Although the pathologic process for this condition remains poorly understood, histologic studies suggest vascular insufficiency of the subchondral bone may be the underlying cause for focal necrosis and subsequent compromise of the overlying articular cartilage. These lesions most commonly affect the medial femoral condyle and can be found along the margins of the intercondylar notch. Because of significant bone involvement, osteochondral allograft (OCA) transplantation has emerged as a dominant treatment option for OCD lesions because it can accurately restore the entire osteochondral unit. Given the characteristic location and large, irregular shapes of these lesions, surgical management can be challenging. These lesions are often uncontained along the periphery of the condyle, which can compromise OCA graft fixation and healing. We describe our preferred technique for the treatment of large, uncontained OCD lesions of the medial femoral condyle using a unicompartmental OCA augmented with screw fixation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Technique Video<\/jats:title>\n                    <jats:p>\n                      <jats:boxed-text content-type=\"video\" position=\"anchor\">\n                        <jats:graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" position=\"anchor\" xlink:href=\"urn:x-wiley:22126287:media:atn2bf03674:atn2bf03674-vimg-mmc1\">\n                          <jats:alt-text>video<\/jats:alt-text>\n                        <\/jats:graphic>\n                      <\/jats:boxed-text>\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>See video under supplementary data.<\/jats:bold>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.eats.2018.10.023","type":"journal-article","created":{"date-parts":[[2019,2,11]],"date-time":"2019-02-11T03:32:35Z","timestamp":1549855955000},"update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":14,"title":["Fresh Osteochondral Allograft Transplantation for Uncontained, Elongated Osteochondritis Dissecans Lesions of the Medial Femoral Condyle"],"prefix":"10.1002","volume":"8","author":[{"given":"Kristofer J.","family":"Jones","sequence":"first","affiliation":[{"name":"Division of Sports Medicine and Shoulder Surgery Department of Orthopaedic Surgery David Geffen School of Medicine at UCLA Los Angeles California U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian M.","family":"Cash","sequence":"additional","affiliation":[{"name":"Division of Sports Medicine and Shoulder Surgery Department of Orthopaedic Surgery David Geffen School of Medicine at UCLA Los Angeles California U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Armin","family":"Arshi","sequence":"additional","affiliation":[{"name":"Division of Sports Medicine and Shoulder Surgery Department of Orthopaedic Surgery David Geffen School of Medicine at UCLA Los Angeles California U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"III","given":"Riley J.","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Sports Medicine and Shoulder Service Hospital for Special Surgery New York New York U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,2,11]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2017.10.043"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546516657526"},{"key":"e_1_2_2_4_1","article-title":"Osteochondritis dissecans of the knee: Etiology and pathogenetic mechanisms.
