How Is an Achilles Tendon Rupture Treated?

Achilles tendon rupture is treated surgically or nonsurgically, depending on severity, age, and activity level. Both approaches involve initial immobilization followed by strengthening exercises that help restore calf muscle function and prevent re-rupture.

At Total Orthopedics and Sports Medicine, Dr. Charles Ruotolo, a Castle Connolly Top Doctor, specializes in treating Achilles tendon injuries and offers advanced surgical and nonsurgical treatments in Syosset. In case of completely torn tendons, he uses minimally invasive techniques to ensure faster healing and less scarring. In contrast, for a partial tear, he combines immobilization and strengthening exercises to help the injured leg heal naturally. Call us at 855-321-6784 to regain strength and mobility.

What Is the Best Treatment for Achilles Tendon Rupture?

Surgical repair is generally considered the best treatment for an Achilles tendon rupture, especially for athletes and active individuals who need to restore ankle strength, power, and function. However, non-surgical treatment may also provide excellent results for patients who are less active or have higher surgical risks.

Here’s how both treatment approaches help treat a torn Achilles tendon:

Surgical Treatment

In surgical treatment, a surgeon stitches the torn edges of the Achilles tendon back together, often using open or minimally invasive techniques. This approach provides stronger tendon repair, reduces the risk of re-rupture, and allows for earlier mobilization. In fact, an NCBI meta-analysis found that the re-rupture rate was 2.3% after operative treatment compared with 3.9% after non-surgical treatment.

Non-Surgical Treatment

Non-surgical treatment involves immobilizing the tendon with a cast or functional brace, which keeps the foot slightly pointed to allow natural healing. In addition, targeted exercises are gradually introduced to improve strength and range of motion. This method helps avoid surgical risks such as infection or nerve injury and is effective for less active patients or those with medical conditions that make surgery risky. Although recovery may take longer, careful rehabilitation ensures proper tendon healing and functional restoration.

What Causes an Achilles Tendon Rupture?

An acute Achilles tendon rupture occurs when sudden, forceful stress stretches the tendon beyond its limits. Common triggers of this force may include explosive jumps, sudden pivots in sports, tripping, or accidentally stepping into a hole. The tear may also occur due to some medications and underlying health conditions.

Here’s how these factors can lead to a severe Achilles tendon tear:

1. High-Impact Activities and Sports

Most Achilles tendon ruptures occur during physical activity, especially among people who exercise intensely but irregularly. These individuals are often called “weekend warriors” because they may be inactive during the week but participate in demanding sports or recreational activities on weekends. This sudden increase in activity can place excessive stress on the Achilles tendon, particularly when the body is not properly conditioned.

Similarly, sports that involve frequent stopping, starting, jumping, pivoting, or quick changes in direction are particularly high-risk. For example, basketball, soccer, tennis, and pickleball all require repeated forceful contractions of the calf muscles and may lead to sports injury. According to PMC research, sports or recreational activities accounted for 81.9% of Achilles tendon ruptures, with basketball being the most common cause overall.

In addition, ruptures can happen during forceful push-offs, such as sprinting, jumping, or powerfully pointing the foot downward. Although less common, direct trauma can also cause a complete Achilles tear, such as falling from a height.

2. Medication-Induced Weakness

Certain antibiotics can weaken the Achilles tendon, making it more prone to injury. One of the most commonly associated medication groups is fluoroquinolones, including ciprofloxacin and levofloxacin. These antibiotics can affect the structure and strength of fibrous tissue, which increases the risk of inflammation, tears, or complete rupture. This risk can be even greater in older adults, people with previous tendon problems, or individuals taking medications that affect connective tissue. In fact, the NCBI research reported that an elderly man who was being treated with glucocorticoids developed tears in both Achilles tendons just 4 days after starting ciprofloxacin.

Besides that, steroid injections may also contribute to tendon weakening. While these injections are used to reduce pain, swelling, or inflammation, they can damage nearby tendon tissue if injected close to the tendon. As the tendon weakens, it is less able to handle normal stress, increasing the risk of rupture.

3. Underlying Health and Lifestyle Factors

Several health and lifestyle factors can gradually reduce the strength and flexibility of the Achilles tendon. Age is one of the most common risk factors because tendons naturally lose elasticity, strength, and blood supply over time. As blood flow decreases, healing becomes slower, and the tendon becomes more prone to degeneration. For this reason, Achilles tendon ruptures are especially common among adults aged 30 to 50.

Moreover, existing tendon problems, such as untreated Achilles tendinitis or chronic small tears, can further increase the risk because the tendon may already be irritated or weakened before a rupture occurs. Systemic diseases such as gout, rheumatoid arthritis, diabetes, and lupus can also impair tendon health by increasing inflammation, affecting circulation, or weakening connective tissue.

Similarly, obesity can increase the risk, as excess body weight places greater mechanical stress on the heel bone and Achilles tendon during physical activity. Over time, this added load can contribute to high ankle strain, leading to severe pain and, sometimes, a popping sound when a rupture occurs.

How Do Doctors Confirm a Tendon Tear?

Dr. Charles Ruotolo, our orthopedic surgeon, confirms a tendon tear by reviewing medical history and assessing tenderness, swelling, bruising, or a tendon gap. He also uses medical imaging tests, such as ultrasound or magnetic resonance imaging (MRI), to identify avulsion/ stress fractures or soft-tissue joint abnormalities.

These results help him decide whether rest, bracing, targeted exercises, injections, or surgery is the best treatment option. Besides that, he may perform a physical examination to compare the injured side with the healthy side and assess weakness, limited motion, deformity, or loss of function. In addition, he may perform the Thompson test, which involves squeezing the calf to check whether the foot and ankle move normally.

On the other hand, in complex cases, Dr. Charles Ruotolo may use a blood pressure cuff test to measure muscle contraction force. He may also perform an arthrocentesis, during which he draws a sample of joint fluid with a needle to rule out other conditions such as infection or severe inflammation.

Is a Walking Boot Enough for an Achilles Tendon Rupture?

Yes, for most patients, a specialized walking boot is sufficient to heal an Achilles tendon rupture without surgery. This functional bracing holds the foot in a protected position, bringing the torn tendon ends closer together and providing the stability needed for them to reconnect and heal.

To achieve this position, you should use boots with heel wedges that keep your foot in a “tiptoe” position, preventing the ruptured tendon from stretching further. Over 6–12 weeks, your doctor will progressively remove these wedges to flatten the foot while safely managing the range of motion. Many patients may also use a moldable brace, which offers vacuum cushions and adjustable ankle angles to provide a custom-molded fit. However, in cases of complete tears or delayed diagnosis, Achilles tendon surgery may be needed to reduce the risk of re-rupture.

Can Platelet-Rich Plasma Help Tendon Healing?

Yes, platelet-Rich Plasma (PRP) can enhance tendon healing by delivering concentrated growth factors directly to the injury site. This promotes tissue repair, reduces inflammation, and accelerates recovery. PRP injections may also improve tendon strength and function, especially in chronic or degenerative tendon injuries.

In fact, a PMC review reported that PRP stimulates tenocyte and tendon stem/progenitor cell proliferation and collagen production, which accelerate early tendon healing. It also modulates inflammation by downregulating pro‑inflammatory cells and promoting fibroblast anabolic activity. During this therapy, doctors draw a patient’s blood, concentrate the platelets, and inject them into damaged tendons. However, the effectiveness of this treatment may vary based on the following factors:

1. Tendon Type: Tendons with poor blood supply, such as the Achilles, often heal slowly. In such cases, PRP may offer better results by delivering growth factors to promote repair.
2. Injury Severity: Mild or moderate tendon damage may respond better to PRP than severe tears. In cases of severe injuries, doctors may combine PRP with bracing or surgical treatment.
3. Treatment Frequency: Some patients improve after one PRP injection, while others may need multiple sessions. The ideal frequency depends on the tendon condition and healing response.

How Can Bracing Support Achilles Tendon Recovery?

Bracing helps limit painful ankle motion, reduces strain on the tendon, and helps maintain proper foot alignment for Achilles tendon recovery. It can also improve stability, help prevent overstretching, and facilitate a gradual return to walking or activity when used under medical guidance and with targeted exercises.

Depending on your phase of healing and injury stage, you can choose the following bracing options:

Compression Sleeves

Compression sleeves provide gentle, consistent pressure around the ankle and lower leg to help manage swelling and improve circulation. They can reduce discomfort during daily activities, enhance body awareness, and offer light support without restricting movement. Besides that, these sleeves are often recommended during the early recovery phase or for ongoing tendon management.

Heel Lifts

Insert heel lifts into your shoes to slightly raise the heel, reducing stretch and tension on the Achilles tendon while walking and standing. By reducing tendon loading, heel lifts can help relieve pain, support healing, and improve comfort throughout the recovery process. They are commonly used in the acute and subacute stages of Achilles tendon injuries.

Night Splints

You can wear night splints to keep the foot in a neutral or slightly dorsiflexed position while sleeping. It helps prevent the Achilles tendon and calf muscles from tightening overnight. As a result, this can reduce morning stiffness, improve flexibility, and support long-term tendon recovery. Night splints are particularly beneficial if you’re experiencing persistent tightness or discomfort after periods of rest.

When Is Surgery Recommended for a Torn Achilles Tendon?

Our orthopedic surgeon, Dr. Charles Ruotolo, recommends surgery when the gap between the torn tendon ends exceeds 10 mm. He also considers surgery when the RICE method fails to manage a ruptured Achilles tendon, or when your previous doctor diagnosed the injury after 2–3 weeks.

Moreover, Dr. Charles Ruotolo may advise an operative approach for athletes, heavy laborers, and those who need maximum push-off strength and ankle function. He usually performs surgery within 1 to 2 weeks of the injury, before the tendon retracts too much. However, if you have the following conditions, he may not recommend surgery:

• Poor circulation in the legs.
• Patients with uncontrolled diabetes, vascular disease, or neuropathy.
• Smokes heavily, as this significantly increases the risk of wound-healing complications.
• Elderly patients or those who have a relatively sedentary lifestyle

Which Surgical Methods Are Used to Repair a Tendon Tear?

Dr. Charles Ruotolo, our orthopedic sports surgeon, repairs tendon tears using direct tendon repair, tendon grafting, and tendon transfer. To choose the best method, he evaluates imaging results, patient activity levels, the extent of tendon damage, and the condition of the surrounding tissue.

Here’s how he performs these outpatient surgical approaches to repair the damaged Achilles tendon:

Direct Tendon Repair

Dr. Charles Ruotolo prefers direct tendon repair for acute Achilles tendon tears when tissue quality is adequate. He carefully aligns the torn ends of the tendon and sutures them together using specialized, high-strength techniques. This method preserves the native tendon structure and typically allows for a quicker recovery.

Tendon Grafting

Our surgeon performs tendon grafting when direct repair cannot close a tendon gap or when tendon quality is compromised. In this procedure, Dr. Charles Ruotolo harvests a graft either autologous (from the patient’s own tissue) or allogenic (donor tissue) to bridge the defect. After that, he carefully anchors the graft to the healthy tendon ends and surrounding tissue, restoring continuity and strength. Before performing the procedure, he may also use imaging studies and intraoperative assessment to select the appropriate graft type and size to achieve the best functional recovery.

Tendon Transfer

Dr. Charles Ruotolo uses tendon transfer to restore function in chronic tears or when the original tendon is irreparably damaged. He may also consider the patient’s activity demands and the donor tendon’s function before surgery to ensure the transfer supports long-term mobility and reduces the risk of rerupture.

During this method, he re-routes a neighboring tendon, such as the flexor hallucis longus, to take over the function of the damaged Achilles. This procedure not only restores plantarflexion strength but also maintains ankle stability. If you are experiencing ongoing pain or weakness due to a chronic Achilles tendon injury, reach out today for effective treatment options.

What Is the Success Rate of Achilles Tendon Repair?

Surgical repair of the Achilles tendon had a much lower rerupture rate (~1.9%) than nonsurgical treatment (~8.1%), according to an NIH study. Another PMC cohort study of 423 patients reported a 1% rerupture rate and low infection risk after operative repair.

Additionally, an NCBI review reported that operative treatment of Achilles tendon rupture resulted in a significantly lower rerupture rate of 3.5% compared with 12.6% in patients treated non-operatively. Researchers also found that in Achilles tendon ruptures treated with 8 weeks of casting and immediate postoperative weightbearing, the re-rupture rate was 7%.

How Long Does an Achilles Tendon Tear Take to Heal?

A torn Achilles tendon can take about 4 to 6 months to heal for basic daily activities. However, full recovery may take 6 to 12 months for athletes. Most individuals return to their previous activity level within 18 to 24 months after an Achilles tendon rupture.

During the initial phase of immobilization (weeks 0–6), a cast or walking boot holds your foot in a downward-pointed position. In some cases, immobilization may last for 6 to 10 weeks to allow the tendon to heal. Moreover, most patients have to wear a boot for 6 weeks post-injury. In weeks 6–12, you can perform weight-bearing exercises like double-leg calf raises. However, after 3-6 months, you can walk normally, but the calf muscle on the affected leg will still be weaker. Over the next 6-12 months, your tendon scar continues to remodel, mature, and regain tensile strength.

What Follow-Up Care Is Needed After Surgery?

After Achilles tendon surgery, you should attend regular follow-up visits, monitor your wound, and change your bandages as directed by our medical team. If your stitches are non-dissolvable, you must remove them after 1 to 2 weeks

Furthermore, you must follow your doctor’s medication schedule for pain relief. You should also avoid taking over-the-counter blood thinners (like aspirin) unless specifically approved by your surgeon. During this time, your body needs extra protein, vitamins, and minerals to repair itself. Therefore, you should take lean meats, fish, vegetables, and whole grains. You must drink plenty of water throughout the day to prevent dehydration and constipation.

Along with these precautions, gradually increasing your walking helps prevent blood clots and lowers the risk of chest infections. However, you should not lift anything heavier than 10 lbs (about 4.5 kg) unless your doctor permits it. Furthermore, you should wear a protective boot or brace for several weeks while gradually increasing weight-bearing activities.

What Are the Risks of Delaying Treatment?

Delaying treatment for an Achilles tendon rupture (typically beyond 4 weeks) allows the torn tendon to retract, shrink, and scar. Surgeons treat this “chronic” rupture with more complex, invasive surgery, and it often causes permanent calf muscle weakness, a persistent limp, and an altered gait.

Over time, the ruptured ends of the tendon pull further apart and degenerate. Even if it heals on its own, it will heal at an elongated length, which reduces your ability to generate force. Additionally, if you delay surgical intervention, surgeons may need to perform complex reconstructions. These procedures may involve using donated tissue (allografts) or transferring other tendons.
