title: Broken Pieces of Circlage Wire Lying in Soft Tissue Envelope Around Knee Joint: A Case Report and Review of Literature.
abstract: BACKGROUND
  The migration of circlage wires used in tension band wiring construct of patella fractures in the posterior soft tissue envelope surrounding the knee joint has been rarely reported.
  
  
  METHODS
  A 60-year-old woman presented to us with pain over medial aspect of right knee joint. She underwent open reduction and internal fixation for a patellar fracture which she sustained 4 years back and subsequently underwent kirschner wire(k wire) removal for the same around 2 years back. X-rays of the knee joint shows that the circlage wire used in tension band construct which was left in place had broken into multiple pieces and was lying in the soft tissue envelope surrounding the knee joint and one piece migrate to the popliteal fossa. On examination patient did not had distal neuro-vascular deficit. The pain of the patient was due to the osteo-arthritic changes in her medial side of knee joint rather than broken wire pieces. Patient was advised to undergo total knee replacement along with subsequent removal of broken wires but patient refused for any type of surgery and is kept on regular follow up.
  
  
  CONCLUSIONS
  This case report summarizes a rare complication resulting from hardware failure used for fixing patella fractures and throws a light on potential unwarned complications due to broken wires along with early recogonition and removal of broken hardware by surgeons.
