On examination, she was found to have a mass at the medial patellofemoral joint line. Arthroscopy showed this to be a vascular synovial tumor extending into the medial patellofemoral joint and causing lateral deviation of the patella. The mass was resected with resolution of her symptoms and histologic examination showed this to be pigmented villonodular synovitis. There are an increasing number of case reports of these lesions causing varying mechanical symptoms in the knee and they should be considered as a differential diagnosis.<\/jats:p>","DOI":"10.1053\/jars.2000.4822","type":"journal-article","created":{"date-parts":[[2005,2,10]],"date-time":"2005-02-10T03:51:33Z","timestamp":1108007493000},"page":"767-769","source":"Crossref","is-referenced-by-count":9,"title":["Localized pigmented villonodular synovitis presenting as recurrent dislocation of the patella"],"prefix":"10.1002","volume":"16","author":[{"given":"Matthew J.","family":"Bartlett","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedics Chelsea and Westminster Hospital London England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathon","family":"Lavelle","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedics Chelsea and Westminster Hospital London England"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2000,10,1]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(05)80119-7"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199403000-00024"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199110000-00030"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(97)90134-1"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(05)80412-8"},{"key":"e_1_2_2_7_1","first-page":"281","article-title":"Mechanical symptoms arising from synovial pathology in the knee joint","volume":"20","author":"Stother IG","year":"1991","journal-title":"Ann Acad Med Singapore"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(88)80079-3"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.67B4.4030851"},{"key":"e_1_2_2_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(89)90154-0"}],"container-title":["Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0749806300418864?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0749806300418864?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1053\/jars.2000.4822","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/full-xml\/10.1053\/jars.2000.4822","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1053\/jars.2000.4822","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T08:47:14Z","timestamp":1778748434000},"score":1,"resource":{"primary":{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/10.1053\/jars.2000.4822"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,10]]},"references-count":9,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2000,10]]}},"alternative-id":["10.1053\/jars.2000.4822"],"URL":"https:\/\/doi.org\/10.1053\/jars.2000.4822","archive":["Portico"],"relation":{},"ISSN":["0749-8063","1526-3231"],"issn-type":[{"value":"0749-8063","type":"print"},{"value":"1526-3231","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,10]]}}}
