Introduction:
Periprosthetic patellar fracture after total knee arthroplasty (TKA) is a rare complication. Their management can be very challenging with unpredictable results. Literature analysis showed few articles about this complication, but no publication has described the management of open patella fracture around total knee arthroplasty.
Case Presentation:
We report a unique case of an open patellar fracture above a total knee arthroplasty, sustained by a 56-year-old female patient.
Conclusion:
Despite the poor outcome of operative management in patellar periprosthetic fracture, this approach should be considered for acute and post traumatic fractures in young patients with a good remaining bone stock.
