Background: Triceps tendon repair failures or chronic tears may require reconstruction. The appropriate reconstruction technique depends on the size of the defect and quality of the remaining native tendon tissue. Purpose: We present the case of a 60-year-old man who underwent direct repair of an acute triceps rupture, but suffered re-injury 3 months postoperatively after eccentric trauma. He was found to have recurrent rupture with significant retraction and compromised tendon tissue quality, and he was indicated for reconstruction. We present a surgical technique of Achilles tendon allograft reconstruction, augmented with native anconeus muscle/tendon. Methods: Using a posterior approach, the ulnar nerve was released and protected. The native triceps tendon remnant was absent; the triceps muscle was mobilized and débrided, and a 5-cm defect was noted. The anconeus was mobilized and incorporated into the reconstruction to provide native biologic augmentation. An Achilles tendon allograft was used and divided proximally into three equal limbs, each woven into the triceps muscle and secured with nonabsorbable suture. Two-millimeter-wide suture tape was woven into the graft and triceps in Krackow fashion. A double-row repair with suture anchors was performed into the olecranon, incorporating the native anconeus tissue and the allograft to complete the reconstruction construct. Results: The patient regained active elbow extension and has returned to daily exercise and use. Conclusion: Reconstruction of chronic, retracted triceps tears can be challenging. We present a technique of successful reconstruction incorporating both native anconeus tissue and Achilles allograft while reviewing other fixation options, challenges, and outcomes.
