Why does the elderly still have pain in their knee joints if they continue to exercise?

　　often some elderly Because of knee joint pain Hospital Diagnosis and treatment, and complained to the doctor: I press my legs, shake my knee joints, rub my kneecaps, etc. every day exercise , I often go hiking, but why does my knee joint become more and more painful?

　　All organs of the human body will age to varying degrees as we age. The earliest part of the knee joint to age is the articular cartilage between the patella and the femoral pulley. The function of this joint is to strengthen the force of knee extension, so when the lower limbs are straightened, the patella will press tightly backwards against the femoral pulley well and slide up and down. A lot of friction will occur, and when the wear accumulates to a certain extent. Regardless of whether there is trauma or aging, cartilage will be damaged. Since articular cartilage tissue in the human body is almost unable to heal naturally after damage, significant pain will occur once a slight crack occurs. Some elderly people feel pain in their knee joints when going up and down stairs, find it difficult to stand up when going to the toilet, and their legs suddenly become weak when walking on flat roads. This is because the damaged cartilage is squeezed and rubbed during these movements, causing pain. Therefore, when the elderly have pain near the patella, they should try not to do actions that increase the wear of the patellar cartilage, and try to use the knee joint sparingly.

　　Rubbing the knees is popular among the elderly, with the mistaken belief that the friction can smooth the cartilage and reduce the creaking friction, thereby relieving pain. In fact, this is a completely wrong approach. Such actions can only aggravate the cartilage damage and wear, and wear the diseased cartilage even worse until the cartilage is worn away, exposing the bone underneath the cartilage, and the pain will become more severe. Repeatedly practicing hard kicking movements such as riding a horse and squatting, bending your legs to stand, climbing mountains, climbing stairs, squatting and standing up, etc. will significantly increase the wear of the patella and worsen the symptoms.
