The proposed system of healing classification demonstrated good inter- and intraobserver reliability. Healing patterns were not significantly associated with any particular age, sex, lesion location, treatment type, or physeal patency status. The development of a classification system for knee OCD may eventually improve clinical assessment and management of OCD lesions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2325967117740846","type":"journal-article","created":{"date-parts":[[2017,12,1]],"date-time":"2017-12-01T04:00:52Z","timestamp":1512100852000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["A Radiographic Healing Classification for Osteochondritis Dissecans of the Knee Provides Good Interobserver Reliability"],"prefix":"10.1177","volume":"5","author":[{"given":"David E.","family":"Ramski","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, The Children\u2019s Hospital of Philadelphia, Philadelphia, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theodore J.","family":"Ganley","sequence":"additional","affiliation":[{"name":"Sports Medicine and Performance Center, The Children\u2019s Hospital of Philadelphia, Philadelphia, Pennsylvania, USA."},{"name":"Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James L.","family":"Carey","sequence":"additional","affiliation":[{"name":"Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania, USA."},{"name":"Penn Center for Cartilage Repair and Osteochondritis Dissecans Treatment, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,12]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2008.09.008"},{"key":"e_1_3_2_3_2","volume-title":"Practical Statistics for Medical Research","author":"Altman D","year":"1991","unstructured":"Altman D.
