With certain concerns recently reported on metal-on-metal bearing couples in total hip
arthroplasty, this study's objective is to review the current knowledge concerning release of …

Background: Despite the renewed interest in metal-on-metal implants in the past two
decades, the underlying wear mechanisms and biological effects are still not fully …

Background Pseudotumor-like periprosthetic tissue reactions around metal-on-metal (MM)
hip replacements can cause pain and lead to revision surgery. The cause of these reactions …

We present a series of 35 patients (19 men and 16 women) with a mean age of 64 years
(36.7 to 75.9), who underwent total hip replacement using the ESKA dual-modular short …

Peri-articular soft-tissue masses or 'pseudotumours' can occur after large-diameter metal-on-
metal (MoM) resurfacing of the hip and conventional total hip replacement (THR). Our aim …

Aim To describe the histopathology of localised adverse reactions to metal debris (ARMD)
seen in association with failed metal on metal (MoM) hip arthroplasties. The nature of …

Background To address the long-term problems of bearing surface wear and osteolysis
associated with conventional metal-polyethylene (M-PE) total hip arthroplasty (THA), metal …

Background Although pseudotumors have been reported in 32% of asymptomatic metal-on-
metal hips, the natural history of asymptomatic pseudotumors is unknown …

The incidence of pseudotumor formation has been reported to be 1% in patients with metal-
on-metal resurfacing arthroplasties. This complication is not exclusive to these patients. We …

Purpose To determine the prevalence of magnetic resonance (MR) imaging abnormalities
after metal-on-metal total hip arthroplasty and to determine whether presence of symptoms …
