We present a case of successful arthroscopic resection of an intra-articular peripheral compartment lipoma in a 69-year-old woman with a coincident labral tear. This woman presented with left hip pain that developed gradually over 2\u2009years and increased over 2\u2009months. MRI showed a fat-intense mass in the anterior aspect of the hip joint, convincing for intra-articular lipoma. Physical examination in the operating room reproduced decreased range of motion and evidence of impingement but with a soft endpoint. Arthroscopy revealed an anterior intrasubstance labral tear, which was debrided. The mass was excised and confirmed as true lipoma on histology. The soft endpoint on examination illustrates that a large lipoma of the hip joint can cause clinical symptoms of impingement in the absence of bony abnormality or trauma.<\/jats:p>","DOI":"10.1136\/bcr-2017-220349","type":"journal-article","created":{"date-parts":[[2017,6,23]],"date-time":"2017-06-23T09:50:33Z","timestamp":1498211433000},"page":"bcr-2017-220349","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Intra-articular lipoma of the hip"],"prefix":"10.1136","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8845-3770","authenticated-orcid":false,"given":"Anthony J","family":"Mells","sequence":"first","affiliation":[{"name":"Oakland University William Beaumont School of Medicine, Rochester, MI, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G Max","family":"Gosey","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University of Arizona Arizona Health Sciences Center, Tucson, AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael P","family":"Muldoon","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of California San Diego School of Medicine, La Jolla, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,6,23]]},"reference":[{"key":"2025082801202902000_2017.jun23_1.bcr-2017-220349.1","doi-asserted-by":"publisher","DOI":"10.1007\/s002640050271"},{"key":"2025082801202902000_2017.jun23_1.bcr-2017-220349.2","unstructured":"Kemp BM , Ahluwalia G , Dowdy Y , et al .
