What is the success rate of Achilles Tendon Surgery?


Achilles tendon injuries can be debilitating and require surgical intervention in some cases. Understanding the success rates of Achilles tendon surgery is crucial for patients and healthcare providers. This article delves into the factors that affect the success rates and the different types of surgeries involved.

Understanding the Achilles Tendon

The Achilles tendon is the largest and strongest tendon in the human body, connecting the calf muscles to the heel bone. Its primary function is to facilitate walking, running, and jumping. However, it is prone to injuries, with ruptures and tears being common occurrences.

Indications for Achilles Tendon Surgery

Surgery is typically considered for Achilles tendon injuries when conservative treatments like rest, physical therapy, and immobilization fail to provide satisfactory results. Indications for surgery include:

  • Complete Achilles tendon rupture
  • Chronic Achilles tendonitis
  • Severe tendon degeneration
  • Failed non-surgical treatment

Types of Achilles Tendon Surgery

There are two main types of Achilles tendon surgery:

4.1. Open Surgery

  • Involves making a large incision to access the damaged tendon.
  • Torn ends of the tendon are sutured back together.
  • Requires a longer recovery period.

4.2. Minimally Invasive Surgery

  • Utilizes smaller incisions and specialized instruments.
  • Often referred to as percutaneous or endoscopic surgery.
  • Typically results in quicker recovery times.

Factors Affecting Success Rates

Several factors influence the success rates of Achilles tendon surgery:

5.1. Patient Factors

  • Age: Younger patients tend to have better outcomes.
  • Health: Overall health and fitness levels play a role.
  • Compliance: Adherence to postoperative instructions and rehabilitation is crucial.

5.2. Surgical Technique

  • The surgeon’s experience and skill significantly impact the outcome.
  • Proper alignment and tensioning of the tendon during surgery are essential.

5.3. Postoperative Care

  • Follow-up care, physical therapy, and rehabilitation are vital.
  • Compliance with rehabilitation exercises improves long-term success.

Success Rates of Achilles Tendon Surgery

6.1. Open Surgery Success Rates

  • Success rates typically range from 70% to 90%.
  • Variability depends on patient factors and surgical technique.

6.2. Minimally Invasive Surgery Success Rates

  • Success rates are generally comparable to open surgery.
  • Minimally invasive techniques offer advantages like smaller scars and reduced risk of infection.

Complications and Risks

Achilles tendon surgery, like any medical procedure, carries risks. Potential complications include infection, delayed healing, nerve damage, and rerupture. These risks are relatively low but should be discussed with the surgeon before the procedure.

Rehabilitation and Recovery

Rehabilitation is a crucial aspect of Achilles tendon surgery. It typically involves a progressive program of physical therapy and exercise to restore strength and flexibility. Full recovery may take several months, with a gradual return to normal activities.


The success rate of Achilles tendon surgery depends on various factors, including patient characteristics, surgical technique, and postoperative care. Both open and minimally invasive surgeries have demonstrated favorable outcomes, with success rates ranging from 70% to 90%. Patients should consult with their healthcare providers to determine the most appropriate treatment approach and understand the potential risks and benefits of surgery. Adherence to postoperative rehabilitation and care instructions plays a pivotal role in achieving the best possible outcome following Achilles tendon surgery.
