Colizza et al. report minimum 10-year outcomes of cemented posterior stabilized TKA with metal-backed tibial components in 120 patients (165 knees), evaluating clinical scores, implant survival, polyethylene wear, and osteolysis at a mean follow-up of 10 years 8 months.
When counseling patients before cemented PS-TKA, this study supports quoting >10-year survivorship above 96% and near-zero risk of revision for wear or osteolysis with a conforming, cemented metal-backed design — and reinforces why radiolucent lines around a well-fixed metal-backed tibial component warrant observation rather than alarm, given their dramatically lower prevalence versus all-polyethylene designs.
