The goal of this randomised controlled trial is to compare the success of two types of hip replacement in patients with hip arthritis. The main question it aims to answer is whether a new type of hip replacement (called a hip resurfacing) can be as successful as an existing hip replacement (called a total hip replacement). Patients will be given either the new hip resurfacing or the existing total hip replacement and researchers will compare their function, complication rate and physical activity.
Patient requires unilateral primary hip arthroplasty due to primary osteoarthritis, osteoarthritis secondary to e.g. trauma, avascular necrosis or developmental hip dysplasia, or inflammatory arthritis.
Patient is willing to comply with study requirements.
Patient plans to be available through 10 years postoperative follow-up.
Patient has a BMI greater than 40 kg/m².
Patient has active infection or sepsis (treated or untreated).
Patient has insufficient bone stock at the hip (>1/3 necrosis of the femoral head or large and multiple cysts) or in general as in severe osteopenia or osteoporosis (t-score < -2.5 as measured with BMD).
