These reports relate to separation of superolateral bipartite patella (Saupe type 3). We describe a new variant which to our knowledge has not been described or classified so far, which is purely a superior bipartite patella with traumatic separation and complete functional disruption of the extensor mechanism of the knee in a young patient working in the army which was managed with open reduction and internal fixation along with repair of the extensor mechanism of the knee achieving complete functional recovery.<\/jats:p>","DOI":"10.1136\/bcr-2020-236773","type":"journal-article","created":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T11:40:50Z","timestamp":1610710850000},"page":"e236773","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["New variant of bipartite patella with traumatic separation and complete disruption of the extensor mechanism of the knee"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8673-5950","authenticated-orcid":false,"given":"Kiran Kumar","family":"Naikoti","sequence":"first","affiliation":[{"name":"Trauma and Orthopaedics, Countess of Chester Hospital NHS Foundation Trust, Chester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raghuram","family":"Thonse","sequence":"additional","affiliation":[{"name":"Trauma and Orthopaedics, Countess of Chester Hospital NHS Foundation Trust, Chester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,1,15]]},"reference":[{"key":"2025082702534113000_14.1.e236773.1","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1053\/jars.2003.50055","article-title":"Bipartite patella fracture","volume":"19","author":"Canizares","year":"2003","journal-title":"Arthroscopy"},{"key":"2025082702534113000_14.1.e236773.2","doi-asserted-by":"crossref","first-page":"1108","DOI":"10.4067\/S0717-95022015000300047","article-title":"Prevalence of bipartite patella in Turkish population: analysis of bilateral knee radiographs in 897 subjects","volume":"33","author":"Kose","year":"2015","journal-title":"Int J Morphol"},{"key":"2025082702534113000_14.1.e236773.3","doi-asserted-by":"crossref","first-page":"83","DOI":"10.1007\/s00167-006-0107-9","article-title":"Traumatic separation of an uncommon bipartite patella type: a case report","volume":"15","author":"Tauber","year":"2007","journal-title":"Knee Surg Sports Traumatol Arthrosc"},{"key":"2025082702534113000_14.1.e236773.4","doi-asserted-by":"crossref","first-page":"386","DOI":"10.1007\/BF02793437","article-title":"Prim\u00c4re Knochenmarkseiterung Der Kniescheibe","volume":"258","author":"Saupe","year":"1943","journal-title":"Deutsche Zeitschrift f.
