Patellofemoral Osteoarthritis Clinical Trial
Official title:
Treatment of Patellofemoral Osteoarthritis With Nasal Chondrocyte-based Engineered Cartilage Implantation in a Randomized, Controlled, Multi-center Phase II Clinical Trial
The purpose of this investigator-initiated study is to assess the efficacy of treating patellofemoral osteoarthritis with an Advanced Therapy Medicinal Product (ATMP), autologous nasal chondrocyte tissue engineered cartilage (N-TEC), in comparison with a standard therapy using platelet rich plasma injections. The engineered cartilage graft is obtained by culturing expanded autologous nasal chondrocytes within a collagen type I/III membrane.
