RF of meniscus tear:
acute:
chronic:
acute- all WB sports
Chronic/Degenerative:
greater the age, especially > 60 yrs. of age
male > female
worked related kneeling/squatting/stair climbing
Meniscus: structures involved :
attachment:
nearly circular wedged-shaped fibrocartilage discs on the tibial plateau
attached to the tibia via horizontal coronary ligaments
Meniscus Functions:
–outer
–inner
stability>shock absorption
deepen the joint surface for stability
–Outer 1/3
80% type I collagen
<1% of other types
–Inner 1/3
60% type II collagen
40% type I collagen
Medial meniscus characteristics: (3)
more “O” shaped
torn more frequently
attachment to MCL
Lateral meniscus characteristics: (2)
more “C” shaped
greater mobility without ligamentous attachment
There are various portions of the meniscus that can tear. T or F?
True

-Onset?
-ROM/WB?
Joint P! with possible referral into shin
Onset: if acute, trauma reported likely with WB sport
if chronic, gradual and unknown, typically in. an older individual w/o a prior injury
limited and P!ful motion
WBing limitation with possible catching or locking
Signs of Meniscal Injury:
Observation:
possible swelling
potential asymmetrical and antalgic gait
Signs of Meniscal Injury:
-ROM:
-Resisted Testing:
-Stress Tests:
limited and P!ful motions
potentially weak and P!full (severity dependent)
possibly P!full w/compression
