Understanding Achilles Tendon Rupture and Surgery
Anatomy and Function of the Achilles Tendon
The Achilles tendon is the largest and strongest tendon in the human body. It’s located at the back of the ankle, connecting the powerful calf muscles (gastrocnemius and soleus) to the calcaneus (heel bone). This crucial tendon is responsible for plantarflexion of the foot, which is the motion that allows you to point your toes, push off when walking or running, and jump. Without a healthy Achilles tendon, many everyday activities would become incredibly difficult or impossible.
Causes and Symptoms of Achilles Tendon Rupture
Achilles tendon ruptures often occur during activities that involve sudden starts, stops, or changes in direction, such as basketball, tennis, and running. While athletes are at higher risk, anyone can experience this injury. Common causes include:
- Sudden forceful plantarflexion of the foot
- Overstretching the tendon
- Direct trauma to the tendon
- Degeneration of the tendon over time (tendinopathy)
The hallmark symptom of an Achilles tendon rupture is a sudden, sharp pain in the back of the ankle, often described as feeling like being kicked or shot. Other symptoms may include:
- A popping or snapping sound at the time of injury
- Difficulty walking or standing on tiptoes
- Inability to push off with the injured leg
- Swelling and bruising around the ankle
Surgical Options for Achilles Tendon Repair
When surgery is deemed necessary, there are two primary surgical approaches:
- Open Repair: This involves making an incision over the ruptured tendon to directly visualize and repair the torn ends. The surgeon will carefully suture the tendon back together, ensuring proper alignment and tension.
- Percutaneous Repair: This minimally invasive technique involves making several small incisions instead of one large incision. The surgeon uses specialized instruments to guide sutures through the tendon and repair the tear.
The choice of surgical approach depends on several factors, including the severity of the rupture, the patient’s overall health, and the surgeon’s preference. Both methods have shown success in restoring tendon function.
The Immediate Post-Operative Phase (Weeks One and Two)
What to Expect Immediately After Surgery
Expect some pain and discomfort following the procedure. Pain management will typically involve prescribed pain medication, as well as elevation and ice. Your leg will be immobilized in a cast or boot, positioned in plantarflexion to reduce tension on the repaired tendon. During this phase, you will be non-weight bearing, meaning you cannot put any weight on the injured leg.
Essential Post-Op Care
- Wound Care: Follow your surgeon’s instructions carefully regarding wound care. Keep the incision clean and dry to prevent infection.
- Elevation: Elevate your leg above your heart as much as possible to reduce swelling.
- Controlling Swelling: Apply ice packs to the injured area for twenty minutes at a time, several times a day.
Potential Complications in the Early Stages
While complications are relatively rare, it’s important to be aware of the potential risks, including:
- Infection
- Blood clots
- Nerve damage
- Wound healing problems
Contact your surgeon immediately if you experience any signs of infection, such as increased pain, redness, swelling, or drainage from the incision site.
The Early Rehabilitation Phase (Weeks Two to Six)
Transitioning to Partial Weight-Bearing
Under the guidance of your surgeon and physical therapist, you will gradually transition to partial weight-bearing. This typically involves using crutches or a walker to offload some of your weight. The amount of weight you can bear will be carefully monitored and increased as tolerated.
Introduction to Gentle Range of Motion Exercises
Gentle range of motion exercises are crucial for preventing stiffness and promoting tendon healing. These exercises may include:
- Ankle pumps (moving your foot up and down)
- Alphabet tracing (using your foot to trace the letters of the alphabet)
The importance of controlled movement cannot be overstated. Avoid pushing yourself too hard, as this could jeopardize the healing tendon.
Physical Therapy Begins
Physical therapy plays a vital role in Achilles tendon surgery recovery. Your physical therapist will conduct an initial assessment to evaluate your range of motion, strength, and overall function. Goals for this phase include:
- Reducing pain and swelling
- Improving range of motion
- Initiating gentle strengthening exercises
- Providing education on proper body mechanics
Your physical therapist may use manual therapy techniques, such as soft tissue mobilization, to improve tissue mobility and reduce pain.
The Intermediate Rehabilitation Phase (Weeks Six to Twelve)
Increasing Range of Motion and Flexibility
- Stretching exercises, such as calf stretches, help to improve flexibility and prevent stiffness.
- Calf raises, performed in small increments, help to strengthen the calf muscles and improve ankle mobility.
Strengthening Exercises
- Resistance bands can be used to perform a variety of strengthening exercises, such as plantarflexion, dorsiflexion, and inversion/eversion.
- Bodyweight exercises, such as heel raises, can be gradually introduced to further strengthen the calf muscles.
Proprioceptive Training
- Balance exercises, such as standing on one leg, help to improve balance and coordination.
- Coordination drills, such as agility ladder exercises, help to improve footwork and agility.
The importance of regular physical therapy sessions
The importance of regular physical therapy sessions cannot be overstated. Your physical therapist will monitor your progress, adjust your treatment plan as needed, and provide guidance on how to safely progress your exercises.
The Advanced Rehabilitation Phase (Months Three to Six)
Gradual Return to Activities
- Walking without assistive devices
- Light impact activities (e.g., swimming, cycling)
Sport-Specific Training (if applicable)
- Agility drills
- Plyometrics
- Gradual increase in intensity
Monitoring for Pain and Swelling

Conclusion
Achilles tendon surgery recovery is a marathon, not a sprint. While the typical recovery timeline ranges from six to twelve months, the journey is highly individualized. Patience, dedication, and close communication with your medical team are essential for a successful outcome. Embrace the process, listen to your body, and celebrate each milestone along the way. With proper care and a structured rehabilitation program, you can regain full function, return to your favorite activities, and enjoy a fulfilling life. Remember, a full and active life is achievable after Achilles tendon surgery with the right approach.
