I am in my 70’s and have severe pain in my knee when I walk. I can take painkillers to relieve the pain for a while, but after I stop taking them, I am back to my old self. Is there any popping or tenderness in the joint? It is likely that you have osteoarthritis of the knee, and you need to check the front and side views of both knees. If the disease is diagnosed, it is advisable to: 1. reduce activities such as going up and down stairs and squatting and standing, apply a cane and other supports, protect the knee, avoid getting cold, and do functional exercises for the quadriceps. 2. Drug therapy: A. Anti-osteoporosis treatment; B. Oral non-steroidal anti-inflammatory drugs such as Cilobal, Aceclofenac, etc. when pain is obvious (pay attention to gastrointestinal reactions); C. Oral aminoglucose preparation; D. Intra-articular injection of sodium hyaluronate or glycocorticoid; E. Topical ointment. 3.Physical therapy: ultrashort wave, magnetic therapy, shock wave, etc. 4. Small needle treatment to loosen the peripatellar soft tissue. 5.Surgical treatment: A. Arthroscopic surgical treatment; B. Artificial joint replacement. Article 1 is a mandatory item, and articles 2-5 are selected depending on the severity of the disease. Patient: I’m sorry to bother you so late, thank you for your detailed answer, Dr. Tong.
