This study compares differences in hospital treatment, morbidity, and mortality associated with periprosthetic distal femur fractures at an urban level 1 trauma center. We retrospectively reviewed all adult AO\/OTA type 33 fractures (526) that presented to our institution between 2009 and 2018. In total, 54 native and 54 periprosthetic fractures were matched by age and gender. We recorded demographics, operative measures, length of stay (LOS), discharge disposition, and mortality. We used McNemar's and paired t-tests for analysis where appropriate (p\u2009&lt;\u20090.05) (IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY; IBM Corp.). The average age at injury was 74 years\u2009\u00b1\u200912 (native) compared with 73 years\u2009\u00b1\u200912 (periprosthetic). After 1:1 matching, the groups had similar body mass index (31.01 vs. 32.98, p\u2009=\u20090.966 for native and periprosthetic, respectively) and mechanisms of injury with 38 native and 44 periprosthetic (p\u2009=\u20090.198) fractures from low-energy falls. Both groups had 51\/54 fractures managed with open reduction internal fixation with a locking plate. The remaining were managed via amputation or intramedullary nail fixation. Mean operative time (144\u2009minutes (\u00b164) vs. 132\u2009minutes (\u00b162), p\u2009=\u20090.96) and estimated blood loss (319\u2009mL (\u00b1362) vs. 289\u2009mL (\u00b1231), p\u2009=\u20090.44) were comparable between the native and periprosthetic groups, respectively. LOS: 9 days\u2009\u00b1\u20097 (native) versus 7 days\u2009\u00b1\u20095 (periprosthetic, p\u2009=\u20090.31); discharge disposition (to skilled nursing facility\/rehab): n\u2009=\u200947 (native) versus n\u2009=\u200943 (periprosthetic, p\u2009=\u20090.61); and mortality: n\u2009=\u20096 (native) versus n\u2009=\u20098 (periprosthetic, p\u2009=\u20090.55). No significant differences were observed. We found no statistical differences in morbidity and mortality in periprosthetic distal femur fractures treated over 10 years at a level 1 trauma center. Native and periprosthetic AO\/OTA type 33 distal femur fractures are serious injuries with similar outcomes at a level 1 trauma center.<\/jats:p>","DOI":"10.1055\/s-0042-1749604","type":"journal-article","created":{"date-parts":[[2022,7,12]],"date-time":"2022-07-12T22:56:15Z","timestamp":1657666575000},"page":"1111-1115","source":"Crossref","is-referenced-by-count":11,"title":["Comparable Outcomes Between Native and Periprosthetic Fractures of the Distal Femur"],"prefix":"10.1055","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7707-0790","authenticated-orcid":false,"given":"Matthew W.","family":"Kaufman","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander S.","family":"Rascoe","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey L.","family":"Hii","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitchell L.","family":"Thom","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ari D.","family":"Levine","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"},{"name":"Department of Orthopedic Surgery, MetroHealth Medical Center, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roger G.","family":"Wilber","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"},{"name":"Department of Orthopedic Surgery, MetroHealth Medical Center, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam G.","family":"Hirschfeld","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"},{"name":"Department of Orthopedic Surgery, MetroHealth Medical Center, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas M.","family":"Romeo","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"},{"name":"Department of Orthopedic Surgery, MetroHealth Medical Center, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Glenn D.","family":"Wera","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Case Western Reserve University School of Medicine Cleveland, Ohio"},{"name":"Department of Orthopedic Surgery, MetroHealth Medical Center, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2022,7,12]]},"reference":[{"issue":"S 02","key":"ref1","doi-asserted-by":"crossref","first-page":"S66","DOI":"10.1097\/BOT.0b013e31821b8c28","article-title":"Periprosthetic fractures: epidemiology and future projections","volume":"25","author":"G J Della Rocca","year":"2011","journal-title":"J Orthop Trauma"},{"issue":"01","key":"ref2","doi-asserted-by":"crossref","first-page":"27","DOI":"10.2106\/00004623-199301000-00005","article-title":"Operative treatment of distal femoral fractures proximal to total knee replacements","volume":"75","author":"W L Healy","year":"1993","journal-title":"J Bone Joint Surg Am"},{"issue":"03","key":"ref3","doi-asserted-by":"crossref","first-page":"130","DOI":"10.1097\/BOT.0000000000000282","article-title":"Periprosthetic femur fractures","volume":"29","author":"W M Ricci","year":"2015","journal-title":"J Orthop Trauma"},{"issue":"12","key":"ref4","doi-asserted-by":"crossref","first-page":"1576","DOI":"10.1302\/0301-620X.90B12.20681","article-title":"European validation of the Vancouver classification of periprosthetic proximal femoral fractures","volume":"90","author":"F Rayan","year":"2008","journal-title":"J Bone Joint Surg Br"},{"issue":"06","key":"ref5","doi-asserted-by":"crossref","first-page":"1215","DOI":"10.2106\/00004623-200606000-00007","article-title":"Three hundred and twenty-one periprosthetic femoral fractures","volume":"88","author":"H Lindahl","year":"2006","journal-title":"J Bone Joint Surg Am"},{"issue":"07","key":"ref6","doi-asserted-by":"crossref","first-page":"E791","DOI":"10.3390\/ma10070791","article-title":"Ultra-high molecular weight polyethylene: influence of the chemical, physical and mechanical properties on the wear behavior.
