¹ The cumulative revision percentage using the competing risk method is shown in the figure.
² First revision of the femur or tibia component, regardless of whether a minor revision has already taken place. Therefor, the first three revision procedures were reviewed.
³ Only insert and/or patella exchange (including patella addition).
TKA: total knee arthroplasty; CI: confidence interval.
