What Is Achilles Tendinopathy?
The Achilles tendon is the largest tendon in the human body. It connects the gastrocnemius and soleus muscles of the calf to the calcaneus, or heel bone, and plays a critical role in transmitting force during walking, running and jumping.
Achilles tendinopathy refers to a condition in which the tendon becomes painful and less tolerant of mechanical loading. Changes may occur within the tendon structure, including alterations in collagen organisation and tendon thickness.
Achilles tendinopathy is commonly classified according to where the symptoms originate:
- Mid-portion Achilles tendinopathy: Symptoms are typically located several centimetres above the heel bone.
- Insertional Achilles tendinopathy: Symptoms occur where the Achilles tendon attaches to the heel bone.
The condition is generally load-related, meaning symptoms often increase when the tendon is required to handle greater physical demands.
Achilles tendinopathy is not simply "inflammation of the tendon." While inflammatory processes may play a role during some stages, persistent symptoms are more accurately understood as an interaction between tendon structure, pain sensitivity and the tendon’s capacity to tolerate load.
A tendon can also show structural abnormalities without causing pain. Therefore, imaging findings such as tendon thickening or changes on ultrasound or MRI need to be interpreted alongside symptoms and clinical findings.
What Causes Achilles Tendinopathy?
Achilles tendinopathy usually develops when the mechanical demands placed on the tendon exceed its current capacity to tolerate and adapt to those demands. Common contributing factors include:
- Sudden increase in running: Increasing running distance, speed, hills or frequency too quickly can substantially increase Achilles tendon loading.
- Return to sport after inactivity: Restarting running or jumping activities after a prolonged break can place demands on a tendon that has temporarily lost conditioning.
- Changes in training: Altering footwear, running surfaces, training intensity or exercise selection can change the load experienced by the tendon.
- Repetitive jumping or sprinting: Sports involving repeated explosive movements place significant demands on the Achilles tendon.
- Reduced calf strength: Lower calf muscle capacity may reduce the ability of the lower limb to manage demanding activities.
- Age-related changes: Tendon structure and its ability to adapt to loading can change with age.
- Higher body weight: Increased body mass can increase the forces transmitted through the Achilles tendon during weight-bearing activity.
- Previous Achilles problems: Previous symptoms may affect the tendon’s current load tolerance.
Achilles tendinopathy is rarely caused by a single factor. It is more useful to consider the relationship between training load, tendon capacity, strength, recovery and individual characteristics.
Importantly, physical activity does not inherently damage the Achilles tendon. Appropriate progressive loading is actually an essential part of helping the tendon adapt and become more capable.
Common Signs & Symptoms
Achilles tendinopathy typically produces pain and stiffness around the back of the ankle or heel. Common symptoms include:
- Pain in the Achilles tendon
- Morning stiffness around the Achilles or heel
- Pain during walking or running
- Discomfort when climbing stairs
- Pain during jumping or sprinting
- Tenderness along the tendon
- Stiffness after periods of inactivity
- Pain that increases with higher levels of physical activity
- Reduced calf strength or endurance
- Difficulty performing repeated heel raises
- Reduced running or sporting capacity
In many cases, symptoms are particularly noticeable at the beginning of activity or after periods of rest, and may change as activity continues.
Symptoms can also increase after exercise or the following morning, making the tendon’s response over the next 24 hours useful when determining appropriate loading.
Trivayu's Approach
At Trivayu, we focus on restoring the Achilles tendon’s capacity rather than simply chasing pain reduction.
An Achilles tendon that feels better but has not regained sufficient strength and load tolerance may struggle when you return to running, jumping or sport. Our rehabilitation therefore considers both your current symptoms and the demands you ultimately want to place on the tendon.
Your assessment considers:
- How your symptoms developed
- Current pain and stiffness
- Achilles and calf strength
- Ankle movement
- Single-leg function
- Recent changes in training or activity
- Running and sporting demands
- Previous injuries
- Your individual recovery goals
Your programme is then progressively developed according to your current capacity.
Early rehabilitation may focus on managing symptoms and establishing an appropriate level of tendon loading. As capacity improves, treatment progresses towards heavier strengthening, single-leg loading, dynamic exercises, running and sport-specific activities.
For athletes, the final stages may include sprinting, jumping, acceleration, deceleration and repeated high-intensity movements.
For non-athletes, rehabilitation can instead focus on walking, stairs, recreational activities and the physical demands of everyday life.
Our goal is to help you return not just to pain-free daily activity, but to a level of tendon strength and capacity that supports the life you want to lead.

FAQs
Should I see a physiotherapist for Achilles tendinopathy?
Yes. If Achilles pain persists, affects walking, running or daily activity, a physiotherapist can assess tendon loading and guide a progressive rehabilitation plan.
What is the best treatment for Achilles tendinopathy?
Treatment usually focuses on load management and progressive calf strengthening, combined with activity modification and physiotherapy. Complete rest is usually not the long-term solution.
Can Achilles tendinopathy heal without surgery?
Yes. Most cases improve with conservative treatment such as progressive exercise, load management and physiotherapy. Surgery is generally reserved for persistent cases that do not respond to rehabilitation.
What exercises are good for Achilles tendinopathy?
Progressive calf raises and other tendon-loading exercises are commonly used to improve strength and tendon capacity. Exercises should be adjusted according to pain and activity tolerance.
How long does Achilles tendinopathy take to recover?
Recovery often takes several weeks to several months, depending on symptom duration and severity. Tendons usually require gradual, consistent loading over time.
When can I return to running after Achilles tendinopathy?
Return to running should begin when walking, calf strengthening and hopping are comfortable and well tolerated. Running volume should then be increased gradually.
