What Is The Treatment For Ligament Tear In Ankle?

i hurt my ankle August 2010 xray showed ligament tear, was told to start physio immediately for 9 weeks. Ankle extremely painful and swollen. Re-xrayed late December, still showed ligament tear and post traumatic arthritis. What can I do to help this heal more quickly. Still sore and swollen. If I walk properly for one day, can hardly weight bear the next day.
