Outcomes and Complications of Open Versus Minimally Invasive Repair of Acute Achilles Tendon Ruptures: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: An acute Achilles tendon rupture is one of the most common sports injuries, affecting 18 per 100,000 persons, and its operative repair has been evolving and increasing in frequency since the mid-1900s. Traditionally, open surgical repair has provided improved functional outcomes, reduced rerupture rates, and a quicker recovery and return to activities at the expense of increased wound complications such as infections and skin necrosis compared with nonoperative management. In 1977, Ma and Griffith introduced the percutaneous approach, and over the following decades, multiple improved techniques, and modifications thereof, have been described with comparable outcomes with open repair.
