The rotator cuff is a group of tendons that hold and move the shoulder, and the labrum is a ring of cartilage that deepens the socket. Tears are common with age and sport, and repaired tendons often re-tear because tendon heals slowly. Stem cells are being studied mainly as an add-on during surgery to try to improve tendon healing.

Does stem cell therapy work for rotator cuff tears?
Most human research uses stem cells as an add-on during surgical rotator cuff repair, not as an injection instead of surgery. A 2025 meta-analysis of 5 comparative studies (415 patients) found lower re-tear rates with stem cell augmentation (about 18% versus 35%), but pain, movement and shoulder function scores were the same as repair alone.
Many of these studies were not randomised and used different cell preparations. A 2020 systematic review of tendon disorders found mostly small, high-bias studies and advised against routine clinical use. Evidence for stem cell injections without surgery for rotator cuff tears is very limited, and there is essentially no good human trial evidence for labrum tears.
Is any stem cell treatment approved for rotator cuff tears?
No stem cell product is approved by the US FDA or EMA for rotator cuff or labrum tears. The FDA includes tendon problems among conditions for which no regenerative product is approved.
What private clinics offer — and how it compares
Clinics often sell shoulder injections of bone marrow, fat or birth-tissue products as a way to ‘heal a torn rotator cuff without surgery’. The research mostly involves cells added during surgery, and even then shows better scans but not better pain or function.
Proven treatments to discuss first
Before paying for an experimental option, make sure you have explored the established treatments for rotator cuff tears with your doctor:
- Physiotherapy and strengthening exercises
- Pain relief medicines such as NSAIDs
- Corticosteroid injection for pain to allow rehabilitation
- Activity modification and rest from aggravating movements
- Arthroscopic rotator cuff or labrum repair for suitable tears
- Shoulder replacement for severe tears with arthritis
How much does stem cell therapy for rotator cuff tears cost?
Private clinics typically quote $1,150 to $12,000. No shoulder-specific price survey was found; a US survey of knee stem cell injections found about $1,150–$12,000 (average $5,156), and a 2021 UC Irvine study found an average of about $5,100 per treatment. Insurance generally does not cover them. Compare prices by country in our cost guide and location guides, and check insurance coverage.
Risks and side effects
- Shoulder pain and stiffness after injection or harvest
- Infection at the shoulder or the bone marrow / fat harvest site
- Delaying repair of a fresh tear, which can make later surgery harder
- Unregulated products with unknown cell content or contamination
- High out-of-pocket cost for an unproven treatment

See all matching studies on ClinicalTrials.gov. A listing is not an endorsement: registration does not mean a study is safe or effective, and genuine trials rarely charge you for the experimental treatment. Ask the study team about costs, placebo groups and follow-up before you enrol. See our clinical trials hub.
Questions to ask before you agree to treatment
- Is my tear partial or full-thickness, and would a surgeon recommend repair?
- Is the stem cell product used alone or with surgery, and what trials support that approach?
- How will you measure whether the tendon has healed?
- What happens to my surgical options if this does not work?

Stem cell therapy for rotator cuff tears: FAQs
Does stem cell therapy work for rotator cuff tears?
When added during surgical repair, some studies show fewer re-tears on scans, but pain and function are about the same as surgery alone. Evidence for injections without surgery is weak. It is still considered experimental.
Can stem cells heal a torn rotator cuff without surgery?
There is no good evidence that stem cell injections can reconnect a fully torn tendon. Partial tears often improve with physiotherapy, and full tears in active people may need surgical repair.
How much does a stem cell shoulder injection cost?
US clinic prices for orthopaedic stem cell injections typically range from about $1,150 to $12,000, averaging around $5,000. They are usually paid out of pocket.
Is stem cell therapy FDA approved for shoulder injuries?
No. The FDA has not approved any stem cell product for rotator cuff, labrum or other tendon problems.
Is stem cell therapy for the shoulder covered by insurance?
Usually not, because insurers consider it investigational. Costs are normally paid by the patient unless treatment is part of a funded clinical trial.
