Patients scheduled for primary hip arthroplasty at USBALO “Prof. Boycho Boychev” complete the nine-item Patient Health Questionnaire (PHQ-9) pre-operatively and at defined post-operative intervals. The study mirrors the knee-arthroplasty PHQ-9 cohort, enabling cross-procedure comparisons of mental-health trajectories after lower-limb joint replacement.
