Perform the special test for the Menisci that can be performed prone
Apley's Compression and Distraction
Which meniscus is prone to acute trauma due to the shape and location?
Medial; more wider posterior than anterior- C-shaped
More isolated pain on the medial side
MCL
No MOI but reports clicking on anterior knee
avascular menisci, menisci in general, PF
Fall on a bent knee
PCL
Lever/Lilli's Test
ACL
Ottawa Knee Rules is great to rule in or rule out fracture?
sensitivity; 98.5%
specificity:48.6%
