With the gradual increase in public awareness of hip replacement surgery and the geometric increase in surgical volume, more and more attention is being paid to the selection of the prosthetic interface. Patients often inquire about the frictional interface of hip prostheses, and in general, the hip prosthesis interface includes metal-to-metal, ceramic-to-ceramic, ceramic-to-polyethylene, metal head-to-polyethylene, and metal-to-ceramic. Art Sedrakyan, an American physician from Weill Medical Collge in New York, published an article in the British Medical Journal BMJ, November 2011, comparing the advantages and disadvantages of different joint interfaces.
