Increased Mortality in Metal-on-Metal versus Non-Metal-on-Metal Primary Total Hip Arthroplasty at 10 Years and Longer Follow-Up: A Systematic Review and Meta-Analysis.
PLoS One. 2016 Jun 13;11(6):e0156051. doi: 10.1371/journal.pone.0156051. eCollection 201638 randomized controlled trials and 9 observational studies were included in this systematic review and meta-analysis to compare mortality and morbidity rates between metal-on-metal total hip arthroplasty (MOM THA) and non-metal-on-metal THA (non-MOM THA). Results of the meta-analysis indicate no significant differences in mortality rate within 5 years, or from 5-10 years. However, mortality rate was significantly higher among MOM THA groups compared to non-MOM THA groups in studies with >10-year follow-up. Additionally, a trend towards a greater rate of surgical revision was observed in the MOM THA group.
