Reconstruction of a chronically ruptured Achilles tendon using an internal brace: A case report

Abstract

Background: We reconstructed a chronically ruptured Achilles tendon and the associated scar tissue using braided polyblend polyethylene sutures (FiberWire; Arthrex Inc.; Naples, FL, USA) and anchors. Case presentation: A 68-year-old Japanese man, who was being treated for right Achilles tendinosis, felt pain in his Achilles tendon when walking and started to find plantar flexion of his ankle joint difficult. As his symptoms persisted, he visited us after 4 weeks. Surgery and orthotic therapy were recommended, but he did not want to undergo these treatments. However, he began to find walking difficult and so underwent surgery 6 months after suffering the injury. The interior of the tendon was curetted, and the ruptured region was subjected to plication using the surrounding scar tissue. Using the percutaneous Achilles repair system (Arthrex Inc.), FiberWire sutures were inserted, and two skin incisions were made on the medial and lateral sides of his calcaneus in the region surrounding the Achilles tendon attachment. SutureLasso (Arthrex Inc.) was passed through, and the proximal FiberWire suture was relayed and fixed with 4.75-mm SwiveLock (Arthrex Inc.). After surgery, his foot was fixed in plaster at 20° plantar flexion of his ankle joint. The plaster was removed 1 week after surgery, and after-treatment was initiated with active dorsiflexion training. No orthosis was used after surgery. As of 16 postoperative months, no re-rupture had occurred. Conclusions: This method might allow post-treatment rehabilitation, and so on, to occur earlier, and, hence, could become an option for the reconstruction of chronically ruptured Achilles tendons.
