An MRI and CT scan evaluation of the condylar notch view showed (Figure 1) a 23 mm x 19 mm x 8 mm defect with ICRS grade IV lateral femoral condyle OCD.

Arthrotomy was performed, and gel-based ACI (CARTIGROW ) was implanted (Figure 2) directly onto the defect via injection drop by drop while maintaining gravity-eliminating position parallel to the floor to ensure that the implant did not overflow into the surrounding areas (Figure 3).

Arthrotomy was performed, and gel-based ACI (CARTIGROW ) was implanted (Figure 2) directly onto the defect via injection drop by drop while maintaining gravity-eliminating position parallel to the floor to ensure that the implant did not overflow into the surrounding areas (Figure 3).
The MRI evaluation posttransplantation showed improvement in cartilage defect.

IKDC score improved from 32 to 95, and the VAS score changed from 8 to 0 at 9 years. In addition, the MRI evaluation posttransplantation showed improved cartilage repair (Figure 4).
