AROM defines the range of motion through which the patient can actively move with the help of the muscles acting over that joint.
The goal of AROM is to detect possible symptoms like pain and to determine their location, quality and intensity. Furthermore will you be able to see how freely your patient can move in a specific joint, while you are looking for compensatory strategies to achieve that movement.
The standard values for AROM movements in the knee joint are:
Flexion: 0°-135°
Extension: 0°-15°
Medial rotation of the tibia on the femur: 20° to 30°
Lateral rotation of the tibia on the femur: 30° to 40°
