In this work, we characterize integrin CD11c (αXß2) expression in periprosthetic tissues of 45 hip revisions. Tissues were retrieved from 23 ceramic‐on‐ultra‐high molecular weight polyethylene (UHMWPE), 20 metal‐on‐UHMWPE, and 2 metal‐on‐metal total hip arthroplasties (THAs). Capsular tissue retrieved during primary THA from 19 patients served as controls. We identified a system to identify important...
Large‐diameter metal‐on‐metal (MoM) bearings evolved from the success of hip resurfacing. These implants were used in revision surgery in cases with well‐fixed acetabular cups but loose or failed femoral stems, to avoid cup revision. Early data showed low rates of dislocation and potentially low wear profiles due to better fluid film lubrication. The risk of impingement was also thought to be low...
