Acl surgery 12 weeks ago my knee feels loose did I do something to the graft or anything what does mean when my knee feels lose or graft loose?

If Ur knee feels -- -as it did B4 recon., it means that the graft has failed, either by Bing loose 2 start with & now it's symptomatic. Or the fixation of the graft has. This assumes U had no episode that put the graft @ risk. Get back in & talk 2 Ur surgeon. U do not have Marfan's by any chance? If so & Ur own tissue was used, that could B the cause. Need 2 use allograft in this case.
