This article describes two cases of augmentation of ruptured tendon with fresh frozen Achilles tendon allograft (FFATA) in dogs. Case 1 was a two-year-old crossbreed dog (29 kg) that presented with an open wound on the right forelimb and with complete rupture of the flexor carpi ulnaris and superficial digital flexor tendons. Case 2 was a four-year-old crossbreed dog (4 kg) with partial ruptures of the patellar tendon and detachment of the tibial tuberosity in the right hind limb. In both cases, the ends of the ruptured tendon were sutured and apposed after debridement. To minimize suture failure, FFATA (cut to sufficient size) was placed across the primary suture with tension and sutured to the host tendon. In addition, Case 2 received a Krackow suture through a transverse bone tunnel made in the tibia to fix the patellar tendon along with the tibial tuberosity in situ. The surgical areas healed without any evidence of exaggerated inflammatory response or clinical signs consistent with rejection of the allograft. Both the dogs had normal ambulation and weight bearing on the affected limb 12 weeks postoperatively. No postoperative complications were observed during a one-year follow up period except for slight contracture of the carpus and digits of the affected limb in Case 1. Thus, ruptured tendons can be successfully repaired using suture and augmentation with FFCTA. Augmentation with FFATA may provide additional stability, which counters tension on the primary repair and reduces the chance of gap formation or suture failure in case of reconstruction of the damaged tendon in dogs.
