    Adverse Local Tissue Reaction due to Acetabular Corrosion in Modular Dual-Mobility Constructs
    (Elsevier, 2020-12) Sonn, Kevin A.; Meneghini, Michael; Orthopaedic Surgery, School of Medicine
    Dual-mobility (DM) bearings in total hip arthroplasty (THA) have been reported to reduce dislocation rates, especially in high-risk patients, and are being rapidly adopted in primary and revision THAs. However, this technology introduces additional interfaces that have the potential to result in unforeseen complications. We present a series of 3 patients with mechanically assisted crevice corrosion at the acetabular component–metal dual-mobility liner interface. Consequently, we urge judicious use and close clinical observation of this new, effective technology in THA.

    Early failure of sequentially annealed polyethylene in total knee arthroplasty
    (Elsevier, 2020-01-09) Sonn, Kevin A.; Meneghini, R. Michael; Orthopaedic Surgery, School of Medicine
    Improvements in the processing of polyethylene have led to a dramatic reduction in wear rates in total hip arthroplasty. This led to the adoption of modern highly cross-linked polyethylene in total knee arthroplasty (TKA). However, the differences in modes of wear and failure between total hip arthroplasty and TKA have tempered expectations regarding similar decreases in polyethylene-related complications in TKA. We present a case of early catastrophic failure of a modern sequentially irradiated and annealed highly cross-linked polyethylene insert only 5 years after contemporary cementless TKA.
