Are there sesamoid bones in the knee?

Sesamoid in the knee: the patella The most easily found sesamoid bone is the patella, or the kneecap. It is embedded within the patellar tendon that attaches the quadriceps to the tibia. The patella provides an extra mechanical advantage to the thigh, helping extend the knee the last 30 degrees.

Why is the patella classified as a sesamoid bone?

The patella is the largest sesamoid bone in the body. Sesamoids act like pulleys, providing a smooth surface for tendons to slide over, increasing the tendon’s ability to transmit muscular forces. The sesamoid is a small nodular bone most often present embedded in tendons in the region of the thumb.

Is the patella the knee cap?

Overview. The patellofemoral (kneecap) joint is made up of two bones: the patella (the kneecap) and the femur (the thighbone). When the knee bends and straightens, the patella glides along a groove on the femur called the trochlea. Some people have differences in the way the kneecap and this bone fit together.

What’s the knee cap?

The kneecap (patella) is a small triangular bone. It is just one of the many parts that make up the knee joint. Some of the other parts are muscles, ligaments, and leg bones. The kneecap provides leverage for your muscles as they bend and straighten the leg.
