Traumatic fracture of the polyethylene tibial post and cone in a posterior-stabilized total knee arthroplasty: A case report

INTRODUCTION AND IMPORTANCE: Very 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 PRESENTATION: A 70 year-old female...

Sumario:INTRODUCTION AND IMPORTANCE: Very 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 PRESENTATION: A 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 DISCUSSION: This unique pattern of wear may occur even after minor trauma. CONCLUSION: We recommend having a low threshold to investigate minor trauma in this patient population, even years after undergoing primary knee arthroplasty.
