About this trial
This study will compare postoperative pain, health related quality of life (HRQoL), function, rehabilitation, urinary incontinence, muscle atrophy and component positioning in total hip arthroplasty (THA) using the posterolateral approach (PLA) or the direct superior approach (DSA). In addition, the CT images will be used to validate a new metal artefact reduction technique.

Treatment groups
Trial outcomes
Primary outcomes
Hip disability and Osteoarthritis Outcome Score - Physical Function Short Form
Evaluation symptoms and shortcomings in patients with hip complaints, 0-100 points, in which a higher score indicates less complaints
Secondary outcomes
Numeric Rating Scale (NRS)
Pain scoring on a 10-point Likert scale: 0 no pain to 10 worst thinkable pain
Short Form-12 (SF-12)
general health status, scored on 101-point Likert scale, 0 being worst health to 100 being ideal health
Hip disability and Osteoarthritis Outcome Score (HOOS)
evaluates symptoms and shortcomings in patients with hip complaints 5-point Likert scale, in which a higher score means less symptoms
Euro Quality of Life (EQ-5D)
measures health-related quality of life using 5 domains, questions scored on a 0-100 scale, the higher the score the better the quality of life
