Muscle Origins
Lateral condyle & proximal lateral tibial shaft
- 💪 Tibialis Anterior
- 💪 Extensor Digitorum (also from proximal fibula)
Posterior surface & interosseous membrane (distal two-thirds)
- Tibialis posterior
Posterior surface, inferior to soleal line (middle third)
- Flexor digitorum longus
Soleal line (posterior proximal tibia)
- Soleus
Muscle Insertions
Lateral condyle / posterior lateral tibia
- Popliteus
Medial condyle / posterior medial tibia
- Semimembranosus
Pes anserinus (anteromedial proximal tibia, distal to medial condyle)
- 💪 Sartorius
- Gracilis
- Semitendinosus
Shaft (anteromedial surface, distal third)
- 💪 Tibialis Anterior (distally on medial cuneiform & base of 1st metatarsal)
Tibial Tuberosity (via patellar ligament)
- Rectus femoris
- Vastus lateralis
- Vastus medialis
- Vastus intermedius
Notes
No other major muscles insert directly on the tibia itself. The tibialis posterior and soleus originate on the posterior surface of the tibia (and fibula/interosseous membrane) but insert primarily on the tarsal bones rather than the tibia.
