A 38-year-old member asked:

Could the entire femur bone be replaced along with a total knee replacement?

Yes: Replacing the entire femur can be done, but it is rarely needed. Only patients with extensive cancer or many failed operations on the femur, might need it replaced completely.
Dr. Gwo-Chin Lee
Orthopedic Surgery 23 years experience
Yes: Rarely, in cases when there are no other limb salvage options, a total femoral replacement which is a hip joint joined by a segmental metal femur and capped by a hinged knee replacement can be performed.
Dr. David Fisher
Orthopedic Surgery 39 years experience
In certain cases: There are total femur implants that include hip and knee replacements with a metal femur. These are used for unusual cases such as tumors or severe femoral bone destruction.

Femur bone: In a knee replacement only the most distal aspect of the femur is replaced along with the proximal tibia and underlying portion of the patella. In extreme situations such as bone/soft tissue cancer that involves the femur shaft or infection can the entire femur bone be replaced. Even then the hip region may be salvaged. Choices are metal implants or cadaveric bone. Evenutally we will have scaffol.

Rare,rare,rare,rare: Tka is a resurfacing of the femur, tibia, and patella. Only with significant revisions or tumor reconstructive surgeries will a larger portion of the femur be replaced. Beyond this, custom implants are used.
