mFat Therapy for the Ankle
From £5,800
View Price ListGuide price only. Final cost is confirmed after assessment.
mFat therapy delivers your own adipose-derived stem cells directly into the ankle joint to target inflammation, support cartilage preservation, and improve function. The ankle is a weight-bearing joint with a small cartilage surface, making it particularly susceptible to the effects of even limited cartilage damage. Biological treatment with mFat offers a way to manage degeneration and reduce pain without the permanence of fusion or replacement surgery.

Why the ankle responds well
to biological treatment
The ankle joint bears the full weight of the body through a cartilage surface roughly one third the size of the knee. This concentrated loading means that cartilage loss progresses quickly once it begins, and surgical options narrow as degeneration advances.
- Ankle cartilage has limited self-repair capacity once damaged.
- End-stage ankle arthritis often leads to fusion, which eliminates joint movement.
- Biological intervention at an earlier stage can slow progression and extend joint life.
mFat provides a concentrated source of regenerative cells that modulate the inflammatory environment within the ankle, creating conditions that favour tissue preservation rather than continued degeneration.
The procedure
and what to expect
Treatment is completed in a single outpatient session. The harvested adipose tissue is processed in a closed system to preserve the regenerative cellular components before injection into the ankle joint.
- Fat harvest under local anaesthetic with minimal discomfort.
- Image-guided injection ensures precise delivery into the ankle joint space.
- Most patients return to routine activity within one to two weeks.
At London Cartilage Clinic, mFat therapy for the ankle can be integrated with other evidence-based treatments as part of a broader management plan tailored to your joint condition and activity goals.
You may have more options than you think
Most patients have more treatment options than they have been told
At London Cartilage Clinic we follow a structured clinical framework across four areas of treatment. Before recommending a single procedure, we assess which combination of approaches gives you the best outcome.
Preserve
Protect what you have. Slow degeneration and manage symptoms.
Repair
Fix specific damage. Torn tissue, unstable joints, structural problems.
Regenerate
Rebuild lost tissue. Biological treatments that stimulate new growth.
Replace
When other options are exhausted. Joint replacement as a last resort.

Frequently Asked Questions
Which ankle conditions can mFat therapy treat?
mFat therapy is used for ankle osteoarthritis, talar cartilage damage, post-traumatic joint degeneration, and chronic ankle stiffness. It is particularly relevant for patients with early to moderate cartilage wear who want to delay or avoid ankle fusion or replacement.
How is the procedure performed for the ankle?
Adipose tissue is harvested from the abdomen under local anaesthetic through a small incision. The tissue is processed to concentrate the regenerative cells and then injected into the ankle joint under ultrasound or fluoroscopic guidance to ensure accurate placement.
Why is biological treatment important for the ankle?
The ankle has a smaller cartilage surface area than the knee or hip, meaning even modest cartilage damage can have a significant impact on function. Surgical options for the ankle are more limited, making biological treatments that support the existing cartilage particularly valuable.
How long before I notice improvement?
Many patients begin to notice improvement in pain and stiffness from two to eight weeks after treatment. The biological response develops gradually as the regenerative cells modulate inflammation and support tissue repair within the joint.
Can mFat be combined with other ankle treatments?
Yes. mFat can be used alongside PRP, hyaluronic acid, or as an adjunct to arthroscopic procedures. Your specialist will advise whether a combined approach would benefit your specific condition.
