Intraoperatively, it may mimic pigmented villonodular synovitis (PVNS) due to a similar frond-like, vascular synovial appearance.\n\nCase Report: We report a 74-year-old male with bilateral grade 4 knee osteoarthritis who underwent total knee arthroplasty. Diffuse villous synovial tissue was encountered intraoperatively, with unexpected bleeding despite tourniquet use. Histopathology confirmed LA. Intra-articular administration of tranexamic acid effectively controlled the bleeding.\n\nConclusion: The clinical outcome is favourable in most cases, unlike with PVNS.\n\nKeywords: Lipoma arborescens, total knee arthroplasty, pigmented villonodular synovitis, frond-like growth, synovial hypertrophy<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i07.7628","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T08:49:02Z","timestamp":1783586942000},"page":"176-179","source":"Crossref","is-referenced-by-count":0,"title":["Lipoma Arborescens of the Knee: An Intraoperative Mimicker of Pigmented Villonodular Synovitis in Bilateral Knee Osteoarthritis \u2013 A Case Report"],"prefix":"10.13107","volume":"16","author":[{"given":"Jagadeesh","family":"Chamundaiah","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Kauvery Hospital, Bengaluru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nirav Rajesh","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Apex Superspeciality Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed Abdul","family":"Mubdi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Kauvery Hospital, Bengaluru, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Senthikumar","family":"Mahalingam","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Royal Cornwall Hospital, Truro, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Edwin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Basildon University Hospital, Basildon, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T08:49:03Z","timestamp":1783586943000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/07\/lipoma-arborescens-of-the-knee-an-intraoperative-mimicker-of-pigmented-villonodular-synovitis-in-bilateral-knee-osteoarthritis-a-case-report\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i07.7628","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
