Twenty-one volunteers (13 females and 8 males) participated, undergoing assessments pre-surgery and nine to 12 months post-surgery. Clinical tests indicated significant reductions in knee pain and improvements in active and passive extension post-surgery. TKA resulted in decreased pain, extension deficits, and functional assessments, with lower scores on the WOMAC questionnaire. A gait analysis showed post-surgery improvements in gait speed (5.8%), cycle time (\u22124.8%), step time (4.4%), double limb support time (\u221211.1%), step (4.4%) and stride (6.3%) lengths, and step (5.1%) and stride (5.0%) cadences. Comparisons between surgical side and limb dominance indicated significant differences in gait speed, stance, swing and step times, double limb support time, step and stride lengths, and step cadence. The non-dominant limb demonstrated greater improvements across most parameters compared to the dominant limb. These findings emphasize the importance of considering the limb dominance of patients with knee osteoarthritis when evaluating post-TKA function. These conclusions can be helpful for personalized rehabilitation programs, allowing tailored interventions for individuals undergoing knee surgery.<\/jats:p>","DOI":"10.3390\/app14198901","type":"journal-article","created":{"date-parts":[[2024,10,2]],"date-time":"2024-10-02T11:29:24Z","timestamp":1727868564000},"page":"8901","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of Spatiotemporal Gait Variables before and after Unilateral Total Knee Arthroplasty"],"prefix":"10.3390","volume":"14","author":[{"given":"David Almeida e","family":"Reis","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, The University Hospital Center of S\u00e3o Jo\u00e3o, 4200-319 Porto, Portugal"},{"name":"Porto Biomechanics Laboratory, University of Porto, 4200-450 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2141-0829","authenticated-orcid":false,"given":"Manoela Vieira","family":"Sousa","sequence":"additional","affiliation":[{"name":"Porto Biomechanics Laboratory, University of Porto, 4200-450 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4885-4924","authenticated-orcid":false,"given":"Pedro","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Porto Biomechanics Laboratory, University of Porto, 4200-450 Porto, Portugal"}]},{"given":"Antoine Amaudric du","family":"Chaffaut","sequence":"additional","affiliation":[{"name":"Porto Biomechanics Laboratory, University of Porto, 4200-450 Porto, Portugal"},{"name":"UFR Sciences et Montagne, Savoie Mont Blanc University, 73370 Bourget du Lac, France"}]},{"given":"Joana","family":"Sousa","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, The University Hospital Center of S\u00e3o Jo\u00e3o, 4200-319 Porto, Portugal"},{"name":"Faculty of Medicine, University of Porto, 4200-319 Porto, Portugal"}]},{"given":"Jennifer","family":"Pires","sequence":"additional","affiliation":[{"name":"Unidade Local de Sa\u00fade de Matosinhos, Department of Physical Medicine and Rehabilitation, 4464-513 Matosinhos, Portugal"}]},{"given":"Fl\u00e1via","family":"Moreira","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, The University Hospital Center of S\u00e3o Jo\u00e3o, 4200-319 Porto, Portugal"}]},{"given":"Filipe","family":"Alves","sequence":"additional","affiliation":[{"name":"Department of Radiology, The University Hospital Center of S\u00e3o Jo\u00e3o, 4200-319 Porto, Portugal"}]},{"given":"Jo\u00e3o","family":"Barroso","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, The University Hospital Center of S\u00e3o Jo\u00e3o, 4200-319 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4109-2939","authenticated-orcid":false,"given":"J.
