Among reported cases of knee osteochondromatosis, those originating from the anterior cruciate ligament (ACL) are very rare. We report an unusual case of primary synovial osteochondromatosis. A 27-year-old woman complained of a restricted range of right-knee motion and pain when walking. With locking symptoms similar to those associated with a meniscus bucket handle tear. Although plain radiograph and MRI showed normal appearance, diagnostic arthroscopy revealed the curious appearance of a huge mass seated on ACL. In addition, the sign of proliferation of synovium and cartilaginous tissues were apparent. The ACL mass has been removed while preserving the ACL fibres. Histological examination confirmed a diagnosis of osteochondromatosis. To the best of our knowledge, this is the first report to describe synovial osteochondromatosis originating from ACL fibres and has been resected while preserving the ACL.<\/jats:p>","DOI":"10.1136\/bcr-2012-008218","type":"journal-article","created":{"date-parts":[[2013,1,23]],"date-time":"2013-01-23T11:39:57Z","timestamp":1358941197000},"page":"bcr2012008218","source":"Crossref","is-referenced-by-count":3,"title":["Synovial osteochondroma originating from the synovium of the anterior cruciate ligament"],"prefix":"10.1136","volume":"2013","author":[{"given":"Motaz Abdulrhuman","family":"AlAqeel","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdulaziz","family":"Al-Ahaideb","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,1,23]]},"reference":[{"doi-asserted-by":"publisher","key":"2025042701422359000_2013.jan23_1.bcr2012008218.1","DOI":"10.1080\/13577140310001607293"},{"doi-asserted-by":"publisher","key":"2025042701422359000_2013.jan23_1.bcr2012008218.2","DOI":"10.1097\/00003086-200301000-00009"},{"key":"2025042701422359000_2013.jan23_1.bcr2012008218.3","doi-asserted-by":"crossref","first-page":"166","DOI":"10.1016\/S0749-8063(05)80088-X","article-title":"Generalized synovial chondromatosis of the knee: a comparison of removal of the loose bodies alone with arthroscopic synovectomy","volume":"10","author":"Ogilvie-Harris","year":"1994","journal-title":"Arthroscopy"},{"key":"2025042701422359000_2013.jan23_1.bcr2012008218.4","doi-asserted-by":"crossref","first-page":"530","DOI":"10.1302\/0301-620X.49B3.530","article-title":"Synovial chondromatosis","volume":"49","author":"Jeffreys","year":"1967","journal-title":"J Bone Joint Surg Br"},{"key":"2025042701422359000_2013.jan23_1.bcr2012008218.5","doi-asserted-by":"crossref","first-page":"807","DOI":"10.1302\/0301-620X.70B5.3192585","article-title":"Synovial chondromatosis","volume":"70","author":"Maurice","year":"1988","journal-title":"J Bone Joint Surg Br"},{"doi-asserted-by":"publisher","key":"2025042701422359000_2013.jan23_1.bcr2012008218.6","DOI":"10.1016\/S0749-8063(98)70062-3"},{"doi-asserted-by":"publisher","key":"2025042701422359000_2013.jan23_1.bcr2012008218.7","DOI":"10.1007\/s00167-007-0292-1"},{"doi-asserted-by":"publisher","key":"2025042701422359000_2013.jan23_1.bcr2012008218.8","DOI":"10.1186\/1758-2555-1-6"},{"doi-asserted-by":"publisher","key":"2025042701422359000_2013.jan23_1.bcr2012008218.9","DOI":"10.1046\/j.1365-2613.2000.00154.x"},{"key":"2025042701422359000_2013.jan23_1.bcr2012008218.10","doi-asserted-by":"crossref","first-page":"136","DOI":"10.3928\/01477447-20101221-26","article-title":"A synovial osteochondroma replacing the anterior cruciate ligament at the intercondylar notch","volume":"34","author":"Chung","year":"2011","journal-title":"Orthopedics"},{"doi-asserted-by":"publisher","key":"2025042701422359000_2013.jan23_1.bcr2012008218.11","DOI":"10.1016\/j.knee.2006.09.005"},{"key":"2025042701422359000_2013.jan23_1.bcr2012008218.12","doi-asserted-by":"crossref","first-page":"803","DOI":"10.1016\/j.arthro.2005.06.024","article-title":"Primary synovial chondromatosis mimicking medial meniscal tear in a young man","volume":"22","author":"Lin","year":"2006","journal-title":"Arthroscopy"},{"key":"2025042701422359000_2013.jan23_1.bcr2012008218.13","doi-asserted-by":"crossref","first-page":"792","DOI":"10.2106\/00004623-197759060-00013","article-title":"Synovial osteochondromatosis: a histopathological study of thirty cases","volume":"59","author":"Milgram","year":"1977","journal-title":"J Bone Joint Surg Am"},{"key":"2025042701422359000_2013.jan23_1.bcr2012008218.14","first-page":"151","article-title":"Synovial chondrometaplasia: review of world literature and a study of 18 Canadian cases","volume":"9","author":"Trias","year":"1976","journal-title":"Can J Surg"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2012-008218","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T08:42:32Z","timestamp":1745743352000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2012-008218"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,1,23]]},"references-count":14,"alternative-id":["10.1136\/bcr-2012-008218"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2012-008218","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2013,1,23]]}}}
