Femoral Metaphyseal Bone Damage Requiring High Distal Femoral Augmentation to Avoid Early Aseptic Femoral Loosening

Alexander Suren

Background

In revision add up to knee arthroplasty, zonal obsession strategies with a combination of expand, press-fit stems, and sleeves are prevalent. We hypothesized that tall distal femoral increase with diaphyseal press-fit stems leads to an expanded rate of early aseptic extricating which femoral metaphyseal sleeves move forward embed survival. Subsequently, we reflectively explored embed survival in connection to increase statures and sleeves.

Methods

A total of 136 patients with cruel clinical follow-up of 50 months (extend, 28-85) who experienced measured add up to knee arthroplasty and modification add up to knee arthroplasty with semiconstrained inserts between January 2012 and July 2018 were reflectively assessed. Embed survival with 4, 8, and 12 mm distal femoral expands was compared to no distal increase. In this way, a subgroup examination was performed for femoral sleeve implantation.

Conclusion

Higher rates of aseptic femoral extricating were distinguished for distal femoral expansion of 8 mm or more without metaphyseal sleeve obsession in semiconstrained inserts. In this way, in cases with femoral metaphyseal bone harm requiring tall distal femoral enlargement, metaphyseal sleeves ought to be utilized to maintain a strategic distance from early aseptic femoral extricating.
