Flashcards in Knee special tests Deck (20):
1

Anterior Drawer, Lachman

Tests ACL

2

Posterior Drawer, Sag test (Godfrey's)

PCL

3

Valgus Stress Test

Test at O and 250-entire medial joint capsule and other restraining striations25 - isolate MCL

4

Varus Stress Test

Test at 0 and 250- LCL, lateral jont capsule, cruciate ligaments, 25 - isolate LCL

5

JointPlay of proximal tibiofibular syndesomsis

knee flexed, pt supine, grab and move fibula back and forth, stabilize tibia with other handanterior shift - damage to posterior ligamentposterior shift- damgage to anterior ligament

6

Slocum Drawer Test

-tests for rotational knee instability-internal rotation: ACL, anterolateral capsule, LCL, IT band, popliteus endon, posteroalteral complex, lateral meniscus-external rotation: MCL, anteromedial capsule, ACL, posteromedial capsule, pes anserine, medial meniscus

7

Crossover Test

Pt stands on involved leg.Pt cross uninvolved leg in front (ALRI) then to the back (AMRI)

8

Pivot Shift Test (Jerk TEst)

Tests for anterolateral knee instability Pt is supine, hip is in 30 degrees of flexion, tibia internally rotated, grab at foot and apply valgus force to knee,Knee is passivley flexed, look or tibia's position to reduce Jerk test, leg begins in flexion and is passively extended, look for anterior subluxation-ACL, anterolaeral capsule, LCL, biceps femoris, lateral meniscus, popliteus, posterolateral capsule

9

Slocum Anterolateral Rotary Instability (ALRI) test

Pt is side lying on flexed uninvolved hip and kneeExaminer places a valgus force to involved kneelook for clunk or instability as lateral tibial plateau sub luxes-ACL, LCL, anaterolateral capsule, arcuate ligament complex, biceps femoris tendon, IT band

10

Dial Test

External rotation test-posterolateral knee instabilitypt is supine, knees flexed and examiner externally rotates tibias-difference at 30 - isolated posterolateral corner-difference at 90 - isolated PCL-diffrence at both - PCL, posterolateral knee structures, posterolateral corner

11

External Rotation Recurvatum Test

Examiner lefts both legs by ends of feet and observe bilateral alignment of knees-look for difference in hyperextension, external femoral rotation, varus alignment between 2 knees

12

Posterolateral/ Posteromedial Drawer Test

Tibia externally rotated: posterolateral corner and PCLtibia internally rotated: PCL tear, oblique ligament, MCL, posteromedial capsule, semimembranosus

13

Reverse Pivot Shift

Examiner externally rotates tibia and flexes kneeKnee is passively extended till clunk is felt as tibia reduces on femur-posterolateral rotatory instability or trauma to posterolateral corner

14

McMurray's Appley's Compression and Distraction

Meniscus

15

Thessasly Test

Meniscus tearsPt stands flatfooted on involved legExaminer balances pt as pt rotates internally and externallyin first rotation knee is flexed at 5 degreesin 2nd rotation knee is flexed 20 degrees- complains of joint line discomfort, catching or locking

16

Noble's Test or Renne's Test

examiner passivley flexes and extends kneewhile holding IT band against lateral femoral condyletests for IT band friction syndrome

17

Ober's Test

tests for IT band tightness

18

Clark's Sign or Grind Test

Chrondamalcia

19

Apprehension

move patella as far laterally as allowed-laxity of medial retinaculum, patellar subluxation

20

Plica Test

pt supine in 90/90 examiner internally rotates tibia and moves patella medialthen extends the leg, feeling anteromedial capsule and for plica moving
