2 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In the presented retrospective study, the failure rate of first-generation ACI was higher in OCD lesions than in large full-thickness cartilage lesions, suggesting that OCD lesions may associate with properties that affect the durability of repair tissue. Future prospective studies are needed to tell us how to best repair OCD lesions with biological tissue engineering.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1947603520935953","type":"journal-article","created":{"date-parts":[[2020,6,30]],"date-time":"2020-06-30T06:26:59Z","timestamp":1593498419000},"page":"1105S-1112S","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Chondral and Osteochondritis Dissecans Lesions Treated by Autologous Chondrocytes Implantation: A Mid- to Long-Term Nonrandomized Comparison"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6389-051X","authenticated-orcid":false,"given":"Teemu","family":"Paatela","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Vasara","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Sormaala","sequence":"additional","affiliation":[{"name":"Department of Radiology, Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heikki","family":"Nurmi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Central Finland Central Hospital, Jyv\u00e4skyl\u00e4, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannu","family":"Kautiainen","sequence":"additional","affiliation":[{"name":"Primary Health Care Unit, Kuopio University Hospital, Kuopio, Finland"},{"name":"Folkh\u00e4lsan Research Center, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilkka","family":"Kiviranta","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Helsinki University Hospital, Helsinki, Finland"},{"name":"Department of Orthopaedics and Traumatology, University of Helsinki, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,6,30]]},"reference":[{"key":"bibr1-1947603520935953","doi-asserted-by":"publisher","DOI":"10.3109\/17453679608994664"},{"key":"bibr2-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMe020055"},{"key":"bibr3-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1177\/0363546509352157"},{"key":"bibr4-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2007.02.001"},{"issue":"1","key":"bibr5-1947603520935953","doi-asserted-by":"crossref","DOI":"10.1177\/0363546503259345","volume":"32","author":"Ar\u00f8en A","year":"2004","journal-title":"Am J Sports Med"},{"key":"bibr6-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-013-2824-y"},{"key":"bibr7-1947603520935953","doi-asserted-by":"publisher","DOI":"10.3109\/17453677608988756"},{"key":"bibr8-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2290-y"},{"key":"bibr9-1947603520935953","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200602000-00004"},{"key":"bibr10-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1126\/scitranslmed.aad8335"},{"key":"bibr11-1947603520935953","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197759060-00010"},{"key":"bibr12-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-016-2453-5"},{"key":"bibr13-1947603520935953","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-013-2837-6"},{"key":"bibr14-1947603520935953","unstructured":"American Academy of Orthopaedic Surgeons.
