Short-term comparison of tibial tuberosity advancement and tibial plateau levelling osteotomy in dogs with cranial cruciate ligament disease using kinetic analysis.

OBJECTIVES: This study set out to compare the outcomes of tibial tuberosity advancement (TTA) and tibial plateau levelling osteotomy (TPLO) procedures in the treatment of dogs affected with unilateral cranial cruciate ligament disease (CCLD) based on subjective parameters and objective pressure platform analysis (baropodometry). METHODS: Twenty-seven adult dogs weighing over 20 kg that were presented with unilateral CCLD and were treated by the TTA (12 dogs) or TPLO (15 dogs) surgical procedure. Patient allocation to either group was based on tibial plateau angle (TPA), according to clinical guidelines (indication for TTA for dogs was a TPA up to 25°, and indication for TPLO was any TPA). Pressure platform analysis was performed prior to surgery and at four different postoperative time points (14, 30, 60 and 90 days). RESULTS: Limb function significantly improved following TTA and TPLO, with no significant differences between groups. CONCLUSION: The TTA and TPLO surgical procedures were considered to be equally effective in promoting weight bearing capacity recovery in dogs affected with unilateral CCLD under the conditions of this trial.
