Augusto undergoes cartilage replacement operation
The Argentine midfielder underwent a new operation on his injured right knee on Tuesday, replacing cartilage with tissue that had been extracted in the first operation.
Second operation
Augusto Fernández underwent a second operation on his injured right knee on Tuesday, a complimentary intervention to the one he had back on 27 September. The procedure to which the Argentinean was submitted is known as Autologous Chondrocyte Implantation - a relatively-new technique in which damaged cartilage is extracted then new cells are grown in a laboratory for between four to six weeks. The reformed chondrocytes are then gratfed back on to the knee joint in a second, open-knee operation.
