Achilles Tendonitis
Achilles tendonitis is an overuse injury of the Achilles tendon, the thick band of tissue connecting the calf muscles to the heel bone. It can occur at the mid-portion of the tendon or at its insertion on the heel (insertional Achilles tendonitis). Chronic cases involve tendon degeneration (tendinosis) rather than acute inflammation.
Prevalence
Achilles tendon disorders affect approximately 6% of the general population at some point in life. Incidence is higher in runners (up to 10%) and increases with age. About 150,000 Americans experience Achilles problems annually.
Who It Affects
Common in runners and jumping athletes. Risk increases with age, tight calf muscles, flat feet, obesity, and sudden increases in activity. Men are more commonly affected than women. Fluoroquinolone antibiotics increase risk.

Common Symptoms
Common Causes & Risk Factors
Traditional Treatment Options
Rest and Activity Modification
Reducing or stopping activities that aggravate the tendon.
Limitations: May take months of reduced activity. Difficult for athletes and active individuals.
Eccentric Exercise Program
Specific heel-lowering exercises that load the tendon during lengthening.
Limitations: Requires 12-week commitment with twice-daily exercises. Success rates around 60-80%.
Physical Therapy
Stretching, strengthening, and gait retraining.
Limitations: Effective but requires significant time commitment. Chronic cases may not respond.
Shockwave Therapy
Extracorporeal shockwave therapy (ESWT) to stimulate healing.
Limitations: Variable results. May require multiple sessions. Can be painful during treatment.
Surgery
Debridement of damaged tissue or repair of the tendon.
Limitations: Reserved for cases failing 6+ months of conservative treatment. Long recovery (4-6 months).
Regenerative Medicine Approach
How Regenerative Therapy May Help
Regenerative medicine for Achilles tendonitis explores whether biologics may support tendon healing and recovery. The Achilles tendon has relatively poor blood supply, making it an area of interest for regenerative approaches that may deliver growth factors directly to the affected tissue.
Potential Benefits Being Studied:
- Contains growth factors relevant to tendon biology
- May help modulate chronic tendon degeneration
- Can deliver regenerative signals to poorly vascularized tissue
- Minimally invasive injection procedure
- May support recovery when conservative treatments fail
- Can be combined with eccentric exercise program
Biologics Used:
Mesenchymal stem cells delivered to the tendon
Exosomes with tendon-supportive growth factors
Frequently Asked Questions
Is there a risk of tendon rupture?
Achilles tendon rupture is a concern with severe tendinosis. Regenerative therapies have not been shown to increase rupture risk, but you should avoid high-impact activities during the healing period as directed by your provider.
Can I continue running?
Most protocols require temporary modification of running activity. Your provider will guide return to running based on your response to treatment and healing progress.
How is the injection performed?
Biologics are typically injected around or into the affected portion of the tendon under ultrasound guidance. Local anesthesia is used for comfort.
