As the only public hospital in Spain performing this advanced regenerative medicine technique for knee and ankle cartilage repair, the center validates over twenty years of orthopedic expertise.
- Cellular Repair: The procedure uses a patient’s own cartilage cells, harvested from non-weight-bearing areas, to grow millions of new cells in a specialized laboratory over a three-week culture period.
- Target Patient Profile: The treatment is designed for young and middle-aged active patients with localized cartilage or osteochondral lesions, helping prevent premature osteoarthritis and the need for artificial joint replacements.
- Two-Stage Protocol: Care involves an initial minimally invasive ambulatory surgery followed by a second surgical intervention to implant the expanded chondrocytes via a biological membrane fixed with fibrin glue.
Two Decades of Regenerative Traumatology in Valencia
This accreditation recognizes more than twenty years of specialized work by the hospital's Orthopedic Surgery and Traumatology Service. The institution stands out as the only public hospital in Spain executing this intricate cellular therapy for both knee and ankle joints.
Lacking blood vessels and possessing a limited capacity for regeneration, hyaline cartilage cannot repair itself effectively after traumatic injury. When sports accidents, falls, or acute trauma destroy this smooth, shock-absorbing surface, the resulting defects trigger pain, inflammation, and loss of mobility. Without intervention, these localized focal defects can favor the early development of osteoarthritis in young and active people.
“Hemos realizado más de 200 trasplantes autólogos de condrocitos en gente joven y activa con lesiones condrales y osteocondrales en rodilla y tobillo,” stated José Luis Rodrigo, head of the Orthopedic Surgery and Traumatology Service at the hospital. He added that “la mitad de estos trasplantes se ha realizado con una técnica nueva de cultivo expandido que es más efectiva,” noting that the institutional recognition provides a quality benchmark for the surgical team’s efforts.
The Two-Stage Surgical Mechanism of Action
These harvested tissues are placed in a cell culture medium and sent to a specialized laboratory. Over three weeks, the chondrocytes are isolated and multiplied into millions of cells. The construct is subsequently secured into the lesion using fibrin glue, facilitating the formation of new cartilaginous tissue without internal scar formation.
| Procedural Phase | Clinical Action | Duration / Setting |
|---|---|---|
| Phase 1: Cell Harvest | Minimally invasive extraction of healthy cartilage from non-weight-bearing zones. | Ambulatory outpatient surgery |
| Laboratory Expansion | Isolation and multiplication of chondrocytes over a three-week culture window. | Specialized cell culture facility |
| Phase 2: Implantation | Seeding cells onto a biological membrane and fixing into the lesion with fibrin glue. | 24-hour inpatient hospital stay |
Epidemiological Impact and Regional Healthcare Integration
By securing this official designation, the Hospital Universitario Doctor Peset functions as a reference unit for patients presenting with specific chondral and osteochondral pathology. The technique addresses a challenging demographic: physically active individuals who experience joint symptoms but present without advanced osteoarthritis.
According to institutional statements, utilizing the patient's own biological material "se reduce de forma importante el riesgo de rechazo inmunológico del trasplante." This biocompatibility safeguards the transplant while offering a biologic alternative to prevent the need for prostheses in young cohorts.
Contraindications & When to Consult a Doctor
Contraindications include advanced osteoarthritis. Patients presenting with focal joint pain, inflammation, or loss of mobility following sports injuries or falls should consult an orthopedic specialist to determine candidacy for advanced joint preservation therapies.

Looking Ahead in Regenerative Orthopedics
As regenerative protocols evolve to incorporate expanded cell lines, the focus remains on halting cartilage degeneration before irreversible arthritic changes occur. The technique is applied to lesions in the ankle and knee, specifically the femoral condyle and patella.
