This study assessed return to work and conversion to TKA rates following PFA in a young, military cohort. Patient demographics, pain scores, and surgical information were retrospectively collected for all active-duty military members who underwent PFA over a 4-year period. The data were then analyzed to calculate return to work, conversion to TKA, and perioperative complications rates. A total of 48 servicemembers with 60 total PFAs (36 unilateral, 12 bilateral) were included, with a mean follow up of 2.2 years. At the final follow-up, 83% of servicemembers returned to military service or completed their service obligation after PFA. Conversion to TKA occurred in three (6.2%) patients at an average of 2.4 years after PFA, resulting in a PFA annual revision rate of 2.3%. The mean numeric rating scale for pain improved from 4.9\u2009\u00b1\u20092.6 at baseline to 2.5\u2009\u00b1\u20092.0 postoperatively (p\u2009&lt;\u20090.001). Servicemembers with at least one prior ipsilateral knee procedure had a significantly decreased odds ratio (OR) for both occupational outcome failure (OR, 0.03; 95% confidence interval [CI], 0\u20130.29) and overall failure (OR, 0.13; 95% CI, 0.02\u20130.78). At an average of 2 years following PFA, 83% of military members returned to duty, with a low rate of revision to TKA. Prior ipsilateral knee procedure decreased the probability of medical separation.<\/jats:p><jats:p>\n          Level of Evidence\u2003IV<\/jats:p>","DOI":"10.1055\/s-0043-1761201","type":"journal-article","created":{"date-parts":[[2023,1,31]],"date-time":"2023-01-31T23:48:32Z","timestamp":1675208912000},"page":"175-182","source":"Crossref","is-referenced-by-count":1,"title":["Occupational and Functional Outcomes following Patellofemoral Arthroplasty in U.S. Military Servicemembers"],"prefix":"10.1055","volume":"37","author":[{"given":"Tuesday F.","family":"Fisher","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery and Rehabilitation, Evans Army Community Hospital, Fort Carson, Colorado"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4430-7066","authenticated-orcid":false,"given":"Danielle E.","family":"Rider","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery, Emory University School of Medicine, Atlanta, Georgia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian R.","family":"Waterman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Wake Forest University School of Medicine, Winston-Salem, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip J.","family":"Belmont","sequence":"additional","affiliation":[{"name":"Department of Surgery, Uniformed Services University of the Health Sciences, Bethesda, Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,1,31]]},"reference":[{"issue":"06","key":"ref1","doi-asserted-by":"crossref","first-page":"757","DOI":"10.1093\/rheumatology\/kei270","article-title":"Prevalence of radiographic osteoarthritis\u2013it all depends on your point of view","volume":"45","author":"R C Duncan","year":"2006","journal-title":"Rheumatology (Oxford)"},{"issue":"05","key":"ref2","doi-asserted-by":"crossref","first-page":"695","DOI":"10.1016\/j.joca.2013.02.003","article-title":"Using magnetic resonance imaging to determine the compartmental prevalence of knee joint structural damage","volume":"21","author":"J J Stefanik","year":"2013","journal-title":"Osteoarthritis Cartilage"},{"issue":"11","key":"ref3","doi-asserted-by":"crossref","first-page":"1704","DOI":"10.1093\/rheumatology\/ken339","article-title":"How do pain and function vary with compartmental distribution and severity of radiographic knee osteoarthritis?","volume":"47","author":"R Duncan","year":"2008","journal-title":"Rheumatology (Oxford)"},{"issue":"03","key":"ref4","doi-asserted-by":"crossref","first-page":"811","DOI":"10.1148\/radiol.2393050253","article-title":"Osteoarthritis of the knee: association between clinical features and MR imaging findings","volume":"239","author":"P R Kornaat","year":"2006","journal-title":"Radiology"},{"issue":"09","key":"ref5","doi-asserted-by":"crossref","first-page":"1151","DOI":"10.1016\/j.joca.2009.03.016","article-title":"Does isolated patellofemoral osteoarthritis matter?","volume":"17","author":"R Duncan","year":"2009","journal-title":"Osteoarthritis Cartilage"},{"issue":"05","key":"ref6","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1111\/j.1600-0838.1999.tb00246.x","article-title":"Sports and risk for severe osteoarthrosis of the knee","volume":"9","author":"H Sandmark","year":"1999","journal-title":"Scand J Med Sci Sports"},{"issue":"02","key":"ref7","doi-asserted-by":"crossref","first-page":"350","DOI":"10.3899\/jrheum.091138","article-title":"Is physical activity a risk factor for primary knee or hip replacement due to osteoarthritis?
