Abstract
Subchondral Insufficiency Fracture (SIF) of the femoral head has been observed in elderly women with osteoporosis. We present a rare case of subchondral insufficiency fracture of the femoral head complicated after total knee arthroplasty. Histological findings suggested osteonecrosis or SIF of the femoral head. MRI characteristics were considered to be useful for the differentiation between osteonecrosis and SIF. Several pathological conditions may be related to SIF of the femoral head, but its detailed pathogenesis is still unknown.
