FIGURE Cumulative second revision percentage of total knee arthroplasty after a one-stage first revision in the Netherlands in 2007-2020 (n=8,240)
TABLE Cumulative second revision percentages
| Number at risk (n) | Competing Risk¹ (95% CI) | Kaplan Meier (95% CI) | |
| 1-year second revision (%) | 7,150 | 5.6 (5.1-6.1) | 5.6 (5.1-6.1) |
| 3-year second revision (%) | 4,620 | 11.7 (11.0-12.5) | 11.8 (11.1-12.6) |
| 5-year second revision (%) | 2,732 | 15.1 (14.2-16.0) | 15.4 (14.5-16.3) |
| 7-year second revision (%) | 1,490 | 17.4 (16.4-18.5) | 17.9 (16.9-19.0) |
¹ The cumulative revision percentage using the competing risk method is shown in the figure.
One-stage revision: A single revision procedure to change (insertion, replacement and/or removal) one or more components of the prosthesis (excluding patella addition).
CI: confidence interval.

¹ The cumulative revision percentage using the competing risk method is shown in the figure.
One-stage revision: A single revision procedure to change (insertion, replacement and/or removal) one or more components of the prosthesis (excluding patella addition).
Major revision: revision of at least the femur or tibia component.
Minor revision: only insert and/or patella exchange (excluding patella addition).
CI: confidence interval.
