Osteoarthritis is actually the aging and degeneration of the knee joint, which will appear after people get old, but may not be found on early X-rays. When the illness breaks out, you should reduce your activities and avoid strenuous or long-term walking. Oral drugs for preventing and treating osteoporosis, diminishing inflammation and relieving pain, if the effect is not obvious, can be sealed and injected into the joint cavity to protect the articular cartilage from damage. It is suggested to go to the orthopedics department of a regular hospital for diagnosis and treatment in time.
