Open Access Abstract Introduction The present study established characteristics of tissue regrowth in patients suffering knee lesions treated with grafts of autologous chondrocytes grown on three-dimensional hyaluronic acid biomaterials. Methods This multicentred study involved a second-look arthroscopy biopsy 5 to 33 months post implant n 63 . Seven patients allowed a third-look biopsy three of which were performed 18 months post implant. Characteristics of tissues were histologically and histochemically evaluated. The remaining bone stubs were evaluated for cartilage bone integration. For data analysis biopsies were further divided into those obtained from postoperative symptomatic patients n 41 or from .
