Patient: Description of condition (onset time, main symptoms, hospital visited, etc.): Patient female, 77 years old, this condition: about a month, left leg knee pain, to the hospital to check the x-ray, the results are suffering from bone spurs. Ten days ago, she had physiotherapy and massage treatment in the hospital, but the effect was not obvious, and the pain suddenly increased in the past few days. Can you give me any advice on treatment? Can I see you? Jian Shen, Department of Orthopedics, Beijing Hospital, Ministry of Health: This is a common osteoarthritis in the elderly, which is due to bone and joint degeneration, mainly degeneration and wear of joint cartilage, leading to joint instability, which in turn leads to joint hyperplasia and deformation. If the hyperplasia is serious and the symptoms are severe (walking on a flat road is painful), I am afraid that only artificial knee replacement can be considered. If the pain is early to moderate or if it is a first-time offender, you may consider: 1. injecting sodium glacial in the joint cavity once a week for 5 times, 2. taking oral glucosamine drugs for 3 months, 3. adding anti-inflammatory painkillers recently (short-term), 4. local physical therapy for the affected area, 5. avoiding stair climbing, mountain climbing, heavy lifting, and squatting exercises, 6. keeping the area warm, 7. lying on the back for straight leg Elevation exercises.
