The objective of the TTA is to advance the tibial tuberosity, which changes the angle of the patellar ligament to neutralize the tibiofemoral shear force during weight bearing.

The TTO procedure has been developed as a hybrid of two previously available orthopaedic procedures, the tibial tuberosity advancement ( TTA ) and the tibial plateau leveling osteotomy ( TPLO ).

The main parameter in this test is " step-off ", which is the shortest distance from the femur to a hypothetical line that tangents the surface of the tibia from the tibial tuberosity and upwards.
14.
The Tightrope CCL technique utilizes a very strong suture material called FiberTape and isometric placement of small bone tunnels to provide bone-to-bone fixation while not causing the trauma of cutting through the bone of the tibia like a TPLO-tibial plateau leveling osteotomy or TTA-Tibial tuberosity advancement procedure.
