Introduction:
Knee arthrodesis following failed total knee arthroplasty is a viable limb salvage option, and this procedure is reserved for failed two-stage revision surgery in severe comorbid patients with irreparable extensor mechanism disruption, severe instability, and extensive soft tissue loss. Knee arthrodesis using a dual-plate construct has been scarcely reported. We report a case of knee arthrodesis using a dual-plate construct in a male in his 20s who presented to us with a broken distal femur megaprosthesis.
Case Report:
An anterior midline incision was given. The cement mantle and broken prosthetic components were removed. The bone surfaces were freshened up and fixed using two orthogonal locking plates. After 4 months, there was a solid fusion in the knee, and the patient started walking independently with a short limb gait. The patient was advised limb lengthening for a shortening of 3 cm, but he denied it and managed with a shoe raise. After 4 years, he was pain free, and radiographs revealed a solid knee fusion. The patient was fully satisfied with the procedure, and he resumed manual work.
Conclusion:
This case report revealed that knee arthrodesis using a dual-plate construct is an economically viable salvage option for failed distal femur megaprosthesis.
