In our joint surgery clinic, the most frequent patients are middle-aged and elderly people who suffer from pain in the knee joints as they age, mostly bilaterally, mainly when going up and down stairs and squatting, and X-rays show joint degeneration, which is often referred to as long bone spurs. For this performance, we consider the most osteoarthritis of the knee joint, which is a manifestation of aging, just like the engine of a car running around on the road is worn out. What can we do about it? It is common to hear patients say, “I have a bone spur, can you help me remove it?” In fact, this is a misunderstanding. The pain in the joints is not caused by bone spurs, which are useful because the joints are degenerating and unstable, and in order to strengthen the stability of the joints, it is a remedy by itself, just like when people get old and their hair turns gray, but we cannot pull out the gray hair, because if we pull out the gray hair, people cannot become younger, and at the same time the trauma will bleed and may become infected, so our bone spurs are not to be removed. Just like gray hair, which is what we call the “gray hair principle”, removing bone spurs will not rejuvenate your joints, but will increase pain, bleeding, and other complications, unless the spurs are blocking the movement of the joint. Our formal treatment plan should be like this, if the symptoms are mild and there is no formal treatment fruit, X shows no significant change in the force line of the joint, you can use conservative treatment: 1, less climbing and stairs, less squatting; 2, more warmth and more heat, the simplest is a hot water bag; 3, strengthen the exercise of thigh muscles, just like a machine will tighten each screw can increase its life; 4. You can take anti-inflammatory and analgesic drugs such as Xilab. If the symptoms are relieved, continue this, if the effect is not good, you can use arthroscopy for clean-up surgery, just like a car going to a service station for a maintenance, but you cannot expect to make your joint a new one through arthroscopy, because the wear and tear of the joint is mainly the wear and tear of the cartilage, and cartilage is disposable for us people. If the effect is still difficult to relieve and the x-ray shows a significant change in the joint force line, you may have to consider artificial joint replacement surgery, just like a person’s tooth pain, when it is still not relieved after taking medication and rinsing, the best thing to do is to get a new denture.
