Neglected Ipsilateral hip dislocation with acetabulum fracture and knee dislocation reconstructed with Dual mobility Total hip replacement & Hinged knee replacement; A case report

Abstract

We report the case of a 60-year-old male who presented with chronic pain and inability to bear weight on the right lower limb, two years after a road traffic accident and initial surgical management for acetabular and knee fractures. Examination revealed a dislocated right hip with proximal femoral migration, deformed femoral head, shallow acetabulum, and a subluxed right knee. After thorough evaluation, a two-stage surgical plan was adopted: Stage one involved a cemented total hip replacement with dual mobility cup and Wagner stem using a trochanteric osteotomy. Four weeks later, a cemented hinged total knee replacement was performed. Postoperatively, the patient was mobilized with full weight-bearing. This case highlights the successful staged reconstruction of a neglected hip dislocation with concurrent knee instability, enabling restoration of mobility and functional independence.
