What Is Achilles Tendinitis — and When Does It Become a Rupture?

The Achilles tendon is the thickest and strongest tendon in the human body, connecting the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus). It transmits enormous forces — up to 8 times your body weight during running — making it both essential for movement and uniquely vulnerable to overuse and acute injury.

Achilles tendinitis (also spelled tendonitis, and increasingly called tendinopathy in clinical literature) refers to inflammation and degenerative changes within the tendon tissue. It exists on a spectrum: early-stage reactive tendinopathy involves cellular swelling with intact structure, while chronic tendinopathy involves disorganized collagen, neovascularization, and significantly weakened tissue.

A tendon rupture — either partial or complete — occurs when that weakened or suddenly overloaded tendon tears. Complete ruptures typically happen 2–6 cm above the heel bone insertion, a zone of relatively poor blood supply known as the “critical zone.” This is not always preceded by diagnosed tendinitis; roughly one-third of ruptures occur in people with no prior tendon symptoms.

Longer, more structured rehabilitation

Clinical Note

Modern sports medicine prefers the term tendinopathy over tendinitis because histological studies consistently show minimal inflammatory cells in chronic cases — the primary pathology is degenerative, not inflammatory. This distinction matters for treatment: anti-inflammatory drugs address only part of the picture.

Causes & Risk Factors

Achilles tendon injuries rarely have a single cause. They typically result from a combination of intrinsic (body-related) and extrinsic (environment/load-related) factors converging over time — or in the case of rupture, a single catastrophic overload event on tissue that may already be compromised.

⚡ Sudden Training Load Increases — the most common trigger

Adding more than 10% weekly mileage, jumping into sprint training, or returning to sport after a break without adequate reconditioning are classic precursors. The Achilles adapts slowly — collagen remodeling takes weeks — and the tendon cannot keep pace with rapid demands placed on it. This is especially common in recreational runners who ramp up training for a race.

🥾 Footwear link: Switching abruptly from a cushioned heel-drop shoe to a minimalist or zero-drop shoe dramatically increases Achilles load. Transition should take 8–12 weeks minimum.

🦵 Calf Muscle Weakness & Tightness — biomechanical driver

The gastrocnemius and soleus must absorb and generate force through the Achilles with every step. When these muscles are weak, inflexible, or fatigued, the tendon absorbs disproportionate stress. Tight calves in particular reduce ankle dorsiflexion range, forcing compensatory mechanics that overload the tendon’s insertion and mid-portion.

🥾 Footwear link: Shoes with elevated heels (8–12mm drop) shorten the calf over time. When athletes switch to flatter shoes without stretching protocol, sudden tendon lengthening under load can trigger injury.

🏃 Overpronation & Poor Foot Mechanics — structural factor

Excessive inward rolling of the foot during the stance phase of gait causes the Achilles to whip medially with each stride, creating a “bowstring” effect that generates torsional stress the tendon is not designed to handle. Flat feet (pes planus) and high arches (pes cavus) both alter load distribution through the Achilles in different ways.

🥾 Footwear link: Motion-control or stability shoes can reduce overpronation. Custom orthotics may be warranted for significant structural deformity.

💊 Fluoroquinolone Antibiotics & Systemic Factors — often overlooked

Fluoroquinolone antibiotics (ciprofloxacin, levofloxacin) carry an FDA black-box warning for tendon rupture risk — the Achilles is most commonly affected. The mechanism involves disruption of tenocyte metabolism and collagen synthesis. Risk is amplified in patients over 60, those on corticosteroids, and kidney transplant recipients. Ruptures can occur during treatment or up to several months after completing the course.

Other systemic risk factors include: type 2 diabetes (impairs tendon healing), rheumatoid arthritis, gout, obesity (BMI >30 increases risk 3-fold), and corticosteroid injections directly into the tendon.

🎯 The “Weekend Warrior” Pattern — rupture-specific risk

Complete Achilles ruptures disproportionately affect sedentary or semi-active adults (30–50 years) who engage in explosive activity — basketball, squash, tennis, or recreational soccer — without adequate conditioning. The combination of age-related tendon stiffness, subclinical degeneration, and sudden eccentric loading (landing, pivoting, pushing off) is a classic rupture scenario. The tendon may feel fine until it doesn’t.

Symptoms: Tendinitis vs. Partial Tear vs. Full Rupture

Recognizing where on the injury spectrum you fall is critical — the treatments differ substantially, and misidentifying a rupture as a sprain or strain is a common and costly mistake. Here is a clear breakdown of what each stage typically feels like.

Achilles Tendinitis / Tendinopathy

Morning stiffness: The hallmark symptom — pain and stiffness at the back of the heel or 2–6 cm above it that is worst with the first steps after rest and improves with gentle activity
Activity-related pain: Discomfort that starts after a run, or begins during a run and forces you to slow down; eases with warm-up in early stages but persists throughout activity in later stages
Localized tenderness: Pain when pinching the tendon between thumb and forefinger, particularly at the mid-tendon or at the heel bone insertion
Thickening or nodule: A palpable fusiform swelling or hard nodule within the tendon body, indicating chronic degenerative change
Crepitus: A creaking sensation when moving the ankle, caused by paratenon inflammation

Partial Tendon Tear

Sudden sharp pain during activity, often described as being “kicked in the back of the leg”
Swelling and bruising around the tendon within hours
Reduced but preserved push-off strength — you can still walk, but with a limp
Significant tenderness at the tear site; may feel a slight depression in the tendon

Complete Achilles Rupture — Warning Signs

Audible “pop” or snap — often heard by bystanders, followed by immediate severe pain and inability to continue activity

Inability to stand on tiptoe on the affected leg — a key clinical indicator of complete rupture versus severe tendinitis

Palpable gap in the tendon — a hollow or depression 2–6 cm above the heel that can be felt through the skin

Positive Thompson test: When the calf is squeezed with the patient prone, the foot does not plantarflex — this test has ~96% sensitivity for complete rupture

Paradoxical reduced pain after rupture — some patients report that pain actually decreases after the snap, leading them to underestimate the severity of the injury

Seek Emergency Care Immediately If

You heard or felt a pop in the back of your leg during activity, you cannot bear weight or push off on your toes, and you have a visible swelling or depression above the heel. A complete rupture is a time-sensitive injury — surgical outcomes are significantly better when addressed within 2 weeks of injury.

Diagnosis: How Doctors Confirm the Injury

Accurate diagnosis determines the entire treatment pathway. Most Achilles injuries can be diagnosed clinically, but imaging plays an important role in grading severity, ruling out bony pathology, and surgical planning.

Clinical Examination

An experienced orthopedic surgeon or sports medicine physician will perform several physical tests. The Thompson (Simmonds) test is the gold standard for rupture detection — the patient lies prone with feet hanging off the table, and the examiner squeezes the calf muscle. Normal plantarflexion response rules out complete rupture. The Royal London Hospital test and arc sign help localize mid-tendon pathology. Palpation along the tendon identifies the site of maximum tenderness, thickening, or a gap.

Imaging Modalities

Imaging Type	Best Used For	Limitations
Ultrasound (US)	First-line for tendinopathy; dynamic assessment of tendon integrity; guiding injections; real-time evaluation of partial tears	Operator-dependent; limited for deep structures; less detail than MRI
MRI	Gold standard for grading partial tears; surgical planning; assessing tendon retraction after rupture; differentiating tendinopathy from paratendinopathy	Expensive; not always available urgently; overestimates pathology in asymptomatic tendons
X-Ray	Ruling out calcaneal avulsion fracture, heel spurs (Haglund deformity), or calcific deposits within the tendon	Cannot visualize soft tissue tendon pathology directly
CT Scan	Bony detail in complex insertional pathology; pre-surgical planning for Haglund resection	Radiation exposure; poor soft tissue contrast for tendon itself

Diagnostic Insight

Ultrasound is increasingly the preferred first-line imaging tool in sports medicine clinics because it is real-time, inexpensive, and can be performed in-office. A skilled sonographer can identify tendon thickening, hypoechoic areas of degeneration, neovascularization on Doppler, and partial tears with high accuracy — often making MRI unnecessary for initial management decisions.

Differentiating Insertional vs. Non-Insertional Tendinopathy

This distinction is clinically important because treatments differ. Non-insertional tendinopathy (mid-portion) affects the tendon 2–7 cm above the heel and responds well to eccentric exercise programs. Insertional tendinopathy involves the tendon at or within 2 cm of the calcaneal attachment, is often associated with a Haglund deformity (bony prominence), and is more resistant to eccentric loading — which can actually worsen it. Insertional cases often require modified rehabilitation and may need surgical intervention sooner.

Treatment Options: Conservative to Surgical

Treatment decisions depend on injury type (tendinopathy vs. partial vs. complete rupture), patient age and activity level, symptom duration, and imaging findings. The good news: the majority of tendinopathy cases resolve with structured conservative management over 3–6 months.

Conservative Treatment for Tendinopathy

Load Management — Reduce, Don’t Eliminate

Complete rest is counterproductive. Tendons need mechanical load to stimulate collagen synthesis. Reduce high-impact activity by 50–70% and substitute low-load alternatives (cycling, swimming) while maintaining tendon stimulus through structured exercise.

Eccentric Calf Raises — The Alfredson Protocol

The Alfredson eccentric program (3 sets × 15 reps, twice daily, 7 days/week, 12 weeks) remains one of the most evidence-supported interventions for mid-portion Achilles tendinopathy, with success rates of 60–90% in multiple trials. Exercises are performed with the knee straight (gastrocnemius) and bent (soleus), lowering the heel slowly over a step edge.

Heavy Slow Resistance (HSR) Training

For patients who cannot tolerate the pain of eccentric loading, HSR — slow concentric and eccentric calf raises with added weight (3 sets × 15 reps, progressing to 4 × 6 at heavier loads) — shows equivalent or superior outcomes to the Alfredson protocol in recent RCTs and is better tolerated.

Heel Lifts & Footwear Modification

A 12–15 mm heel lift reduces Achilles tendon strain by shortening the calf-tendon unit. This is a low-cost, immediate pain-reduction strategy. Transitioning to supportive footwear with an appropriate heel-to-toe drop (8–10 mm) during the acute phase is also recommended.

Adjunct Therapies: PRP, Shockwave, Nitroglycerin

Extracorporeal shockwave therapy (ESWT) has the strongest adjunct evidence — particularly for chronic cases (>3 months) that have failed exercise therapy. Platelet-rich plasma (PRP) injections show promise in ultrasound-guided delivery but evidence remains mixed. Topical nitroglycerin patches (0.2 mg/hour) have shown benefit in some RCTs, though side effects (headache) limit compliance.

“The single most important principle in Achilles tendinopathy management is progressive tendon loading — not rest, not passive therapy. The tendon must be mechanically stimulated to remodel.”

Treatment for Complete Achilles Rupture: Surgery vs. Non-Surgical

This is one of the most debated topics in orthopedic surgery. Both approaches can achieve excellent outcomes when protocols are followed rigorously.

Surgical Repair

Lower re-rupture rate (~3–5% vs. 8–12% non-surgical)
Faster return to high-level sport
Preferred for younger, active patients and athletes
Risks: wound infection, sural nerve damage, DVT, scarring
Minimally invasive techniques reducing complication rates

Functional Non-Surgical

Equivalent functional outcomes at 1–2 years in most studies
No surgical risks; suitable for older, less active patients
Requires strict early functional bracing protocol (not cast immobilization)
Higher re-rupture rate if protocol not followed
Increasingly preferred in patients over 60 with comorbidities

Key Insight: The Protocol Matters More Than the Approach

A landmark 2019 meta-analysis in JAMA Surgery found that non-surgical functional rehabilitation with early weight-bearing achieved outcomes comparable to surgery — but only when patients followed a structured early-motion protocol. Prolonged cast immobilization in non-surgical cases significantly worsens outcomes. If you choose non-surgical treatment, ensure your team uses an accelerated functional protocol.

Footwear’s Role: Shoes That Help or Hurt Your Achilles

Footwear is one of the most modifiable risk factors in Achilles tendon health — yet it is frequently underestimated. The wrong shoes can initiate injury, perpetuate chronic tendinopathy, and slow recovery. The right shoes, combined with appropriate transition protocols, can meaningfully reduce tendon load and support healing.

📐

Heel-to-Toe Drop

Drop (the height difference between heel and forefoot) directly affects Achilles tendon length and load. A higher drop (10–12 mm) reduces tendon elongation during each stride, decreasing stress on an irritated tendon. Zero-drop or minimalist shoes maximally lengthen the Achilles — beneficial for healthy tendons but hazardous during flares.

✅ During tendinopathy: choose 8–12 mm drop. Transition to lower-drop shoes only after full resolution, over 8–12 weeks.

🛡️

Heel Counter Rigidity

A firm heel counter stabilizes the calcaneus and reduces excessive heel motion (pronation/supination) that creates torsional stress on the Achilles. Shoes with soft or collapsed heel counters allow the heel to wobble, amplifying tendon strain with every step.

✅ Press on the heel counter — it should resist compression. Replace running shoes every 400–500 miles when cushioning and structure degrade.

🌊

Midsole Cushioning & Energy Return

Adequate midsole cushioning attenuates impact forces that travel up through the heel into the Achilles. However, excessively soft midsoles (e.g., maximalist foam) can reduce proprioceptive feedback and destabilize the ankle, indirectly increasing tendon load through compensatory mechanics.

✅ Moderate, responsive cushioning (not ultra-plush) is optimal. Look for EVA or PEBA foam with good rebound, not just soft compression.

🔧

Achilles Notch / Heel Tab Design

Shoes with a rigid, high heel tab that digs into the back of the ankle can directly irritate the Achilles tendon insertion and the retrocalcaneal bursa. This is a common and underappreciated cause of insertional Achilles pain — particularly in cycling shoes, dress shoes, and some running shoes with aggressive heel collars.

✅ Look for shoes with a soft, notched, or lowered heel collar. Brands like Hoka, Brooks, and ASICS offer models with Achilles-friendly heel designs specifically noted in their product specs.

🦶

Arch Support & Stability Features

Overpronation increases torsional load on the Achilles by up to 40% in biomechanical studies. Stability shoes with medial post support or motion-control features reduce this whipping motion. However, excessive correction can shift stress elsewhere — the goal is neutral, not overcorrected, alignment.

✅ Gait analysis at a specialty running store is worthwhile. Pair with custom orthotics if structural deformity (flat feet, high arches) is contributing to symptoms.

The Minimalist Shoe Transition Warning

Studies tracking runners switching to minimalist or barefoot-style footwear document a significant spike in Achilles tendon injuries during the transition period — often in the first 4–8 weeks. If you want to run in lower-drop shoes, reduce your weekly mileage by 50% on transition, add eccentric calf strengthening, and increase drop reduction by no more than 2–4 mm every 4 weeks.

Recovery Timeline & Rehabilitation

Recovery from Achilles injuries is notoriously slow — tendons have poor blood supply and collagen remodeling is a months-long process. Setting realistic expectations prevents premature return to activity, which is the most common cause of re-injury.

Tendinopathy Recovery Timeline

Phase	Timeframe	Goals & Activities
Acute / Reactive	Weeks 1–4	Reduce load, manage pain, begin isometric calf exercises (5 × 45-second holds), heel lifts, footwear modification
Tendon Loading	Weeks 4–12	Begin Alfredson eccentric protocol or HSR; cross-training (cycling, swimming); gradual return to walking
Return to Running	Weeks 10–20	Structured run-walk intervals; pain monitoring (≤4/10 acceptable during, must resolve within 24 hours); mileage progression at 10% per week
Full Sport Return	Months 4–6+	Sport-specific drills, plyometrics, change-of-direction work; single-leg calf raise endurance test (≥25 reps pain-free)

Post-Rupture Rehabilitation (Surgical & Non-Surgical)

Weeks 0–2: Protective Phase

Non-weight-bearing in a boot or cast with foot plantarflexed (20–30°). Post-surgical wound care. Gentle range-of-motion exercises within the brace if protocol allows. DVT prophylaxis considered in high-risk patients.

Weeks 2–6: Early Weight-Bearing

Progressive weight-bearing in a walking boot with heel wedges. Begin active plantarflexion and dorsiflexion within pain-free range. Pool walking and cycling with low resistance. Swelling management with compression and elevation.

Weeks 6–12: Strengthening Phase

Transition out of boot to supportive footwear (10–12 mm heel drop recommended). Begin bilateral calf raises, progressing to single-leg. Balance and proprioception training. Stationary cycling and swimming. Scar tissue management if surgical.

Months 3–6: Functional Restoration

Progressive loading with resistance. Begin jogging on flat surfaces. Introduce sport-specific movements. Criteria-based progression — not time-based. Calf strength should reach ≥90% of the unaffected side before running.

Months 6–12: Return to Sport

Plyometric progression (double-leg hopping → single-leg → sport-specific). Return to competitive sport typically at 9–12 months for surgical cases, 10–14 months for non-surgical. Psychological readiness testing recommended — fear of re-injury is a documented barrier to full return.

The 24-Hour Pain Rule

A practical guide used by sports physiotherapists: pain during activity should not exceed 4 out of 10 on a pain scale, and any post-exercise soreness should fully resolve within 24 hours. If pain exceeds these thresholds, reduce load. This rule prevents both underloading (which delays healing) and overloading (which causes setbacks).

Prevention Strategies That Actually Work

Achilles tendon injuries are largely preventable with consistent attention to training principles, strength work, and footwear hygiene. These are the evidence-based strategies with the highest impact.

📈

Follow the 10% Rule for Training Load

Never increase weekly running mileage, intensity, or frequency by more than 10% per week. This applies equally to returning from injury, starting a new training block, or adding speed work. The Achilles tendon’s collagen adaptation lags behind cardiovascular fitness by weeks.

✅ Use a training log or GPS watch app to track weekly load. Build a 3-week loading block followed by a 1-week deload (reduce by 20–30%).

💪

Year-Round Calf Strengthening

The most powerful single prevention strategy. Single-leg calf raises (both straight-knee and bent-knee) performed 3× per week maintain the strength and stiffness of the calf-tendon unit needed to absorb running loads. Aim for ≥25 single-leg calf raises as a maintenance benchmark.

✅ Include eccentric calf lowering (lower over 3–4 seconds) in your routine even when asymptomatic — this is the best tendon conditioning exercise known.

🔄

Rotate Running Shoes

Running in multiple shoe models with different drop heights and cushioning profiles distributes stress across different tissue structures, reducing repetitive loading at any single point. Studies show runners who rotate 2+ shoe models have lower overall injury rates including Achilles issues.

✅ Keep a daily trainer (8–10 mm drop, moderate cushion) and a lighter shoe for faster workouts. Alternate between them throughout the training week.

🌅

Address Morning Stiffness Early

Morning stiffness that persists beyond the first few minutes of walking is an early warning sign of tendinopathy. Addressing it at this stage — with load modification, heel lifts, and targeted exercise — prevents progression to chronic tendinopathy or rupture risk. Do not “run through” persistent morning stiffness.

✅ If morning stiffness lasts more than 10–15 minutes for 3+ consecutive days, see a sports medicine physician or physiotherapist within 2 weeks.

Special Note for “Weekend Warriors”

If you play recreational sports (basketball, tennis, squash, soccer) 1–2 times per week without structured conditioning between sessions, your Achilles tendon is at elevated rupture risk. The solution is not to stop playing — it is to add 2 sessions of calf strengthening per week and ensure you complete a proper warm-up including dynamic calf raises and light jogging before explosive activity.

Common Myths About Achilles Injuries

Misinformation about Achilles tendon injuries is widespread — from gym culture, online forums, and even some outdated clinical guidance. Here are the most important myths to correct.

False “Rest is the best treatment for Achilles tendinopathy.”

Complete rest leads to tendon atrophy and reduced load capacity — making the tendon weaker and more vulnerable when you return to activity. The evidence strongly supports active, graded loading as the primary treatment. Rest is appropriate only in the very acute phase (first 3–7 days) or if pain is severe enough to alter gait.

False “Cortisone injections are a good treatment for Achilles tendinopathy.”

Corticosteroid injections into or around the Achilles tendon are associated with increased risk of tendon rupture and are generally contraindicated by most sports medicine guidelines. While they may provide short-term pain relief, they impair collagen synthesis and weaken tendon structure. They should not be used as a primary treatment for Achilles tendinopathy.

False “If you can walk after an Achilles injury, it’s not a rupture.”

This is a dangerous myth. Many patients with complete Achilles ruptures can walk with a limp because other ankle plantarflexors (flexor hallucis longus, tibialis posterior) partially compensate. The ability to walk does not rule out rupture. The Thompson test and inability to perform a single-leg tiptoe are far more reliable indicators.

Partly True “Surgery always gives better outcomes than non-surgical treatment for Achilles rupture.”

This was the prevailing view until the mid-2010s, when high-quality RCTs showed that functional non-surgical rehabilitation achieves comparable outcomes to surgery at 1–2 years in most patients — with lower complication risk. Surgery remains preferred for young, high-level athletes and cases where gap closure is needed. The key variable is the rehabilitation protocol, not the surgical decision alone.

False “Stretching the Achilles is always beneficial.”

Aggressive static stretching of an already irritated or reactive Achilles tendon can worsen symptoms by increasing compressive load at the insertion — particularly in insertional tendinopathy. Gentle calf flexibility work is appropriate for non-insertional tendinopathy, but aggressive stretching should be avoided during flares. Strengthening through range of motion (eccentric exercises) is more beneficial than passive stretching alone.

False “Minimalist shoes prevent Achilles injuries by strengthening the foot.”

While minimalist shoes can strengthen intrinsic foot muscles over time, the transition period significantly increases Achilles tendon load — and injury rates spike during this window. The long-term benefits are real but require a very gradual, structured transition. Switching abruptly is one of the most reliable ways to develop Achilles tendinopathy.

Frequently Asked Questions

These are the questions most commonly asked by patients, athletes, and caregivers dealing with Achilles tendon injuries in 2026.

❓ How long does Achilles tendinopathy take to heal?

Most cases of mid-portion Achilles tendinopathy resolve with structured loading programs within 3–6 months. However, chronic cases (symptoms lasting more than 6 months before treatment) may take 9–12 months to fully resolve. Insertional tendinopathy tends to be more stubborn. The key predictor of recovery time is how quickly appropriate loading therapy is started — delayed treatment consistently leads to longer recovery.

Approximately 20–30% of patients develop chronic symptoms that persist beyond 12 months, often requiring additional interventions such as shockwave therapy or, in refractory cases, surgical debridement.

❓ Can I run with Achilles tendinopathy?

In many cases, yes — with modification. The key criteria are: pain does not exceed 4/10 during the run, pain does not worsen as the run progresses, and any post-run soreness resolves fully within 24 hours. If these conditions are met, continued running at reduced volume is acceptable and may even support recovery by maintaining tendon load stimulus.

You should stop running if: pain is severe or alters your gait, there is significant swelling after each run, or pain consistently exceeds the 24-hour rule. Always consult a sports physiotherapist for a personalized return-to-run plan.

❓ What is the re-rupture rate after Achilles tendon repair?

Re-rupture rates after surgical repair are approximately 3–5%, compared to 8–12% with non-surgical functional rehabilitation. However, these rates converge significantly when non-surgical patients follow a strict early weight-bearing protocol — some recent studies show re-rupture rates as low as 3–4% with optimized non-surgical management. Return to the same sport is achieved by approximately 80–85% of patients at 12 months regardless of treatment approach.

❓ Does PRP injection work for Achilles tendinopathy?

The evidence for PRP (platelet-rich plasma) in Achilles tendinopathy is mixed. Several high-quality RCTs, including the TOPAZ trial, found no significant benefit over placebo injection at 12 months. However, some studies show short-term pain reduction and potential benefit in specific populations (chronic cases with neovascularization on Doppler ultrasound). Current consensus is that PRP should be considered a second-line adjunct after failure of structured exercise therapy — not a first-line treatment. Ultrasound guidance is essential for accurate tendon delivery.

❓ What shoes should I wear after an Achilles rupture?

After completing the boot/brace phase (typically 6–8 weeks), transition to a supportive shoe with a 10–12 mm heel-to-toe drop and a firm heel counter. Avoid flat shoes, flip-flops, and barefoot walking for the first 3–4 months. A temporary heel lift (12–15 mm) inside the shoe can further reduce Achilles strain during early rehabilitation. Running shoes from brands with Achilles-friendly designs (Hoka Clifton, ASICS Gel-Nimbus, Brooks Adrenaline) are frequently recommended by physiotherapists during the return-to-activity phase.

🥾 Do not switch to a lower-drop shoe until single-leg calf raise strength reaches at least 80% of the unaffected side — typically 6–9 months post-injury.

❓ Is Achilles tendinopathy the same as plantar fasciitis?

No — they are distinct conditions, though they share some risk factors. Plantar fasciitis involves the thick band of tissue running along the sole of the foot from the heel to the toes, causing pain at the base of the heel. Achilles tendinopathy involves the tendon at the back of the heel and lower leg. Both involve morning stiffness, overuse mechanisms, and respond to loading programs — but the anatomy, specific exercises, and footwear considerations differ. It is possible to have both simultaneously, particularly in runners with tight calf muscles and poor ankle dorsiflexion.

❓ Can children and teenagers get Achilles tendinopathy?

Adolescents are more likely to develop Sever’s disease (calcaneal apophysitis) — a growth plate condition at the heel that mimics Achilles pain — rather than true tendinopathy. However, genuine Achilles tendinopathy does occur in young athletes, particularly those in high-volume sports (gymnastics, distance running, basketball). In adolescents with open growth plates, aggressive eccentric loading should be applied with caution and under physiotherapy supervision to avoid apophyseal injury.
