Knee Flashcards
Bounce home test
Positive: knee does not go into full extension [Slight flexion remains]
Lateral collateral ligament test a.k.a. stress test a.k.a. varus stress test
Positive: gapping and or elicited pain above at or below joint line
Indicates: torn lateral collateral ligament
Drawer test
Positive:
- Gapping > 6 mm [tibia moves posterior] when the leg is pushed
- Gapping > 6mm [Tibia moves anterior] when the leg is pulled
Indicates:
- Torn posterior cruciate ligament
- Torn anterior cruciate ligament
Lachman Test
Positive: gapping with the tibia moving away from the femur
Indicates: anterior cruciate ligament or posterior oblique ligament instability
Apprehension test for the patella
Positive: apprehension, distress of facial expression, contraction of quadriceps to bring patella back in line
Indicates: chronic patella dislocation or predisposition to dislocation
Patella femoral grinding test [a.k.a. Clark sign]
Positive: retropatellar pain and the patient is unable to hold the quadriceps contraction
Indicates: degenerative changes of the patellar facet and or within the trochlear groove (Chondromalacia patella)
Patella Ballottment Test
Positive: a floating sensation of the patella
Indicates: a large amount of swelling in the knee
Apley Compression Test
Positive: patient points to side of pain
Indicates: pain on medial side is medial meniscus tear. Pain on the lateral side indicates lateral meniscus tear
Apley Distraction Test
Positive: patient will point to side of pain
Indicates: pain on the medial side indicates medial collateral ligament tear. Pain on the lateral side indicates lateral collateral ligament tear
ROM
Flexion = 135°
Extension = 0
Internal rotation
External rotation
McMurray sign
Positive: clicking sound or pain by knee joint
Indicates:
Tear of the medial meniscus is positive on external rotation
Tear of lateral meniscus is positive on internal rotation
The higher the leg is raised during extension when positive is elicited, the more posterior the meniscal injury
Medial collateral ligament test a.k.a. abduction stress test a.k.a. Valgus stress test
Positive: gapping and or elicited pain above or below joint line
Indicates: torn medial collateral ligament
