Knee ROM

Knee Flexion Normal ROM

0-135 degrees

Knee Flexion endfeel

soft

Knee Flexion patient position

supine with towel under calf; patient flexes hip to 90 degrees and flexes knee. should have space between calf and table to observe extension

Knee Flexion stabilization

femur to prevent movement at the hip >90 degrees. (don't want to flex >90 degrees)

Knee Flexion axis of rotation

lateral epicondyle of the femur (palpate do not just eyeball)

Knee Flexion stationary arm

lateral midline of femur in line with greater trochanter

Knee Flexion moveable arm

lateral midline of fibula in line with lateral malleolus

Knee Flexion helpful hints

end of ROM occurs with resistance of if further ROM causes hip flexion. Must be able to get to zero in order to say they start at 0

Knee Extension Normal ROM

0 - 15 degrees

Knee Extension endfeel

hard.

if >5 degrees, is hyperextension

Knee Extension patient position

supine with towel under calf

Knee Extension stabilization

none

Knee Extension axis of rotation

lateral epicondyle of the femur

Knee Extension stationary arm

lateral midline of femur in line with greater trochanter

Knee Extension moveable arm

lateral midline of fibula in line with lateral malleolus

Knee Extension helpful hints

follow sequence - AROM followed by overpressure but do NOT give overpressure beyond 0 degrees.

use negative number if patient is unable to get 0 degrees of knee extension.

documentation of knee ROM as an arc of motion if possible
