Surgical Technique
The triple tibial osteotomy involves removing a horizontal small wedge of bone (average 12 degrees) halfway along a vertical osteotomy in the tibial tuberosity. Firstly by removing the wedge of bone, the tibial plateau is levelled. Secondly as the horizontal defect created by removing the wedge is closed down, the tibial tuberosity is itself advanced by several millimetres. This compares with an average of 20 degrees plateau levelling required for the TPLO and 9-12mm of tibial tuberosity advancement with the TTA.
Return to normal function is rapid, with most dogs having good use of the leg and a normal appearing gait within 3–4 months; long-term progression of arthritis is minimal.
