KNEE Flashcards
Two distinct articulations
Tibiofemoral
Patellofemoral
> 185 = GENU VALGUM =
KNOCK KNEES
<175 = GENU VARUM =
BOW LEGS
Which meniscus
- Anterior horn connects to ACL
- Posterior Horn connects to PCL
MEDIAL Menisucus
Which ligament
restricts valgus stress and lateral rotation
most critical role with knees flexed
MCL
Valgus test for
Varus Test for
VALGUS – MCL
VARUS – LCL
superficial fibrous layer w thin inner synovial membrane
Fxn: Encloses tibiofemoral & patellofemoral joints
Joint Capsule
separates deep infrapatellar from synovial cavity
Hoffa’s fat pad:
restricts VALGUS stress w knee flexed 20-30*,
also restricts lateral rotation, intracapsular ligament, great healing
capacity b/c rich blood supply
MCL
restricts VARUS stress w knee flexed 20-30
LCL
Anteromedial band stressed in knee flexion - Anterior drawer tests AM band - positive is >6mm w soft end feel
Posterolateral bands stressed in knee extension
- Lachman’s tests PL band
3 tendons conjoin to attach at pes anserinus tendon (on anteromedial tibia) - Semitendinosus, sartorius & gracilis
Goose’s foot
Most common pattern of knee pain
Medial Knee Pain
Fibular Head can have what type of dysfunctions
Anterior and Posterior
The tibia can have what type of dysfunctions
IR and ER
effusion or bleeding into the knee - occurs after acute knee trauma
HEMARTHROSIS
MCC d/t ACL tear
Lat knee snapping along femoral condyle is due to
ITBS
pain an inch or so BELOW medial joint line
Pes Anserine bursitis
A/w OA, gout, trauma
jumpers knee =
patellar tendonitis
focal pain at the inferior pole of the patella
focal pain at the tibial tubercle in pt under 19 y/o
osgood Schlatters disease
MC location of knee pain =
MEDIAL
MC injured ligament =
MCL
MC Inflammed bursa =
ANSERINE
