1. The Knee Joint

2. The Knee Joint
Is the largest synovial joint
in the body

3. The Knee Joint
Found at the junction of
the thigh and the leg

4. The Knee Joint
Consists of 3 distinct articulations
to form a complex hinge joint

5. The Knee Joint
Consists of 3 distinct articulations
to form a complex hinge joint
•Medial Tibiofemoral joint

6. •Patellofemoral joint

22. Ligaments of the Knee Joint

23. The knee joint is
stablised on either side
by collateral ligaments
Medial view

24. Medial Collateral Ligament
Medial view
Arises from the
medial epicondyle of the Femur
Wide insertion onto the proximal
aspect of the medial Tibia

25. Medial Collateral Ligament
Medial view
Resists forces that push the
knee medially

26. Lateral Collateral Ligament
Lateral view
Arises from the
Lateral Epicondyle of the Femur
Cord-like structure that inserts anterior
to the Apex of the Fibular head

27. Lateral Collateral Ligament
Lateral view
Stabilises the lateral side of the knee

28. Cruciate Ligaments
Anterior view with the Knee Joint flexed

29. Anterior Cruciate Ligament
Arises from the anterior
aspect of the Intercondylar
area of the Tibia
Inserts onto the medial
aspect of the
Lateral Femoral Condyle

30. Anterior Cruciate Ligament
Stabilises the Knee by
preventing forward
movement of the Tibia
relative to the Femur

31. Posterior Cruciate Ligament
Posterior View

32. Posterior Cruciate Ligament
Posterior View
Attaches to the lateral aspect of
the Medial Femoral Condyle and
the Intercondylar Notch

33. Posterior Cruciate Ligament
Posterior View
Attaches to the lateral aspect of
the Medial Femoral Condyle and
the Intercondylar Notch
Distal part of the Ligament attaches to
the posterior aspect of the
intercondylar Region of the Tibia and
the adjacent posterior Tibia

34. Posterior Cruciate Ligament
Posterior View
Prevents backward
movement of the
Tibia relative to the Femur

35. Oblique Popliteal Ligament

36. Oblique Popliteal Ligament
Arises as an extension from the
lateral side of semimembranosus
tendon
Attaches to medial aspect of
Lateral Femoral Condyle

37. Oblique Popliteal Ligament
Blends with posterior joint capsule
Forms part of floor of the popliteal
fossa
Function: primary stabiliser of the
Posterolateral Knee

38. Arcuate Popliteal Ligament
Fibres blend with the joint capsule
and run from Lateral Femoral
Condyle and adjacent
intercondylar area of posterior
Tibia
to
Head of the Fibula

39. Arcuate Popliteal Ligament
Stabilises posterior aspect
of the Knee

40. Patellar Ligament
(Patellar Tendon)
Attaches the lower pole
of Patella to the Tibial
Tuberosity
It is the continuation of
the tendon of
Quadriceps Femoris

41. Patellar Ligament
(Patellar Tendon)
Attaches the
Patella to the Tibia
It is the continuation of
the tendon of
Quadriceps Femoris

42. Muscles and Tendons
around the Knee Joint

43. Sartorius
Gracilis
Semitendinosus
Means ‘Goose’s Foot’
Comprises 3 conjoined
tendons
Pes Anserinus
Medial view

44. Semimembranosus
Divides into a series of slips at the level of
the knee and has a complex attachment
Most fibres attach to the posterior aspect
of the Medial Tibial Condyle
Some fibres form a strong expansion and
pass obliquely upwards to the Lateral
Femoral Condyle to form the oblique
Popliteal Ligament
Posterior view

45. Biceps Femoris
The Long and Short Heads unite to
form a tendon that inserts onto the
head of the Fibula
Posterior view

46. Iliotibial
Tract
Attaches to
Gerdy’s Tubercle
on the anterior aspect of the
Lateral Tibial Condyle
Tensor Fasciae Latae
Gerdy’s Tubercle
Proximally it receives two muscles
•Tensor Fasciae Latae
•Gluteus Maximus
Iliotibial Tract

47. Quadriceps
Femoris
Patella
Patellar
Ligament
Quadriceps Femoris
comprises 4 muscles
•Rectus Femoris
•Vastus Lateralis
•Vastus Intermedius
•Vastus Medialis
Extends and stabilises
the knee during gait

situated one on each Tibial Facet

50. Menisci
Each Meniscus has an anterior and posterior horn through which
the Meniscus gains attachment to the tibial plateau

51. Menisci are wedge-shaped in
cross-section
The Menisci widen and deepen the
Tibial articular surface that
receives the Femoral Condyles
