How Long Does an Achilles Tendon Surgery Take?

The Achilles tendon is the largest and strongest tendon in the human body, connecting the calf muscles to the heel bone. This structure is responsible for the powerful push-off motion required for walking, running, and jumping. A sudden, forceful contraction, often during sports, can cause a complete tear, known as an Achilles tendon rupture. For active individuals, surgical repair is frequently the preferred treatment method to restore the tendon’s original length and tension, necessary for regaining full strength and function.

Defining the Types of Achilles Tendon Surgery

Surgical intervention for a ruptured Achilles tendon generally falls into two broad categories: open repair and minimally invasive techniques. The open repair method involves a longer incision made along the back of the lower leg, allowing the surgeon direct visualization of the two torn tendon ends. This approach enables the surgeon to precisely stitch the tendon ends back together, often preferred for chronic ruptures or cases requiring augmentation with a separate tendon graft.

Minimally invasive or percutaneous repair utilizes several smaller incisions, or punctures, through which specialized instruments and sutures are passed. This technique repairs the tendon without fully exposing the entire area, resulting in a smaller surgical scar and potentially fewer wound-related complications. While open repair offers better visibility, the percutaneous method is often chosen for acute ruptures due to its reduced disruption of the surrounding soft tissues.

Factors Influencing the Surgical Duration

The actual time a patient spends in the operating room under anesthesia can vary significantly based on the chosen technique and the injury’s complexity. A straightforward percutaneous repair is the quickest, with operative times around 30 to 45 minutes. Open repair procedures, which require a longer incision and more extensive closure, generally take longer, often ranging from 60 to 90 minutes.

The most significant factors extending the surgical duration are the condition of the tendon ends and the need for additional material. If the rupture has frayed or retracted ends, or if it is a re-rupture, the surgeon may need more time to prepare the tissue for a solid connection. Procedures requiring a tendon graft, such as a tendon transfer to reinforce the repair, can push the total surgical time to 90 minutes or even two hours, excluding preparation and recovery periods.

Time Needed for Pre-Operative Preparation

The total time spent at the hospital begins well before the surgical repair starts, as the pre-operative process can easily add one to two hours to the day’s timeline. Patients first check in and complete administrative paperwork, followed by changing into a surgical gown. Next, the patient meets with the surgical team, including the operating room nurse and the anesthesiologist, to review the procedure and address any final questions.

A registered nurse will place an intravenous (IV) line for fluids and medication, and the specific surgical site is marked to ensure accuracy. Anesthesia induction is a key part of preparation, often involving a regional nerve block to numb the leg, followed by general anesthesia or sedation. Patients must strictly follow instructions regarding when to stop eating or drinking, as failing to do so can lead to the cancellation of the procedure.

Immediate Post-Operative Monitoring and Discharge

Once the Achilles tendon repair is complete and the incision is closed, the patient is moved to the Post-Anesthesia Care Unit (PACU) for immediate monitoring. This stage focuses on safely waking the patient from anesthesia and ensuring vital signs, such as heart rate and blood pressure, are stable. Pain management is also a primary concern, with nurses administering medication to control post-operative discomfort as the regional nerve block or general anesthesia begins to wear off.

The time spent in the PACU is between one and three hours for an outpatient surgery, depending on how quickly the patient recovers from the anesthetic. Before being discharged home, the patient must meet specific criteria, including being fully awake, having stable vital signs, and demonstrating the ability to safely mobilize with assistive devices like crutches. A responsible adult must be present to accompany the patient home, as the residual effects of anesthesia and pain medication make driving or independent travel unsafe.
