hey buddy, huge sympathy for ya!!
much of what Dazc has said really but main considerations are these:
1). Mine did not completely rupture therefore I still have proprioception which means my bodies software can still register stability and control. Both of which I trained progressively and religiously after I had reduced the swelling and regained full knee extension.
2). Just because it has fully ruptured does not mean you definitely need surgery HOWEVER what you have described is considerable instability, although from what I can understand it has been during moments of madness (or after a drink) or when 'cutting' (direction change).
3). Surgery can potentially give you back the stability you need for the games you wish to play
4). Probably THE most important consideration and the one that helped me to make my decision
You MUST remember this - you may come out of surgery worse than you went in - so your decision should be based upon your quality of life now and whether you are happy with it - if not then maybe surgery is for you.
Finally email me
rach@intelligenttrainingsystems.com and I will send you some rehab stuff if you like but it will probably look like the stuff your physio has done with you. Main focus being ham strength and stability/control/coordination work.
But do this for both legs as my good leg is now less stable than my ACL damaged one!!!!
Good luck
