FIGURE Funnel plot of proportion of hip revision arthroplasties within one year after a total hip arthroplasty per hospital in the Netherlands in 2018-2022 (n=159,661)


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.

The mean 1-year revision percentage is 1.81 in the Netherlands in 2018-2022.
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 2018-2022 (n=159,661)


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.

The mean 1-year major revision percentage is 1.01 in the Netherlands in 2018-2022.
Control limits indicate the plausible range of outcome if all hospitals perform equally well.
