In percutaneous surgery, several small incisions are made in your lower leg instead of one large incision. Percutaneous surgery, while less invasive than open surgery, can cause some unexpected problems.
Advantages of percutaneous repair over open surgery include:
- Significantly less expensive
- Shorter surgery time
- Less damage to growth factors and blood clot around ruptured ends
- Less cosmetic scarring
- Lesser risk of infection
Disadvantages of percutaneous repair over open surgery include:
- Hard to visualize if the two ends of the ruptured tendon have been exactly connected to each other (i.e., also referred to as “coaption” or “apposition”). It should be noted that the use of intra-operative ultrasound as well as endoscopy in the hands of an experienced surgeon nowadays makes error rates in tendon apposition negligible.
- Chances of damaging sural nerve higher.
- According to some studies, complete tendon gap closure after percutaneous repair takes several weeks longer than after open surgery.
