My knee can't be straightened and it hurts so much, what should I do?

The knees can never be straightened, and once they are straightened, it is extremely painful. Of course, nursing work cannot be ignored. First of all, you need to pay attention to avoiding being too fat, because being too fat will bring a greater burden to your habits, so you need to focus on losing weight. At the same time, you also need to develop good living habits and avoid sitting or standing for long periods of time.

1. Try to avoid obesity to prevent increasing the burden on the knee joints. Once you are overweight, you should actively lose weight and control your weight.

2. Pay attention to your walking and working posture, and do not twist your body while walking or working. Avoid squatting for long periods of time, because the load on the knee joint when squatting is 3 to 6 times of one's own body weight. When squatting at work (such as auto mechanics, foundry workers), it is best to change to a low sitting position (sitting on a small bench). When sitting or standing for a long time, you should also change your posture frequently to prevent the knee joint from being fixed in one posture and exerting too much force.

3. Do not wear high heels when walking long distances. Wear thick-soled, elastic soft-soled shoes to reduce the impact on the knee joints and avoid wear and tear on the knee joints.

4. When participating in physical exercise, you should do warm-up exercises, gently stretch the knee joints, and allow the knee joints to fully move before participating in strenuous exercise. When doing leg stretching, do not lift your legs too high suddenly to avoid excessive strain on the knee joints. When practicing Tai Chi, do not squat too low and do not do several sets in a row to avoid excessive stress on the knee joints and possible injuries.

5. When riding a bicycle, you should adjust the height of the seat so that you can sit on the seat with your feet on the pedals and your legs straight or slightly bent. If the seat is too high or too low, or if you pedal hard when riding uphill, it will have an adverse effect on the knee joints.

6. When the knee joint is exposed to cold, blood vessels contract and blood circulation deteriorates, which often aggravates the pain. Therefore, you should pay attention to keeping warm in cold weather and wear knee pads if necessary to prevent the knee joint from getting cold.

7. People with knee osteoarthritis should try to avoid going up and down stairs, climbing mountains, standing for long periods of time, and lifting heavy objects as much as possible to avoid excessive load on the knee joints and aggravating the condition.

8. People with knee osteoarthritis should avoid excessive fatigue of the knee joints and perform appropriate functional exercises to increase the stability of the knee joints and prevent leg muscle atrophy. This can not only relieve joint pain, but also prevent the progression of the disease. Don't think that only rest and inactivity can protect the diseased knee joints. According to research, swimming and walking are the best exercises for people with knee arthritis. They do not increase the load-bearing capacity of the knee joint, but can exercise the muscles and ligaments around the knee joint. Secondly, sit-ups, push-ups, bridge-like arches, repeated exercises of raising and lowering the legs while lying on the supine bed, and imitating riding a bicycle are all good exercises for patients.
