A diagnosis of KOA can be made if criterion 1) is met along with any two of the other criteria. Diagnostic criteria for early and middle stages: Refer to the diagnostic criteria for early and middle stages of KOA established in the 2024 edition of the 'Chinese Guidelines for the Diagnosis and Treatment of Osteoarthritis' and the 'Expert Consensus on the Integrated Traditional Chinese and Western Medicine Treatment of Knee Osteoarthritis (Xibì)'. Inclusion criteria for KOA patients: 1) Aged 50–70 years, regardless of gender; 2) Consent to undergo gait analysis, blood sampling and other examinations, and ability to perform the exercise movements independently (without the need for assistive devices); 3) BMI < 28 kg/m²; 4) Voluntary participation and signing of an informed consent form; 5) Meeting the diagnostic criteria for early- to mid-stage KOA as outlined above. Inclusion criteria for healthy subjects: 1) Aged 50–70 years, regardless of gender; 2) Consent to undergo examinations such as gait analysis and blood sampling; 3) BMI < 28 kg/m²; 4) Voluntary participation and signing of an informed consent form.
