Evidence from the study, which was published in the May issue of the Journal of Bone and Joint Surgery, suggests that 96 percent of the 124 cementless metal components assessed remain securely fixed in place 20 years post surgery. These components were designed with a porous structure to allow bone to grow into the surface in the hopes of achieving long-term fixation.
However, the study also found that the plastic lining of the metal shell of the implants had worn enough that repeat, but less involved, surgery was required or recommended in nearly 20 percent of the patients sampled.
