Comparison of the short-term complications of TTA-rapid and modified cTTA procedures

The objective of this retrospective study was to determine the complications of the first 30 tibial tuberosity advancement rapid (TTA-rapid) and 30 modified circular tibial tuberosity advancement (mcTTA) procedures performed by our team, and to compare the results with the findings reported in the literature. Our research was based on 30 procedures in each group. All dogs were client-owned. Data were collected only for the study of cases that had a minimum follow-up period of 3 months. Intraoperative (IO) and postoperative (PO) complications were assessed, with the latter divided into two subgroups: major and minor. Results obtained for the TTA-rapid group: IO complications 23.3% (7/30), major PO complications 13.3% (4/30), minor PO complications 16.7% (5/30). Results of the mcTTA group: IO complications 0% (0/30), major PO complications 3.3% (1/30), minor PO complications 20% (6/30). Comparing the complication rates, we found that there was a significant difference between the two groups in the occurrence of IO complications (P = 0.01054); however, there was no significant difference in the incidence of major (P = 0.3533) and minor (P > 0.9999) PO complications between groups. Our results are consistent with the findings reported in the literature and suggest that both techniques are efficient and carry a relatively low complication rate.
