The purpose of Total Hip Replacement Surgery is to remove the damaged and worn parts of the hip and replaces them with artificial parts, called prostheses, which will help make the hip strong, stable and flexible again.

For some patients, an acrylic cement called Polymethylmethacrylate (PMMA) will be used for the fixation. This cement has been used successfully by orthopaedists for over 25 years. It is a strong material, well-tolerated by the body and set or cures within 15 minutes after it is mixed. Before curing, the cement is pressure-injected and the implants are seated. Most patients are able to bear weight on the operated leg the day after surgery.

For other patients, the implants are able to be affixed to the bones without cement. Special surgical instruments are used to precisely prepare the bones so as to enable a press fit. To supplement this joining, supportive screws or pegs are often used. Bone is a living and growing tissue. If an implant coated with metallic beads to form a porous undersurface is placed in very close contact to living bone, tissues can grow into the pores, further locking the implant in place. Porous-coated hip prostheses have been used for many years and have shown excellent results in many patients.
