'Once it's lost, it doesn't grow back.'. With microfracture, surgeons drill puncture holes in the knee cap, which causes bleeding in the bone.This stimulates stem cells-which have the ability to form other types of cells-to create a scar-like version of cartilage.tem-cell implantation. Used for: Growing back cartilage. With this method, stem cells are removed from the patient's bone marrow under local anaesthetic.Arthritis Research UK is funding the country's first randomised controlled trial at The Robert Jones And Agnes Hunt Orthopaedic Hospital in Oswestry, Shropshire.
