hi Adelle, am sorry to hear about your ankle. I hope that all goes ok.
I am 8 months on from having 2 ankle ligaments reconstructed with tendon and all other ligaments in the same ankle tightened. the surgeon is really amazed that I hav'nt started subluxing again yet. He could'nt believe that I had been walking around for 18 months with just a bandage on and no crutches! As he put it after my surgery ' we moved you in theatre and your ankle dislocated before we touched it'. my reply was 'it did it everytime i took a sock off or lie on my right side!'.
My surgeon has been brilliant, he understands how fragile my tissue is. We agreed if i could get an 'almost normal ankle' from soft tissue surgery and get at least 2 years out of it I would be happy. If I somehow undo this repair we are considering artificial ligaments as a step before fusion. He is worried about how that would effect my knees as I am fairly active. It will all depend on whether or not I put my foot in a muddy hoof print again!
I was however in plaster for 4 months and was still struggling to walk properly until july/august. I am now waiting for new orthotics from Leeds, (I dont trust anyone else to make them).
It sounds to me like you have had a really rough time with your ankles, for a much longer time than me. am guessing from you post that all other avenues have been looked at? i think you are very brave to be going ahead with fusion, I would be scared too.
You are the only one who can make the decision about surgery as it is your body.
Let us know how things are going, take care.xx
