Chronic Achilles rupture reconstructed with Achilles tendon allograft: a case report.

Chronic ruptures of the Achilles tendon are more difficult to treat than acute tendon rupture. It has been shown that surgical treatment of chronic Achilles tendon rupture provides better functional results than nonoperative treatment. We present a case of neglected Achilles tendon rupture with a 12-cm defect that was repaired using an Achilles tendon allograft with interferential screws to fix the graft in the calcaneus. The patient recovered his ankle function to normal activities after rehabilitation.
