1. KNEE JOINT

2. Introduction

3. Bones Forming the joint Condyles of femur Condyles of tibia Articular surface of patella

4. Condyles of femur and tibia

5. Articular surface of Patella

6. Ligaments of Knee joints Capsular ligament with Synovial membrane Ligamentum Patellae Tibial collateral ligament Fibular collateral ligament Oblique popliteal ligament Arcuate ligament

7. Contd … Anterior cruciate ligament Posterior cruciate ligament Coronary ligament Medial menisci Lateral menisci Transverse ligament & menisco - femoral ligaments

8. Capsular ligament

9. Synovial membrane

10. Synovial reflection of knee joint

11. Ligamentum Patella

12. Tibial & Fibular Collateral Ligament

13. Oblique Popliteal Ligament

14. Arcuate Ligament

15. Anterior and Posterior Cruciate ligament

16. Functions of anterior cruciate ligament It binds the bone together It is stretched during extension and therfore prevents hyper-extension. It prevents forward displacement of femoral condyles .

17. Functions of posterior cruciate ligament It binds the bone of the joint It is streched during flexion and prevents backward displacement of tibial condyles . Both cruciate ligaments prevents side to side displacement of femur and tibia.

18. Coronary ligament

19. Transverse ligament

20. Mensico -femoral ligament

21. Medial & Lateral Mensicus

22. Functions of mensicus They increase the concavity of tibial condyles for better adaptation with femoral condyles They maintain a potential joint space for flushing of synovial fluid to provide nutrition to articular cartilage. It acts as a shock absorber to protect articular cartilage during weight transmission. It also helps in gliding and angular movements.

23. Contd … Pheripheral attached part of menisci is vascular and gets nutrition from the capsular arteries. Inner part of menisci is avascular and gets its nutrition from synovial fluid.
