Regeneration of knee and ankle joint cartilage from autologous cells (from the patient's own cells)
Descrizione riassuntiva dello studio
General information about the project The study consists of 3 phases: - Collection of a small cartilage sample - Sending the sample to the laboratory (clean room) to extract the cartilage cells (chondrocytes), culture them, and produce the mini-grafts of cartilage (Cartibeads) using a patented innovative technique (duration 7-8 weeks, variable depending on patients) - Transplantation of the grafts into the cartilage lesions through a new minimally invasive surgery This study plans to recruit 10 patients suffering from ankle/knee cartilage lesions. Each recruited patient will be followed for a period of one year after the implantation of the grafts to ensure the absence of adverse effects. The follow-up will also allow for the evaluation of the success of the implantation. An extension of the follow-up will be offered to each patient who wishes it at 2 years, 5 years, and 10 years after the implantation of the grafts. This follow-up extension will be part of another clinical study for which a new consent document will be submitted to patients who wish to participate, in due course. This project is carried out in compliance with the provisions of Swiss legislation. The competent cantonal ethics commission has reviewed and authorized this clinical study as well as the Swiss Agency for Therapeutic Products (Swissmedic).

Intervento studiato
In this study, the proposed cartilage is generated from the patient's own cells. It is developed in the laboratory over 7 to 8 weeks and appears as small cartilage grafts with a diameter of 1 to 2 mm (called cartilage microtissues or Cartibeads), minimally invasively transplantable, with characteristics similar to those of native hyaline cartilage.
