Objective: The objective of this study was to investigate the relationship between the choice of clinical treatment, gait functionality, and kinetics in patients with comparable knee osteoarthritis.Design: This was an observational case-control study.Setting: The study was conducted in a university biomechanics laboratory.Participants: Knee osteoarthritis patients were stratified into the following groups: clinical treatment (conservative/total knee replacement (TKR) planned), sex (male/female), age (60–67/68–75), and body mass index (BMI) (<30/≥30). All patients had a Kellgren–Lawrence score of 2 or 3 (N = 87).Main Outcome Measures: All patients underwent gait analysis, and two groups of dependent variables were extracted:• Spatiotemporal gait variables: gait velocity, stride time, and double-support time, which are associated with patient functionality.• Kinetic gait variables: vertical, anterior–posterior, and mediolateral ground reaction forces, vertical free moment, joint fo...
