13 Cards in this Set
- Front
- Back
|
Supine with knee flex
>5 mm movement (low leg—on “pulling”/anterior) = injury (typically ant cruciate lig) Excessive movement (low leg—on “pushing”/posterior) = injury (typically post cruciate lig) |
Anterior/posterior drawer sign
|
|
|
Pt prone, knee flex, compress—internally/externally rotate
Pain on either side indicates meniscus injury |
Apley’s compression test
|
|
|
Prone, knee flex 90, thigh stabilized, pull on ankle with internal/external rotation
Pain indicates nonspecific lig injury or instability (collateral ligs) |
Apley’s distraction test
|
|
|
(for patellar dislocation)
Supine, legs extended, displace patella laterally Apprehension on patient or contraction of quad mm indicates tendency to patella dislocation |
Apprehension test
|
|
|
Supine with knee flexed—pt relaxes/drops knee
Inability to fully extend or “rubbery” feel on full extension = + sign |
Bounce home test
|
|
|
(major knee joint effusion)
Press down above patella (+ = patella with elevate), then with other hand push patella “down” to femur (palpable tap of patella against femur = + sign) |
Ballotable patella test
|
|
|
(minor knee joint effusion)
|
Bulge test
|
|
|
Supine with knee flex to ~30 degrees
Thigh stable “pull” ant on low leg Excess movement = typically ant cruciate lig tear More reliable to assess cruciate than drawer sign (<meniscal impinge and less hamstring tension) |
Lachman’s test
|
|
|
(prone, knee flex 30, low leg moved post)
Posterior cruciate tear if excess movement |
Reverse Lachman’s
|
|
|
Supine with knee flexed, internal/external rotation with extension
Palpable/audible click indicates meniscus injury |
McMurray’s test
|
|
|
Supine, legs extended, move patella lat/med with downward pressure
Pain under patella indicative of chondromalacia patellae Pain over patella indicative of prepatellar bursitis |
Patella femoral grinding test
|
|
|
Collateral ligs
With some knee flexion also involves cruciate ligs |
Valgus (abduction) / Varus (adduction) stress tests
|
|
|
Same as McMurray's:
Supine with knee flexed, internal/external rotation with extension Palpable/audible click indicates meniscus injury |
Reduction click
|
