Positive first response from medical community...

This survey is part of a study to compare two different scoring systems commonly used by surgeons to assess the success of cartilage repair surgeries.

In previous sections of this keynote, we have discussed options for repairing damaged cartilage in smaller cartilage defects. When the defect is large then surgeons are turning to two much more sophisticated techniques - ACI and MACI.

Both of these techniques involve taking a small amount of healthy cartilage from the patient, sending it to a laboratory to be grown as a tissue culture and then returned to the patient for implant.

In ACI the defect is sealed over with a membrance sewn over the hole, and the cells are injected behind the membrane as a suspension.
