Information for the public
There is not much good evidence about how well microstructural scaffold (patch) insertion without autologous cell implantation for repairing symptomatic chondral knee defects works. It should only be used if extra care is taken to explain the risks, and extra steps are put in place to record and review what happens.
Your health professional should fully explain what is involved in having this procedure, and discuss the possible benefits and risks with you. In particular, they should explain the uncertainty about the evidence on how likely it is to improve your symptoms. You should also be told how to find more information about the procedure. You should only be asked if you want this procedure after having this discussion. Your health professional should ask you if details of your procedure can be collected.
