Because the articular cartilage tissue in the human body is difficult to heal naturally after injury, once there is a slight crack, it will produce obvious pain. Some people feel that going up and down the stairs hurts their knees, it is difficult to stand up in the toilet, and their legs will suddenly go soft when walking on a flat road. This is because the damaged cartilage is squeezed and rubbed when doing these actions, resulting in pain. Therefore, when there is pain near the patella, try not to do anything to increase the wear of patella cartilage, and try to save the use of the knee joint.
Knee rubbing is widely used in folk, and it is mistaken that friction can make cartilage smooth, reduce friction and relieve pain. In fact, this is completely wrong. This kind of action can only aggravate the damage and wear of cartilage, and make the diseased cartilage worse until the cartilage is worn away and the bone under the cartilage is exposed, and the pain will be more serious. Repeated practice of riding a horse, squatting, standing with legs bent, climbing mountains, climbing stairs or squatting will obviously increase the wear of the patella and aggravate the symptoms.
Then, what activities can you do when your knee is injured to achieve the purpose of fitness and protect your knee as much as possible?
The doctor suggested that if possible, it is best to wear proper knee pads and exercise by swimming. Swimming can not only increase the cardiopulmonary function, but also reduce the joint pressure and joint wear of lower limbs under the buoyancy of water. You can also do brisk walking, because when you walk, your legs are straighter, less bent, more used in other parts of your knee joint, and less worn patella.
