Achilles Tendon Reconstruction With Bone Block Allograft:Long-Term Follow-Up of Two Cases.

Abstract

The treatment of neglected or chronically ruptured Achilles tendon is challenging. Various treatments for large defects associated with chronic Achilles ruptures have been described. Many surgeons recommend the use of a tendon transfer, turndown rotational flap, advancement flap, or reconstruction with Achilles tendon allograft with calcaneal bone block. Long-term outcomes of these procedures are unknown. We present 2 cases with the use of an Achilles tendon with calcaneus bone block allograft. At >8-year follow-up duration, both patients are afforded satisfactory levels of activity and are without pain or gait disturbance. This procedure is a viable option for Achilles ruptures with large defects, ruptures with small intact distal tendon portions, or re-ruptures of previously repaired Achilles tendons. The long-term outcomes of these case reports suggest that Achilles tendon reconstruction with bone block allograft is a viable option.
