Abstract: Introduction: Failure of reconstruction and Wound complications following open repair for Achilles tendon ruptures remain the subject of significant debate. The aim of this study is to investigate the effects of Flexor Hallucis Longus tendon transfer to avoid complications after open repair.
Methods: In this case series study, open repair was performed for 6 patients with chronic tendo Achilles rupture. After the tendon was debrided, ipsilateral FHL tendon was harvested from the same incision, tendo Achilles reconstruction was done. The deep fascia and paratenon was used to cover the tendon. Anterior below knee splint applied for 6 weeks. Patients were followed for 6 months and any wound complication was recorded. During the last visit, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hind foot score was completed for all patients. Calf circumference and ankle range of motion were measured and compared with the contralateral side. Patients were asked about returning to previous activities after 6-8 weeks.
Results: None of the patients developed wound infection. None of the patients had any discomfort around the operation area, limitation with footwear, sural nerve injury, re-rupture, and skin adhesion. The AOFAS score averaged 92.5 ± 3. 1 patient was unable to do sports activities because of moderate pain in heavy physical exercises. The calf circumference and ankle ROM were similar between healthy and operated sides.
Conclusion: The present study showed that FHL tendon transfer has excellent result for chronic tendo Achilles tendon reconstruction.
