Preoperative CT scans with stifles in three positions: extended (155\u2013165\u00b0), neutral (85\u201395\u00b0) and flexed (35\u201345\u00b0). Lateral stifle arthrotomy was followed by BRT. CT scans were taken as above. PPP was performed so the width of the patella was 1\u2009mm narrower than the BRT. CT scans were repeated and CT measurements were taken.<\/jats:p><jats:p>\n          Results\u2003The area of contact between the patella and femoral trochlea was significantly reduced after BRT and then significantly increased after PPP. The depth of patellar recession was unchanged after BRT, but then was significantly higher after PPP. The patella was wider than the trochlea preoperatively and post-BRT and narrower post-PPP. Reduction in bone volume following PPP (mean: 20%) was 50% the reduction in patella width (mean: 40%).<\/jats:p><jats:p>\n          Conclusion\u2003Block recession trochleoplasty did not improve patellar recession and decreased patellofemoral contact area. Following BRT, the patella rides the trochlear ridges and loses contact with the trochlear sulcus. Block recession trochleoplasty alone should not be performed in cats. Instead, BRT should be combined with PPP.<\/jats:p>","DOI":"10.1055\/s-0039-3400313","type":"journal-article","created":{"date-parts":[[2020,1,24]],"date-time":"2020-01-24T23:44:24Z","timestamp":1579909464000},"page":"102-109","source":"Crossref","is-referenced-by-count":11,"title":["Computed Tomographic Assessment of Block Recession Trochleoplasty and Partial Parasagittal Patellectomy in Cats"],"prefix":"10.1055","volume":"33","author":[{"given":"Valentina","family":"Brioschi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Cambridge, Cambridge, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynda","family":"Rutherford","sequence":"additional","affiliation":[{"name":"The Department of Clinical Science and Services, The Royal Veterinary College, London University, Hatfield, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karin","family":"Newell","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Cambridge, Cambridge, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Trotter","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Cambridge, Cambridge, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gareth I.","family":"Arthurs","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Cambridge, Cambridge, United Kingdom"},{"name":"Arthurs Orthopaedics, Hardwick, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2020,1,24]]},"container-title":["Veterinary and Comparative Orthopaedics and Traumatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0039-3400313.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,21]],"date-time":"2020-03-21T23:32:04Z","timestamp":1584833524000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0039-3400313"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,1,24]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2020,3,21]]},"published-print":{"date-parts":[[2020,3]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0039-3400313","relation":{},"ISSN":["0932-0814","2567-6911"],"issn-type":[{"value":"0932-0814","type":"print"},{"value":"2567-6911","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,1,24]]}}}
