The Achilles tendon is the largest and strongest tendon in the human body — and one of the most commonly injured. Achilles tendinopathy is a painful, often chronic condition that affects runners, weekend athletes, and people who have simply been on their feet too much. It can be stubborn, recurring, and deeply frustrating when standard treatments don’t provide lasting relief.
This guide is for people in Sydney’s north-west, the Hills District, and the Southern Highlands who are dealing with Achilles pain and want to understand the full range of options available — including why regenerative treatments like PRP are gaining traction as an effective approach.
Understanding Achilles Tendinopathy
The Achilles tendon connects the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus). It transmits the powerful forces of walking, running, and jumping — bearing loads of up to 8–10 times your body weight during running.
Tendinopathy refers to a degenerative process within the tendon itself, where the normal collagen structure breaks down and is replaced by disorganised, pain-sensitised tissue. This is distinct from an acute tendon rupture (a sudden, complete tear), though chronic tendinopathy does increase the risk of rupture.
There are two main presentations:
- Mid-portion Achilles tendinopathy — pain and thickening in the middle section of the tendon, typically 2–6cm above the heel. This is the most common form and responds well to loading-based rehabilitation
- Insertional Achilles tendinopathy — pain at the point where the tendon attaches to the heel bone. Often accompanied by a bony spur (Haglund deformity) and tends to be more resistant to treatment
Symptoms
- Pain and stiffness in the back of the heel, especially in the morning or after rest
- Pain that warms up during activity but returns afterwards
- Swelling or a visible thickening of the tendon
- Tenderness when pressing on the tendon
- Reduced ability to exercise or perform at your previous level
Conventional Treatment
The gold standard first-line treatment for mid-portion Achilles tendinopathy is a structured eccentric or heavy slow resistance loading programme. This involves specific calf raises performed in a slow, controlled manner, with progressive load — ideally guided by a physiotherapist experienced in tendon rehabilitation.
Other conservative measures include:
- Load management — reducing training volume and avoiding high-impact activities during the acute phase
- Heel raises — temporarily reducing the load on the tendon by raising the heel
- Shockwave therapy (ESWT) — evidence-backed, non-invasive treatment that uses acoustic waves to stimulate tendon healing; often effective for chronic cases
- NSAIDs — limited role; may reduce pain acutely but can interfere with tendon remodelling
- Cortisone injections — generally avoided for Achilles tendinopathy due to the well-documented risk of tendon rupture with repeated injections
When Conservative Treatment Isn’t Enough
A significant proportion of patients — particularly those with insertional tendinopathy or long-standing mid-portion disease — do not achieve satisfactory improvement with physiotherapy alone. For these patients, the next options have traditionally been shockwave therapy, PRP, or surgery. Given the risks associated with Achilles surgery and the lengthy recovery, most patients and clinicians prefer to exhaust all non-operative options first.
PRP for Achilles Tendinopathy
PRP therapy for Achilles tendinopathy involves injecting a concentration of your own growth factors directly into the degenerated area of the tendon under ultrasound guidance. The growth factors in PRP — including PDGF, TGF-β, and EGF — promote the synthesis of new collagen, reduce the abnormal cellular environment within the tendon, and stimulate vascular ingrowth that supports healing.
Clinical evidence for PRP in Achilles tendinopathy is encouraging, particularly for mid-portion disease. Studies have shown improvements in pain, tendon structure on imaging, and return-to-activity rates. Most patients receive one to two injections, combined with continued physiotherapy-directed loading.
PRP avoids the rupture risk associated with cortisone, uses your own biology, and has a very favourable safety profile — making it an attractive bridge between physiotherapy and surgery for patients who haven’t responded adequately to conservative measures alone.

Achilles tendinopathy requires an accurate diagnosis to distinguish it from other causes of heel pain, and an individualised treatment plan. At Dr John PRP, we assess patients from Castle Hill, Norwest, Baulkham Hills, Kellyville, Pennant Hills, Bowral, Mittagong, Moss Vale, and surrounding areas.
If Achilles pain has been limiting your activity and you’ve not found lasting relief, book a consultation to explore whether PRP might be right for you.
