The return\u2010to\u2010sport rate ranged from 75% to 82%. For patient\u2010reported outcomes, the Knee Injury and Osteoarthritis Score Sport increased in 4 studies, the Tegner activity scale score increased in 3 studies but decreased in 1, and the Marx activity scale score increased in 1 study but decreased in 2. Studies reporting improvements in the Cincinnati Knee Score and Knee Injury and Osteoarthritis Score Sport reached the minimal clinically important difference. The reoperation rate was high (ranging from 34% to 53% in more than half of studies), with reoperations primarily performed for loose body removal or debridement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This systematic review of 13 studies suggests that OCA transplantation for cartilage defects allows most athletes to return to sport (range, 75%\u201082%). Most studies reported improvements in sports\u2010specific patient\u2010reported outcomes at follow\u2010up and reached the minimal clinically important difference. However, the reoperation rate was high in several studies, with a large percentage of patients requiring loose body removal or debridement. The long\u2010term survival of the allografts is largely unknown, but this study suggests OCA transplantation consistently improves function in athletes with chondral injuries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Level IV, systematic review of Level III and IV studies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2018.11.064","type":"journal-article","created":{"date-parts":[[2019,4,30]],"date-time":"2019-04-30T17:33:45Z","timestamp":1556645625000},"page":"1880-1889","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":56,"title":["Return to Sport and Sports\u2010Specific Outcomes After Osteochondral Allograft Transplantation in the Knee: A Systematic Review of Studies With at Least 2\u00a0Years' Mean Follow\u2010Up"],"prefix":"10.1002","volume":"35","author":[{"given":"Zachary T.","family":"Crawford","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Sports Medicine University of Cincinnati Cincinnati Ohio U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam P.","family":"Schumaier","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Sports Medicine University of Cincinnati Cincinnati Ohio U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgina","family":"Glogovac","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Sports Medicine University of Cincinnati Cincinnati Ohio U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian M.","family":"Grawe","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Sports Medicine University of Cincinnati Cincinnati Ohio U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,4,30]]},"reference":[{"key":"e_1_2_2_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/1947603513481603"},{"key":"e_1_2_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546509351650"},{"key":"e_1_2_2_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506288240"},{"key":"e_1_2_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(97)90124-9"},{"key":"e_1_2_2_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-016-4262-3"},{"key":"e_1_2_2_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546517694857"},{"key":"e_1_2_2_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-015-3509-8"},{"key":"e_1_2_2_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-009-0765-5"},{"key":"e_1_2_2_10_2","doi-asserted-by":"publisher","DOI":"10.3928\/01477447-20111122-07"},{"key":"e_1_2_2_11_2","doi-asserted-by":"publisher","DOI":"10.1177\/1947603514566298"},{"key":"e_1_2_2_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-015-9298-3"},{"key":"e_1_2_2_13_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546511435780"},{"key":"e_1_2_2_14_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546514565770"},{"key":"e_1_2_2_15_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546517699846"},{"key":"e_1_2_2_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546507299932"},{"key":"e_1_2_2_17_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1445-2197.2003.02748.x"},{"key":"e_1_2_2_18_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2523-0"},{"key":"e_1_2_2_19_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.16.01542"},{"key":"e_1_2_2_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2004.12.008"},{"key":"e_1_2_2_21_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546516676072"},{"key":"e_1_2_2_22_2","first-page":"244","article-title":"Outcomes following structural grafting of distal femoral osteochondral injuries in patients aged 40 years and older","volume":"30","author":"Degen R.M.","year":"2017","journal-title":"J\u00a0Knee Surg"},{"key":"e_1_2_2_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2013.05.021"},{"key":"e_1_2_2_24_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506295178"},{"key":"e_1_2_2_25_2","doi-asserted-by":"publisher","DOI":"10.1177\/1947603515595072"},{"key":"e_1_2_2_26_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-013-2388-0"},{"key":"e_1_2_2_27_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.H.00703"},{"key":"e_1_2_2_28_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546509354163"},{"key":"e_1_2_2_29_2","article-title":"Minimal clinically important differences and substantial clinical benefit in patient\u2010reported outcome measures after autologous chondrocyte implantation","author":"Ogura T.","year":"2018","journal-title":"Cartilage."},{"key":"e_1_2_2_30_2","unstructured":"J.Irrgang.Summary of clinical outcome measures for sports\u2010related knee injuries Published June 2012.
