The treatment of osteoarthritis of the knee joint 1, non-surgical treatment (conservative therapy) (1) physical therapy Commonly used physical therapy methods include Chinese acupuncture, fumigation, medical magnetic therapy knee care magnetic therapy. Heat therapy, hydrotherapy, infrared, ultra-short wave, electrical stimulation, etc. can enhance local blood circulation, relieve muscle tension, and reduce pain and other symptoms. (2) Acupuncture treatment Acupuncture is effective in the treatment of knee osteoarthritis. According to research, acupuncture has the effects of anti-inflammation, pain relief, swelling and blood circulation, etc. By changing the blood flow and blood flow rate of the affected area, some of the inflammatory factors causing the disease are taken away to improve the symptoms. (3) Medication Currently, medication for arthritis includes oral medication, topical medication and joint injections. Oral and topical medications: anti-inflammatory and analgesic medications, glucosamine and other drugs for nutrition and cartilage protection, and vitamins A, C and E antioxidants can be taken orally. Joint cavity injection: glucocorticoids, sodium hyaluronate viscoelastic supplements, or Chinese herbal medicines, such as Angelica injection, Salvia injection, compound safflower injection, etc., can be used for intra-articular injection. (1) Arthroscopic techniques Arthroscopic exploration and cleaning of the knee is a safe and practical new technique for the diagnosis and treatment of knee diseases, which is characterized by less pain, fewer complications, quicker recovery and more effective treatment. The development of arthroscopic techniques has increased the chances of early surgical treatment of this disease. (2) Borehole decompression Elevated intraosseous pressure and intraosseous stasis are important in the pathogenesis of knee OA, and are also important causes of joint pain and functional impairment. The use of borehole decompression can reduce intraosseous pressure and improve intraosseous stasis, and can reconstruct the blood return pathway to relieve pain, improve joint movement, and interrupt the development of lesions. (3) High tibial osteotomy can correct the abnormal negative gravity line, transfer the load of the knee joint from the damaged joint space to a more normal joint space, thus changing the joint load, reducing intraosseous pressure, promoting the formation of new joint surfaces, and reducing pain. The operation is simple and short, and the patient can walk early. (4) Knee joint replacement Artificial knee joint replacement is a surgical procedure in which the damaged knee joint is partially or completely replaced by an artificial joint component, in which the worn and damaged joint surface is removed and implanted like a brace to restore a normal smooth joint surface. (5) Minimally invasive technology Under the precise guidance of cT, a hair-thin puncture needle is used to inject safe and side-effect-free medical triple oxygen into the lesion, which can completely remove the inflammatory factors from the lesion and have an anti-inflammatory and relaxing effect on the lesion; it can also increase the blood oxygen saturation, increase the oxygen content of cells, activate the metabolism and promote the growth and recovery of the body; and then help the bone repair and growth to achieve the purpose of treatment.
