TABLE Cumulative 1-year revision percentage of primary total hip arthroplasties by type of revision in the Netherlands in 2015-2019 (n=153,643)
Cumulative 1-year revision percentage | ||
Competing Risk (95% CI) | Kaplan Meier (95% CI) | |
Any type of revision¹ | 1.9 (1.8-1.9) | 1.8 (1.8-1.9) |
Major revision² | 1.1 (1.0-1.1) | 1.0 (1.0-1.1) |
Minor revision³ | 0.8 (0.7-0.8) | 0.8 (0.7-0.8) |
¹ Any type of revision includes minor and major revisions as well as revision procedures that could not be classified as minor or major revision.
² Revision of at least the acetabulum or femur component.
³ Only inlay and/or femoral head exchange (including DAIR procedures).
THA: total hip arthroplasty; CI: confidence interval.

In 2015-2019, 1,901 (1.2%) primary THAs were implanted in patients who died within one year after the primary procedure.

FIGURE Funnel plot of proportion of hip revision arthroplasties within one year after a total hip arthroplasty per hospital in the Netherlands in 2015-2019 (n=153,576)
Please note: The proportions of revisions within 1 year per hospital were adjusted for casemix factors age, gender, ASA score, BMI, smoking, charnley score and diagnosis (osteoarthritis versus other).
THA: total hip arthroplasty; CL: control limits; CI: confidence interval.
The mean 1-year revision percentage is 1.9 (95% CI: 1.7-1.9 ) in the Netherlands in 2015-2019.
Control limits indicate the plausible range of outcome if all hospitals perform equally well.

FIGURE Funnel plot of proportion of hip major revision arthroplasties within one year after a total hip arthroplasty per hospital in the Netherlands in 2015-2019 (n=153,574)
Please note: Major revision is defined as revision of at least acetabulum or femur compenent.
Please note: The proportions of revisions within 1 year per hospital were adjusted for casemix factors age, gender, ASA score, BMI, smoking, charnley score and diagnosis (osteoarthritis versus other).
THA: total hip arthroplasty; CL: control limits; CI: confidence interval.
The mean 1-year major revision percentage is 1.1 (95% CI: 1.0-1.1) in the Netherlands in 2015-2019.
Control limits indicate the plausible range of outcome if all hospitals perform equally well.

¹ Revision of at least the acetabulum or femur component.
² Only inlay and/or femoral head exchange (including DAIR procedures).
³ Any type of revision includes minor and major revisions as well as revision procedures that could not be classified as minor or major revision.
4 One patient may have more than one reason for revision. As such, the total proportion is over 100%.
