We present a case of a 53-year-old female avid runner with left hip pain. Clinical evaluation and X-ray imaging led to a diagnosis of calcific tendinopathy of the rectus femoris tendon. The patient was treated conservatively with non-steroidal anti-inflammatory drugs, physical therapy and rest. Calcific tendinopathy of the rectus femoris tendon can occur rarely in active patients and may be a cause of hip pain, responsive to conservative management, but with other treatment options possible if recalcitrant.<\/jats:p>","DOI":"10.1136\/bcr-2020-236809","type":"journal-article","created":{"date-parts":[[2020,12,13]],"date-time":"2020-12-13T23:30:27Z","timestamp":1607902227000},"page":"e236809","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Rare case of symptomatic calcific tendinopathy of the origin of rectus femoris tendon"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8701-4581","authenticated-orcid":false,"given":"Tarang","family":"Jethwa","sequence":"first","affiliation":[{"name":"Family Medicine, Mayo Clinic Florida, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andre","family":"Abadin","sequence":"additional","affiliation":[{"name":"Family Medicine, Mayo Clinic Florida, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7537-7457","authenticated-orcid":false,"given":"George","family":"Pujalte","sequence":"additional","affiliation":[{"name":"Family Medicine, Mayo Clinic Florida, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,12,13]]},"reference":[{"key":"2025082707145409000_13.12.e236809.1","first-page":"32","article-title":"Acute calcific tendinitis of the rectus femoris: a case series","volume":"5","author":"IKobayashi","year":"2015","journal-title":"J Orthop Case Rep"},{"key":"2025082707145409000_13.12.e236809.2","first-page":"110","article-title":"Calcific tendonitis of the rectus femoris","volume":"9","author":"King","year":"1967","journal-title":"Am J Orthop"},{"key":"2025082707145409000_13.12.e236809.3","doi-asserted-by":"publisher","DOI":"10.3928\/01477447-20090527-13"},{"key":"2025082707145409000_13.12.e236809.4","article-title":"Rectus femoris tendon calcification: arthroscopic excision in 6 top amateur athletes","volume":"2","author":"Zini","year":"2014","journal-title":"Orthop J Sports Med"},{"key":"2025082707145409000_13.12.e236809.5","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-009-1208-9"},{"key":"2025082707145409000_13.12.e236809.6","doi-asserted-by":"crossref","first-page":"3772","DOI":"10.12998\/wjcc.v7.i22.3772","article-title":"Ultrasonographic evaluation of the effect of extracorporeal shock wave therapy on calcific tendinopathy of the rectus femoris tendon: a case report","volume":"7","author":"Lee","year":"2019","journal-title":"World J Clin Cases"},{"key":"2025082707145409000_13.12.e236809.7","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1055\/s-0029-1245333","article-title":"US-guided therapy of calcific tendinopathy: clinical and radiological outcome assessment in shoulder and non-shoulder tendons","volume":"32","author":"De Zordo","year":"2011","journal-title":"Ultraschall Med"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2020-236809","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T14:15:04Z","timestamp":1756304104000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2020-236809"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,12]]},"references-count":7,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2020,12,13]]},"published-print":{"date-parts":[[2020,12]]}},"alternative-id":["10.1136\/bcr-2020-236809"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2020-236809","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2020,12]]}}}
