my wife had it done 3 yrs ago. activity will start way before you are ready for it. she went to rehab for 3 months and kept doing the rehab on her own for over a year, you will know when to stop doing the exersizes, friend of mine had both done and was back to bass fishing in less than a month, everyone is a little different but all have to do the exersizes and acording to my wifes Dr. you can not over-do rehab.
good luckand I hope you are one of the fast healers
