Open Periprosthetic Knee Fracture: A Case Report and Review of the Literature.

INTRODUCTION

With the increase in knee and hip implants, these periprosthetic fractures will become more common especially as the population ages. Open periprosthetic fractures are rare and severe injuries and are more likely to be seen in high-energy injuries. They present challenges to the treating physician due to soft tissue damage, contamination of the existing implants, and the effects of polytrauma in the geriatric patient.

METHODS CASE REVIEW REPORT AND REVIEW OF LITERATURE

RESULTS

A 72-year-old woman was involved in a motor vehicle collision with multiple injuries including an open periprosthetic tibia and femur fracture. This was treated with initial washout and removal of loose tibial component with placement of a cement spacer. The knee was treated with staged revision using a protocol like that used after prosthetic joint infection. After complete soft tissue healing, the patient underwent successful revision with a megaprosthesis. The literature on open periprosthetic fractures is reviewed.

DISCUSSION AND

CONCLUSION

Open periprosthetic fractures present multiple challenges to the orthopedic surgeon. In the presences of poly trauma and soft tissue injury, we present an approach using staged surgery like that used for prosthetic joint infection.
