What Is Short Achilles Tendon?

Written by Medicover Team and Medically Reviewed by Dr P Venkata Sudhakar , Orthopedics

The Achilles tendon, the largest and strongest tendon in the human body, connects the calf muscles to the heel bone. Its primary function is to facilitate movements such as walking, running, and jumping by transmitting the force generated by the calf muscles to the foot.

However, when the Achilles tendon is shorter than normal, it can lead to a range of complications that can significantly affect an individual's mobility and quality of life.

What are the Short Achilles Tendon Symptoms and Warning Signs?

The symptoms of a short Achilles tendon can vary depending on the severity of the condition. Common symptoms include:

Limited Range of Motion

A shortened Achilles tendon restricts the foot's ability to move freely, leading to a limited range of motion.
This limitation can affect activities such as walking, running, and climbing stairs.

Heel Pain

Individuals with a short Achilles tendon often experience pain in the heel, particularly during activities that require the tendon to stretch.
The pain can be sharp or throbbing and may worsen with prolonged activity.

Toe Walking

Children with a short Achilles tendon may exhibit toe walking, a condition where they walk on their toes instead of their heels.
This gait abnormality occurs because the shortened tendon prevents the heel from making contact with the ground.

Muscle Fatigue

The calf muscles may become fatigued more quickly due to the increased tension on the short Achilles tendon.
This fatigue can lead to discomfort and reduced endurance during physical activities.

What are the Common Causes and Risk Factors of Short Achilles Tendon?

A short Achilles tendon can be congenital or acquired. Congenital cases are often due to genetic factors that affect the development of the musculoskeletal system. In contrast, acquired cases can result from various factors, including:

Genetic Predisposition

Individuals with a family history of musculoskeletal abnormalities are more likely to have a short Achilles tendon.
Genetic mutations affecting the development and elasticity of connective tissues can contribute to this condition.

Muscle Imbalance

A disproportionate strength between the calf muscles and other muscle groups can lead to a shortened Achilles tendon.
For example, overdeveloped calf muscles can exert excessive tension on the tendon, causing it to shorten over time.

Inadequate Stretching

Lack of proper stretching before and after physical activities can contribute to the development of a short Achilles tendon.
Regular stretching helps maintain the tendons' length and elasticity, preventing them from becoming shortened or stiff.

Trauma or Injury

Injuries such as tears or ruptures of the Achilles tendon can lead to scar tissue formation, which may shorten the tendon.
Additionally, immobilization of the foot and ankle during the healing process can contribute to tendon shortening.

How is Short Achilles Tendon Diagnosed?

Diagnosing a short Achilles tendon involves a complete evaluation by a healthcare professional. The diagnostic process typically includes:

Medical History

A thorough medical history helps identify any genetic predispositions, previous injuries, or other factors contributing to the condition.
The healthcare provider will inquire about symptoms, their onset, and any activities that exacerbate the symptoms.

Physical Examination

A physical examination assesses the range of motion, flexibility, and strength of the foot and ankle.
The healthcare provider observes the patient's gait and looks for signs of toe walking or other abnormalities.

Imaging Studies

Imaging studies such as X-rays, ultrasound, or MRI may be used to visualize the Achilles tendon and assess its length and condition. These imaging techniques can also identify any structural abnormalities or scar tissue that may be contributing to the shortening.

What are the Treatment Options for Short Achilles Tendon?

The treatment of a short Achilles tendon aims to alleviate symptoms, restore normal function, and prevent further complications. Treatment options include:

Stretching Exercises

Regular stretching exercises can help lengthen the Achilles tendon and improve flexibility.
These exercises should be performed under the guidance of a physical therapist to ensure proper technique and effectiveness.

Orthotic Devices

Orthotic devices such as heel lifts or custom insoles can help reduce strain on the Achilles tendon and alleviate pain.
These devices can also improve gait and prevent further shortening of the tendon.

Physical Therapy

Physical therapy involves a combination of stretching, strengthening, and functional exercises to improve the range of motion and overall function of the foot and ankle.
Physical therapists may also use modalities such as ultrasound or electrical stimulation to reduce pain and inflammation.

Gastrocnemius Recession

Gastrocnemius recession is a surgical procedure that involves lengthening the calf muscle to reduce tension on the Achilles tendon.
This procedure can improve the range of motion and alleviate symptoms.

Achilles Tendon Lengthening

Achilles tendon lengthening is a surgical procedure that involves making small incisions in the tendon to allow it to stretch and lengthen.
This procedure is typically performed in severe cases where other treatments have failed.

Tendon Transfer

Tendon transfer involves repositioning a nearby tendon to take over the function of the shortened Achilles tendon. This procedure can improve function and reduce pain.

Post-Treatment Rehabilitation

Rehabilitation is a crucial component of the treatment process, regardless of whether surgical or non-surgical methods are used. Post-treatment rehabilitation focuses on restoring strength, flexibility, and function to the foot and ankle.

Gradual Return to Activity

Patients should gradually return to their normal activities to avoid overloading the Achilles tendon.
A physical therapist can provide guidance on the appropriate progression of activity levels.

Strengthening Exercises

Strengthening exercises targeting the calf muscles and surrounding muscle groups can help support the Achilles tendon and prevent future complications. These exercises should be performed regularly to maintain strength and function.

Monitoring and Follow-Up

Regular follow-up appointments with a healthcare provider are essential to monitor progress and address any issues that may arise during the rehabilitation process.
Ongoing monitoring ensures that the treatment plan remains effective and adjustments can be made as needed.

When to See a Doctor?

You should consult a healthcare professional if you experience any of the following symptoms, as they may indicate a short Achilles tendon or related complications:

Persistent heel pain, especially during or after physical activity
Limited ability to flex or move your foot and ankle normally
A noticeable change in your walking pattern, such as toe walking
Recurrent calf muscle fatigue or cramping
Difficulty performing everyday movements like climbing stairs or standing flat-footed

Early medical evaluation can help prevent further tendon shortening, alleviate discomfort, and improve long-term mobility and function.
