  1. KNEE JOINT KNEE JOINT INTRODUCTION TYPE OF JOINT BONES ARTICULATING LIGAMENTS RELATIONS MOVEMENTS & MUSCLES BLOOD SUPPLY NERVE SUPPLY APPLIED ANATOMY

  2. TYPE OF JOINTBONES ARTICULATING • CONDYLAR/ MODIFIED HINGE JOINT. • BONES-LOWER END OF FEMUR,UPPER END OF TIBIA & PATELLA.

  3. ARTICULATING SURFACES • FEMORAL SURFACE • TIBIAL SURFACE • PATELLAR SURFACE

  4. LIGAMENTS • FIBROUS CAPSULE • COLLATERAL LIGAMENTS- TIBAL &FIBULAR. • CRUCIATE LIGAMENTS-ANTERIOR &POSTERIOR. • MENISCI- MEDIAL & LATERAL. • MENISCO FEMORAL LIGAMENT • OBLIQUE POPLITEAL LIGAMENT • TRANSVERSE LIGAMENT • CORONARY LIGAMENTS • ARCUATE LIGAMENT

  5. LIGAMENTS

  6. LIGAMENTS

  7. SYNOVIAL MEMBRANE,BURSAE & RELATIONS • SM-LINING, EXTENSIONS. • BURSAE- ANTERIOR,POSTERIOR,MEDIAL & LATERAL. • ANTERIOR –SUPRAPATELLAR (ARTICULARIS GENU), PREPATELLAR, SUPRAPATELLAR – SUPRFICIAL & DEEP. • POSTERIOR – SM BURSA. • MEDIAL – BURSA ANSERINUS • LATERAL – POPLITEAL.

  8. MOVEMENTS • FLEXION-GLIDING & SPINNING. • EXTENSION- GLIDING & SPINNING. • ROTATION-COJUNCT (20*- 30*) & ADJUNCT(50*- 70*)./ MEDIAL & LATERAL. • LOCKING & UNLOCKING

  9. MUSCLES • FLECTION – HAMSTRINGS, SARTORIUS, GRACILIS, G’CNEMIUS. • EXTENSION – (190*) QUADRICEPS. • MEDIAL ROTATION – SM,ST,Gracilis,Sartorius, Popliteus. • LATERAL ROTATION – Biceps Femoris. • UNLOCKING – POPLITEUS.

  10. BLOOD SUPPLY • Popliteal Artery- 5 genicular branches • Femoral Artery- 1br. • Lateral Circumflex Femoral Aa- 1br. • Anterior Tibial- 1recurrent br. • Posterior Tibial-1 circumflex Fibular br.

  11. NERVE SUPPLY • Femoral nerve- from nerve to 3 vasti. • Tibial nerve- superior & inferiorgenicular Nerve. • Common Peroneal Nerve- lateral(superior& inferior) genicular nerves,recurrent geniicular Nerve. • Posterior Division of Obturator nerve.

  12. APPLIED ANATOMY • INJURY TO COLLATERAL LIGAMENTS. • RUPTURE OF CRUCIATE LIGAMENTS.(ANTERIOR & POSTERIOR DRAWER TEST) • MEDIAL MENISCUS- BUCKET HANDLE TEAR. • LATERAL MENISCAL TEAR. • PREPATELLAR BURSITIS. • INFRAPATELLAR BURSITIS. • POPLITEAL BURSITIS (BAKER’S CYST) • # PATELLA. • DISLOCATION OF PATELLA- Q ANGLE (15*)- IN FEMALES. • GENU VARUM - BOW KNEE. • GENU VALGUM – KNOCK KNEE. • GENU RECURVATUM. • JOINT EFFUSION. • HAEMARTHROSES. • OSTEO ARTHRITIS. • ARTHROSCOPY.
