Trillat, the double patella is an uncommon clinical feature following repetitive injuries of the extensor mechanism of the knee. The first injury is a tendo\u2010periosteal avulsion of the suprapatellar or, less frequently, infrapatellar tendon from the corresponding patellar pole. Often these avulsions are misdiagnosed and therefore treated only with a cast or no immobilization at all. Subsequent giving\u2010way episodes lead to extensive ossification which is adjacent to or separated from the patella. The peculiar shape of this ossification overriding or underlying the primary kneecap justifies the denomination of double patella. Surgical treatment consists of removal of the calcification and reattachment of the tendon to the patella by transosseous sutures.<\/jats:p>","DOI":"10.1007\/bf01553521","type":"journal-article","created":{"date-parts":[[2005,4,27]],"date-time":"2005-04-27T15:51:35Z","timestamp":1114617095000},"page":"21-25","source":"Crossref","is-referenced-by-count":9,"title":["The double patella syndrome"],"prefix":"10.1002","volume":"3","author":[{"given":"M.","family":"Cipolla","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Clinica Valle Giulia Via de Notaris 2b I\u201000197 Rome Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Cerullo","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Clinica Valle Giulia Via de Notaris 2b I\u201000197 Rome Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Franco","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Clinica Valle Giulia Via de Notaris 2b I\u201000197 Rome Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Giann\u00ed","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Clinica Valle Giulia Via de Notaris 2b I\u201000197 Rome Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Puddu","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Clinica Valle Giulia Via de Notaris 2b I\u201000197 Rome Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[1995,3]]},"reference":[{"key":"e_1_2_1_2_2","volume-title":"La patologia del legamento crociato anteriore, Chapter 25","author":"Cipolla M","year":"1994"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.61B2.438267"},{"key":"e_1_2_1_4_2","volume-title":"Chirurgie du genu","author":"Trillat A","year":"1976"}],"container-title":["Knee Surgery, Sports Traumatology, Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/BF01553521.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/article\/10.1007\/BF01553521\/fulltext.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1007\/BF01553521","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T09:15:09Z","timestamp":1760865309000},"score":1,"resource":{"primary":{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/10.1007\/BF01553521"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1995,3]]},"references-count":3,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1995,3]]}},"alternative-id":["10.1007\/BF01553521"],"URL":"https:\/\/doi.org\/10.1007\/bf01553521","archive":["Portico"],"relation":{},"ISSN":["0942-2056","1433-7347"],"issn-type":[{"value":"0942-2056","type":"print"},{"value":"1433-7347","type":"electronic"}],"subject":[],"published":{"date-parts":[[1995,3]]}}}
