Given the reciprocal changes in lower extremity alignment associated with planovalgus foot deformity, it has been suggested that patients with this deformity has worse outcomes following total knee arthroplasty (TKA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective cohort analysis of patients undergoing elective TKA was conducted using the PearlDiver database. Patients were stratified into three cohorts: those without pes planovalgus, patients with ipsilateral or bilateral pes planovalgus relative to the TKA, and patients with contralateral pes planovalgus. Patients with prior foot reconstructive surgery were excluded. The cohorts were each matched to those without pes planovalgus. Bivariate analysis was performed comparing 90\u2010day medical complications and 2\u2010 and 4\u2010year revisions following TKA. An adjusted number needed to be exposed for one additional person to be harmed (NNEH) was calculated using the adjusted odds ratio (OR) and unexposed event rate.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Following matched analysis, those with contralateral pes planovalgus had similar odds (OR 3.41; 95% CI 0.93\u201312.54; <jats:italic>p<\/jats:italic>\u2009=\u2009n.s.) for aseptic revision within 2 years but significantly higher odds (OR 3.35; 95% CI 1.08\u201310.41; <jats:italic>p<\/jats:italic>\u2009=\u20090.03) within 4 years when compared to those without a pes planovalgus deformity. Within 4 years, there was no significant difference in the incidence of aseptic revision (<jats:italic>p<\/jats:italic>\u2009=\u2009n.s.) in patients with ipsilateral\/bilateral pes planovalgus. No patients in any cohort underwent septic revision within 4 years of TKA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study found that patients with contralateral pes planovalgus deformity had higher odds of aseptic revision within 4 years following primary TKA in a national database, suggesting that the change in gait kinematics associated with this deformity could possibly be associated with increased revision rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Level III.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-023-07520-x","type":"journal-article","created":{"date-parts":[[2023,8,18]],"date-time":"2023-08-18T12:56:24Z","timestamp":1692363384000},"page":"4920-4926","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Higher revision rates in patients with preoperative contralateral pes planovalgus deformity following total knee arthroplasty"],"prefix":"10.1002","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2917-1682","authenticated-orcid":false,"given":"Zachary C.","family":"Pearson","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery The Johns Hopkins University School of Medicine 601 North Caroline Street 21287 Baltimore MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew B.","family":"Harris","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery The Johns Hopkins University School of Medicine 601 North Caroline Street 21287 Baltimore MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amil R.","family":"Agarwal","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery The Johns Hopkins University School of Medicine 601 North Caroline Street 21287 Baltimore MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
