Which bony landmark serves as an attachment for the ITB?

1. pes anserine

2. tibial tuberosity

3. gerdy's tubercle

4. gluteal tuberosity

The correct answer is: gerdy's tubercle

The iliotibial band (ITB) is a thick band of fascia that runs along the outside of the thigh and plays a crucial role in stabilizing the knee. The correct answer identifies Gerdy’s tubercle as the bony landmark that serves as an attachment point for the ITB. Gerdy’s tubercle is located on the anterolateral aspect of the tibia, just below the knee joint. When the ITB attaches here, it provides a critical point for transferring forces from the gluteus maximus and tensor fasciae latae muscles, thus aiding in knee stability during activities like running and walking. This attachment also allows for efficient movement and helps to prevent lateral knee pain. In contrast, the other choices refer to different anatomical landmarks that do not serve as direct attachment points for the ITB. The pes anserine is a location on the tibia where the tendons of three muscles attach, primarily serving hamstring function. The tibial tuberosity is an attachment point for the patellar ligament, while the gluteal tuberosity serves as an attachment point for the gluteus maximus muscle. Thus, while these other bony landmarks are important for their respective
