Effectiveness and Safety of Knee Cartilage Lesion Treatment Using CartiONE: 1-to-13 Year Follow-up.

CartiONE is a technique used in autologous articular-chondrocyte-based treatments for symptomatic focal articular-cartilage lesions of the knee. The CartiONE technique was evaluated in combination with an osteochondrally placed, biodegradable, biocompatible, load-bearing copolymer (PolyActive) scaffold in the INSTRUCT trial (NCT01041885). To evaluate the clinical effectiveness of the CartiONE technique and confirm its safety, in this study retrospective baseline data and follow-up data, documented as per the standard of care at the participating hospitals, will be collected for patients who were treated with CartiONE. The potential number of patients in this study is 122 and involves patients treated with CartiONE from 2010 to 2023 with a minimum follow-up period of six months, spread across five countries: Belgium, England, Greece, Poland, and Austria.
