Fracture of the femoral component in cementless total knee arthroplasty.

abstract：:Breast cancers frequently metastasize to the skeleton and cause bone destruction. Tumor cells secrete factors that stimulate osteoclasts. The consequent osteolytic resorption releases active factors from the bone matrix, in particular transforming growth factor-beta (TGF-beta). The released factors then stimulate tumo...
