True
False
Inadequate translation of the femur in flexion leading to increased eccentric loading of the ITB in some patients
The normal screw home position of the JBCS which allowed the knee to rest in its normal anatomical position
Excessive translation of the femur in flexion leading to increased eccentric loading of the ITB in some patients
A & B
Aseptic loosening of the tibial component
Excessive external rotation of the tibial component
Excessive posterior position of the tibial component
B & C
High flexion - during flexion the cam rises onto the post towards maximal flexion and in the case of a loose flexion space the cam could in theory become dislocated over the post
Low jump distance - due to the relative position of the cam, low height of the post combined with a rounded post design
Excessive femoral rollback - may contribute to consistent stretch on soft tissues leading to laxity, especially in flexion
All of the above
Excessive medial and lateral tibiofemoral posterior translation
Patella maltracking
Excessive medial and lateral tibiofemoral anterior translation
Chronic preoperative osteoarthritis
Design modification allowing the femur to rest posteriorly in full extension
The use of a knee joint balancer in order to optimally balance the flexion space
Design modifications in regards to the height of the polyethylene post in the JBCS implant as well as the relative position of the cam on the femoral component
B & C
True
