Young patients with osteoarthritis, rheumatoid arthritis, congenital hip dysplasia, and ankylosing spondylitis hip lesions have higher requirements for hip replacement prostheses due to their age and activity needs. Firstly, due to their young age, they require a long life span of the prosthesis. Secondly, young patients are more active and are likely to participate in physical labor and strenuous sports activities, and the range of motion of the joint is large, requiring that the mobility of the joint after replacement be large, not easily dislocated, and that the prosthesis be resistant to wear and tear. With the improvement of material technology and production process of artificial joint prosthesis, many options are available for young patients in terms of the service life and stability of the prosthesis. I. Total hip surface replacement Total hip surface replacement preserves the femoral head and neck structure without stress masking, with a large head and good stability, and the range of motion is close to normal after joint replacement. Metal-to-metal interface, good wear resistance, can reduce osteolysis and decrease prosthesis loosening. In addition, because the femoral head neck is preserved, it creates conditions for future joint revision. B. Total hip replacement with large head prosthesis The large head prosthesis has good stability and the range of motion of the total hip joint is close to that of a normal person after replacement. There are a variety of wear-resistant prosthetic interface options: metal-to-highly cross-linked polyethylene, ceramic-to-highly cross-linked polyethylene, metal-to-metal, and ceramic-to-ceramic. Third, the choice of wear-resistant interface prosthesis Wear-resistant interface prosthesis include: metal to high cross-linked polyethylene, ceramic to high cross-linked polyethylene, metal to metal, ceramic to ceramic. Highly cross-linked polyethylene to metal head, ceramic to highly cross-linked polyethylene reduces wear and tear and can reduce osteolysis. Metal-to-metal and ceramic-to-ceramic have lower coefficients of friction, greater resistance to wear, and lower incidence of osteolysis, thereby improving the survival rate of the prosthesis.
