Congenital hip dysplasia often requires surgical interventions in younger adults. 3D-navigated, robotic-assisted surgery for total hip arthroplasty may be beneficial in cases of pseudo-acetabulum and preceding treatments (Chiari Pelvic osteotomy) due to better pre-surgical planning and higher levels of precision associated with the technology, which may be associated with positive effects regarding short-term and long-term clinical outcomes. Here, we report the case of a 26-year-old Caucasian woman with a Crowe-IV dysplastic hip and pseudo-acetabulum. Earlier interventions included Chiari pelvic osteotomy, femoral osteotomy and femoral lengthening, which did not improve pain and function in the longer term. The surgical approach via robot-assisted surgery lead to positive outcomes in the short-term (four months post-surgery) and medium-term (17 months post-surgery) in this specific case.
