title: [Cartilage biopsy for autologous chondrocyte implantation (ACI)].
abstract: Autologous chondrocyte implantation (ACI) is an established two-step procedure for the treatment of full-thickness cartilage defects of the knee. Cartilage harvest from the affected knee joint represents the first step of this procedure and is essential for further in vitro expansion of autologous chondrocytes. Nevertheless, the cartilage biopsy process itself is underrepresented in the scientific literature and currently there is only a limited amount of data available addressing this process. Biopsy location as well as the technique itself and instruments used for cartilage collection are not well defined and only little standardisation can be found. The article describes the relevant aspects of the biopsy in the context of ACI with regard to the literature available. Follow-up studies to better define and standardise the cartilage biopsy process are thus required.
