Usually, you can't do strenuous exercise after knee joint injury, which will only make the knee joint wear more serious, thus aggravating the condition. General doctors will also choose to let patients reduce exercise and wait for recovery. At first, you can choose physical therapy to help the blood circulation of the knee joint, such as hot compress or massage. After the treatment period, you can try to do some simple exercises that do not cause serious wear on the knee joint, such as swimming and cycling.
In the recovery period, you can try swimming, with less load on the knee joint, which can also effectively exercise the muscles of lower limbs and improve the coordination of the whole body. Some people think that cycling may increase the damage to the knee joint, but it is not. This kind of exercise is very suitable for people with poor knee joints who need exercise. But when riding, try to choose flat ground or places where there are not too many cars. Don't suddenly accelerate or decelerate during riding, just keep riding at a constant speed, and relax your knees and lower limbs in time after riding training to promote blood circulation.
Of course, for those who have no knee problems, we should also do a good job of prevention. Exercise more quadriceps femoris on weekdays to maintain the normal function of knee joint, while obese people should lose weight scientifically to avoid being overweight and increase the burden on knee joint, otherwise it will easily cause knee arthritis, especially for middle-aged and elderly people. Don't be brave when moving things on the stairs. If you carry it hard, it will also cause some damage to your waist and knees. If young people feel unwell during exercise, they must stop immediately to avoid getting worse.
