Component Fracture in the Kotz Modular Femoral Tibial Reconstruction System: An Under-Reported Complication

This study shows that fracture is an under-reported complication associated with the KMFTR stem. We identified an endoprosthetic component fracture rate of 12%. Patients with smaller stem diameter and longer resection lengths were more likely to sustain a stem fracture. Subsequent revision provides a durable means of reconstruction, with no significant loss of patient function.
