The tibia is the medial bone of the (lower) leg (the fibula is the lateral bone).
The tibia articulates:
- with the femur proximally, forming the knee (tibiofemoral) joint.
- with the talus distally, forming the ankle (talocrural) joint.
- with the fibula laterally, forming the tibiofibular joints.

NOTES:

The tibia is much larger than the other bone of the leg, the fibula.
The medial malleolus of the distal medial tibia sits higher (more proximally) than the lateral malleolus of the distal lateral fibula.
There are actually two tibiofemoral joints: medial and lateral. The medial tibiofemoral joint is where the medial surface of the tibial plateau articulates with the medial condyle of the distal femur. The lateral tibiofemoral joint is where the lateral surface of the tibial plateau articulates with the lateral condyle of the distal femur.
