This prospective study compares the prevalence of MRI detected adverse local tissue reactions (ALTRs) in metal-on-polyethylene (MoP), metal-on-metal hip resurfacing arthroplasty (HRA), and ceramic-on-polyethylene (CoP) total hip arthroplasty subjects. Images acquired at four time points with a 1-year interval showed a higher prevalence of ALTRs in the HRA than CoP or MoP subjects. Self-assessed symptomatology scores did not significantly differ by implant type at follow-up, indicating that ATLRs can be clinically silent. This study permits better understanding of the natural history of ALTRs complicating hip arthroplasty.
