Proximal Tibiofibular Fracture Following Unicompartmental Knee Arthroplasty: A Case Report and Literature Review.

INTRODUCTION

Periprosthetic fractures following unicompartmental knee arthroplasty (UKA) are a relatively rare but clinically significant complication. Among these, proximal tibial and fibular fractures are even more uncommon. If not promptly and effectively treated, such fractures can significantly compromise the outcomes of UKA and the long-term survival of the prosthesis.

CASE: A 64-year-old female patient suffered a proximal tibiofibular fracture after accidentally falling following a UKA.

MANAGEMENT AND OUTCOMES: We performed an open reduction and internal fixation (ORIF) for the femoral fracture. One year postoperatively, follow-up examination indicated good fracture healing, stable prosthesis, and satisfactory knee joint range of motion, with no reported pain.

CONCLUSION

The treatment of proximal tibiofibular fractures around the prosthesis after UKA should be based on the specific fracture location and type, the stability of the prosthesis, and the overall health condition of the patient, such as the presence of osteoporosis. Surgical intervention remains a viable option for treatment.
