Abstract
Autologous chondrocyte implantation (ACI) is an important operative option when repairing cartilage defects of the knee. This report introduces a new product development with one-stage ACI using a Reveille Cartilage Processor (Reveille CP) as well as the assessment of MRI and clinical results at a 1-year follow-up. The report compared cases between a 42-year-old female who underwent ACI surgery using Reveille CP and a 51-year old female who received treatment with two-stage ACI of tissue-engineered cartilage-like tissue (J-TEC Autologous Chondrocyte Cultured Cartilage [JACC]). One year after JACC, magnetic resonance imaging (MRI) showed signal intensity area in the grafted area, while patients with Reveille CP showed greater thickness than the surrounding healthy cartilage. The Lysholm, pain and QOL scores of Knee Injury and Osteoarthritis Outcome (KOOS) at one 1 year after surgery with Reveille CP were higher than JACC.
