Background:
Surgical management of Achilles tendon rupture is still controversial: open techniques have a higher rate of soft tissue complications but a lower incidence of re-rupture than percutaneous tenorrhaphies. The aim of our retrospective study was to analyze and compare clinical and functional results in patients treated with either the conventional open or minimally invasive suture treatment with the Achillon® system.
Methods:
A retrospective review of 140 patients was performed; 72 were treated with open tenorrhaphy, 68 with the minimally invasive Achillon® suture system.
Results:
With a comparable re-rupture rate, there was a statistically significant reduction in surgical time, incidence of minor complications, time required to return to sport activities and return to work in the minimally invasive group.
Conclusions:
Achillon® mini-invasive suture system is a reliable tool for the Achilles tendon ruptures, able to reduce the incidence of soft tissues complications if compared to the classic open tenorrhaphy, while maintaining strength of the suture and leading to superimposed functional outcomes.
