A 65-year-old woman presented with pain in her right hip for 6 years. On examination, a swelling was palpable at the base of scarpa\u2019s triangle and her right hip movements were restricted. Imaging modalities showed ossified nodules in the antero-inferior aspect of the hip joint, joint effusion and arthritic changes. We diagnosed the patient to have synovial chondromatosis with secondary arthritis of the hip joint. We performed a total hip arthroplasty with simultaneous synovectomy and extraction of the osteochondral loose bodies, 5 of which were about 2\u00d72 cm in size. We found that excessive acetabular reaming was required due to craters, the osteochondral masses formed on the acetabular surface. Histopathological analysis confirmed the diagnosis. The patient had an excellent functional outcome and no recurrence 5 years following the surgery.<\/jats:p>","DOI":"10.1136\/bcr-2021-246039","type":"journal-article","created":{"date-parts":[[2022,1,21]],"date-time":"2022-01-21T10:21:04Z","timestamp":1642760464000},"page":"e246039","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Giant synovial chondromatosis of hip"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3621-150X","authenticated-orcid":false,"given":"Satvik N","family":"Pai","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohan M","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,1,21]]},"reference":[{"key":"2025082713042917000_15.1.e246039.1","doi-asserted-by":"crossref","first-page":"05","DOI":"10.2106\/JBJS.RVW.O.00054","article-title":"Synovial chondromatosis","volume":"4","author":"Neumann","year":"2016","journal-title":"JBJS Rev"},{"key":"2025082713042917000_15.1.e246039.2","doi-asserted-by":"crossref","DOI":"10.1186\/s12891-020-03322-1","article-title":"Bilateral synovial chondromatosis of the elbow in an adolescent: a case report and literature review","volume":"21","author":"Mo","year":"2020","journal-title":"BMC Musculoskelet Disord"},{"key":"2025082713042917000_15.1.e246039.3","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1007\/BF00203697","article-title":"Giant solitary synovial chondromatosis","volume":"23","author":"Edeiken","year":"1994","journal-title":"Skeletal Radiol"},{"key":"2025082713042917000_15.1.e246039.4","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1016\/j.jor.2019.02.010","article-title":"Synovial chondromatosis of the hip, a case report and literature review","volume":"16","author":"van der Valk","year":"2019","journal-title":"J Orthop"},{"key":"2025082713042917000_15.1.e246039.5","doi-asserted-by":"crossref","DOI":"10.1186\/s13018-020-01928-8","article-title":"Arthroscopic treatment of synovial chondromatosis of hip joint","volume":"15","author":"Liu","year":"2020","journal-title":"J Orthop Surg Res"},{"key":"2025082713042917000_15.1.e246039.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2014.05.033"},{"key":"2025082713042917000_15.1.e246039.7","doi-asserted-by":"crossref","first-page":"2173","DOI":"10.1016\/j.arth.2018.02.027","article-title":"Long-Term outcome of hip arthroplasty in the setting of synovial chondromatosis","volume":"33","author":"Tibbo","year":"2018","journal-title":"J Arthroplasty"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2021-246039","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T20:04:37Z","timestamp":1756325077000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2021-246039"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,1]]},"references-count":7,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,1,21]]},"published-print":{"date-parts":[[2022,1]]}},"alternative-id":["10.1136\/bcr-2021-246039"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2021-246039","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,1]]}}}
