Double knee arthritis treatment methods include drug treatment and surgical treatment. 1. Drug treatment: commonly used drugs include local treatment drugs, systemic anti-inflammatory and analgesic drugs, and joint cavity injection drugs. (1) Local treatment drugs: for example, Mesoprofen paste, etc., can relieve the pain of joints, and the adverse reaction is small. (2) Systemic anti-inflammatory and analgesic drugs, such as celecoxib, can delay the course of the disease and improve symptoms. (3) Joint cavity injection drugs: such as glucocorticoids, etc., can relieve patients’ pain. 2. Surgical treatment: commonly used surgical methods include artificial knee joint replacement, knee cartilage repair, joint fusion and osteotomy. (1) Artificial joint replacement: it is the main treatment for advanced knee osteoarthritis, aiming at restoring joint function and solving pain completely. (2) Articular cartilage repair: the purpose is to repair the damaged cartilage. (3) Joint fusion: it is suitable for patients whose non-surgical treatment is ineffective and unsuitable for joint replacement, with the aim of resolving the patient’s pain. (4) Osteotomy: suitable for patients with high activity, young and middle-aged patients, and patients with unilateral lesions, to restore the function of the knee joint as much as possible and maximize the preservation of the joint. If the diagnosis of double knee arthritis is confirmed, it is recommended to go to the hospital for consultation, and make appropriate treatment plan under the guidance of the doctor.
