Tibial Tubercle Transfer (TTT)
Tibial Tubercle Transfer (TTT) is what orthopaedic surgeons call a realignment procedure. Think about how we straighten the knee. The quadriceps muscles on the front of the thigh contract. They pull on the patella, which is connected to the tibia (shin bone) by the patellar tendon, and the knee straightens. This works well when everything is nicely centred at the front of the knee. Unfortunately, things do not always line up, and when they don't the knee cap tilts to the outside of its groove. This is called a maltracking patella.

Is Tibial Tubercle Transfer the surgery you need?
If the knee cap isn't running smoothly in the centre of the knee, it can be realigned by tibial tubercle transfer. This surgery for knee cap maltracking is also called patellofemoral realignment. You might benefit from TTT if you have:
What is involved in a Tibial Tubercle Transfer procedure?
Firstly, Dr Colvin will do a Knee Arthroscopy to smooth damage to the articular cartilage to perform a lateral release to free up the knee cap.
Then the knee cap is centralised by cutting the tibia bone (osteotomy) where the patellar tendon attaches. This bump of bone just below the patellar is called the tibial tuberosity. It is shifted inwards about one centimetre and repositioned with metal screws. At this time, everything should line up nicely.
