Understanding Tendinitis

What Is Tendinitis?

Tendinitis is inflammation or irritation of a tendon — the thick fibrous cords that attach muscles to bones. When tendons are overused or subjected to repetitive stress, micro-tears develop, leading to inflammation, pain, and reduced function. Common sites include the shoulder (rotator cuff), elbow (lateral and medial epicondylitis), wrist, hip, knee (patellar), and Achilles tendon.

When Tendinitis Becomes Chronic

Acute tendinitis often resolves with rest, but chronic tendinitis (tendinopathy) develops when the healing process stalls. Chronic tendinopathy involves disorganized collagen fibers, failed healing responses, and persistent pain. Traditional treatments (rest, NSAIDs, cortisone) often provide only temporary relief for chronic cases. Repeated cortisone injections can actually weaken the tendon and increase the risk of rupture. Tendons heal slowly due to their limited blood supply. Chronic tendinopathy is actually a degenerative process rather than pure inflammation, which is why anti-inflammatory treatments alone often fail. Stem cell therapy addresses the underlying tissue degeneration.

How Stem Cell Therapy Helps

Tendon Regeneration

MSCs promote tendon healing by differentiating into tenocytes (tendon cells) that produce new, organized collagen fibers, releasing growth factors that stimulate the tendon's own repair mechanisms, promoting new blood vessel growth to improve tendon blood supply, and reducing the inflammatory mediators that perpetuate pain. A randomized controlled trial showed that MSC injection for chronic tendinopathy produced superior tendon healing on ultrasound and MRI compared to PRP or cortisone at 12-month follow-up, with 81% of patients achieving good to excellent outcomes.

Clinical Evidence

81%: Good to Excellent Outcomes
73%: Improved Tendon Structure on Imaging
88%: Return to Full Activity

Treatment at StemCell Longevita

Our Tendinitis Protocol

We use ultrasound-guided injection of MSCs directly into and around the damaged tendon. Precise placement ensures maximum cell concentration at the site of injury. Treatment is combined with PRP for enhanced growth factor delivery. Multiple tendons can be treated in a single session.

Treatment at Liv Hospital Ulus

Day 1 — Diagnostic ultrasound or MRI evaluation, physical assessment, and treatment planning.
Day 2 — Ultrasound-guided tendon stem cell injection.
Day 3 — Post-treatment assessment, eccentric exercise program initiation, and discharge.

Results & Recovery

Recovery Timeline

Pain improvement typically begins within 3 to 6 weeks. Tendon structural improvements develop over 2 to 4 months. Return to full activity is generally possible at 2 to 3 months for most tendon injuries. Imaging improvements in tendon structure continue for up to 12 months.

3-6: Weeks to Pain Improvement
2-3: Months to Full Activity
18+: Months of Sustained Benefits

Next Steps

If you have chronic tendinitis that has not responded to conservative treatments, contact us with your imaging and medical history for a free evaluation. Our orthopedic team will assess whether stem cell therapy can resolve your tendon condition.

Frequently asked questions

While PRP provides concentrated growth factors, stem cells offer a more comprehensive regenerative response — they produce growth factors continuously and can differentiate into new tendon cells. Many protocols combine both treatments for optimal results.

Gentle range-of-motion exercises are encouraged. However, high-load activities on the treated tendon should be avoided for 4 to 6 weeks. We provide a graduated return-to-activity program specific to your injury.

Stem cell therapy promotes actual tendon repair rather than just symptom relief, resulting in lower recurrence rates than conventional treatments. Addressing biomechanical factors and activity modifications further reduces recurrence risk.

Most patients require a single injection session. Severe or long-standing tendinopathy may benefit from a second treatment 3 to 6 months after the initial injection.
