The Knee MOI
MOI- Osgood Schlatter Disease (3)
1) Apophysitis 2) Usually in growing teens 3) Tendon pulls on tubial tubercle
MOI- PCL Sprain (3)
1) Blow/fall to flexed knee (Car Crash-dashboard blow) 2) Hyper extension 3) Valgus blow
MOI- ITB-FS (2)
1) Friction over lateral femoral condyle 2) Usually associated with tightness of ITB *tightness causes FS
MOI- Bursitis (3)
1) Overuse- muscles tight and tend to ware and tear on bursa 2) Contact- pressure on the front of the knee/blow 3) A lot of kneeling *can be acute, chronic, or recurrent
MOI- ACL Sprain (4)
1) Rotation upon a fixed foot (cutting)- most common 2) Sudden deceleration 3) Hyperextension 4) Valgus blow (blow on opp side)
MOI- Patellar Tendon Rupture (2)
1) Severe contraction 2) Chronic tendonitis *Often results from long term tendonpathy
MOI- Chondromalacia Patella (2)
1) Softening and deterioration of articular cartilage under patella 2) Probably caused by poor patella tracking or sublux/disloc
Why do we need our meniscus? (3)
1) Stabilization 2) W/o it, bones will rub 3) Stress on ligaments
MOI- Meniscal Injury (4)
1) Usually rotation on planted foot 2) Forced knee flexion 3) Valgus force 4) Egg beater kick (water polo)
MOI- MCL Sprain (2)
1) Valgus stress/blow 2) External rotation of foot
ACL stands for-
Anterior Cruciate Ligament
LCL stands for
Lateral collateral ligament
MCL stands for
Medial collateral ligament
MOI- Patellar Tendinitis
Overuse of knee extensor mechanisms (quads, patella, tendon)- jumping, kicking, running
Function of MCL
Prevents knee from going into valgus
PCL function
Purpose is to prevent posterior shift of tibia (Not common)
ACL function
Purpose is to prevent rotation and anterior shift of tibia on femur
MOI- Patellar Sublux/Dislocation
Quads force patella laterally as foot is planted w/ thigh internally rotated and tibia externally rotated causing a knee valgus force
MOI- LCL
Varus stress (Foot has to be forward)
