Hip arthroplasty after femoral osteotomy

Osteotomy of the proximal femur is performed to treat numerous hip pathologies in order to improve the load axis of the coxofemoral joint, thus improving coverage of the femoral head; despite this, arthrosis-related pathology may progress, and this nearly always results in hip arthroplasty. Many authors report that the time interval between osteotomy and arthroplasty is approximately 5 to 10 years. It is the purpose of this study to evaluate the complications and the clinical and radiographic results of hip arthroplasty performed after proximal femoral osteotomy, comparing them with a control group for hip arthroplasty without previous osteotomy.
