There are several factors that increase the risk of this injury, including patient comorbidities, anatomic considerations, and surgical technique. With these factors limiting healing ability in the area, periprosthetic patellar fractures can pose a major challenge to treat, with potentially lasting morbidity for affected patients. These fractures can occur at any time following TKA and are classified based on their associated implant stability and disruption of the extensor mechanism using the Ortiguera and Berry classification system. Each of the three types of fractures can be managed in their own unique way; however, outcomes remain poor, and the complication rates remain high regardless of fracture type. This article provides an overview of the current literature and the recommended management of periprosthetic patella fractures.<\/jats:p>","DOI":"10.1055\/a-2376-6721","type":"journal-article","created":{"date-parts":[[2024,7,31]],"date-time":"2024-07-31T19:22:00Z","timestamp":1722453720000},"page":"652-655","source":"Crossref","is-referenced-by-count":0,"title":["Patella Fractures after Total Knee Arthroplasty"],"prefix":"10.1055","volume":"38","author":[{"given":"Gabrielle","family":"Swartz","sequence":"additional","affiliation":[{"name":"LifeBridge Health, The Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"Albana","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Lenox Hill Hospital, Northwell Orthopaedic Institute, New York, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeremy A.","family":"Dubin","sequence":"additional","affiliation":[{"name":"LifeBridge Health, The Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Hameed","sequence":"additional","affiliation":[{"name":"LifeBridge Health, The Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandeep S.","family":"Bains","sequence":"additional","affiliation":[{"name":"LifeBridge Health, The Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael A.","family":"Mont","sequence":"additional","affiliation":[{"name":"LifeBridge Health, The Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5651-2625","authenticated-orcid":false,"given":"Ronald E.","family":"Delanois","sequence":"additional","affiliation":[{"name":"LifeBridge Health, The Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giles R.","family":"Scuderi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Lenox Hill Hospital, Northwell Orthopaedic Institute, New York, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2024,8,30]]},"reference":[{"issue":"02","key":"ref1","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1016\/S0030-5898(05)70073-0","article-title":"Epidemiology: hip and knee","volume":"30","author":"D J Berry","year":"1999","journal-title":"Orthop Clin North Am"},{"issue":"09","key":"ref2","doi-asserted-by":"crossref","first-page":"663","DOI":"10.1097\/BOT.0b013e31816ed989","article-title":"Periprosthetic knee fractures","volume":"22","author":"J Parvizi","year":"2008","journal-title":"J Orthop Trauma"},{"issue":"236","key":"ref3","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1097\/00003086-198811000-00013","article-title":"Patellar fracture type and prognosis in condylar total knee arthroplasty","author":"V M Goldberg","year":"1988","journal-title":"Clin Orthop Relat Res"},{"issue":"230","key":"ref4","doi-asserted-by":"crossref","first-page":"168","DOI":"10.1097\/00003086-198805000-00018","article-title":"Fracture of the patella after total knee arthroplasty","author":"J N Grace","year":"1988","journal-title":"Clin Orthop Relat Res"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"S63","DOI":"10.1016\/S0883-5403(89)80009-9","article-title":"Patellar fractures in total knee arthroplasty","volume":"4","author":"R E Windsor","year":"1989","journal-title":"J Arthroplasty"},{"issue":"170","key":"ref6","doi-asserted-by":"crossref","first-page":"152","DOI":"10.1097\/00003086-198210000-00020","article-title":"Patellar complications after total condylar arthroplasty","author":"M L Clayton","year":"1982","journal-title":"Clin Orthop Relat Res"},{"issue":"416","key":"ref7","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1097\/01.blo.0000092992.90435.20","article-title":"Patella fracture after post total knee replacements","author":"E M Keating","year":"2003","journal-title":"Clin Orthop Relat Res"},{"volume-title":"2023 Annual Report","year":"2023","author":"American Joint Replacement Registry (AJRR)","key":"ref8"},{"issue":"06","key":"ref9","doi-asserted-by":"crossref","first-page":"714","DOI":"10.1016\/j.injury.2007.02.054","article-title":"Management of periprosthetic patellar fractures.
