Patient-Reported Outcomes of Achilles Tendon Repair Using the Modified Gift-Box Technique With Nonabsorbable Suture Loop: A Consecutive Case Series

We sought to determine the early range of motion, complication rates, and 1-year patient-reported outcomes following Achilles tendon repair, using a modified gift-box suture loop technique. Sixty consecutive patients (49 males, mean age 36.2 ± 9.9 years) who underwent Achilles tendon repair with a modified gift-box suture loop technique performed by a single surgeon were prospectively enrolled. The range of motion at the final follow-up visit (mean 6 months) and the Achilles tendon rupture score (ATRS) and the complication rates at 1 year were obtained with 83% follow-up. The predictors of complications and ATRS were assessed. The mean operative time was 63.1 ± 10.8 minutes, which decreased throughout the case series (r = 0.46, p <.001). The mean plantarflexion at the final office evaluation was 31.7° ± 6.2°, dorsiflexion was 11.7° ± 6.3°, and total ankle arc of motion was 43.6° ± 9.7°; longer length of follow-up was associated with greater dorsiflexion (p =.008) and the total arc of motion (p =.008) but not with plantarflexion (p =.16). The overall rerupture rate was 1.7% (1 patient), wound complication rate was 1.7% (1 patient), and the overall complication rate was 6.7% (4 patients). No predictors of complications were identified. Complication rates did not differ between the first 30 (6.7%) cases and second 30 (6.7%) cases. The mean ATRS at 1 year was 81.8 ± 16.8 points. The rerupture and overall complication rates by 1 year were low. The range of motion, particularly dorsiflexion, improved through at least 6 months. Diabetic patients had lower 1-year ATRS than nondiabetic patients using this technique.
