The most important clinical decision with Achilles Tendinitis Treatment: The Evidence-Based Protocol That Works isn’t which treatment to choose — it’s identifying which subtype you have first. Our podiatrists see patients treated for the wrong subtype for months before the correct diagnosis leads to full resolution. Call (810) 206-1402 — expert podiatric care across Michigan.
| Treatment | Best For | Evidence | Timeline |
|---|---|---|---|
| Eccentric heel drops (Alfredson protocol) | Mid-substance tendinopathy (non-insertional) | Strong — multiple RCTs; 60–80% improvement | 12 weeks of daily exercises |
| Heavy slow resistance (HSR) training | Both insertional and mid-substance | Strong — superior to eccentric alone in some RCTs | 12 weeks |
| EPAT / shockwave therapy | Chronic insertional tendinopathy (>3 months) | Strong — FDA-cleared; 3 sessions over 3 weeks | 3 weeks treatment; improvement over 3 months |
| PRP injection | Mid-substance with partial tear; failed other treatments | Moderate — conflicting; best evidence for mid-substance | Single injection; 6–12 weeks recovery |
| Heel lift / offloading | Insertional tendinopathy; reduces tendon compression at heel | Moderate — removes painful compressive load | Immediate symptom reduction; continue 3–6 months |
| Stretching (gastrocnemius/soleus) | Mid-substance; tight calf contributors | Moderate — note: avoid aggressive stretching for insertional | Ongoing; part of all protocols |
| Surgery (debridement + repair) | Failed 6–12 months conservative; significant tendon degeneration | High for appropriate candidates | 6–12 months recovery |
Treating Achilles Tendinitis: The Evidence-Based Approach
Achilles tendinitis treatment depends critically on whether the condition is insertional (affecting the tendon’s attachment to the heel bone at the back of the heel) or non-insertional / mid-substance (affecting the tendon 2–6cm above the heel). These are two distinct pathological processes requiring different treatments. The most common error in Achilles treatment is applying the same protocol to both — specifically, eccentric heel drops (the most effective treatment for mid-substance tendinopathy) can actually worsen insertional tendinopathy by compressing the tendon against the calcaneus at the bottom of the drop.
Mid-Substance Achilles Tendinitis: Eccentric Loading Is the Standard
For non-insertional Achilles tendinitis, the Alfredson eccentric heel drop protocol is the most evidence-backed treatment: standing on the edge of a step, rise onto both toes, then lower slowly on the affected foot only, allowing the heel to drop below the step level. Three sets of 15 repetitions, twice daily, for 12 weeks — including through mild pain. The counterintuitive instruction to exercise through pain is intentional: the load is what stimulates tendon remodeling. Studies show 60–80% of patients achieve significant improvement with 12 weeks of consistent eccentric loading. Heavy slow resistance training (HSR) — calf raises on a leg press with heavy load and slow tempo — has shown comparable or superior results in more recent RCTs and is better tolerated.
Insertional Achilles Tendinitis: Avoid Eccentric Drops
Insertional tendinopathy involves calcification and degeneration at the tendon-bone junction, often with a prominent posterosuperior calcaneal exostosis (Haglund’s deformity). The compressive load of the full eccentric heel drop worsens this condition. Treatment instead focuses on: heel lifts (raising the heel in the shoe to reduce tendon angle and compression against the bone), isometric calf raises (straight knee), heavy slow resistance training in a neutral position, and EPAT shockwave therapy. Cortisone injection is generally avoided at the tendon insertion because it carries a risk of tendon rupture in this high-load location. Surgical options include calcaneal bony spur removal (Haglund resection) combined with tendon debridement and repair.
At Balance Foot & Ankle, Dr. Tom Biernacki and Dr. Carl Jay provide Achilles tendinitis diagnosis and treatment including EPAT shockwave therapy, PRP injection, and surgical repair at both the Howell and Bloomfield Hills offices. Call (810) 206-1402.
⚠️ See a podiatrist right away if you have:
- A sudden “pop” or snap felt in the back of the heel — possible Achilles rupture
- Cannot rise on your toes at all on the affected side
- Visible gap or indentation in the tendon 2–4 cm above the heel
- Severe swelling and bruising appearing within hours of onset
- Pain that is getting worse rather than better after 2 weeks of rest
Heel Lift Inserts First-Line Conservative
A 6–9mm heel lift is often the fastest way to reduce acute Achilles pain. By shortening the Achilles at rest, it reduces tensile load on the inflamed tendon and typically provides noticeable relief within the first few days. Use in both shoes to avoid creating a leg-length discrepancy. We transition patients off lifts over 8–12 weeks as the tendon heals and we introduce progressive loading exercises.

Doctor Answer
What is the most effective treatment for Achilles tendinitis?
Achilles tendinitis responds best to a structured eccentric heel-drop exercise program, which progressively loads the tendon to promote healing. Supportive footwear, heel lifts, physical therapy, shockwave therapy, and NSAIDs are also effective. Complete rest is generally discouraged — controlled loading heals tendons better. Platelet-rich plasma injections may be used in stubborn cases. Surgery is reserved for tendinosis that fails 6 or more months of conservative treatment.
