Patella - Definition

Ask a question


The patella is a small flat triangular bone found on the anterior knee. The bone can be palpated beneath the skin. The patella allows the extension and flexion of the leg movements. Its posterior surface is in contact with the femur, giving strength to the quadriceps muscle. The patella articulates with the tibia through the patellar tendon and the femur through the patellofemoral joint and quadriceps tendon. The head is covered with cartilage.
