The evolution of the tissue treated with autologous PRP showed a positive tendency over time, while the PCB group was negative. Nevertheless, at 19 weeks of age, the PRP treatment did not show better results than the PCB, both showing the characteristics of fibrocartilaginous tissue. Likewise, none of the two treatments produced a repair tissue as the healthy cartilage.

A nine-year-old English bulldog presented with an acute history of dyspnoea, tachycardia and discomfort localising to the ventral thorax following a fall down the stairs that morning. After the dog was stabilised, thoracic radiographs revealed a luxation of the third and fourth sternebrae with dorsal displacement of the caudal segment. The sternum was reduced and stabilised with a contoured 12-hole 3 · 5-mm dynamic compression plate applied to the ventral surface of the sternum. The dog's initial recovery was rapid, cardiorespiratory parameters returning to normal in the first 24 hours. For 2 weeks postoperatively the dog exhibited difficulty in rising from a prone position. After this time there was a full recovery. Clinical examination at 8 months postoperatively did not reveal any abnormalities. Telephone follow-up was performed at 18 months and no complications or cardiorespiratory compromise were reported. To the authors' knowledge, this is the first reported case of a traumatic dislocation of the sternum and its management in the dog.

Many surgical techniques have been described in the literature to repair chronic tendon or ligament ruptures. Although direct approximation of the edges is the surgical technique of choice, the use of synthetic, fascia lata, semitendinosus muscle, and small intestinal submucosa grafts has been described to repair large defects or augment tenous repairs. The aim of this paper was to present the long-term outcome of two clinical cases using a common calcaneal tendon cadaver allograft with subsequent application of platelet-rich plasma for chronic ruptures diagnosed by ultrasound, with a chronic defect between both edges. Twenty-four months after common calcaneal tendon rupture and 12 mo after patellar ligament rupture, orthopedic follow-up of both patients showed complete functional recovery and ultrasound findings were consistent with correct integration of the graft in both cases.
