Positive: gapping and or elicited pain above at or below joint line

Indicates: torn lateral collateral ligament

1

Bounce home test

Positive: knee does not go into full extension [Slight flexion remains]

2

Drawer test

Positive:
1. Gapping > 6 mm [tibia moves posterior] when the leg is pushed
2. Gapping > 6mm [Tibia moves anterior] when the leg is pulled

Indicates:
1. Torn posterior cruciate ligament
2. Torn anterior cruciate ligament

3

Lachman Test

Positive: gapping with the tibia moving away from the femur

Indicates: anterior cruciate ligament or posterior oblique ligament instability

4

Apprehension test for the patella

Positive: apprehension, distress of facial expression, contraction of quadriceps to bring patella back in line

Indicates: chronic patella dislocation or predisposition to dislocation

5

Patella femoral grinding test [a.k.a. Clark sign]

Positive: retropatellar pain and the patient is unable to hold the quadriceps contraction

Indicates: degenerative changes of the patellar facet and or within the trochlear groove (Chondromalacia patella)

Indicates: pain on medial side is medial meniscus tear. Pain on the lateral side indicates lateral meniscus tear

8

Apley Distraction Test

Positive: patient will point to side of pain

Indicates: pain on the medial side indicates medial collateral ligament tear. Pain on the lateral side indicates lateral collateral ligament tear

ROM

Flexion = 135°
Extension = 0
Internal rotation
External rotation

10

McMurray sign

Positive: clicking sound or pain by knee joint

Tear of the medial meniscus is positive on external rotation
Tear of lateral meniscus is positive on internal rotation
The higher the leg is raised during extension when positive is elicited, the more posterior the meniscal injury
