The basic articulations:
- Flexion and Extension
- Internal and External Rotation
The Knee CAR (controlled articular rotation):
- Bend the knee into flexion and rotate the tibia to one direction at end range
- Maintain rotation and take the knee into extension
- While in extension, rotate the tibia in the opposite direction to end range
- Maintain the rotation and take the knee back into flexion
- Avoid moving the thigh (femur) when rotating
- Always express current end ranges
- Repeat again or in the opposite direction if desired
