Background: Acute Achilles tendon rupture (AATR) is a common injury of the foot and ankle. So far, the optimal management of AATR remains controversial. The target of the present retrospective study was to describe a new operative technique for percutaneous repair of AATR and evaluate efficacy of the technique.
Methods: In the present study, 32 patients were enrolled with AATR treated with the percutaneous oval forceps suture-guiding method with anchor nails from Jan 2014 to Jan 2017. The operation duration and length of incision were collected. The functional outcomes were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) score, Achilles tendon total rupture score (ATRS), range of motion (ROM) of the ankle and plantar flexion strength ratio at the last follow-up. The postoperative sports activity level and complications were also recorded.
Results: The mean operation duration and length of incision were 24.5 min and 2.0 cm. Whilst patient reported outcome questionnaires like AOFAS and ATRS showed good results, ROM of the ankle was quite low with only 16.5 degrees. Plantar flexion strength ratio was lower post surgery, as well. As for the postoperative sports activity level: 26/32 cases (81.3%) returned to former sports activity level; 4/32 cases (12.5%) showed a decline in sports activity level; 2/32 cases (6.2%) gave up on sports. The overall complication rate was 6.2%, one sural nerve damage and one fusiform thickening were found in the study.
Conclusion: The percutaneous oval forceps suture-guiding method with anchor nails is a new considerable surgery method with adequate healing rates and an alternative to existing surgical procedures.
