Autologous Fat Grafting for the Treatment of Chronic Tendinopathy

Starting soon · Not applicable

Conditions studied: Chronic Tendinopathy

In brief

The goal of this clinical trial is to learn whether a one-time injection of a person's own concentrated fat (micro-fragmented adipose tissue, or MFAT) can reduce pain and improve function in adults (ages 18-80) with chronic tendinopathy - tendon pain lasting more than 3 months (for example, in the shoulder, elbow, hip, knee, or Achilles) - that has not improved with usual treatments such as physical therapy, cortisone shots, or platelet-rich plasma. The main questions it aims to answer are: * Does injecting a person's own concentrated fat into a painful tendon reduce tendon pain? * Does it improve how well the tendon works, how long does any improvement last, and is the procedure safe? This is a single-group study, so there is no separate comparison group; each participant's pain, function, and ultrasound results after treatment are compared with their own measurements taken before treatment. Participants will: * Have a one-time procedure in which a small amount of fat is removed from the abdomen by liposuction (under local numbing), concentrated, and injected into the painful tendon using ultrasound guidance. * Complete short pain and function questionnaires and have ultrasound imaging of the tendon at study visits. * Be followed for about 12 months, with a phone or video check-in 3-7 days after the procedure, a 2-week skin check of the fat-removal site, and visits at 6 weeks, 3 months, 6 months, and 12 months.

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age 18-80 years.
• Tendinopathy at any tendon location (e.g., rotator cuff/supraspinatus, lateral epicondyle, gluteal/hip, Achilles, patellar).
• Confirmed tendon pathology: pain at the tendon site for > 3 months AND pathology confirmed on ultrasound.
• Failure of conservative treatment (e.g., activity modification, physical therapy, NSAIDs, corticosteroid injection, and/or PRP) for at least 6 weeks.
• Able to provide informed consent and complete questionnaires in English.

You may not qualify if…

• Full-thickness tendon tear.
• Prior surgery at the target tendon site.
• Injection or other intervention at the target tendon site within the prior 6 months.
• Pregnancy or breastfeeding.
• Active local or systemic infection, bleeding diathesis or anticoagulation precluding the procedure, or other condition that in the investigator's judgment makes participation unsafe.
• Moderate-to-high-grade arthritis in the adjacent joint.
