I'm waiting to hear from my consultant - I tore mine in a fall in which my foot skidded sideways across the wet floor as I went down and my knee made a kind of right angle with my thigh. He mentioned "grafting" but I will know more when he has all the scan results etc. I have physio exercises to do (AGONY) which i thought were to strengthen it before the operation. I hope it's not instead of an operation! Good luck with yours.
