TIBIAL TUBERCLE FRACTURES |
 | | The extensor mechanism consists of the tibial tubercle, the patellar tendon, the patella, the quadriceps tendon, and the quadriceps muscle. |
 | | As the quadriceps muscle contracts (shortens), it pulls on the quadriceps tendon, the patella, the patellar tendon, the tibia tubercle, and the tibia to move the knee from a flexed (bent) position to an extended (straight) position. |
 | | Tibial tubercle fractures usually occur in adolescents and typically occur at the growth plate of the proximal (upper) tibia. |
