Knee Pain Wk 2 Flashcards
Bony palpation of knee
patella
medial tibial plateau (ext rotation tibia)
tibial tubercle
medial femoral condyle (flex knee)
lateral tibial plateau (int rotation of tibia)
lateral femoral condyle (flex knee)
fibula head (dorsi/plantar flex)
soft tissue palpation of knee
quadriceps (as unit and individual) vastus lateralis vastus medialis vastus intermedius rectus femoris infrapatellar tendon bursae prepatellar superficial infrapatellar medial meniscus lateral meniscus pes anserine area (3 tendons come together) sartorius gracilis semitendinosus popliteal fossa lateral collateral ligament medial collateral ligament gastrocnemius
Knee range of motion
flexion 135
extension 0
internal and external rotation
McMurray Sign
supine, flex hip to 90, knee to 90. hold heel apply external rotation. place hand on lateral knee and apply valgus stress. maintain these while extending knee
positive: clicking sound or pain by knee joint
indicates:
- tear of medial meniscus is positive on external rotation
- tear of lateral meniscus if positive on internal rotation
Medial Collateral Ligament tests & AKAs
aka Abduction stress test, valgus stress test
supine, stabilze lateral thigh, grasp above medial ankle and apply abduction of knee pressure
positive: gapping and/or elicited pain above/at/below joint line
indicates: torn medial collateral ligament
Lateral collateral ligament test and AKAs
aka Adduction stress test, Varus stress test
supine, stabilze medial thigh, grasp lateral ankle and push medial to open lateral side of joint
positive: gapping and/or elicited pain above/at/below the joint line
indicates: torn lateral collateral ligament
bounce home test
supine, flex knee and grasp heel and posterior knee. glently pull knee into extension
positive: knee does not go into extension, slight flexion remains
indicates: diffuse swelling of the knee, accumulation of fluid, due to possible torn meniscus
Drawer Test
supine, knee bent. sit on patients foot. pull tibia toward you, then push away
- gapping greater than 6mm, tibia moves anterior, when the leg is pulled indicates torn anterior cruciate ligament
- gapping greater than 6mm, tibia moves posterior, when the leg is pushed indicates tear of posterior cruciate ligament
Lachman test
supine, knee flexed to 30. grasp proximal tibia and distal femur. attempt to pull tibia forward to feel joint play
-gapping with the tibia moving away from femur indicates anterior cruciate ligament or posterior oblique ligament instability
Apprehension test of patella
supine, push patella laterally while looking at patients FACE!
positive: apprehension, distressed facial expression, or contraction of the quadriceps to bring patella back in line
indicates: chronic patella dislocation, or predisposition to dislocation
patella femoral grinding test
aka Clarke sign
supine, use web on hand to trap patella against femur. ask pt to contract quadriceps for while holding for a few seconds
- retropatellar pain and the patient is unable to hold the quadriceps contraction
- degenerative changes of the patellar facets and/or within the trochlear groove (chondromalacia patella)
Patella Ballottment test
pt supine, knee extended. A-P pressure on medial patella
- a floating sensation of the patella
- a large amount of swelling in knee
Apley Compression test
pt prone, flex knee to 90. stabilize thigh with your knee. downward pressure on patients heel while internally and externally rotating
- patient points to side of pain
- pain on medial side is medial meniscus tear, pain on the lateral side is lateral meniscus tear
Apley Distraction Test
prone, knee at 90. stabilze thigh with your knee. grab ankle just below malleolus. pull up, then pull up while internally and externally rotating.
- patient will point to side of pain
- pain on medial side indicates medial collateral ligament tear. pain on the lateral side indicates lateral collateral ligament tear
Heart exam where to palpate for pulsations and thrills
pulsations=finger pads
Aortic
Pulmonic
Erb’s point
tricuspid
mitral(apical impulse for location and amplitude)
epigastic (flat hand toward left shoudler)
-pulsations coming superior to inferior may indicate right ventricular enlargement
-pulsations coming inferior to superior, or P-A may indicate abdominal aortic aneurysm
Thrills=ball of hand
turbulent blood flow causing vibrations
aortic pulmonic erb's point tricuspid mitral (knife edge)
