|
Definition
|
|
Term

|
|

|
Definition
| attaches to medial aspect of medial femoral condyle then comes down and crosses the knee. |
|
|

|
Definition
|
|
Term
| what is the purpose of the pes anserinus |
|
Definition
| provides medial joint stability |
|
|
Term
| what is the path of the fibular nerve at the knee |
|
Definition
| comes out from behind, wraps around lateral aspect of fibular head |
|
|
Term
| why does the medial meniscus get injured more than lateral meniscus |
|
Definition
| medial meniscus is connected to tendons, which keep it from moving as much |
|
|
Term
| what are the loadbearing surfaces of the patella |
|
Definition
| medial/lateral walls of the femoral condyle |
|
|
Term
| is the lateral or femoral wall of the femoral condyle longer |
|
Definition
| lateral wall of the femoral condyle is higher than the medial wall |
|
|
Term
| does the patellar loadbearing joint space ever touch the tibia |
|
Definition
|
|
Term
| does the medial or lateral femoral condyle have a larger surface area of the tibiofemoral joint |
|
Definition
|
|
Term
| how is the femoral head angled in respect to the femur |
|
Definition
|
|
Term
| why must the femoral head be anterior to the femur |
|
Definition
| to fit in the anterior facing acetabulum |
|
|
Term
|
Definition
| angle of the femoral head anterior to the femr |
