Outcomes of total hip arthroplasty after failed free vascularized fibular grafting for osteonecrosis of the femoral head
Total hip arthroplasty (THA) after vascularized fibular grafting (VFG) is technically demanding with poorer outcomes compared to primary THA in patients with osteonecrosis of the femoral head (ONFH). The purpo...

Delay of total hip arthroplasty to advanced stage worsens post-operative hip motion in patients with femoral head osteonecrosis
Osteonecrosis of the femoral head (ONFH) is commonly detected in young patients and most surgeons tend to delay total hip arthroplasty (THA) until the end stage of the disease. We hypothesised that post-operat...
