Knee joint

  1. 1. KNEE JOINTPrepared by :- Frencess- SalSazlina- Nurul Hidayah- Siti Suhaida
  2. 2. Intro The largest synovial joint of the body. Composed of 3 bones : - femur - tibia - patella 2 articulations : - tibiofemoral - patellofemoral
  3. 3. Tibio femoral joint Between the distal end of the femur and the proximal end of the tibia
  4. 4. Patella femoral joint Between the posterior aspect of the patella and the anterior intercondylar surface of the femur
  5. 5. Type It is a compound synovial joint Tibiofemoral – synovial hinge types of joint Patellofemoral – synovial plane types of joint
  6. 6. Q angle It is an angle formed by two intersecting lines : - anterior superior illiac spine ( ASIS )  mid patella - tibial tubercle  mid patella 10° - 15° in male 10° - 19° in female Increase of the angle causes the Genu Valgum ( knock knee ) Decrease of the angle causes the Genu
  7. 7. Q Angle
  8. 8. Capsule It is attached to the margins of the articular surfaces and covering the joint. Covering the joints and contains a lubricating fluid,called the synovial fluid.
  9. 9. Meniscus C- shaped sheets of fibrocartilage. The superior surface is in contact with the femoral condyles. Inferior surface is in contact with the tibial condyles. Serves as cushion to the bones & increase the stability of the joint. Prevent the bones to rub at each other while doing activities and producing a cracking sound Rubbing of the bones could lead to Osteoarthritis and other joint disease.
  10. 10. Ligaments Ligamentum patellae Lateral collateral ligament ( LCL ) Medial collateral ligament ( MCL ) Oblique popliteal ligament Cruciate ligament Anterior cruciate ligament ( ACL ) Posterior cruciate ligament ( PCL ) Transverse ligament
  11. 11. Muscles producingmovements Flexion – Hamstring ( semimembranosus, semitendinosus, rectus femoris ) Extension – Quadriceps ( vastus medialis , vastus lateralis, vastus intermedius, rectus femoris )
  12. 12. Blood supply Popliteal artery Femoral artery Tibial artery
  13. 13. Nerve supply Femoral nerve Sciatic nerve Obturator nerve
