Objectives: To describe and compare the use and effectiveness of a single intra-articular injection (IA) of triamcinolone acetonide (TA), hyaluronan (HA), and a combination of both (TA+HA) in police working dogs with natural occurring hip osteoarthritis (OA).
Study Design: Prospective, randomized, single-blinded study.
Sample Population: Thirty animals with naturally occurring hip OA.
Methods: Animals were randomly divided in three groups: GT, treated with 20 mg of TA per hip joint; GH, treated with treated 20 mg of HA per hip joint; and GTH, treated with a combination of 20 mg of TA and 20 mg of HA per hip joint. Response to treatment, measured by the Canine Brief Pain Inventory (divided in Pain Interference Score-PIS and Pain Severity Score-PSS) and the Hudson Visual Analog Scale (HVAS), was evaluated in seven different time points: T0 (before treatment), T1 (after 15 days), T2, T3, T4, T5, and T6 (after 1, 2, 3, 4, and 5 months, respectively). Results were compared using a Kruskal-Wallis test or a Wilcoxon signed ranks test, and p < 0.05 was set.
Results: Comparing results of the different time points considered with T0, significant differences were registered in GH at T1 for HVAS (p = 0.03) and PIS (p = 0.04); and in GTH at T1 (p = 0.05 for HVAS and p < 0.05 for PIS), T2 (p < 0.04 for PIS), T3 (p < 0.03 for HVAS and p = 0.05 for PIS), T4 (p < 0.03 for HVAS and p < 0.05), and T5 (p < 0.05 for HVAS). No significant differences were found between groups when comparing scores in each time point. Individual treatment is considered successful with a reduction of >= 1 for PSS or >= 2 for PIS. In GTH, treatment was successful in four animals between T1 and T5 (40%, n = 10) and three at T6-T7 (30%, n = 10) for PSS and three animals of GTH at T1 (30%), two at T2 (20%), three between T3 and T4 (30%), and two between T5 and T7 (20%)
