Special Tests Flashcards
Test(s) for ACL Injury?
Lachman
Anterior Drawer
Pivot Shift
Describe how you would carry out the Dial Test and what a positive diagnoses indicates:
Posterolateral Knee Instability (PLC)
Patient lying prone, cup both heels of the feet then flex knee to 30. Apply maximal external rotation force (heels together). Then flex the knees to 90 and apply the same force.
+ve = excessive ER (>10*) compared to uninjured leg.
Test(s) for ITB Syndrome?
Noble’s Compression Test
Renne’s Test
Ober’s Test (Hip Aswell)
Test(s) for MCL Injury?
Varus Stress Test
Describe how you would carry out Thessaly’s Test and what a positive diagnoses indicates:
Meniscal Tears
Patient standing on affected leg (can hold onto examiner for balance). Patient slightly flexes on affected leg then rotates both ways.
+ve = pain, locking or catching
Test(s) for Meniscal Injury?
McMurray Test
Apleys Test
Ege’s Test
Thessaly’s Test
Test(s) for Osteochondritis Dessicans?
Wilson’s Test
Describe how you would carry out McMurray’s Test and what a positive diagnoses indicates:
Meniscal Tears
Patient supine, grasp knee joint line and sole of foot. Enter into maximal flexion, then extend the knee with either:
IR + Varus force (lateral meniscus)
ER + Valgus force (medial meniscus)
+ve = pain, snapping, locking or audible clicking
Test(s) for PFJ joint Disorder?
Clarke’s (A.K.A Patellar Grind)
Describe how you would carry out Lachman’s Test and what a positive diagnoses indicates:
ACL Injury
Patient supine with testing knee flexed 20-30°. Stabilize femur
anteriorly and pull tibia anteriorly.
+ve = excessive anterior translation with lack of end-feel.
Describe how you would carry out Wilson’s Test and what a positive diagnoses indicates:
Osteochondritis Dissecans
patient seated with legs over plinth, bend to 90* angle then grasp foot and bring tibia in internal rotation. Then instruct the patient to extend his leg.
+ve = Pain (expected at 30* flexion)
Describe how you would carry out Apleys Test and what a positive diagnoses indicates:
Meniscal Injuries
Patient lying prone with 90* flexion, place knee over patients hamstring. Then apply compression and rotation, then with distraction and rotation.
+ve = pain or excessive rotation.
Test(s) for MCL Injury?
Valgus Stress Test
Describe how you would carry out the Anterior Drawer Test and what a positive diagnoses indicates:
ACL Integrity.
Patient lies with bend in knee, PT sits on pateints foot. Pull lower leg towards you attempting to anteriorly displace tibia.
+ve = anterior displacement of tibia or lack of end feel.
Describe how you would carry out Varus Stress Test and what a positive diagnoses indicates:
LCL Integrity
Patient supine with knee in full extension. Apply a varus force to the tibia with a countering stabilisation of the femur.
+ve = laxity (potentially pain).
Describe how you would carry out Ely’s Test and what a positive diagnoses indicates:
Rec Fem Tightness / Spasticity
Patient prone, place hand on lower back and grasp heel then passively flex the knee quickly touching heel to buttock.
+ve = heel does not touch buttock or hip rises up from the table (or pain / tingling)
What is the Insall-Salvati Ratio?
The ratio used in measuring patellar height to detect alta & baja.
The length of the patellar tendon in relation to length of the patella bone using XR or MRI.
Test(s) for Rectus Femoris Spasticity or Tightness?
Ely’s Test
Test(s) for Effusion?
Patellar Tap Test
Fluid Displacement Test
Describe how you would carry out Valgus Stress Test and what a positive diagnoses indicates:
MCL Integrity
Patient supine with knee in full extension. Apply a valgus force to the tibia with a countering stabilisation of the femur.
Can be performed with 30* flexion to isolate the MCL further.
+ve = laxity (potentially pain).
Describe how you would carry out Fluid Displacement Test and what a positive diagnoses indicates:
Effusion.
Supine with knee extended, stroke upwards on the medial aspect of the knee then downwards on the lateral aspect.
+ve = fluid moving towards the medial aspect of knee on lateral stroke.
Describe how you would carry out Ege’s Test and what a positive diagnoses indicates:
Meniscal Injury
Patient standing, feet shoulder width then squat down with either:
Feet & knees pointing outwards, = Medial Meniscus
Feet & knees pointing inwards = Lateral Meniscus
+ve = pain and/or clicking
Describe how you would carry out Patellar Apprehension Test and what a positive diagnoses indicates:
Lateral Patellar Instability
Supine position with knee flexed to 30*. Relax the quadriceps to allow passive movement of the patella, using both thumbs press the medial aspect of the patella moving it laterally.
Modified = Moving Apprehension - get the patient to flex and extend with the medial pressure.
+ve = Pain and/or apprehension.
Describe how you would carry out Patellar Tap Test and what a positive diagnoses indicates:
Infrapatellar Effusion
Supine lying with knee extended, apply pressure proximally to patella then ‘tap’ on patella to push fluid around.
+ve = ‘floating’ patella (-ve would have patella already in contact with the femur.
