However, vascular causes, such as genicular artery pseudoaneurysm, are rare and may be overlooked, especially when symptoms persist despite appropriate treatment.\n\nCase Report: We describe a 60-year-old male with multiple comorbidities who presented with recurrent painful swelling of the right knee. Initial evaluations identified sequential pathologies, including popliteal DVT, ruptured Baker\u2019s cyst, and septic arthritis, all treated appropriately. Despite resolution of infection and withdrawal of anticoagulation, hemarthrosis recurred. Further evaluation with Doppler ultrasonography and magnetic resonance angiography revealed a pseudoaneurysm of the superior medial genicular artery. The lesion was successfully treated using ultrasound-guided compression, resulting in complete thrombosis and resolution of symptoms without complications.\n\nConclusion: Superior medial genicular artery pseudoaneurysm is a rare but important cause of recurrent hemarthrosis. Persistent or unexplained knee swelling should prompt early vascular imaging to avoid diagnostic delay and enable timely, minimally invasive management.\n\nKeywords: Pseudoaneurysm, genicular artery, recurrent knee swelling, hemarthrosis, ultrasound-guided compression.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i04.7092","type":"journal-article","created":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T05:33:38Z","timestamp":1775712818000},"page":"210-215","source":"Crossref","is-referenced-by-count":0,"title":["Pseudoaneurysm of the Medial Genicular Artery as a Rare Cause of Recurrent Knee Swelling \u2013 A Case Report"],"prefix":"10.13107","volume":"16","author":[{"given":"Ajayakumar","family":"Thankappan","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Apollo Adlux Hospital, Kochi, Kerala, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nizaj","family":"Nasimudeen","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Apollo Adlux Hospital, Kochi, Kerala, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramjith","family":"Sivanandan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Apollo Adlux Hospital, Kochi, Kerala, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jimmy Joseph","family":"Meleppuram","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Apollo Adlux Hospital, Kochi, Kerala, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kumar","family":"Muthukumar","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, Apollo Adlux Hospital, Kochi, Kerala, India."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prince Shanavas","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Apollo Adlux Hospital, Kochi, Kerala, India,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T05:33:40Z","timestamp":1775712820000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/04\/pseudoaneurysm-of-the-medial-genicular-artery-as-a-rare-cause-of-recurrent-knee-swelling-a-case-report\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i04.7092","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
