Catastrophic Failures of the Tibial Post in a Bicruciate Substituting Total Knee Prosthesis

Abstract

Failure of the tibial post in a bicruciate substituting total knee prosthesis is a rare but catastrophic complication. The authors report 2 cases of a fracture of the polyethylene tibial post with subsequent episodes of knee subluxation. Prompt recognition and early revision of these complications are associated with a favorable early outcome.
