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.
