Background:
Acute Achilles tendon rupture is a common injury. The optimal management of acute Achilles tendon rupture remains controversial.
Purpose:
Compare the efficacy and complications of minimally invasive repair with improved oval forceps suture-guiding method and open repair with modified Kessler method.
Study Design:
A clinical measurement.
Methods:
We enrolled 60 patients from Jan 2017 to Jun 2019. Patients were randomly divided into Group Mini (30 cases) and Group Open (30 cases). The operation duration and length of incision were compared. The functional outcomes were evaluated using the American Orthopedic Foot and Ankle Society score, Achilles tendon total rupture score, range of motion of the ankle and plantarflexion strength ratio. The time from surgery to return to work and sports were recorded and the complications were also assessed.
Results:
The operation duration and length of incision in Group Mini were significantly less than that in Group Open, which reduced wound complications and improved cosmesis. However, there were no significant differences between the two groups in term of the functional outcomes. The time from surgery to return to work and sports in Group Mini were significantly shorter than that in Group Open. As for complications, the postoperative complication rate in Group Mini were significantly lower than that in Group Open.
Conclusions:
There may be benefits to the minimally invasive approach in the treatment of acute Achilles tendon rupture compared to open.
