- The effects of elevated levels of metal ions in patients who have undergone metal-on-metal total hip arthroplasty are not fully understood.
- The effects of femoral head size on serum metal-ion levels have been the subject of conflicting reports, and further investigation is needed to evaluate the impact of acetabular and femoral component alignment.
- The conduct of clinical trials of metal-on-metal total hip arthroplasties has been inadequate as few investigators have used a randomized controlled design to compare metal-on-metal bearings with other bearing surfaces.
- Additional clinical research needs to include appropriate validated patient-reported outcome measures, activity monitoring, and health economics.
