What does a cementless hip replacement entail?

Cementless fixation: Cementless hip replacements means placing the cup into the pelvis and the stem into the thigh bone by pressing them into place and initially relying on the tight fit to stabilize the implants. As time goes by the bone grows onto the implants due to their rough surfaces and holds them permanently in place. Cemented hip replacement relies on cement to hold the implants permanently in place.

Bone Ingrowth : Hip replacement surgery involves the placement of a femoral and acetabular implant to "replace" hip joint. Most prosthesis are implanted without cement, or "cement less"- meaning that the implant is designed to have the bone to grow directly onto the prosthesis. This is the most common hip implant design used. Discuss further questions with your orthopaedic surgeon.
