Presentation Transcript

  1. KNEE INJURIES • Review Gross and Functional Anatomy. • Discuss traumatic injuries to the knee. • Discuss overuse injuries in and about the knee.

  2. KNEE INJURIES • Discuss the signs and symptoms of the specific injuries. • Discuss causes and treatments.

  3. KNEE (Anterior view)

  4. BEHAVIORAL CHARACTERISTICS OF STRUCTURES AROUND THE KNEE

  5. ANTERIOR CRUCIATE LIGAMENT LOCATION

  6. POSTERIOR CRUCIATE LIGAMENT LOCATION

  7. STABILIZING ROLE OF THE ANTERIOR CRUCIATE LIGAMENT

  8. HEAT SENSITIVE VIEWS OF THE ANTERIOR CRUCIATE IN FLEXION

  9. STABILIZING ROLE OF THE POSTERIOR CRUCIATE LIGAMENT

  10. HEAT SENSITIVE VIEW OF THE POSTERIOR CRUCIATE IN FLEXION AND EXTENSION

  11. A.C.L. and P.C.L. LINKAGE

  12. MEDIAL COLLATERAL LIGAMENT DURING FLEXION AND EXTENSION

  13. LATERAL VIEW OF KNEE FLEXION and EXTENSION

  14. PATELLO-FEMORAL JOINT DURING FLEXION AND EXTENSION

  15. NORMAL KNEE MOTION KNEE FLEXION-EXTENSION takes place between the bottom of the femur and the top of the menisci. TWISTING MOTION takes place between the bottom of the menisci and the tibia.

  16. MENISCUS OF THE KNEE Purpose: Equalize weight distribution across the knee joint. Shock absorption.

  17. Coronary Ligament Medial is tighter than the lateral. Thus, there is less mobility medially.

  18. MENISCAL INJURY Medial Meniscus: excessive external rotation of the tibia. Lateral Meniscus: excessive flexion of the knee.

  19. MECHANISMS OF INJURY • VALGUS • VARUS • HYPEREXTENSION • HYPERFLEXION • INTERNAL ROTATION • EXTERNAL ROTATION

  20. X VALGUS Distal bone of the joint moves away from midline of the body.

  21. Medial Support Complex Not Shown: Quads Medial Head of Gastrocnemius Medial Hamstrings

  22. X VARUS Distal bone of the joint moves towards the midline of the body

  23. Lateral Support Complex Not Shown: Iliotibial Band Biceps Femoris M. Poplitius Tendon Head of the Gastrocnemius

  24. ANTERIOR CRUCIATE

  25. HYPEREXTENSION

  26. ANTERIOR CRUCIATE
