ARTICLE HIGHLIGHTS
Research background

Treatment of complex distal femur fractures in the elderly is debated. Currently available techniques (i.e. retrograde nailing, plate and screws fixation, delayed knee replacement surgery) are plagued by poor outcomes. More recently, megaprosthesis have been used for treatment of major trauma and their use has been investigated in treatment of distal femur fractures as well.

Research motivation

There is a lack of short to long term outcomes studies on the use of megaprosthesis for treatment of complex distal femur fractures in the elderly.

Research objectives

The aim of this study is to critically review our clinical experience with usage of megaprosthesis for treatment of complex distal femur fractures in a series of 11 elderly patients.

Research methods

We conducted a retrospective review of 11 consecutive patients older than 85-years-old for treatment with knee megaprosthesis at our institution. Patients were followed-up on an average for 23 mo after surgery. Clinical and radiographical outcome measures were assessed. Mortality was also recorded.

Research results

No deaths were recorded in our case series. At the time of the last follow-up all patients were walking either independently or with walking aids. The average Oxford Knee Score at the time of the last follow-up was 36.8 points. The average Visual Analogical Scale score at the time of the last follow-up was 1.9 points.

Research conclusions

Knee megaprosthesis in the setting of complex distal femur fractures in elderly patients is a valid solution which is able to offer short operative times and hospital stays.

Research perspectives

Longer follow-up studies will be needed to further validate our results. Furthermore, case-controlled studies (i.e. magaprosthesis vs standard plate fixation) would be useful to compare clinical outcomes between these two techniques.
