Abstract: This systematic review compared 2 treatments for hip disease in active young patients: modern metal-on-metal total hip resurfacing and standard total hip arthroplasty. We conducted a literature search to identify relevant randomized and clinical controlled trials and included 968 patients from 4 trials in our analysis. Our results indicated increased rates of revision, femoral neck fractures, and component loosening among patients who received modern metal-on-metal hip resurfacing. No significant differences in the rates of mortality, dislocation, or deep hip joint infection were found between treatment groups. Hip function scores were similar between the 2 groups, but the resurfacing group showed higher activity levels. These results have provided insufficient evidence to determine whether modern metal-on-metal total hip resurfacing offers clinical advantages over standard total hip arthroplasty.
