Tests For Plica

A

Tests for Plica Syndrome–mediopatella plica test

Position: supine
Joint angles: flex knee 30 degrees
Motion: push patella medially

Results:
1st indicator: pain as push patella medially which depresses the plica under the patella (medial femoral condyle)

If that does not illicit pain: strum finger in space medial to the patella and find a guitar string wire=plic [most have some discomfort there]

Varus Stress Test With knee in slightly flexed

Position:
Joint angles: 
Hand placement: 
Motion: 
Results: 
Positive:
A

LCL,
posterolateral capsule, arcuate-popliteus complex, ITB, bicep femoris tendon

Position: supine
Joint angles: knee slightly flexed to 30 degrees

Hand placement:

  • stand at side of table.
  • mobilizing hand: hold patient ankle proximal to malleolus between elbow and trunk to secure the leg.
  • stabilizing hand: distal medial femur (use fingers to palpate opening joint space on lateral side)

Motion: apply varus force to the knee by pulling the distal tibia medially while stabilizing the medial distal femur.

Results: Expect gapping on lateral side of knee joint and abrupt and firm ligamentous end feel.

Positive: loss of LCL integrity: increased gapping, not a firm ligamentous end feel, clunk as you release.

Q

Posterior Sag Sign
Godfrey Sign

Position:
Joint angles: 
Hand placement: 
Motion: 
Results: 
Positive:
A

PCL

Position: hookline
Joint angles: 
Hand placement: 
Motion: 
Results: PCL should be aligned with femur and prevent the tibia moving posteriorly against gravity

Positive: tibia will not be aligned with femur and will sag back if PCL deficient

high sensitive–ask her about this

DO THIS TEST FIRST: Creates false negatives on the posterior drawer test since it is already far back an false positives on the anterior drawer test since there is space for it to come back to neutral

26
Q

Posterior Drawer Test

Position:
Joint angles: 
Hand placement: 
Motion: 
Results: 
Positive:
A

PCL ***anterior fibers
arcuate popliteus complex, posterior oblique ligament, ACL

Position: Hookline
Joint angles: knee flexed 90 degrees
Hand placement: sit on patient foot to prevent slide to knee extension. hands around the tibia so that the heels of your hands rest on the medial and lateral tibial plataues with fingers wrapped around the medial and lateral joint spaces
Motion: push the tibia in a posterior direction until the slack has been taken up

Positive: PCL lost integrity

Mobility test: posterior glide of the tibia–posterior mobility of the femoral tibia joint

27
Q

Reverse Lachman Test

Position:
Joint angles: 
Hand placement: 
Motion: 
Results: 
Positive:
A

PCL ***posterior fibers
arcuate popliteus complex, posterior oblique ligament, ACL

Position: PRONE

28
Q

Slocum test

Position:
Joint angles: 
Hand placement: 
Motion: 
Results: 
Positive:
A
  1. for anteromedial rotary instability
    MCL, posterior oblique ligament, posteromedial capsule, ACL
    Position: supine, hookline
    Joint angles: 90 degrees of knee flexion, tibia ER (15 degrees)
    Hand placement: sit on foot to hold in ER. hand behind superior posterior tibia with thumbs on tibial plateaus palpating joint lines, take up the soft tissue of the gastroc posteriorly while thumbs on tibial plateaus anteriorly
    Motion: pull the tibia anteriorly on the femur
    Results: as we laterally rotate the leg the medial part of the tibia comes forward creating more tension on medial component of the knee joint and thus the test looks at anterior and MEDIAL stability.
    Positive: anterior movement occurs mostly on the medial side of the knee
  2. for anterolateral rotary instability
    ACL, posterolateral capsule, arcuate-popliteus complex, LCL, ITB (ITB stabilizes lateral aspect of every position)

Hand placement: sit on foot to hold in IR.
Motion: pull the tibia anteriorly on the femur
Results: as we medially rotate tibia the lateral part of the tibia comes forward creating more tension on the lateral component of the knee joint and thus looks at anterior and LATERAL stability.
Positive: anterior movement occurs mostly on the lateral side of the knee

29
Q

Lateral Pivot Shift Test = Test of Macintosh

Position:
Joint angles: 
Hand placement: 
Motion: 
Results: 
Positive: 
False negative:
A

ACL*posterolateral capsule, arcuate-popliteus complex, LCL, ITB

Position: supine
Joint angles: Hip is 20 degrees flexed, some abduction,
Knee is flexed 5 degrees

Hand placement: -hand at lateral tibial plateau near the fibular head -other around malleoli

Motion: Apply tibia IR and Valgus—-then flex the knee to 40 degrees

Results: feel what happens at the lateral tibial plateau
POSITIVE: knee feels unstable, there is a clunk with reduction:
—- the anterior lateral component of the tibia will sublux forward as you bring in the rotation with valgus to 40 degrees of flexion
—-ITB will become a flexor because it goes behind the axis of the knee joint and it will reduce the tibia: it will pull on the tibia that dislocated/subluxed back into position and the clunk can be heard

FALSE NEGATIVE: cases of ACL tear but negative lateral pivot shift test:

 1. ITB not intact
 2. meniscal tear
