Alumina on alumina VS. All the included studies were of highly qualified methodology according to the quality assessment system, which contributes to the strength of conclusions drawn from the meta-analysis. The follow-up period ranged from 2 years to A year study versus ceramic-polyethylene on the contralateral hip. He found significantly lower linear penetration and three-dimensional wear with use of the highly cross-linked PE bearings than with the use of the conventional PE bearings.

Of these, citations were excluded after the first or second screening based on titles or abstracts, and 15 articles remained for full-text review. Alumina matrix composite VS. Eight studies[ 1415161718192021 ] enrolling a total of patients and THA surgeries were included in the final meta-analysis [ Figure 1 ]. Quality assessment of risk of bias summary in included studies. A radiographic analysis of loosening. Eight prospective randomized trials enrolling a total of patients and THA surgeries were identified. The ceramic bearing surfaces allows the use of larger head sizes and is more often implanted in younger patients, this may account for the finding that overall revision for dislocation is not significantly higher than other surfaces.
