Abstract
Background The aim of this study was to assess radiographic and clinical outcomes of a new modified approach on the basis of Bosworth’s technique in the treatment of infectious Achilles tendon rupture (IATR). Materials and methods 15 patients (9 males and 6 females; 15 feet; average age of 38.3 years) were included in the study. After infection, the wounds were transferred to our department for treatment (Figure 1).Radiographic and clinical outcome in terms of the American Orthopaedic Foot&Ankle Society score (AOFAS), the Victorian institute of sports assessment Achilles (VISA-A), and the Achilles tendon total rupture score (ATRS) were investigated at 6 months, 12 months, and 24 months postoperatively. Results Preoperative AOFAS, VISA-A, and ATRS showed statistically significant improvement (p≤0.05) from35.03±6.81 (25-45), 21.04±8.17 (5-45), and 20.08±8.93 (6-55) to 90.04±5.32 (82-97), 95.11±3.09 (79-99), and 96.34±3.61 (89-97) at the last follow-up, respectively. All patients could lift heel on one foot and return to work at 12 to 16 weeks after operation (average 14.2 weeks). Overall, No complications such as infection, skin necrosis, sural nerve injury, deep vein thrombosis, and re-rupture of Achilles tendon occurred at last follow-up. Conclusion The new modified approach of Bosworth’s technique provided powerful curative efficacy of infectious Achilles tendon rupture, without severe complications in terms of infection, skin necrosis, sural nerve injury, deep vein thrombosis, and re-rupture of Achilles tendon. Level of Evidence: Level IV, case series.
