[0001] The invention relates to the field of medical instruments, and in particular to a patella scraping device based on tendon and bone theory of traditional Chinese medicine. Background Art

[0002] Knee osteoarthritis (KOA) is a common chronic disease in orthopedics and one of the common chronic diseases that seriously affects people's quality of life. It is common in middle-aged and elderly people and is a degenerative joint disease. Clinically, it mainly manifests as joint swelling, pain, deformity, etc. The main purpose of treatment is to reduce or eliminate pain, correct joint deformity, improve or restore joint function, and improve the patient's quality of life.

[0003] Primary knee osteoarthritis is common clinically, with knee pain accompanied by limited mobility, intolerance to long-term walking, aversion to cold and preference for warmth, and difficulty walking after sitting for a long time as the main symptoms. The treatment principle for KOA is to select corresponding treatment measures based on the main symptoms and their severity, but the current clinical treatment effect is still not ideal. Traditional Chinese medicine treats KOA from a holistic perspective and has a systematic and unique understanding of the etiology, pathogenesis, and diagnosis and treatment of this disease. KOA is one of the diseases that TCM has advantages in treating, and belongs to the category of "arthralgia" in TCM. In particular, the scraping technique for the patella is quite unique to TCM and has a definite effect.
