24 Passive Patellar Grind With the patient supine and Pain is a positive test finding
Test relaxed, you press the patella and indicates cartilage
against the femur with the damage to the patellofemoral
palm of one hand while joint
passively flexing the knee with
the other hand
Alternatively, you can perform
an active patellar grind test
With the patient supine and
relaxed, you cup the patella
between your thumb and
index finger pressing the
patella against the femur
Then have the patient tighten
the quadriceps
25 Lachman’s Test With the patient supine and Anterior translation of the
the knee flexed between 20 tibia greater than 2mm and
and 30 degrees more than the uninvolved
side with either a soft
Place your thumb just over endpoint or no endpoint is a
the tibial tubercle and the positive test and indicates
other fingers are wrapped anterior cruciate ligament
around the rest of the calf injury
The other hand is used to
grasp the thigh just above the
patella; the thumb of this
upper hand presses against
the femur through the
quadriceps tendon while the
other fingers wrap around the
posterior thigh
If the patient is properly
relaxed, the limb should feel
like a dead weight
Once adequately relaxed, you
pull forward on the tibia with
one hand while
simultaneously pushing
backward on the femur with
other hand in a reciprocating
manner
Assessing both the amount of
anterior translation of the
tibia with respect to the
femur and the quality of the
endpoint
