What this trial studies

This interventional study evaluates the effectiveness and safety of autologous chondrocyte suspension in treating knee articular cartilage defects. Participants will undergo a biopsy for cell production, followed by cell implantation and a strict rehabilitation protocol over 12 months. Assessments will include MRI evaluations, collection of adverse events, and orthopedic scores at multiple follow-up intervals (6 weeks, 3 months, 6 months, and 12 months). Informed consent is obtained from all participants prior to the procedures.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 15 to 50 with specific cartilage lesions that have not responded to prior treatments.

Not a fit: Patients with a BMI of 35 or more, active arthritis, or other specified exclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the healing and function of knee cartilage in affected patients.

How similar studies have performed: Previous studies using autologous chondrocyte implantation have shown promising results, indicating potential success for this approach.
