knee orthos Flashcards
patella ballottement
positive: floating sensation of the patella indicating a large amount of swelling in knee
fouchet’s sign
audible or palpable grinding or pain at the margin of the patella indicates patellar tracking disorder, peripatellar syndrome, or patellofemoral dysfunction
patella grinding test (second part of fouchet’s)
pain under patella indicates chondromalacia patella, pain over patella indicates prepatellar bursitis
clarke’s sign
pain in patella and/or failure to hold contraction indicates chonroamalacia patella
patella apprehension test
patient sensing that the patella is going to dislocate with a look of apprehension, pain or to prevent it they will contract their quad. indicates an unstable patella possibly a shallow trochlear groove
drawer test of the knee
increased P-A movement compared to normal knee is indicative of a partial or complete anterior cruciate ligament tear. increased A-P is a posterior cruciate ligment tear
normal motion is 6mm
slocum’s
excessive tibial movement and/or a soft end feel indicates torn ACL, posterolateral capsule, fibular collateral ligament, IT band
lachman’s
anterior movement of tibia indicates a tear of the anterior cruciate ligament and posterior oblique ligament
McMurray
a palpable or audible click/snap indicates a torn meniscus. the more the knee is flexed when the pop is felt, the more posterior the tear is
wilson’s
if knee locks or is painful around 30 degrees, then externally rotate.
pain disappears when the tibia is externally rotated indicates a possible osteochondritis dissecans of the knee
steinmann’s
if the pain moves posterior on flexion and anterior on extension, then it is a sign of a meniscal tear. if pain remains in one place consider coronary ligaments damage
knee adduction (varus) and abduction (valgus) stress test
lateral knee pain or increase in movement during varus stress indicative of a torn lateral collateral ligament
medial knee pain or increase in movement during valgus stress indicative of a torn medial collateral ligament
bounce home
knee does not fully extend or a rubbery end feel is felt when the knee extends or causes severe pain indicates meniscus tear
apley’s compression test
pain or crepitus on either side of the knee indicates meniscus injury on that side
apley’s distraction test
pain indicates nonspecific ligaments injury or instability of the medial and lateral collateral ligaments
