Influence of the tibial stem design on bone density after cemented total knee arthroplasty: a prospective seven-year follow-up study

Abstract

We prospectively measured the changes in bone mineral density (BMD) in the proximal tibia of 20 total knee arthroplasties, ten with cruciform stems and ten with cylindrical stems. The measurements were made one, four and seven years after surgery. We observed a uniform density decrease in three regions of interest from one to seven years of follow-up… (More)
