Abstract
We set out to demonstrate the 10-year survivorship of the PFC sigma TKA in a young patient group.
Demographic and clinical outcome data were collected prospectively at 6 months, 18 months, 3 years, 5 years and 8-10 years post surgery.
The data were analysed using Kaplan Meier survival statistics with end point being regarded as death or revision for any reason.
203 patients were found to be ≤55 years at the time of surgery. Four patients required revision and four patients died. Another four patients moved away from the region and were excluded from the study.
A total of 224 knees in 199 patients (101 male and 98 females.) 168 patients had a diagnosis of Osteoarthritis and 28 with inflammatory arthritis. Average age 50.6 years range 28-55 years (median 51).
Ten-year survivorship in terms of revision 98.2% at ten years 95% confidence interval.
Our results demonstrate that the PFC Sigma knee has an excellent survival rate in young patients over the first 10 years.
TKR should not be withheld from patients on the basis of age.
