In the US, by far the most common treatment choice for an achilles tendon rupture is an open surgery. In this type of surgery, one large incision is made at the back of the leg in order to access the tendon . If the gap between ruptured tendon ends is too large, a tendon transfer from the toe or other place is often necessary.
There are many variations in surgical technique, type of stitches used, type of anesthesia, and more. Below, I will post the best links I can find related to open surgery related articles, studies and videos.
