Leg Flashcards
Receives weight of the body from the femur
Tibia (medial)
Fibula (lateral, stick-like)
Contributes to the knee joint together with femur
Tibia (Fibula does not)
Largest and most complex joint. Acts as a hinge joint: flexion and extension.
Knee joint
Knee joint is structurally considered as…
Compound and bicondyloid
Connects the tibia and fibula
Interosseous membrane
Contributes to ‘locking’ of knee when standing
Rotation of femur to tibia (by knee joint)
3 joints surrounded by a single joint cavity
Patellofemoral
Lateral tibiofemoral
Medial tibiofemoral
What are the structures covered by the capsule of the knee joint?
- posterior and lateral aspects of the knee
- tibial and femoral condyles
What covers the capsule of the knee joint posteriorly?
2 heads of gastrocnemius (inserts to achilles tendon)
What structure enters the capsule and attaches to the lateral condyle of femur and lateral meniscus?
Tendon of popliteus
Capsule covers the anterior aspect of the knee. True or False?
False (It is covered by 3 ligaments: lateral patellar retinaculum, medial patellar retinaculum, patellar) cannot see their separation
What are the EXTRACAPSULAR LIGAMENTS of the knee joint?
FOAT
Tibial collateral ligament
Fibular collateral ligament
Oblique popliteal ligament
Arcuate popliteal ligament
What are the INTRACAPSULAR LIGAMENTS of the knee joint? (A-P)
Anterior cruciate ligament
Posterior cruciate ligament
Ligament: stout, flat band, part of the capsule. Large superficial part and smaller deep part.
Tibial (medial) collateral ligament
Prevents the knee from buckling INWARD
Tibial collateral ligament
OUTWARD - Fibular collateral ligament
Tendons that pass through Tibial collateral ligament. Collectively known as ‘pes anserinus’
Sartorius (superior)
Gracilis
Semitendinosus
Ligament: Round, cord-like structure, separated from the capsule of knee joint
Fibular (lateral) collateral ligament
Fibular or lateral collateral ligament is surrounded by what tendon?
Tendon of biceps femoris
Whatchu call the muscle that stabilizes the thigh?
Tensor fasciae latae
It is tensed by the tensor fasciae latae
Iliotibial tract (together with tendon of biceps femoris - Lateral aspect of knee joint)
