A 1982 finite-element analysis study examining stress distributions in tibial components for total knee replacement, focusing on scenarios with deficient cancellous bone and comparing conventional versus custom salvage prosthetic designs.
When tibial bone stock is poor — whether in primary TKA with osteopenic bone or in revision with cavitary defects — use metal-backed trays to reduce cancellous stress; in revision cases with extensive bone loss, consider designs that bypass cancellous bone entirely and transfer load to the cortical shell.
