What joints are present at the knee?
Femero-tibial

Function of anterior + posterior cruciate ligaments:
Anterior: prevents femur sliding posteriorly on tibia.
Posterior: Prevents femur rolling forwards.
Function of collateral ligaments:
Taught during knee extension for stability
TCL = prevents abduction
FCL = prevents adduction

- Suprapatellar bursa
- Bursa between lateral meniscus + popliteus tendon.
Proximal tibiofibular joints:
- synovial joint
- Plane joint
- Slight gliding movement
Distal tibiofibular joints:
Fibrous
Little movement
Stabilises ankle
