  • 4. 
    Which key design changes improved kinematics by reducing early rollback (posterior cam & post engage later in flexion ~60-70⁰)? 
    • A. 

      Posterior cam elevated superiorly and cam reduced in size

    • B. 

      Post shifted 2mm anteriorly

      A & B

    • E. 

      A & C

  • 5. 
    Why has the JII PS box increased in size?
    • A. 

      Reduce early rollback

    • B. 

      Reduced strain of popliteal tendon

    • C. 

      Reduced strain of IT and IT patella band

    • D. 

      To accept a constrained insert (bail out option)

    • E. 

      A & D

  • 6. 
    Although there are a number of changes it is most important to understand those that have specifically addressed the complications as seen with the JBCS. What are the Key changes to address IT band syndrome? Please choose all correct response/s below.
    • A. 

      Post height decreased (on average 2-3mm)

    • B. 

      Thinned anterior flange and reduced lateral condyle

    • C. 

      Post shifted posteriorly & posterior cam lowered inferiorly

    • D. 

      Post shifted anteriorly & posterior cam elevated superiorly

  • 7. 
    What changes to the original JBCS insert have been made to address the complication of dislocation?
    • A. 

      Post height increased (on average 2-3mm) and top of post “squared off”

    • B. 

      Post height decreased (on average 2-3mm) and top of post “rounded off”

    • C. 

      Post widened (on average 1-2mm)

    • D. 

      B & C

  • 8. 
    The original JBCS post was “rounded ” at the top which made it more susceptible to varus/valgus dislocation.
    • A. 

      True

    • B. 

      False

  • 9. 
    The stiffness associated with the original JBCS knee system was attributed to the excessive stresses placed on the soft tissues as a result of limited roll back of the femoral component.
    • A. 

      True

    • B. 

      False
