The Knee Flashcards
What are the extracapsular ligaments of the knee
Tibial and fibular collateral ligaments
Acrucate and oblique ligament
Patellar ligament
What are the intracapsular ligaments
Cruciate ligaments
Menisici
What is the function of the Tibial collateral ligament
Stops the anterior-medial rotation of the knee
What is the function of the fibular collateral ligaments
Stops the posterior-Medial rotation of the knee
What does the oblique ligament do
Stops hyperextension and lateral rotation
What does the anterior cruciate ligament do
Stops the posterior rolling of the FEMUR
If damaged the tibia would look more anterior
What does the posterior cruciate ligament do
Stops the anterior rolling of the femur
If damaged, the tibia would look more posterior to the femur
What are the nerves of the posterior leg
The tibial nerve (would be in the popliteal fossa)
What are the structures of the popliteal fossa
The tibial nerve (most superficial)
Popliteal vein
Popliteal artery (most deep)
What is the function of the menisici
Shock absorber and would stabilise the joint
What is the function of the bursa and what can go wrong
Fluid filled sacks that would stop the friction of the knee joints
If they become inflamed they can swell
What are the types of bursa on the knee
Prepatellar bursa
Subcutaneous infrapatellar bursa
Deep infrapatellar bursa
Bursa under the head of the gastrocnemius
What are the artery’s that are part of the anastomoses in the anterior knee
The superior genicular artery’s
The inferior genicular artery s
The middle genicular artery (more on the posterior)
What is the purpose of knee locking
So that you can stand for long periods of time
What needs to happen for the knee to lock
The tibia needs to Medially rotate
The popliteus muscle needs to relax
