We set out to describe a 1-stage autologous chondrocyte co-implantation procedure and include quantitative characteristics of the biopsy tissues collected and of the cells obtained from those tissues in the operating room.<h4>Design</h4>Data concerning patient age, articular cartilage lesion size and location, as well as measurements of cartilage biopsy mass, bone marrow aspirate volume, and the cell yields harvested from those biopsies were intraoperatively collected for 141 patients.<h4>Results</h4>The mean patient age was 35.7 ± 9.8 years, and the mean total lesion size was 4.0 ± 3.1 cm².
