Eligibility
Inclusion criteria
Inclusion criteria: A total of 80 individuals ranging in age from 40 to 89 years were enrolled in this study (comprising 40 patients with early osteoarthritis and 40 patients with late osteoarthritis). All knee OA patients fulfilled the criteria established by the American College of Rheumatology (ACR) and were verified through a comprehensive medical history and examination. They were further classified by two independent orthopedic and radiology physicians using X-ray or MR images, the Kellgren and Lawrence scoring system, and clinical manifestations as either early (undergoing conservative treatment) or late (scheduled for total knee replacement). The physicians were oblivious to the patients' conditions. All eligible and consenting individuals were recruited. Forty age- and sex-matched healthy volunteers who underwent annual routine medical evaluations at a health check-up center and were clinically screened to confirm the absence of any significant joint or spinal OA were enlisted as the healthy control group for this study. All participants had not received radiation therapy, chemotherapy, targeted therapy, or other immunotherapy; their past medical history, current medical history, personal history, postoperative pathology, and environmental data were complete, and they voluntarily signed an informed consent form.
