Knee motion is more complex than a simple hinge joint; it glides, rotates and flexes. Knee Kinematics is controlled by 3 things: articular geometry, soft tissue tension, and muscle forces. We examine each.
Explain relationship between mechanical axis, anatomic axis, the Knee Angle and the joint line angle.
TKA aims to recreate the mechanical axis of the native leg, however, it does not recreate the same angle of joint line. Explain the differences in alignment and knee angles between native knee and TKA.
Explain the theory behind each of the cuts. How to achieve mechanical alignment, dial in rotation, restore the joint line and size the implant.
Explain how component positioning, particularly rotation of the femoral or tibial implant, affects patellar tracking.
Explain impact of component positioning on ultimate range of motion and knee kinematics.
