1

Knee Bony Palpation

patella

tibial tubercle

medial tibial plateau
medial femoral condyle

lateral tibial plateau
lateral femoral condyle

fibular head

2

Knee Soft Palpation

Quadriceps muscles
- rectus femoris
- vastus intermedius
- vastus medialis
- vastus lateralis

Bursae
- prepatellar bursa
- infrapetellar tendon
- superficial infrapatellar bursa

medial collateral ligament
lateral collateral ligament

medial mensicus
lateral meniscius

Pes anserine Area
- sartorius
- gracilis
- semitendinosus

gastrocnemius muscle

popliteal fossa

3

Knee ROM

Flexion 135°
Extension 0°

Internal Rotation
External Rotation

4

McMurray's Sign

( + ) clicking sound or pain by the knee joint

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

5

Medial Collateral Ligament Test
(Abduction Stress Test/Valgus Stress Test)

( + ) gapping and/or elicited pain above/at/or below joint line
( i ) torn medial colllateral ligament

6

Lateral Collateral Ligament Test
(Adduction Stress Test/Varus Stress Test)

( + ) gapping and/or elicited pain above/at/or below joint line
( i ) torn lateral colllateral ligament

7

Bounce Home Test

( + ) Knee does not go into full extension (slight flexion remains)

( i ) Diffuse swelling of the knee, accumulation of fluid due to possible torn meniscus

8

Drawer Test

a. ( + ) Gapping more than 6mm (tibia moves posterior) when the leg is pushed

a. ( i ) torn posterior cruciate ligament
- - - - - - - - - - - - - - - - -
b. ( + ) Gapping more than 6mm (tibia moves anterior) when the leg is pulled

bl ( i ) torn anterior cruciate ligament

9

Lachman Test

( + ) Gapping with the tibia moving away from the femur

( i ) Anterior cruciate ligament or posterior oblique ligament instability

10

Apprehension Test for the Patella

( + ) Apprehension, distress of facial expression, contraction of quadriceps to bring patella back in line

( i ) Chronic patella dislocation or pre-disposition to dislocation

11

Patella Femoral Grinding Test
(Clarke Sign)

( + ) Retropatellar pain and the patient is unable to hold the quadriceps contraction

( i ) Degenerative changes of the patellar facets and/or within the trochlear groove (chondromalacia patella)

12

Patella Ballottment Test

( + ) A floating sensation of the patella

( i ) A large amount of swelling in the knee

13

Apley Compression Test

( + ) Patient points to side of pain

( i ) Pain on medial side is medial meniscus tear. Pain on the lateral side indicates lateral meniscus tear

14

Apley Distraction Test

( + ) Patient points to side of pain

( i ) Pain on medial side is medial meniscus tear. Pain on the lateral side indicates lateral meniscus tear
