The primary objective of this prospective study was to investigate whether there is a correlation between dynamic plantar pressures and spatiotemporal parameters of gait and the coronal alignment of the lower limb after unilateral TKR for primary knee osteoarthritis (KOA). Methods: Thirty-two consecutive patients scheduled for TKR were evaluated preoperatively and at six months postoperatively. Changes in plantar pressure distribution and spatiotemporal gait parameters were collected using a multiplatform plantar pressure analysis system (PPAS), while coronal alignment was assessed using the femorotibial angle (FTA). Relationships with preoperative, postoperative, and correction-related alignment measures were examined using non-parametric statistical methods. Results: Dynamic plantar pressures and spatiotemporal gait parameters were not found to be consistently associated with pre- or postoperative values of FTA, respectively. Furthermore, the degree of correction did not appear to influence baropodometric outcomes. Conclusions: Static coronal alignment, as defined by the FTA, was not found to be consistently associated with dynamic plantar pressure patterns or spatiotemporal gait parameters at six months following unilateral TKR in our study population. These findings highlight the potential limitations of using solely static radiographic markers to evaluate complex functional outcomes such as gait.<\/jats:p>","DOI":"10.3390\/bioengineering13020134","type":"journal-article","created":{"date-parts":[[2026,1,23]],"date-time":"2026-01-23T17:52:38Z","timestamp":1769190758000},"page":"134","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond Alignment: Static Coronal Alterations Do Not Predict Dynamic Foot Loading or Spatiotemporal Gait Patterns After Unilateral Total Knee Replacement\u2014A Prospective Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0736-8794","authenticated-orcid":false,"given":"Dimitrios","family":"Ntourantonis","sequence":"first","affiliation":[{"name":"Emergency Department, University Hospital of Patras, 26504 Patras, Greece"},{"name":"Department of Medicine, School of Health Sciences, University of Patras, 26504 Patras, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4814-1449","authenticated-orcid":false,"given":"Ilias","family":"Iliopoulos","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic, Famagusta (Ammochostos) General Hospital, 5284 Paealimni, Cyprus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3917-5189","authenticated-orcid":false,"given":"Konstantinos","family":"Pantazis","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic, Central Hospital of Karlstad, 65185 Karlstad, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3265-5522","authenticated-orcid":false,"given":"Angelos","family":"Kaspiris","sequence":"additional","affiliation":[{"name":"Third Department of Orthopaedic and Medical School, National Kapodistrian University of Athens, 14561 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4545-8675","authenticated-orcid":false,"given":"Zinon","family":"Kokkalis","sequence":"additional","affiliation":[{"name":"Department of Medicine, School of Health Sciences, University of Patras, 26504 Patras, Greece"},{"name":"Department of Orthopaedic, University Hospital of Patras, 26504 Patras, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Gliatis","sequence":"additional","affiliation":[{"name":"Department of Medicine, School of Health Sciences, University of Patras, 26504 Patras, Greece"},{"name":"Department of Orthopaedic, University Hospital of Patras, 26504 Patras, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elias","family":"Panagiotopoulos","sequence":"additional","affiliation":[{"name":"Department of Medicine, School of Health Sciences, University of Patras, 26504 Patras, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"893","DOI":"10.1302\/0301-620X.89B7.19091","article-title":"The role of pain and function in determining patient satisfaction after total knee replacement.
