Patient overview of knee osteotomies

Osteotomies around the knee involve cutting the bone of the tibia and/or femur to change the alignment of the leg, often from bow leg or knock knee to straight, so the 'plumb line'/alignment is improved to offload the 'bad side' of the knee.

​

This is often a way of prolonging an active lifestyle/delaying a knee replacement in the young to middle age adult.

Severe rotation/torsion- On the left the feet face forward but the knee cap faces excessively inward, on the right with the knee cap facing forward, the feet face excessively outward/sideways.

Sagittal plane osteotomy

TDO- tibial deflexion osteotomy/ slope decreasing osteotomy/ ACL osteotomy

The tibia has a normal amount of slope or incline, in those who re rupture their ACL, they commonly have increased slope which increases the stress on the ACL.

​

Dr Dan learnt the procedure while on fellowship at the Lyon Knee School, where the surgery was first performed, and has published extensively on the procedure.

Tibial Tubercle Osteotomy

TTO/ Patellar realignment

The tibial tubercle is where the patella tendon/ligament inserts. By modifying the position of the tibial tubercle, the knee cap/patella position can be changed, improving patella tracking, offloading certain areas of the cartilage and forces in the patellar tendon can be manipulated, making it a useful surgery for patella dislocations, pain and tendinopathy.
