  1. Chapter 7 Knee Patella

  2. Knee Joint • Distal Femur • Proximal Tibia • Patella

  3. Patella • Anterior _______________ • Superior to ______________ • Flat Triangular bone

  4. Patella • ________________ – Inferior border • ______________ – Superior border

  5. Knee JointLigaments • _____________________________ • Fibular Collateral Ligament • ____________________________ • Tibial Collateral Ligament _____________________________ –Patella to Tibialtuberosity

  6. Knee JointLigaments • ___________________________ – Femur to Posterior Tibia • ___________________________ – Femur to Anterior Tibia

  7. Joint CapsuleBursa • ______________ Filled • Suprapatellar Bursa • ______________ Bursa

  8. Menisci • ____________________________ • Medial • Lateral

  9. Knee Imaging Routine • AP • Lateral • Internal Oblique • External Oblique • Tunnel • 65 kVp

  10. AP Knee • Pt Supine • Rotate ______________to align epicondyles parallel to table • Center _______________to apex of patella • Collimate to skin • Might need _________________

  11. Lateral Knee • Position for mediolateral projection • Flex ________________ • Epicondyles should be _____________ to table • ______________angle • Center mid knee • Collimate to knee

  12. Medial (Internal) Oblique • Position as AP • Rotate leg _______________ • Center _____________to apex of patella • Shows • Lateral _____________ in profile • Proximal_________________joint

  13. Lateral (External) Oblique • Position as AP • Rotate leg ____________ • Center ____________to patella • Shows • Medial ____________ in profile

  14. Tunnel View • Many ways to position. • Prone • Flex knee ________________ • CR perpendicular to _______________ • Supine • Flex knee ______________ • Raise cassette as close to the knee as possible • CR _______________________________to patella apex

  15. Patella Imaging Routine • PA • Lateral • Axial (Sunrise) • 40” SID • 60 kVp

  16. PA Patella • Pt Prone • Rotate leg _____________ • Center mid Patella • Collimate to skin

  17. Lateral Patella • Position as per Lateral Knee • Flex knee ____________ • CR to _________________ joint • Collimate down to patella

  18. Axial Patella(Sunrise) • If Prone Flex ________________ • Angle tube ____________________ • Center at petellofemoral joint • Collimate to patella • __________________ other ways to get it

  19. Axial Patella(Sunrise) • If Supine • Flex _________________ • Have pt _________________________ • Angle tube ___________________ to be perpendicular to IR • Collimate to patella
