Cementation of a Metal Dual Mobility Liner in Patients Undergoing Revision Total Hip Arthroplasty.

Background: Dual mobility liners for primary and revision total hip arthroplasties can lead to decreased dislocation and revision rates. However, there are a lack of data analyzing their utilization when cementing into well-fixed acetabular components in a variety of scenarios. Therefore, the purpose of this study was to examine cementation of dual mobility liners into well-fixed existing acetabular components from previous hip procedures, into new acetabular components, or directly into the acetabulum without prior implants.

Does Preoperative Statin Exposure Reduce Prosthetic Joint Infections and Revisions Following Total Joint Arthroplasty?

Introduction: The pleiotropic effects of statins extend beyond managing cardiovascular health and are suggested to modulate Staphylococcus aureus biofilm formation with prosthetic joint infection (PJI) reduction. However, a large analysis of statin use prior to total joint arthroplasty (TJA) to determine infection and revision risk is lacking. We specifically evaluated: 90-day to two-year (1) prosthetic joint infection (PJIs); (2) revisions; and (3) respective risk factors.
