Measurements that describe the bone block harvest site geometry were used to calculate three normalized parameters. The relative depth parameter describes the thickness of the bone block harvest site with respect to the thickness of the patella at the harvest site. The asymmetry parameter defines the medial\u2013lateral location of the bone bock harvest site. The normalized bending stress parameter assesses the bending stress experienced by the remaining bone beneath the bone block harvest site.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The relative depth of the bone block harvest site in the non\u2010fractured patellae was 27 \u00b1 12 % and for the fractured patellae was 42 \u00b1 14 % (<jats:italic>p<\/jats:italic> &lt; 0.05). With a value &lt;1\u00a0indicating a more lateral location of the harvest site, asymmetry for the non\u2010fractured group was 1.0 \u00b1 0.5 and 0.7 \u00b1 0.4 for the fractured group (n.s.).

In order to minimize the incidence of a patellar fracture, bone blocks should not be taken laterally and should not exceed 30 % of the total patella thickness at the harvest site.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-015-3550-7","type":"journal-article","created":{"date-parts":[[2015,3,6]],"date-time":"2015-03-06T09:37:35Z","timestamp":1425634655000},"page":"2899-2905","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Quantitative analysis of the patella following the harvest of a quadriceps tendon autograft with a bone block"],"prefix":"10.1002","volume":"24","author":[{"given":"Gerald A.","family":"Ferrer","sequence":"first","affiliation":[{"name":"Orthopaedic Robotics Laboratory Pittsburgh PA USA"},{"name":"Department of Bioengineering Swanson School of Engineering University of Pittsburgh 300 Technology Drive, 306 CNBIO 15219 Pittsburgh PA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
