Flashcards in Knee special tests Deck (20)

Anterior Drawer, Lachman

Tests ACL


Posterior Drawer, Sag test (Godfrey's)



Valgus Stress Test

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


Varus Stress Test

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


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


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


Crossover Test

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


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


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


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


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


Posterolateral/ Posteromedial Drawer Test

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


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


McMurray's Appley's Compression and Distraction



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


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


Ober's Test

tests for IT band tightness


Clark's Sign or Grind Test




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


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
