30. Anatomy?

31. Patella Fibular head Med & lat epicondyles Med & lat condyles Med & lat tibial plateaus

32. Pathology?

33. Varus knees with mild medial compartment degenerative arthritis. Patient has had a valgus producing osteotomy on R to relieve pressure on medial compartment Normal is 5-10 degrees valgus alignment between the fermoral and tibial shafts. Is 0 degrees in this patient’s L knee and so he is actually in varus mechanically. Medial compartment joint space narrowing and small osteophyte

34. Anatomy? View?

35. Anatomy? Patella View? Sunrise view

36. Pathology?

38. Patella fracture. Difficult to see on AP view.

39. Pathology?

40. Bicondylar tibial plateau fracture.

41. Anatomy?

42. This is a coronal plane MRI. What are the arrowed structures?

43. ACL PCL MCL Medial and lateral meniscii.

44. This is a saggital plane MRI. What compartment of the knee is this slice through?

45. What are these structures? The presence of the fibula tells us it is through the lateral compartment.

46. Patellar tendon (ligament) Anterior and posterior horns of the lateral meniscus The presence of the fibula tells us it is the lateral compartment.

47. What is this structure?

48. ACL

49. What is this structure?

50. PCL

51. Pathology?

52. Degenerative tear posterior horn medial meniscus (it’s not solid black like it should be). Healthy lateral meniscus is solid black

54. Pathology?

55. Fracture tibia and fibula Cast

56. Pathology?

58. Fracture of fibula (hard to see on lateral view - this is why it is often said that you MUST have two views)
