TABLE Reasons for second revision within five years in patients who underwent a second revision after a one-stage first revision of a total hip arthroplasty by type of first revision in the Netherlands in 2007-2019

Major first revision¹ (n=696) Minor first revision² (n=417) Any type of first revision³ (n=1,144)
Reasons for second revision Proportion4 (%) Proportion4 (%) Proportion4 (%)
Infection 28.4 54.4 38.8
Dislocation 28.7 30.7 28.8
Loosening of acetabulum component 20.7 4.8 14.3
