Nanofat therapy

What is Nanofat?

Nanofat is mechanically emulsified and filtered autologous fat. During the processing, the pure fat cells (adipocytes) are largely destroyed; What remains is a cell and tissue-like concentrate that is rich in stromal-vascular components. These include, among other things, cells of the stromal vascular compartment, precursor cells (including adipose stem cell-like cells), perivascular cells and a cocktail of messenger substances and extracellular vesicles.

In contrast to classic autologous fat transplantation for volume creation (e.g. in plastic surgery), nanofat is extremely fine and can be injected into very small structures or periarticularly. In orthopedics, it is primarily discussed for tendon insertion problems, minor soft tissue problems and for symptom-oriented treatment of mild to moderate joint problems.

Possible indications – who is Nanofat suitable for?

Whether Nanofat is suitable depends on the symptoms, previous treatments and goals. The evidence is still limited compared to established conservative measures. Nanofat may be considered when standard therapies have been exhausted and surgery is not yet indicated or should be delayed if possible.

• Early to moderate joint arthrosis (e.g. knee, shoulder, saddle of the thumb joint) with predominantly stress-dependent pain
• Chronic tendinopathies and attachment tendinopathies (e.g. Achilles tendon, patellar tendon, tennis elbow), especially after unsuccessful conservative therapy
• Soft tissue irritation around joints (e.g. trochanteric pain syndrome) after differential diagnosis
• Small, localized cartilage and soft tissue problems in combination with conservative measures

Important: Careful diagnostics (anamnesis, clinical examination, imaging) is a prerequisite to distinguish useful indications from situations in which other therapies are clearly more suitable.

How it works – why Nanofat is being discussed in orthopedics

Nanofat contains cellular and non-cellular components that can modulate inflammatory mediators and support tissue healing. It is not a “filling material”, but rather a very fine-grained, biologically active suspension. An anti-inflammatory and matrix-regulating effect has been demonstrated in preclinical studies; clinical studies suggest possible improvements in pain and function in selected indications. However, reliable long-term data and high-quality randomized studies remain limited.

Nanofat is not a replacement for exercise therapy, weight management or structured conservative concepts. It can complement these measures if appropriate.

Nanofat therapy process in our practice

Time required: Typically 60-90 minutes including preparation. The procedure is outpatient. Ability to work at desk work usually possible the following day; Physically demanding activities should be tailored to the individual.

Reaction phase: In the first 24-72 hours there may be a moderate irritation reaction with swelling and tenderness. Initial clinical improvement, if it occurs, is often reported after 4-8 weeks; the overall assessment usually takes place after 12 weeks.

Evidence – what is certain and what is not?

Regenerative orthopedics is developing dynamically. There are case series and smaller controlled studies for Nanofat that suggest clinical improvements in selected indications (e.g. early osteoarthritis, tendinous symptoms). Strengths and limitations should be taken into account:

• Positive signals: pain reduction and functional gain in small study cohorts; good safety profile when carried out properly.
• Limitations: Heterogeneous protocols, different preparation procedures, limited randomized data, lack of long-term endpoints.
• Conclusion: Nanofat can be an option in the context of individual therapy decisions, but does not replace proven standard therapies.

We openly discuss what is currently proven and where data is missing. A treatment decision is made jointly and transparently.

Risks and side effects

Even gentle procedures are not free of risks. The overall safety profile depends on the indication, technique and individual factors.

• At the donor site: bruising, swelling, induration, temporary loss of sensitivity, rarely infection or scarring.
• At the injection site: pain, swelling, short-term increase or decrease in function, rarely infection, vascular or nerve irritation.
• Specific risks: Insufficient effect; very rarely fatty tissue necrosis or granulomatous reactions.
• Allergic reactions are unlikely because the body's own tissue is used; However, disinfectants or local anesthetics can trigger reactions.

We work under sterile conditions and use imaging for precise injections. An individual risk assessment is a mandatory part of the information.

Who is not suitable?

• Acute infections, febrile illnesses, local skin infections at the collection or injection site
• Uncontrolled coagulation disorders or anticoagulation without consultation
• Severe systemic diseases in an active inflammatory phase
• Pregnancy and breastfeeding (basically reluctance to have elective procedures)
• Findings that clearly require surgery or structural damage that require different approaches
• Unrealistic expectations or unwillingness to engage in accompanying activity and training therapy

If suitability is uncertain, we examine alternatives and obtain interdisciplinary assessments if necessary.

Nanofat, Microfat and SVF – what are the differences?

Adipose tissue preparations differ in their production, composition and potential areas of application. A precise demarcation helps with the selection:

• Nanofat: Mechanically emulsified, very finely filtered own fat; obese fat cells are largely destroyed; contains stromal-vascular components and messenger substances; easy to inject into fine structures.
• Microfragmented fat (microfat): Gently comminuted fatty tissue with preserved microstructures; is more suitable for cushioning or periarticular applications.
• Stromal Vascular Fraction (SVF): Cell fraction from adipose tissue with higher cell density; Extraction partly enzymatic or mechanical; special regulatory attention must be paid.

Which option makes sense depends on the findings, target tissue and regulatory framework. We provide you with differentiated advice and compare alternatives.

Conservative therapy first – our treatment principle

Before any regenerative procedure, we consistently review non-surgical options. Complaints can often be significantly improved with a structured plan:

• Physiotherapy, strength and coordination training, progressive load control
• Everyday and sports adjustments, aids, orthoses if necessary
• Weight management to relieve pressure on the joints
• Drug pain therapy as required and guidelines
• Injection procedures such as PRP (autologous blood) or hyaluronic acid when indicated
• Shock wave therapy for suitable tendon and attachment problems

We will consider Nanofat if these steps have been consistently implemented and the symptoms persist - and if the benefit-risk profile suits you.

Preparation and follow-up treatment

• Preparation: information, anamnesis, medication check. Medications relevant to coagulation will only be adjusted after consultation with a doctor.
• Procedure day: Comfortable clothing, light meal; Have someone accompany you when you feel more confident.
• Follow-up treatment: Protection of the treated region for 48-72 hours, cooling as required, no excessive strain. Gradual return to activity, accompanying physiotherapy.
• Controls: Clinical follow-up care after 6-12 weeks, assessment of pain and function, adjustment of the rehabilitation plan if necessary.

Sport: Casual everyday exercise is permitted early on, intensive sport is usually allowed after 1-3 weeks, depending on the region and symptoms, and is tailored to the individual.

Costs, reimbursement and legal information

Nanofat therapy is an individual health service in orthopedics. Statutory health insurance companies generally do not cover the costs. Private payers reimburse depending on the contract and individual case.

• Transparent cost planning in advance with a written cost estimate
• Individual information about benefits, risks and alternatives
• Compliance with applicable standards for tissue collection and use

We make no promises of healing. The aim is to make an objective, patient-centered decision based on the currently available evidence.
