Test 2.5 Flashcards
whats the characteristic of a transverse meniscal tear
- mid-substance tear
- associated with traumatic rotation
- leads to further tears
whats the characteristics of a flap tear
- extends from the middle of the meniscus to mid-substance
- more common in lateral meniscus
what the characteristic of a torn horn tear
- often breaks periphery of meniscus
- usually in posterior horn
- tear flaps in joint
whats the characteristics of a bucket-handle tear
-longitudinal tear from one horn to the other
where does a meniscal tear usually occur
posterior horn
which heals faster the outer 1/3 or inner 2/3
outer 1/3
whats the MOI of a meniscal tear
- may be due to MCL sprain
- cutting motion with plated leg externally rotated
what the signs and symptoms for a meniscal tear
- “locking” at the knee preventing extension
- crepitus with AROM
- joint-line tenderness
- slow onset of effusion
whats the special test for a meniscal tear
- McMurrays
- Apleys compression and distraction
- Thessalys
what does the unhappy or unholy tri-ad consist of
ACL, MCL, medial menicus lesion
which of the following is not a good test
1) McMurray
2) Apley’s compressive and distraction
3) Thessalys
McMurrays
how is the McMurrays test performed
patient supine, stand on lateral side, passive flex hip and knee at 90 degrees, use thumb and index finger, IR tibia and add valgus force which loads lateral menicus. Then do Varus load, which loads medial menicus. Watch for crepitus
how is Apleys Compressive and Distraction test performed
Patient prone, knee at 90 degrees, compress around distal shank and twist. Positive test results in pain.
Distraction test is the same thing without the twist but pull upward
how is Thessalys test performed
patient standing, bend knee at 30 degrees and stand on one leg and hold patients hand while they twist. Positive test results in pain.
For the Thessalys test does IR stress medial or lateral menicus and does ER stress medial or lateral
IR= medial menicus
ER=lateral menicus
