Patient and Radiographic Factors Help to Predict Metal-on-Metal Hip Resurfacings with Evidence of a Pseudotumor
Background: The role of radiographs in the follow-up of patients with metal-on-metal hip resurfacing (MoMHR) implants is unclear. We investigated whether a combination of patient and radiographic factors predicted MoMHRs with evidence of a pseudotumor.
Patient Factors (Table I)
Compared with the nonpseudotumor group, the pseudotumor group was younger (p = 0.0286), was more commonly female (63.9% versus 38.2%; p < 0.001), and had a longer follow-up time (mean, 5.8 versus 4.8 years; p < 0.001).
