Exclusion criteria
Exclusion criteria: 1.Body Mass Index (BMI) >= 35 kg/m^2 (BMI = weight divided by height squared); 2. Those with severe joint ankylosis or joint fibrosis; 3.

The intended treatment area has undergone arthroscopic debridement and/or received microfracture surgery, mosaicplasty, or autologous cartilage implantation within the past 3 months; 6. According to the Kellgren-Lawrence classification, the osteoarthritis of the affected knee is classified as grade 4; 7. Patients with infectious, autoimmune, or metabolic arthritis; 8. Those who have undergone open joint surgery within the past 6 months; 9. Those who have received steroid medications, Platelet-Rich Plasma (PRP), or intra-articular injections within the past 3 months; 10. Subjects with severe primary cardiovascular disease, pulmonary disease, endocrine and metabolic disease (severe diabetes, severe osteoporosis) or severe diseases affecting their survival, which the investigator deems unsuitable for enrollment; 11. Patients with connective tissue diseases, neurological diseases, or muscle degeneration; 12. Patients who are allergic to the following components and/or have known hypersensitivity reactions, such as those with a history of allergies to collagen, amino acids (especially glutamine, arginine, cysteine, lysine, histidine), and rat proteins; 13.
