Understanding Achilles Tendonitis
After 3 months, Achilles tendonitis is no longer an inflammation problem. It is a degeneration problem. That changes what treatment needs to do.
The Achilles is the body's largest tendon. It transmits the force of the gastrocnemius and soleus to the calcaneus during every step, jump, and push-off. Achilles tendinopathy develops when cumulative load exceeds the tendon's repair capacity, producing micro-tears and collagen disorganization.
Acute Achilles tendinitis (up to 6 weeks) involves inflammatory processes that respond to load reduction and structured loading. Chronic Achilles tendinosis (beyond 3 months) is characterized by degenerative changes, loss of normal collagen architecture, and reduced intrinsic vascularity. Anti-inflammatory treatments (including cortisone) have limited benefit in this stage and carry risk of tendon weakening. PRP addresses the degenerative tissue directly.
At Joint Freedom, we distinguish tendinitis from tendinosis by clinical history and ultrasound, guide PRP precisely to the area of degeneration, and combine laser therapy for accelerated recovery.

Who Gets Achilles Tendinopathy?
Runners are the most common presentation, followed by court sport athletes and recreational athletes who increase training load rapidly. Masters athletes are at higher risk due to reduced tendon collagen turnover with age.
Common Risk Factors
- Running with rapid training volume increases
- Masters athletes and recreational runners over 40
- Tight calf muscles and limited ankle dorsiflexion
- Flat feet or excessive foot pronation
- Prior Achilles tendon injury
- Fluoroquinolone antibiotic use (ciprofloxacin, levofloxacin)
Symptoms and When to Seek Treatment
Morning stiffness and pain with loading are the hallmarks. Worsening with training is a signal that tissue capacity is being exceeded.
Common Symptoms
- Pain and stiffness in the Achilles tendon first thing in the morning
- Pain 2 to 6 centimeters above the heel bone (mid-portion) or at the heel insertion
- Aching during or after running, jumping, or stair climbing
- Tenderness when pressing the tendon
- Thickening or nodularity of the tendon in chronic cases
See a Specialist If...
- Achilles pain has persisted beyond 6 weeks without improvement
- Pain is worsening with continued training
- A sudden sharp pop or snap felt in the heel area (possible rupture)
- Significant swelling or inability to push off the foot
Common Causes of Achilles Tendinopathy
Training errors, mechanical contributors, and the natural progression from tendinitis to tendinosis.
MOST COMMON
Training Load Errors
Rapid mileage increases, sudden addition of hill or speed work, and inadequate recovery between sessions are the primary drivers of Achilles overload. The tendon's adaptive capacity is outpaced by demand.
STRUCTURAL
Calf Tightness and Foot Mechanics
Tight gastrocnemius and soleus muscles increase Achilles strain under load. Overpronation and hyperpronation alter the mechanical environment at the insertion. Both are modifiable contributors.
DEGENERATIVE
Tendinosis
After 3 months, Achilles tendinitis transitions to tendinosis: disorganized collagen, reduced vascularity, and absence of healing. Anti-inflammatory measures lose effectiveness; regenerative approaches become the appropriate intervention.
How We Diagnose Achilles Tendinopathy
Clinical history distinguishes acute from chronic. Ultrasound characterizes the tendon and guides treatment.
Clinical Exam and History
We assess pain location (mid-portion vs. insertion), symptom duration, training history, calf flexibility, and foot mechanics. Mid-portion and insertional presentations require different approaches.
Ultrasound Assessment
Ultrasound visualizes the tendon structure, identifies areas of degeneration and increased vascularity, and guides PRP injection placement. MRI is used for complex or surgical planning cases.
Treatment Plan
Based on chronicity, location, and severity, we build a protocol combining laser therapy, PRP as indicated, and a structured progressive loading program tailored to your sport and timeline.

What You Can Do at Home
Structured eccentric loading is the most evidence-backed home intervention for Achilles tendinopathy.
What Helps
- Eccentric calf loading (heel drops off a step) under clinical guidance
- Calf stretching, particularly the soleus with knee bent
- Gradual progressive return to running with load monitoring
- Supportive footwear with appropriate heel lift
- Activity modification to reduce tendon load during acute phase
What to Avoid
- Cortisone injection into or immediately adjacent to the Achilles tendon (rupture risk)
- Run through significant pain hoping it will resolve
- Aggressive passive stretching into dorsiflexion during the acute phase
- Sudden return to full training after a rest period without progressive loading
How We Treat Achilles Tendinopathy
PRP for tissue remodeling and laser for inflammation, combined with structured progressive loading.
REGENERATIVE MEDICINE
PRP Therapy
Platelet-rich plasma injected under ultrasound guidance is the primary regenerative tool for chronic Achilles tendinopathy. Delivers growth factors to the degenerative tendon to support collagen remodeling and tissue repair.
LIGHTFORCE XLi
Laser Therapy
Class IV deep-tissue laser reduces pain and inflammation, supports cellular recovery, and is the appropriate first-line tool for early presentations. Used alongside PRP for chronic cases.
Which Treatment Is Right for Your Achilles?
Chronicity and pain location (mid-portion vs. insertional) determine the protocol.
01
ACUTE ACHILLES TENDONITIS (UNDER 6 WEEKS)
Laser and Loading Protocol
Laser series combined with structured eccentric loading and training modification. Most acute cases resolve within 4 to 8 weeks with this approach.
02
CHRONIC TENDINOPATHY (6 WEEKS PLUS)
PRP plus Laser
Ultrasound-guided PRP to support tendon remodeling, combined with laser therapy and progressive tendon loading. Results develop over 6 to 10 weeks.
03
INSERTIONAL TENDINOPATHY
Adapted Protocol
Insertional Achilles tendinopathy requires modified eccentric loading and injection technique. We adapt the approach for insertional vs. mid-portion presentations.
How Joint Freedom Compares
What you are actually weighing when you consider your options for Achilles tendinopathy.
 | Cortisone Shot | Surgery | |
|---|---|---|---|
| What it does | Supports collagen remodeling in the degenerative tendon, reduces pain, enables progressive loading without recurrent breakdown | Reduces peritenonitis inflammation temporarily | Removes degenerative tendon tissue surgically |
| Recovery time | None to minimal | None | 3 to 6 months |
| Addresses root cause | Yes | No | Partial |
| Long-term results | Durable tendon recovery with appropriate loading | High recurrence; increases Achilles rupture risk with repeated use | Effective for refractory cases; significant recovery burden |
| Risk of side effects | Minimal | Increased tendon rupture risk | Infection, nerve damage, re-rupture risk |

Questions About Achilles Tendinopathy
Answers from our clinical team.
After 3 months, most Achilles cases have transitioned from acute tendonitis to tendinosis, a degenerative process with disrupted collagen rather than acute inflammation. This distinction matters: anti-inflammatory approaches have limited effect on tendinosis, while PRP targets the degenerative tissue directly.
Rest removes the aggravating load but does not repair the underlying tendon degeneration. Tendons have limited blood supply and heal slowly. Without a stimulus for collagen remodeling, resting alone often leads to symptom return once activity resumes.
Yes, with modification. Eccentric loading protocols are actually part of evidence-based Achilles rehabilitation. We structure your activity modification around your treatment phase. Most patients maintain some form of cardiovascular activity throughout.
Mid-portion tendinopathy occurs 2 to 6 centimeters above the heel bone and is the most common type in runners. Insertional tendinopathy occurs where the tendon attaches to the calcaneus and is more common in less flexible individuals and older patients. Treatment approach and prognosis differ between the two.
PRP results develop gradually over 4 to 8 weeks as tissue remodels. Most patients report meaningful improvement by 6 to 8 weeks. A second injection may be considered at 6 weeks for incomplete responders.
No. PRP is delivered under ultrasound guidance to the tendon sheath or peritendinous tissue, not injected directly into the tendon body. This approach supports recovery without structural risk.
Surgery (tendon debridement or transfer) is reserved for cases that fail extended conservative and regenerative treatment, typically 12 months or more of documented attempts. Most patients with mid-portion tendinopathy see meaningful improvement before reaching that threshold.
