There is no evidence that the blood supply to the femoral head can be improved by exercise. However, weight-reducing exercises such as cycling and swimming have less impact on the condition and can be performed appropriately to ensure daily activity. When the blood supply to the femoral head is insufficient, weight bearing and walking need to be reduced. For unilateral hip joint lesion, the lesion side should strictly avoid weight bearing, and can support crutches, wear sciatic braces, and walk with a walker. If both hips are involved at the same time, they should be bedridden or wheelchair-bound. In order to guarantee the daily activity amount, you can choose sports with less pressure on the femoral head, such as cycling and swimming, but it does not have the effect of improving the condition. Patients with insufficient blood supply to the femoral head also need to abstain from alcohol, avoid the use of glucocorticoid drugs, and seek prompt medical attention. If the condition progresses, it needs to be treated by drug surgery.
