Other Terms: Tuberosity, Tuberosity of tibia, Tuberositas tibiae, Tubérosité tibiale
The tuberosity of the tibia often presents as a roughened protrusion on the anterior surface of the proximal tibia. Its more proximal half is typically smooth serving as the attachment site for the patellar ligament, which is another name for the distal part of the quadriceps tendon. The distal half of this bump is rough and subcutaneous in position.
Tuberosity derives from the Latin term tuber meaning a lump. The -osity ending denotes many or to be full of something. The term then literally translates as having lots of lumps.
