alignment

Principle

Correct alignment and soft tissue balancing

- two of the most important aspects of successful TKR

Technical Goals

1.  Restoration of mechanical alignment

- forces of the leg pass through the centre of the hip, knee and ankle

Issues

Limb alignment

Risk that late posterolateral corner reconstruction will fail in the setting of the varus knee

- varus knee alignment and varus thrust in stance phase

- consider osteotomy first in this setting
