Case:
Debonding of the tibial component of total knee arthroplasty is a known complication that is typically treated with revision surgery, most commonly revision to a metal-backed tibial component with or without stems. Here, we present 3 cases of tibial component debonding revised to all-polyethylene tibial components with a cement-in-cement technique.
Conclusion:
In instances of tibial component debonding, if specific criteria are met, revising to an all-polyethylene tibia with retention of the primary cement mantle is an alternative to revision surgery with cement extraction and implantation of a modular metal-backed tibia.
