📌 Iliotibial Band Anatomy
- The iliotibial band (ITB or IT band) is a thick band of fascia along the lateral aspect of the thigh, representing a thickening of the fascia lata.
Distal Insertions
- At least 5 distal insertions have been described around the lateral knee, attaching to the distal femur, patella, proximal tibia, and joint capsule.
✅Superficial Layer
- Main tendinous component
- Inserts onto Gerdy's tubercle on anterior lateral tibia
✅Deep Layer
- Attaches superficial layer to lateral supracondylar tubercle of femur
- Blends into intermuscular septum at distal femur
✅Capsulo-Osseous Layer
- Situated deep and posterior to deep layer
- Forms a sling over lateral femoral condyle
- Inserts onto tibial tuberosity posterior and proximal to Gerdy's tubercle
- Some consider it the same as the anterolateral ligament
