A comparison of three methods of skin closure following repair of Achilles tendon rupture

Meticulous skin closure is required to avoid wound problems after Achilles tendon surgery. The purpose of our study was to compare postoperative complication rate, operation time, clinical outcome and patient satisfaction with the wound among two topical skin adhesives (2-octyl cyanoacrylate and n-butyl cyanoacrylate) and conventional nylon skin sutures in Achilles tendon repair surgery. We retrospectively reviewed the records 122 consecutive patients (40 patient in nylon skin suture, 43 patients in 2-octyl cyanoacrylate and 39 patients in n-butyl cyanoacrylate) who underwent surgical repair for acute Achilles tendon rupture between 2012 and 2016. The primary outcome measure was the development of complications in the wound. Secondary outcome measures included the operative time, the Achilles Tendon Total Rupture Score (ATRS) and patient satisfaction with the wound. There was no difference in complication rate in the wound (p = 0.694) and in ATRS (p = 0.824) among patients in the three groups. Mean operative time in nylon skin suture group was significantly longer than in the 2-octyl cyanoacrylate group and n-butyl cyanoacrylate group (p = 0.018 and p = 0.002, respectively). Patient satisfaction in the 2-octyl cyanoacrylate and n-butyl cyanoacrylate groups was significantly higher than in the nylon skin suture group (p = 0.015 and 0.018, respectively). The use of 2-octyl cyanoacrylate and n-butyl cyanoacrylate topical skin adhesives for skin closure following repair of Achilles tendon rupture has equivalent effectiveness and safety compared to conventional nylon skin suture, but higher patient satisfaction. Despite its higher cost, these topical skin adhesives are viable alternatives for wound closure in patients who regard cosmetic outcomes as important.
