Abstract
Background
The European population is consistently getting older and this trend is expected to continue with fastest rise seen in those over 85 years old. As a consequence there will be more nonagenarians (over 90 years old) having lower limb arthroplasty.
Objectives
To compare the length of stay, readmission and one year mortality between nonagenarians and people aged between 70 to 80 years after having lower limb arthroplasty.
Methods
Retrospective review of patients electronic records over 90 years following total knee replacement (TKR) or total hip replacement (THR). The length of stay after surgery, 30 day readmission rate and one year mortality were compared with control group aged between 70 to 80 years who had lower limb arthroplasty during the same period.
Results
There were 31 nonagenarians with mean age of 91.6 years and the control group consisted of 31 patients with the mean age of 74.6 years. The average length of stay was 5 days in the nonagenarians compared to 4 days in the younger group. There was no difference in the 1 year mortality. 30 day readmission's was 16% in the older cohort and 5% in the younger. There was an increase in trend of nonagenarians having lower limb arthroplasty over the years.
Conclusions
There is increasing number of nonagenarians undergoing lower limb arthroplasty. Nonagenarians and those aged between 70 to 80 years have comparable length of stay and 1 year mortality but higher rate of readmissions after lower limb arthroplasty.
