Correlation between the AMADEUS score and preoperative clinical patient-reported outcome measurements (PROMs) in patients undergoing matrix-induced autologous chondrocyte implantation (MACI)

Table 4 Correlation of the different AMADEUS score items in regard to the patient-reported outcome measures (PROM). The COMI score is the only PROM score showing significant correlation to subscales of the radiological AMADEUS score
