Stem cell therapy

What does stem cell therapy mean in orthopedics?

In orthopedics, the term stem cell therapy usually refers to applications with mesenchymal stromal cells (MSCs) that are obtained from the body's own tissue - typically from bone marrow or fatty tissue. These cells can release growth factors and messengers that modulate inflammation and promote tissue healing. This should not be confused with PRP (platelet-rich plasma), which does not contain cells but rather a concentrated mixture of platelets and growth factors.

In practice, minimally processed (autologous) preparations are usually used. Processes in which cells are propagated or extensively modified in the laboratory are subject to strict pharmaceutical regulations in the EU and are not the norm in private practice settings. Which method is suitable in each individual case depends on the diagnosis, previous findings, comorbidities and individual goals.

• Goal: support the body's own healing mechanisms
• Sources: bone marrow, fatty tissue (autologous)
• Delimitation: PRP is a biological but cell-free therapy
• Regulatory: more heavily manipulated cell products are strictly regulated

Who can benefit from stem cell therapy?

Cell-based therapy can be considered as a supplement to standard therapy for selected orthopedic diseases - especially if conservative measures have already been consistently implemented and relevant complaints still exist. The decision is always individual and is made after information about the benefits, risks, alternatives and the current evidence.

• Early to moderate osteoarthritis (e.g. knee, hip) to relieve pain and improve function
• Focal cartilage damage (depending on size, location and accompanying factors)
• Selected tendon and ligament problems with a chronic course after conventional options have been exhausted

Not every complaint benefits from stem cell therapy. The assessment is based on anamnesis, clinical examination and modern imaging. We also weigh up accompanying factors such as axial misalignments, instabilities or overload patterns - because without optimizing these causes, the effect of any biological therapy will evaporate.

Procedure at a glance

Depending on the findings, different cell-based or biological methods may be useful. Below you will find our detailed pages with indications, process and special features.

• Fat stem cells: Obtained from fatty tissue; The aim is an inflammation-modulating and tissue-supporting effect (see detail: fat stem cells).
• Bone marrow stem cells: Obtained from bone marrow; Use e.g. B. for cartilage and joint problems (see detail: bone marrow stem cells).
• Ear cartilage-based chondrocytes: Cell-based cartilage therapy, no stem cells - option for selected cartilage damage (see detail: Ear cartilage-based chondrocytes).
• PRP therapy: Cell-free but regenerative option to support healing processes.
• Shock wave therapy (ESWT): Mechanical stimulation to reduce pain and promote healing.
• EMTT: High-energy magnetotransduction for complementary pain and regeneration therapy.
• Laser regeneration: Photobiomodulation to support tissue healing.
• Neuroregeneration: For nerve involvement to improve nerve healing and pain modulation.

Process in our practice in Hamburg

The entire therapy is a process: Not only the injection itself is crucial for success, but also consistent follow-up treatment, muscular stabilization, weight management and everyday training planning.

Scientific evidence: opportunities and limitations

The study situation on stem cell therapy in orthopedics is developing dynamically. For knee osteoarthritis, several studies indicate improvements in pain and function compared to placebo or certain standard procedures. At the same time, studies are heterogeneous (cell source, preparation, dose, accompanying measures), and not all results can be directly compared. There are promising, but partly early, data for focal cartilage damage and tendon problems.

• The method does not replace causal correction of axis errors, instabilities or pronounced structural defects.
• Long-term data over several years is limited; Open questions concern optimal dosage, preparation and patient selection.
• Not every patient benefits - careful indication is crucial.

We see stem cell and cell-based therapies as a building block in an integrative treatment concept that combines conservative pillars with modern regeneration - without any promise of cure.

Risks and possible side effects

Like any invasive measure, cell-based therapy is associated with risks. Serious complications are rare, but cannot be ruled out. Transparent information in advance is a matter of course for us.

• Donor site: pain, bruising, swelling, rarely infection.
• Injection site: temporary increased pain, swelling, irritation; rarely infection, bleeding.
• Systemic: Intolerance reactions are rare but possible with autologous procedures.
• General: no or little effect, delayed treatment benefit, need for further treatments.

When is caution necessary? Contraindications

• Acute infections or skin lesions in the treatment area
• Uncontrolled coagulation disorders or ongoing anticoagulation without the possibility of adjustment
• Active tumor disease or recently treated malignant diseases (individual clarification required)
• Severe, decompensated general illnesses
• Pregnancy/breastfeeding (individual benefit-risk assessment)
• Unrealistic expectations or unwillingness to provide consistent follow-up treatment

We will clarify in a personal conversation whether one of the situations mentioned applies and what adjustments are possible.

Alternatives and useful additions

Regenerative processes best develop their potential in conjunction with strong, conservative pillars. Cleverly combined measures often lead to more stable results than individual therapy.

• Physiotherapy and individualized training plans (strength, coordination, mobility)
• Stress and everyday coaching, weight management
• Orthotics/insoles, taping, sport specifics
• Medicated pain and inflammation management (appropriate to the situation, limited in time)
• PRP, ESWT, EMTT, laser regeneration as additional options
• Surgical procedures for advanced damage (e.g. corrective osteotomy, cartilage surgery, endoprosthetics) - only after careful indication

Costs and reimbursement

Many cell-based procedures are not covered by statutory health insurance in Germany. Private payers often make decisions on a case-by-case basis. We will provide you with a transparent cost estimate in advance and support you in clarifying this with your insurance company. Specific amounts can only be reliably stated after diagnosis and the individual procedure has been determined.
