Abstract
The use of the distal femoral replacement (DFR) has grown in recent years. Historically, this procedure was reserved for malignancy and complex revision cases with relative success. In recent years, complex reconstruction cases have had relative success. DFR has been associated with a range of complications including anterior knee pain, patellar instability, limitations in knee motion, and rotational instability that are sequelae of altered patello-femoral mechanics. Thus, subsequent dysfunction may require revision. To our knowledge, no surgical technique to correct DFR patello-femoral maltracking has been demonstrated in current literature. We present a surgical technique for DFR patello-femoral maltracking corrected surgically with femoral component revision and femoral stem retention.
