Knee, Tibia, and Fibula Structures

which condyle of the femur is larger

medial femoral condyle

function of the larger medial condyle

allows proper knee alignment and locking-home mechanism

intercondylar eminence

anterior cruciate ligament

ACL origin

medial surface of lateral femoral condyle

ACL insertion

anterior surface of intercondylar eminence

posterior cruciate ligament

PCL origin

Lateral surface of medial femoral condyle

PCL insertion

Posterior to the intercondylar eminence

ACL/PCL function

resist tibial/femoral translation, aid in resisting rotation of tibia/femur

medial collateral ligament

lateral collateral ligament

MCL/LCL function

resists valgus/varus forces, aid in limiting rotation of femur/tibia

medial meniscus

lateral meniscus

coronary ligament knee

attaches medial meniscus to MCL

components of anterior joint capsule of the knee

IT band, patella, patellar ligament, lateral patellar retinaculum, medial patellar retinaculum

lateral patellar retinaculum

continuation of vastus lateralis

medial patellar retinaculum

continuation of vastus medialis

components of posterior joint capsule of the knee

oblique popliteal ligament and arcuate popliteal ligament

oblique popliteal ligament

arcuate popliteal ligament

false bursa

communicate with knee joint synovial fluid

false bursa of the knee

suprapatellar and deep infrapatellar

suprapatellar bursa

deep infrapatellar bursa

true bursa

separate from knee synovial fluid

true bursa of the knee

prepatellar and superficial infrapatellar

prepatellar bursa

superficial infrapatellar bursa

pes anserine bursa

gastrocnemius bursa (Baker's cyst)

medial tibial condyle

lateral tibial condyle

tibial plateau
