Diamond OJ, et al. - Researchers reviewed the clinical, radiological and patient-reported outcomes with the use of modular dual mobility articulation for revision acetabular reconstruction. They also probed whether the modular acetabular components of the dual mobility articulation increased the risk of fretting corrosion by measuring serum trace metal ion levels in a subset of these patients. An excellent option for the patient having revision hip surgery in the setting of recurrent instability or at high risk for instability was represented with dual mobility with cups with modularity. Good patient-reported outcome measures and a low complication and revision rate was provided in the findings.
