Tibial tuberosity

Tuberositas tibiae

Definition

The tibial tuberosity is a bony prominence located on the anterior aspect of the upper end of the tibia. It acts as a boundary for the intercondylar area in the anterior direction and marks the starting point of the tibia's anterior border.

The tibial tuberosity can be divided into two parts: an upper smooth portion and a lower rough portion. The smooth part serves as the attachment site for the ligamentum patellae (or quadriceps tendon), while the rough part is located subcutaneously and separated from the skin by an infrapatellar bursa.
