T2 mapping magnetic resonance examinations. (4–1) right knee, (4–2) left knee; the arrows illustrate the implanted sites. (4–1-a) On the right knee, the thicker regenerated tissues with abnormal signals were detected at the implanted site 6 months after the primary surgery. (b) The thickness of the regenerated tissues was still slightly greater than that of the surrounding cartilage; however, the abnormal signals were decreased 14 months after the primary surgery and 1 month after the removal of the fixations. (c) The thickness and signal of the regenerated tissues became similar to those of the surrounding cartilage 2 years after the primary surgery. (d) The regenerated tissues were preserved 3 years after the primary surgery. (4–2-a) On the left knee, the surface was not smooth, and abnormal signals were detected at the implanted site 3 months after the primary surgery. (b) The surface was still slightly irregular, and abnormal signals were detected 14 months after the primary surgery and 1 month after the removal of the fixations. (c) The thickness of the regenerated tissues became similar, and the signals were almost the same as those of the surrounding cartilage 2 years after the primary surgery. (d) The maturation of the regenerated tissues was observed 3 years after the primary surgery
