Chondrocyte Implantation procedures (CCI), a cell based articular cartilage repair procedure that aims to provide complete hyaline repair tissues for articular cartilage repair, have been posed by some as an alternative to microfracture surgery. In February 2008, Saris et. al published a large-scale study claiming that CCI results in better structural repair for symptomatic cartilage defects of the knee than microfracture surgery. According to the study, one year after treatment, the tissue regenerate associated with CCI is of better quality than that of microfracture surgery.[15]
