FIGURE Cumulative second revision percentage of total hip arthroplasty after a one-stage first revision in the Netherlands in 2007-2019 (n=9,895)
TABLE Cumulative second revision percentages
| Competing Risk¹ (95% CI) | Kaplan Meier (95% CI) | |
| 1-year second revision (%) | 7.7 (7.2-8.3) | 7.8 (7.2-8.3) |
| 3-year second revision (%) | 11.6 (11.0-12.3) | 11.9 (11.2-12.6) |
| 5-year second revision (%) | 13.8 (13.1-14.6) | 14.3 (13.5-15.1) |
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.
CI: confidence interval.
