Anatomy of the Tibiofemoral joint
The distal site for the iliotibial band to attach
What is Gerdys Tubercle
Provides resistance against posterior translation of the tibia.
What is the posterior cruciate ligament?
During flexion the patella glides
What is inferiorly?
Rotation, hyperextension, valgus
What is an ACL injury?
+ apprehension test
What is a patella dislocation?
Actions include IR of the tibia and knee flexion
What are the semitendinous and membranosus
When the knee is flexed past 30 degrees I am a knee flexor
What is the iliotibial band?
In open kinetic chain forces across the patella are lowest
What is at 90 degrees of knee flexion?
Rotation and knee flexion
What is a meniscal injury?
Occurs as a result of rapid growth and increased quadriceps strength
What is osgood-schlatters disease?
Gracilis, semitendinosus and sartorius
What is the PES ANSERINE muscle group?
Provides stability against varus forces, external tibial rotation and anterior/posterior forces at the knee
What is the posterolateral corner?
Medial retinaculum, capsule and patellofemoral ligament
What are medial static restraints?
2/5 MMT Tibia internal rotation
pain on the lateral side of the knee
clicking, popping and anterior knee pain
What is the synovial plica?
Lateral head of the gastrocnemius, LCL, Iliotibial band, biceps femoris tendon, popliteus tendon
What is the posterior lateral corner of the knee?
Major stabilizing ligaments of the lateral mensicus
What are the ligaments of Wrisberg and Humphrey?
Vastus lateralis
What is lateral dynamic restraint?
+ compression extension test
What is infra patella fat pad contusion?
Caused by malalignment and faulty tracking of the patella
What is PFPS?
Completely envelops the bony surface of the knee
What is the joint capsule?
Assists the cruciate ligaments in controlling posterolateral rotary instability.
What is the arcuate ligament?
Camel sign
What is patella Alta?
Locking and clicking
Pain with joint compression
Crepitus near joint line and femoral condyle
What is chondral/osteochondral fracture
Palpable tenderness on the patella
Unable to flex the knee to 90 degree
Tenderness to palpation on the fibular head
What is the Ottawa knee rules?
