Previous corrective osteotomies of femur and pelvis are a risk factor for complications following total hip arthroplasty in hip dysplasia.

Background: Modified anatomy of dysplastic hips, bone defects and previous operations make THA (total hip arthroplasty) in patients with hip dysplasia a technically challenging procedure.

Methods: One hundred and ten patients (mean 49.2 years of age, range 19-76, female:103, male:7) underwent 122 subsequent hip arthroplasties from 2012 to 2019.
