Muscle atrophy is caused by long-term inactivity of injured limbs, which is a normal phenomenon and can be recovered through later exercise.

Please note the following points:

1. Even in bed, keep moving your toes hundreds of times a day, which will move with your muscles and reduce the degree of muscle atrophy.

2. According to the recovery situation, you can do leg lifts every day and appropriately increase the amount of exercise.

3. It is not recommended to use long-term bone medicine (about two months is recommended). The recovery of this situation mainly depends on your own later exercise.

4. At the same time, we should pay attention to joint bending exercise in time, usually starting about 40 days after operation, so as to avoid bending into a big problem in the future.

In a word, muscular atrophy is not a serious problem. It's back to normal now. I hope I can help you and wish you a speedy recovery.
