1. Matters needing attention in daily life 1. If you walk too long and your knees feel comfortable, you should rest immediately. "Rest means walking for a long time." You should also sit or stand for too long. 2. Avoid squatting, squatting and kneeling, such as squatting and hitting Tai Ji Chuan. 3. Keep your weight to reduce the burden on your knees. 4. Pay attention to keep your knees warm. You can wear pants or knee pads to protect your knees. 5. Move less heavy objects, go up and down stairs less, and wear high heels. 6. Avoid trauma and hyperactivity. 2. The healthy exercise of your knee is enough to cause joint stiffness, and excessive exercise will accelerate joint wear. Swimming is very suitable for knee joint exercise, but exercise is based on joint pain. If you feel pain, you should rest. Here are some leg exercises that are helpful to your knee joint: 1. When practicing standing with quadriceps femoris, slowly tighten thigh muscles (keep knees up) and then slowly relax. Whenever you stand, do it at least ten times an hour. After a long time, you can do it spontaneously. Even if you need to think about it. 2. When you lie on your back on the bed or on the ground, slowly lift your legs. The ground is about 1 ft high, keep the knee joint straight to 5, and then slowly lower it. Do it twice a day, 10 or 15 times each time. When you feel that your muscles have improved, you can even add a load near your ankle (carrying books in a handbag can play a very good role). In this sport, athletes can lift a quarter of their weight. 3. Tendon movement behind the leg When you are prone, slowly lift your feet backwards and upwards (bend your knees) and keep this posture slowly until 5. Then put it back slowly. Repeat 10 ~ 15 every day. When your muscles are strengthened, you can put a load on your ankle with the goal of lifting 15% of your body weight. 4. Abductor exercises When you lie on your side (with your legs up), lift your legs (from your hips) about a foot high to make them hang in the air. Do it 10 ~ 15 times each time.
