Recurrences usually result from incomplete removal of the loose bodies or diseased synovium at the initial surgery. We report a patient with synovial chondromatosis localized into the Hoffa's body who presented with anterior knee pain and mechanical symptoms. At the first arthroscopy, all pathological tissue was removed. At 1\u2010year follow\u2010up, clinical and radiographic examinations were normal. Symptoms recurred at 3 years, when a bony mass in the Hoffa's body was evident on MRI. The mass was removed through a mini\u2010arthrotomy. Histology excluded malignancy. At 10\u2010year follow\u2010up, the patient remained free of symptoms. Synovial chondromatosis can occur with unusual patterns of recurrence. The growth of a large size mass confined to fat pad without intra\u2010articular involvement does not allow to exclude the diagnosis of recurrent synovial chondromatosis.<\/jats:p>","DOI":"10.1007\/s00167-009-0859-0","type":"journal-article","created":{"date-parts":[[2009,7,9]],"date-time":"2009-07-09T13:11:16Z","timestamp":1247145076000},"page":"1421-1424","source":"Crossref","is-referenced-by-count":13,"title":["Recurrence of synovial chondromatosis of the Hoffa's body"],"prefix":"10.1002","volume":"17","author":[{"given":"Leonardo","family":"Osti","sequence":"first","affiliation":[{"name":"Unit of Arthroscopy and Sports Trauma Surgery Hesperia Hospital Via Arqu\u00e0 80\/b Modena Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rocco","family":"Papalia","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery Campus Biomedico University of Rome Via Alvaro del Portillo 200 Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelo","family":"Del Buono","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery Campus Biomedico University of Rome Via Alvaro del Portillo 200 Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincenzo","family":"Denaro","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery Campus Biomedico University of Rome Via Alvaro del Portillo 200 Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola","family":"Maffulli","sequence":"additional","affiliation":[{"name":"Centre for Sports and Exercise Medicine, Barts The London School of Medicine and Dentistry Mile End Hospital 275 Bancroft Road E1 4DG London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,7,10]]},"reference":[{"key":"e_1_2_4_2_1","first-page":"216","article-title":"Synovial chondromatosis and chondrosarcoma.
