High Tibial Osteotomy (Knee re-alignment surgery)

In younger patients affected by arthritis, it is preferential if possible to retain the patient’s own knee. In selected cases, where arthritis predominantly affects the inner (medial) aspect of the knee, a procedure to re-align the knee can be undertaken. This technique moves the mechanical (weight-bearing) axis of the knee, away from the arthritic painful side towards the outer (lateral) non-arthritic side.

These pre –operative x-rays show arthritis affecting the inner aspect of the knee and a limb alignment x-ray showing the mechanical axis passing through the inner aspect of the knee.


These post-operative x-rays show the knee following re-alignment surgery and how the mechanical axis has been moved to the outer aspect of the knee, taking the pressure off the inner arthritic aspect.
