Polyethylene wear and pelvic osteolysis are the most common late complications associated with stable cementless total hip implants. This manuscript describes the diagnostic strategies and treatment algorithm used at the senior author's (C.A.E) institution for patients with wear and pelvic osteolysis. This evolving management strategy is based on our experiences and ongoing research. We discuss patient selection, the evaluation of acetabular liner wear, the diagnosis of pelvic osteolysis, the timing of revision, and treatment strategies. According to this algorithm, we revise asymptomatic hips with pending or complete wear-through of the acetabular liner. We also recommend revision for most symptomatic patients with pelvic osteolysis and for patients with large pelvic osteolytic bone defects or a documented increase in osteolytic lesion size in an area of the cementless acetabular component in which a load transfer between the implant and the surrounding bone is likely to occur.
