The goal of this design project was to create an optimal fixation system to stabilize the stifle joint for a circular tibial tuberosity advancement procedure to treat canine CCL rupture or instability. Six designs were modeled via CAD; preliminary evaluations were made and three designs were manufactured. Prototypes were assembled on nine canine cadaver tibias and tested via tension in the patellar tendon. Loading was applied cyclically at stifle forces during walking and running. The Modified TTA design displayed the lowest failure loads (average=477N) and highest osteotomy rotation; the Triangle design showed the most traumatic failure in the bone. The Modified TPLO design exhibited the highest performance (failure load average=1234N) and minimal osteotomy rotation and displacement.
