In this case report, we describe a case of an elderly patient who presented with a type 2 dislocation after a fall. The mechanisms of inferior patella dislocation, their classification, key imaging features and treatment options are discussed.<\/jats:p>\n                  <jats:p>CASE SUMMARY<\/jats:p>\n                  <jats:p>A 75-year-old woman presented with a right knee fixed flexion deformity after a fall. Preoperative imaging confirmed a vertical intra-articular patella dislocation with a femoral trochlear osteochondral defect and lax though grossly intact patella tendon. Closed reduction was performed under general anaesthesia. Knee arthroscopy confirmed the presence of a femoral trochlear osteochondral defect whose edges were subsequently smoothed and there was debridement of scant debris with thorough irrigation of the joint. Postoperative imaging demonstrated anatomical alignment, however, there was a new nondisplaced medial femoral trochlear. The patient however was able to mobilise well in a range of motion brace set at 0-30 degrees and was discharged 1-day post operatively.<\/jats:p>\n                  <jats:p>CONCLUSION<\/jats:p>\n                  <jats:p>Inferior patella dislocation is rare and this article highlights its types and imaging features which determine the most appropriate management.<\/jats:p>","DOI":"10.5312\/wjo.v16.i12.111602","type":"journal-article","created":{"date-parts":[[2025,12,17]],"date-time":"2025-12-17T01:10:30Z","timestamp":1765933830000},"source":"Crossref","is-referenced-by-count":0,"title":["Inferior patella dislocation in an elderly patient after a fall: A case report"],"prefix":"10.5312","volume":"16","author":[{"given":"Joshua R","family":"Brooks","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex G","family":"Pitman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip","family":"Lucas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald P","family":"Cawthorne","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stuart W T","family":"Wade","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2060","published-online":{"date-parts":[[2025,12,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1177\/23259671221137051"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2014.12.001"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1016\/j.tcr.2021.100481"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2019-232249"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.4021\/jmc968e"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1016\/s0020-1383(02)00046-3"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/691739"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1016\/S0968-0160(03)00042-5"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1097\/BPB.0b013e328357182b"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcot.2016.03.002"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1055\/s-0040-1708516"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.3705"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.CC.17.00112"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199312000-00030"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/535803"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2019.05.041"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1186\/1752-1947-5-347"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1016\/s0020-1383(77)80054-5"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1016\/s0196-0644(84)80532-6"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.1016\/0020-1383(95)00124-r"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-198105000-00016"}],"container-title":["World Journal of Orthopedics"],"original-title":[],"link":[{"URL":"https:\/\/www.wjgnet.com\/2218-5836\/full\/v16\/i12\/111602.htm","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.wjgnet.com\/2218-5836\/full\/v16\/i12\/111602.htm","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,17]],"date-time":"2025-12-17T01:10:53Z","timestamp":1765933853000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.wjgnet.com\/2218-5836\/full\/v16\/i12\/111602.htm"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,18]]},"references-count":21,"journal-issue":{"issue":"12"},"alternative-id":["111602"],"URL":"https:\/\/doi.org\/10.5312\/wjo.v16.i12.111602","relation":{},"ISSN":["2218-5836"],"issn-type":[{"value":"2218-5836","type":"print"}],"subject":[],"published":{"date-parts":[[2025,12,18]]}}}
