The presence of advanced avascular
necrosis with femoral head collapse, poor bone stock, and advanced age should prompt the surgeon to discuss arthroplasty as the optimal treatment .
used autologous chondrocytes seeded into devitalized allogenic meniscal slices to regenerate a longitudinal tear in the avascular
portion of the meniscus in a pig knee injury model.
The pathogenesis of avascular
necrosis of femoral head (AVNFH) has not been fully understood.[sup],, The AVNFH typically presents in the young adults and will quickly progress to femoral head collapse and arthritic changes in the absence of treatments.[sup] Therefore, hip joint preservation surgery should be considered to prevent the collapse of the femoral head or at least postpone the need for a hip arthroplasty.[sup], The interventions include core decompression, osteotomies, and nonvascularized or vascularized bone grafting.[sup] However, osteotomies and bone grafting can cause severe trauma, which further undermines the femoral head blood supply system and worsens the ischemic conditions in the femoral head.
necrosis is the death of bone tissue due to a lack of blood supply.
