Stage 0 and 1 femoral head necrosis can be slowed down by injecting PRP, but it can’t cure the necrotic femoral head, it can only alleviate the symptoms, usually 1 to 3 courses of injection can relieve the symptoms. After injection, PRP can release growth factors, promote the proliferation of osteoblasts, and also inhibit osteoclast formation and bone resorption. PRP can accelerate the proliferation and differentiation of bone marrow mesenchymal stromal cells, helping the femoral head to repair the necrotic part and play a therapeutic role. Although PRP treatment for necrosis of the femoral head can have a better effect, it needs to be persisted for a long time, and should be injected according to the course of treatment under the guidance of the doctor. Necrosis of the femoral head can go to the hospital to clarify the stage of necrosis and choose the correct treatment plan.
