Abstract

For press-fit (cementless) total hip arthroplasty, area of non-contact (gaps) between the bone and the implant may reduce the mechanical stability of the implant. Stability is essential for osteointegration and ultimately the long-term success of the implant. Therefore, it is necessary to assess the micromotion that occurs at the bone/implant interface and identify whether this micromotion is within an appropriate range to allow for successful osteointegration between the implant and host bone [1].
