Data presented as % (n) unless otherwise indicated.
EQ-5D dimensions, ambulatory aid, and assisted living were entered into a multiple logistic regression model with adjustments for sex and age.
EQ VAS, EQ-5D index, and OHS were entered into a multiple linear regression model with adjustments for sex and age.
Complete response chart for EQ-5D-5L dimensions is available (see Supplementary Table 3; Supplemental Digital Content 3, http://links.lww.com/CORR/A578).
Use of a cane or crutches, walker, or wheelchair.
Home care, serviced apartment, nursing home, or equivalent; EQ = European Quality of Life; OHS = Oxford Hip Score; PJI = prosthetic joint infection.
