BACKGROUND:Traditional assessment methods for knee osteoarthritis rely on clinical symptoms,physical examinations,and imaging findings of patients.However,these methods fail to reflect the dynamic changes in knee joint kinetics and do not comprehensively depict the objective status of the knee joint.The emergence of the 6 degree of freedom gait analysis system provides a more objective and practical dynamic assessment method for the severity of knee osteoarthritis.This system serves as a basis for more precise treatment strategies for different patients,thereby optimizing patient treatment approaches.OBJECTIVE:To review relevant assessment systems for knee osteoarthritis,compare the 6 degree of freedom gait analysis with traditional methods for assessing knee osteoarthritis severity,and explore the application of 6 degree of freedom gait analysis in guiding knee osteoarthritis treatment strategies.METHODS:A computer search was conducted using Google Scholar and PubMed databases for relevant articles published from January 2002 to June 2023.English search terms included"knee osteoarthritis,knee osteoarthritis severity,6DOF gait analysis,evaluation methods,WOMAC,KOOS."Chinese search terms were"knee osteoarthritis,osteoarthritis evaluation system,6 degree of freedom gait analysis."Based on inclusion and exclusion criteria,a total of 65 articles were selected for synthesis and summarization.RESULTS AND CONCLUSION:(1)The 6 degree of freedom gait analysis improves the accuracy of knee osteoarthritis severity assessment.Treatment plans based on this method significantly improved patient prognosis.(2)Current research findings suggest standardizing the integration of 6 degree of freedom gait analysis and traditional assessment methods in clinical practice for an objective and accurate evaluation of knee osteoarthritis.This enables better selection of treatment plansand evaluation of the long-term effectiveness of individualized treatment strategies.
