Abstract:
PURPOSE: The purpose of this study was to evaluate the clinical results of the old Achilles tendon rupture treated with modified flexor hallucis longus (FHL) tendon transfer. MATERIALS AND METHODS: Seventeen patients with old Achilles tendon rupture treated with modified FHL tendon transfer between March 2004 and February 2008 were enrolled in this study. Technically FHL was pass through the distal portion of the ruptured tendon instead of the drilled hole made on the calcaneus. The mean age of the patients was 37 years (range, 22~67 years), mean follow-up period was 28 months (range, 12~30 months). Patients' subjective satisfaction, calf circumferential diameter, range of motion of ankle and AOFAS ankle-hind foot score and Arner-Lidholm score was evaluated. RESULTS: The average gap between the ruptured tendon was 52 mm (range, 47~56 mm). The AOFAS score improved from 47 pre-operatively to 91 points at the last follow-up. Sixteen patients were satisfied with the result free from discomfort, a patient had mild discomfort who had DM. fourteen patients had decreased range of motion less than 5 degrees while 2 patients had more than 7 degrees decrease compared to the intact side but had no discomfort in daily activities. Nine patients had less than 1 cm calf circumferential diameter difference and 7 patients had 1 to 3 cm diameter difference compared to the intact side. One who had more than 3 cm diameter difference had deteriorated muscle strength. CONCLUSION: Modified FHL tendon transfer can be a useful technique for the treatment of old Achilles tendon rupture when the gap is with large gap placed too proximal.
