|
What are the 3 joints of the knee?
|
patellar - femur
medial femoral condyle - medial tibial condyle lateral femoral condyle - lateral tibial condyle |
|
|
Which 4 muscles attach to the superior edge of the patella? (list them going from lateral to medial)
|
Vastus lateralis (from femur)
Rectus femoris (from illim) Vastus intermedialis (from ant. femur) Vastus medialis (from med. of femur) |
|
|
Knee flexion involves both rolling and sliding. Which side (med or lat) sweeps through a greater arc?
|
The medial side is more securely anchored, so when the knee is flexed, the lateral side has a greater arc of rotation
|
|
|
Of the cruciate ligaments which is most likely to be injured?
|
The anterior, because the posterior is twice as strong
|
|
|
From their attachments on the tibia, which direction (med or lat) are the cruciate ligaments heading?
|
Anterior goes laterally
posterior goes medially |
|
|
When do the meniscus of the knee move, and in what direction? How could they get damaged?
|
When the knee is flexed they normally move posteriorly. If the ACL has been torn though, the tibia will slide too far foward and the femur will compress the meniscus between itself and tibia
|
|
|
These ligaments are thickenings of the knee joint capsule... Which is the most commonly injured?
|
The tibial and fibular collateral ligaments. The medial (tibial) b/c force usually comes form lateral side
|
|
|
Which ligament is joined to a meniscus?
|
the medial (tibial) collateral ligament is joined to the medial meniscus
|
|
|
What is the O'donoghue triad?
|
- cruciate
- meniscus - collateral If you find a tear in one of these there is nearly always a problem in the other two structures :( |
|
|
The illiofemoral, pubofemoral and ischiofemoral ligaments are tensed by what movements?
|
Illiofemoral - resists hyperextension (prevents femur from moving past vertical position)
pubofemoral - limits aBduction ischiofemoral - resists medial rotation |
