Femoral head replacement is mostly used to treat severe femoral head necrosis, traumatic osteoarthritis or severe degenerative osteoarthritis, and femoral neck fractures in the elderly, etc. Femoral head replacement is also advocated. It takes about 3 days after femoral head replacement to get up and move around gradually, but it usually takes 2-3 months to restore normal walking ability. In the early stage after femoral head replacement, you need a walker to protect you from getting out of bed, and you can walk normally only after the bone grows into the prosthesis. Avoid walking long distances and strenuous exercise after femoral head replacement, as this may accelerate the wear and tear of the prosthesis and shorten its life span. In addition, avoid cross-legged and cross-legged after femoral head replacement, as this will increase the risk of dislocation.
