The bone spur itself is not painful, but it is the long-term stimulation of the tissues around the spur that causes pain and other symptoms, which is why it is medically known as “osteoarthritis of the knee”. Now that we understand why this disease occurs, all we have to do is to prevent and treat it. Understanding that bone spurs cause knee pain due to cumulative wear and tear of the knee joint, patients should get out of the misconception that they should exercise more to wear the spurs away. First of all, you should avoid frequent squatting and prolonged walking, as well as excessive climbing and repeated up and down stairs, which aggravate the wear and tear on the knee joint, and keep warm to avoid aggravating the condition by cold stimulation. For obese patients, it is important to reduce the weight of the knee joint by moderating the diet. With reasonable prevention, the development of knee pain will be greatly reduced. What should be done for patients with bone spurs who have already experienced knee pain? In early stage “bone spur”, Chinese herbal fumigation, hot compress, ointment, local physiotherapy, intra-articular drug injections, oral administration of homemade medicine “bone strengthening capsule” and joint cartilage protector can be used to reduce the symptoms of knee joint swelling and pain. In the middle stage of “bone spur” treatment, we can use minimally invasive “knee arthroscopy” to clean the joint cavity based on the earlier treatment methods. This procedure removes debris and inflammatory substances from the joint that have been worn for a long time, thus effectively reducing swelling and pain in the knee joint. This “knee arthroscopy” procedure can be performed with only two small incisions of about 0.5 cm, and the risks and side effects of the procedure are minimal. In advanced cases of “bone spurs”, where the knee joint is extensively enlarged and deformed, “surface knee replacement surgery” is required. As the name implies, this procedure involves the installation of two artificial covers on the extensively enlarged knee joint, similar to the installation of “braces” on a damaged tooth. This procedure can significantly improve the quality of life and survival of the patient. In conclusion, the “bone spur” of the knee joint is not a terrible problem and can be treated with good results with regular prevention and treatment.
