Figure 2. — Mean KOOS score at baseline and follow-up for both intention-to-treat populations. Mean delta KOOS was significantly higher than zero at 1 year: 9.7 (P = .02) in the ACI-C group and 15.0 (P = .002) in the AMIC group. Mean delta KOOS was significantly higher than zero at 2 years: 10.3 (P = .008) in the ACI-C group and 18.1 (P = .001) in the AMIC group. Error bars represent 95% CIs. ACI-C, collagen-covered autologous chondrocyte implantation; AMIC, autologous matrix-induced chondrogenesis; KOOS, Knee injury and Osteoarthritis Outcome Score.
