[Objective] To compare the clinical outcomes of minimally invasive repair and traditional open repair for acute Achilles ten- don injury. [Methods] From 2016 to 2020, a total of 59 patients underwent surgical treatment for acute Achilles tendon rupture. Among them, 30 patients were treated with minimally invasive repair (minimally invasive group), while the remaining 29 patients received tradition- al open repair (traditional group) . The data of perioperative period and follow-up period were compared between the two groups. [Results] All the patients in both groups had operation performed successfully. The minimally invasive group proved significantly superior to the tra- ditional group in terms of operative time, total incision length, intraoperative blood loss and hospital stay (P＜0.05) . However, there was no significant difference in the incidence of postoperative complications between the two groups (P＞0.05) . At the latest follow up, there was no significant difference in average AOFAS score and ankle range of motion between the two groups (P＞0.05) . [Conclusion] Both minimally invasive repair and traditional open repair are effective treatment for acute Achilles tendon rupture. By contrast, the minimally invasive technique has the advantages of short hospital stay and less trauma.
