Patellofemoral knee replacement

What is a patellofemoral knee prosthesis?

A patellofemoral knee prosthesis is a type of knee prosthesis used in individuals with specific knee issues primarily affecting the patellofemoral joint. The patellofemoral joint is located between the kneecap (patella) and the thigh bone (femur). This prosthesis is utilized when there is isolated wear or conditions limited to the patellofemoral joint, such as severe osteoarthritis or degeneration of the kneecap or a significant cartilage injury.

A patellofemoral knee prosthesis differs from a total knee prosthesis (TKP) where all parts of the knee joint are replaced. With a patellofemoral knee prosthesis, only the damaged patellofemoral joint is replaced while preserving the remaining knee joint. This type of prosthesis aims to reduce pain, improve mobility, and restore functionality to the patellofemoral joint.

During surgery

During the surgery, the damaged cartilage of the patellofemoral joint is removed and replaced with an artificial prosthesis. The prosthesis typically consists of a metal component that is placed on the femur and a plastic component that is attached to the back of the kneecap. These components allow for smooth movement of the patellofemoral joint without friction and pain.

After surgery

After the surgery, the patient will undergo a rehabilitation program to promote recovery. This may include exercises to strengthen the muscles around the knee joint and improve mobility. It is important to note that not all patients with patellofemoral problems are eligible for a knee prosthesis. A thorough evaluation by an orthopedic surgeon is necessary to determine if a patellofemoral knee prosthesis is the appropriate treatment option.
