Introduction And Importance:
Arterial injury is extremely rare after total knee arthroplasty.
Case Presentation:
We describe a 68-year-old woman with dislocation of total knee arthroplasty after falling from a height. She had a popliteal artery injury and a vascular bypass was performed in delay. The patient died of a second myocardial infarction 3.5 months after her first introduction to our center.
Clinical Discussion:
Due to the prominent risk of vascular injuries after dislocation in TKA patients, we recommend performing vascular evaluations using CT angiography for all patients.
Conclusion:
Any untreated vascular compromise in the setting of TKA dislocation may lead to devastating outcomes such as amputation and death.
