This study aimed to investigate the knee kinetics, kinematics, pain, and physical function in individuals with moderate symptomatic KOA, in comparison to asymptomatic control participants. Thirty volunteers with moderate KOA (with flat feet n\u2009=\u200915, with normal feet n\u2009=\u200915) and 30 asymptomatic people (with flat feet n\u2009=\u200915, with normal feet n\u2009=\u200915) were evaluated. The knee adduction angular impulse, knee flexion moment, knee flexion angular impulse, and knee flexion angle were measured during level walking. The pain was assessed in patients with KOA. The study found that individuals with KOA had a significant increase in the knee adduction angular impulse compared with the asymptomatic people (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.05). The KOA with flat feet group had significantly lower knee flexion moment, knee flexion angular impulse, and knee flexion angle values than the KOA with normal feet group (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.05). Furthermore, the KOA with flat feet group had a higher pain score than the KOA with normal feet group. Individuals with osteoarthritis and flat feet had lower knee flexion moments which may indicate reduced knee force exerted through compensatory mechanisms. Despite this reduction, they reported significantly higher levels of pain compared with those without flat feet, a finding that warrants further investigation in future studies.<\/jats:p>","DOI":"10.1123\/jab.2023-0143","type":"journal-article","created":{"date-parts":[[2024,4,12]],"date-time":"2024-04-12T18:28:18Z","timestamp":1712946498000},"page":"232-240","source":"Crossref","is-referenced-by-count":4,"title":["Comparing Knee Kinetics and Kinematics in Healthy Individuals and Those With Knee Osteoarthritis, With and Without Flat Feet"],"prefix":"10.1123","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3736-2731","authenticated-orcid":true,"given":"Maryam","family":"Sohrabi","sequence":"first","affiliation":[{"name":"Physical Therapy Department, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7625-8759","authenticated-orcid":true,"given":"Giti","family":"Torkaman","sequence":"additional","affiliation":[{"name":"Physical Therapy Department, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8214-1821","authenticated-orcid":true,"given":"Fariba","family":"Bahrami","sequence":"additional","affiliation":[{"name":"Human Motor Control and Computational Neuroscience Lab, School of Electrical and Computer Engineering, College of Engineering, University of Tehran, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"2","key":"r1","series-title":"Arch.
