What is theTibial Tubercle?

The tibial tubercle is a lump at the top of the leg bone (tibia) where the patella ligament attaches. It is important in allowing the knee to straighten from a bent position (extension) as well as determining tracking of the kneecap (Patella).

What happens during a TTO?

During a TTO the tubercle is detached from the bone with a saw cut and moved to a new position and usually held in position to heal with screws.

The tubercle can be moved more towards the inner side of the knee (medial), more towards the ankle (distal) or more away from the bone (anterior) depending on the patient’s anatomy and the indications to perform the surgery.

What are the indications to perform a TTO

The main indications are

Intractable kneecap pain
Recurrent kneecap instability where it is often combined with a ligament reconstruction
For surgical exposure during complex knee replacement surgery
TTO Railing Kneecap TTO to Realign the kneecap

After Your Replacement Surgery background

What happens
after surgery?

After surgery your leg will be in a brace. You’ll be able to bear full weight on the leg limited by pain. The brace will allow progressively more bend at the knee over a period of 8 weeks. This surgery will require intense rehabilitation (see rehab protocols) and involves significant muscle wasting which can take 9-12 months to rehabilitate from.
