SURGEONS have pioneered a new knee operation that could prevent the development of arthritis and extend sporting careers.

The procedure, which is currently being trialled at Southampton General Hospital, involves coating damaged cartilage with stem cells, taken from a patient's own hip, and surgical glue.

Known as Abicus (Autologous Bone Marrow Implantation of Cells University Hospital Southampton), the technique, if successful, will regenerate the remaining tissue and create a permanent ‘like-for-like’ replacement for the first time.
