Q

Valgus Test

A

Patient suprine with knee slightly flexed (30 deg). Distal portion of leg abducted, knee pushed medially

+Test = increased laxity, pain

Indicates = Medial Collateral Ligament of Knee problem

KEY: If positive at 0 degree abduction, indicates joint capsule issue

2
Q

Varus Test

A

Patient supine, knee flexed slightly (30 degrees). Knee pushed laterally, distal leg pushed medially (adduction)

+Test = Pain, joint laxity

Indicated = Lateral Collateral Ligament of Knee problem

Key = if pain at 0 degree adduction, indicates joint capsule problem

3
Q

Anterior Drawer Test

A

Patient supine, knee flexed at 90. Doctor sits on foot, pulls tibia anteriorly

+Test = excessive translation (movement)

Indicates: ACL tear/rupture

4
Q

Posterior Drawer Test

A

Patient supine, knee flexed at 90. Doctor sits on foot, moves tibia posteriorly.

+Test = excessive translation (movement)

Indicates = PCL tear/rupture

5
Q

Lachman’s Test

A

Patient supine and knee flexed 10-30 degrees. Hand placed on thigh, the other placed on back of leg. Thigh hand pushes down while leg hand pulls tibia anteriorly.

+Test = increased laxity

Indicates = ACL tear/rupture

6
Q

McMurray’s Test (Lateral and Medial)

A

Patient supine, thigh and knee flexed. Hand on dital femur, hand on ankle

Lateral Meniscus – Varus force, ankle internally rotated. Bring leg into extension and lower to table listening for popping

Medial Meniscus – Valgus force, ankle externally rotated. Bring leg into extension and lower to table.

+Test = pop or click heard

Indicates = Possible tear of medial/lateral meniscus

7
Q

Apley’s Grind Test – Compression

A

Patient prone. Knee flexed to 90. Examiner applies force into knee while roating FOOT internally and externally

+Test = pain with rotation and/or compression

Indicates = possible meniscal injury, collateral ligament injury or both

8
Q

Apley’s Grind Test - Distraction

A

Patient prone with leg flexed to 90. Examiner applies upward traction (pulls) to leg and rotates

1) +Test = Pain with distraction/rotation

Indicates = Possible collateral ligament issue

2) +Test = relief of pain

Indicates = possible meniscus injury

9
Q

Patella-Femoral Grinding Test

A

Compress patella caudally into trochlear groove. Have patient tighten quads against resistance

+Test = crepitus or pain

Indicates = roughness of articulatimng surfaces (i.e. chondromalacia)
