This prospective study evaluated the effect of tibial tuberosity advancement (TTA) on lameness, thigh circumference, range of motion (ROM), and radiographic osteoarthritis (OA) scores at 6 wk, 6 mo, and 1 y after surgery in 24 client-owned dogs with cranial cruciate ligament (CrCL) deficiency. Complications associated with TTA were also assessed. A significant improvement in lameness score and thigh circumference was observed in CrCL deficient limbs that received TTA, but no significant overall change in range of motion occurred in the affected limbs over the course of the study. Post-operative complications were identified in 33.3% of the dogs. This study demonstrates that TTA results in significant clinical improvement in patients up to 1 y after surgery. However, 21% of the dogs had post-operative recurrent lameness.
