Abstract
Introduction and importanceVery few reports addressed polyethylene tibial post and cone fractures requiring revision surgery. Up to our knowledge, this particular pattern of wear, involving 2 fracture areas simultaneously, has not been previously described.Case presentationA 70 year-old female developed a fracture involving both the tibial insert post and cone after a minor trauma after undergoing posterior-stabilized total knee replacement 4 years prior.Clinical discussionThis unique pattern of wear may occur even after minor trauma.ConclusionWe recommend having a low threshold to investigate minor trauma in this patient population, even years after undergoing primary knee arthroplasty.
