Stem cell therapy for knee osteoarthritis in Spain utilizes autologous mesenchymal cells harvested from adipose tissue or bone marrow. The Spanish Agency for Medicinal Products and Medical Devices (AEMPS) strictly regulates these treatments as advanced therapy medicinal products under European Union standards and hospital exemption frameworks.
- Cell extraction: Surgeons harvest fat via mini-liposuction or extract bone marrow from the pelvic bone.
- Processing phase: Harvested tissues undergo centrifugation or culturing for 3–4 weeks to concentrate cell counts.
- Precision injection: Specialists inject concentrated cells into the knee joint using ultrasound or radiologic guidance.
- Regulatory oversight: AEMPS authorizes procedures on a case-by-case basis under Good Manufacturing Practice (GMP) standards.
Bookimed Expert Insight: Spain stands out for its application of cultured stem cells, a process often reserved for elite athletes. At Centro Médico Teknon in Barcelona, the protocol extends beyond simple concentration to growing millions of cells over several weeks. This approach is why major sports figures and FC Barcelona players choose Spanish clinics over standard outpatient centers. These advanced protocols involve 23 operating rooms and JCI-accredited safety, providing a higher level of precision than basic bedside kits used elsewhere.
Patient Consensus: Patients note that procedures are often done in under 60 minutes, allowing them to depart with ice packs the same day. Many report returning to 70% function within 3 months, though most advise avoiding high-impact sports for at least 6 weeks post-injection.
