“Bone spurs, as the name suggests, are bony growths. It is due to a part of the human body is subjected to some excessive load, the body in order to adapt to the load and produce a kind of overreaction, so that the local bone abnormal growth. In the knee joint, the formation of this “bone spur” is a long process, it has to undergo a series of degeneration within the joint to be formed. Generally, the pain in our knee joints is due to some damage to the cartilage in our joints, which causes it to fall off or wear out, thus making the contact surfaces of our originally smooth joints become rough and uneven, and the rough surfaces touch each other when we walk and cause pain, which is called osteoarthritis. This is the cause that doctors are most familiar with and explain to their patients most often. In fact, there are many causes of knee pain. Another cause that many doctors tend to overlook is meniscus injury. The meniscus is a unique structure in the knee joint, which has two pieces and is located between the upper and lower bones of the knee joint. Its role is equivalent to the spring shock absorbers on the wheels of our cars, and its function is to spread the load, reduce the shock and impact of walking on the road on the knee joint, so as to play a role in protecting the knee joint. However, because it can only basically move in one plane, it is easy to be damaged when our knee joint moves in multiple directions. The cracks or fragments formed after injury become an obstacle during knee extension and flexion, affecting movement and resulting in pain. Then the knee joint reacts by swelling and becomes unable to straighten or bend, so if you have had knee pain and have recently experienced swelling and immobility, you may feel like your joint is stuck. Often have the feeling that the joint is stuck, must be alert to whether there is meniscus damage, must go to the hospital to do a knee MRI, check the meniscus. It is best to see a specially trained joint doctor for a thorough examination and listen to their advice carefully. Don’t let “bone spurs” delay your condition and waste your money and time.
