He underwent arthroscopic fixation of the defect, and during the surgery, a blunt trocar was used to localize the lesion. The trocar created a transient dimpling effect on the cartilage overlying the osteochondral defect that resembled the surface of a golf ball. This \u201cgolf ball sign\u201d then served as a visual guide during placement of a chondral dart. When present, it is believed that this sign can benefit arthroscopists by helping to improve intraoperative localization of an osteochondral defect.<\/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:atn2bf00738:atn2bf00738-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.2014.02.002","type":"journal-article","created":{"date-parts":[[2014,5,19]],"date-time":"2014-05-19T07:15:08Z","timestamp":1400483708000},"source":"Crossref","is-referenced-by-count":0,"title":["The Golf Ball Sign: Arthroscopic Localization of an Osteochondritis Dissecans Lesion of the Knee"],"prefix":"10.1002","volume":"3","author":[{"given":"Jonathan","family":"Piposar","sequence":"first","affiliation":[{"name":"Department of Orthopaedics &amp; Rehabilitation Yale University School of Medicine New Haven Connecticut U.S.A"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karen","family":"Sutton","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics &amp; Rehabilitation Yale University School of Medicine New Haven Connecticut U.S.A"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,5,19]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-009-0898-6"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546513496049"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.K.00275"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/BPO.0b013e31823d8312"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506290127"}],"container-title":["Arthroscopy Techniques"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S221262871400019X?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S221262871400019X?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.eats.2014.02.002","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/full-xml\/10.1016\/j.eats.2014.02.002","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.eats.2014.02.002","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T10:11:25Z","timestamp":1775556685000},"score":1,"resource":{"primary":{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/10.1016\/j.eats.2014.02.002"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,5,19]]},"references-count":5,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2014,6]]}},"alternative-id":["10.1016\/j.eats.2014.02.002"],"URL":"https:\/\/doi.org\/10.1016\/j.eats.2014.02.002","archive":["Portico"],"relation":{},"ISSN":["2212-6287","2212-6287"],"issn-type":[{"value":"2212-6287","type":"print"},{"value":"2212-6287","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,5,19]]}}}
