| Abstract: | Background In the United States, the obese population has increased markedly over the last four decades, and this trend continues. High
patient weight places additional stress on TKA components, which may lead to increased polyethylene wear, osteolysis, radiolucencies,
and clinical failure. Metal-backed tibial components and all-polyethylene tibial components in the general population have
comparable osteolysis and failure, but it is unclear whether these components yield similar osteolysis and failure in obese
patients. |
