  • Fracture of femur in child

  • Anatomy?

  • PatellaFibular headMed & lat epicondylesMed & lat condylesMed & lat tibial plateaus

  • Pathology?

  • Varus knees with mild medial compartment degenerative arthritis.

    Patient has had a valgus producing osteotomy on R to relieve pressure on medial compartmentNormal is 5-10 degrees valgus alignment between the fermoral and tibial shafts. Is 0 degrees in this patients L knee and so he is actually in varus mechanically.Medial compartment joint space narrowing and small osteophyte

  • Anatomy?View?

  • Anatomy?PatellaView?Sunrise view

  • Pathology?

  • Pathology?

  • Patella fracture.Difficult to see on AP view.

  • Pathology?

  • Bicondylar tibial plateau fracture.

  • Anatomy?

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

  • ACLPCLMCL

    Medial and lateral meniscii.

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

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

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

  • What is this structure?

  • ACL

  • What is this structure?

  • PCL

  • Pathology?

  • Degenerative tear posterior horn medial meniscus (its not solid black like it should be).

    Healthy lateral meniscus is solid black

  • T2 weighted MRI of same degenerative tear posterior horn medial meniscus.

  • Pathology?

  • Fracture tibia and fibula

    Cast

  • Pathology?

  • Pathology?

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