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
