Abstract
A total of 6275 consecutive TKA patients were divided into three groups based on their age: <55, 55-70 and >70 years. There was a statistically significant difference in the change in WOMAC score (32 vs 31 vs 26, P<0.001) and Knee Society Score (78.9 vs 76.0 vs 69.0, P<0.001) favoring the younger populations. However, the revision rate was higher in the younger patients with a Kaplan-Meier survivorship at 5 years of 95.5%, 97.2% and 98.1% and at 10 years of 92.2%, 95.9% and 97.6%. Infection was the most frequent cause for failure in all groups although aseptic loosening and instability accounted for the increased revision rate in the younger patients. Younger patients may experience slightly better clinical outcomes following TKA but lower survivorship, when compared to older patient populations.
