»:
The true incidence of pseudotumors in association with total joint arthroplasty is underestimated.
»:
Pseudotumors occur with metal-on-metal, metal-on-polyethylene, and metal-on-ceramic articulations.
»:
Metal ion levels should not be the only factor in decision-making regarding revision surgery.
»:
Revision surgery is only indicated in symptomatic patients with clinical and radiographic findings and elevated metal ion levels.
»:
Revision to a non-metal articulation is strongly suggested.
