Knee Flashcards
Vastus lateralis
Proximal: greater trochanter and lateral lip of Linea aspera
Distal: via common tendinitis (quadriceps tendon) and independent attachment to base of patella; indirectly via patellar ligament to tibial tuberosity; vastus medialis and lateralis also attach to tibia and patella via aponeurosis
Nerve: femoral
Rectus femoris
Proximal: AIIS and ilium superior to acetabulum
Distal: via common tendinitis (quadriceps tendon) and independent attachment to base of patella; indirectly via patellar ligament to tibial tuberosity; vastus medialis and lateralis also attach to tibia and patella via aponeurosis
Nerve: femoral
Vastus medialis
Proximal: intertrochanteric line and medial lip of Linea aspera
Distal: via common tendinitis (quadriceps tendon) and independent attachment to base of patella; indirectly via patellar ligament to tibial tuberosity; vastus medialis and lateralis also attach to tibia and patella via aponeurosis
Nerve: femoral
Vastus intermedius
Proximal: anterior and lateral surfaces of shaft of femur
Distal: via common tendinitis (quadriceps tendon) and independent attachment to base of patella; indirectly via patellar ligament to tibial tuberosity; vastus medialis and lateralis also attach to tibia and patella via aponeurosis
Nerve: femoral
Semitendinous
Proximal: ischial tuberosity
Distal: medial surface of superior part of tibia
Nerve: tibial division of sciatic nerve
Semimembranosus
Proximal: ischial tuberosity
Distal:posterior part of medial condyle of tibia; reflected attachment forms oblique popliteal ligament
Nerve: tibial division of sciatic nerve
Biceps femoris long and short heads
Proximal:
Long- ischial tuberosity
Short- Linea aspera and lateral supracondylar line of femur
Distal: lateral side of head of fibula; tendon is split at this site by fibular collateral ligament of knee
Gastrocnemius
Proximal:
Lateral-lateral aspect of lateral condyle of femur
Medial- popliteal surface of femur, superior to medial condyle.
Distal: posterior surface of calcaneus via calcaneus tendon
Nerve: tibial
