What are cartilage of the knee
Medial and lateral meniscus
How examine knee
flexed position
What is suggestive of intro-articular pathology in the knee
pain after exercise and at end of day
better with rest
What is suggestive of patellar or patelofemoral problems in the knee
pain when going up stairs
pain when keeping the knee in a flexed position for long periods of time
What is suggestive of meniscal pathology of the knee
pain when knee is hyperflexed and twisting
clicking of popping of the knee with joint locking
What is suggestive of a tibial plateau fracture in the knee
pain with weight bearing
What is a possible concern with sense of instability in the knee
ligament disruption
What ligament protects against valgus forces on the knee
MCL
What ligament protects against varus forces on the knee
LCL
what ligament protects against anterior movement of the tibia on the knee
ACL
What ligament protects against posterior movement of the tibia on the knee
PCL
What do people talk about when ACL tears occurs in the knee
noncontact injury with “pop”
What will people that report a contact injury with “pop” of the knee have
MCL or LCL tear
meniscus tear
fracture
What will people that report acute swelling with the knee have
ACL tear PCL tear fracture knee dislocation patellar dislocation
What can sometimes be seen with quadriceps imbalance
J sign of the patella during extension
What are the tests for finding joint effusion
bulge sign
balloon sign
balloting the patella
What is lachman’s test
try to pull tibia anterior of knee
What is the anterior drawer test for the knee
flex knee
sit on foot
try to pull tibia anteriorly
What is the sag sign for the knee
flex hip and have lower leg at parallel to the table
see if tibia will move posteriorly
What are tests for meniscus evaluation of the knee
Apley’s grind test
Mcmurray’s test
What is mcmurray’s test for the knee
squeeze the MCL and LCL of the flexed knee
rotate heel and feel for locking or crepitus
