The MAR at 15 years was 3.0% (2.8–3.2%). Age had a significant effect on MAR rates, with cumulative percent revision at 15 years for patients < 55 years old of 7.8% (95% CI, 6.5% to 9.2%) compared with 1.0% for those ≥ 75 years old (95% CI, 0.8% to 1.1%; P < 0.001).

For patients aged 70 years at implantation (mean age of implantation) LTRR was between 4·4% and 7·7%. For patients aged between 60 and 70 years, LTRR increased with decreasing age, reaching approximately 15% for both hip and knee replacement at 60 years, with greater risk in male than in female patients. Significant increase in LTRR was seen in younger men, with values 35.0% (30.9–39.1) seen in the youngest patient group (50–54 years)

The overall incidence rate of revision TKA was 367.3/100,000 person-years. The incidence in patients 50 years old or younger was extremely high. Incidence rate per 100,000 person-years: < 65 years (447.2), 65–74 years (363.7), ≥ 75 years (270.9)

Overall patient survivorship to 20-year follow up was only 26%. Patient survivorship at 20-year follow up was significantly higher in patients < 65 years of age in both cohorts (54% versus 15%, P < 0.001 modular tray cohort, and 52% versus 26%, P = 0.002 rotating platform cohort).

The risk of aseptic mechanical failure was 4.7 times higher (OR = 4.66, 95% CI, 3.77 to 5.76) in patients younger than 50 years of age, 2.1 times higher (OR = 2.09, 90% CI, 1.81–2.41) in patients 50–64 years compared with patients 65 years of age or older

There was a significantly different revision rate (P < 0.001) in the < 65 and ≥ 65 years age groups. For every 10-year increase in age the risk of revision decreases by 38% (95% CI, 33%–43%, P < 0.001).

Patients younger than 50 years at the time of surgery have a greater chance of requiring revision than of dying, those around 58 years of age have a 50:50 chance of needing revision, and in those older than 62 years the prosthesis will normally outlast the patient.

The 5-year survival rates were 92% and 95% in patients age ≤ 55 and 56–65 years, compared to 97% in patients who were > 65 years of age (P < 0.001) Overall risk of prosthesis failure > 3.7 years follow up: ≤ 55 years (5.0 [3.2–8.0]), 55–65 years (2.0 [1.4–2.9]) vs. > 65 years
