Fig. 2From: Retention of metals in periprosthetic tissues of patients with metal-on-metal total hip arthroplasty is reflected in the synovial fluid to blood cobalt transfer ratio in the presence of a pseudotumourMetal concentrations in whole blood (WB), synovial fluid (SF) and synovial soft tissue (ST). The highest local metal concentrations were found in the synovial soft tissue followed by synovial fluid and blood. The distribution of chromium was different between tissues showing local accumulation of chromium in the synovial soft tissueBack to article page
