I tore out part of my DUSOLVABLE INTERNAL stitches by accident, is this a problem?

I had ACL reconstruction surgery using a hamstring graft 3 weeks ago and for the past week I've been picking at this thing that I thought was a scab that was located on the top of my lower incision. I finally got it out today and this clear string came with it. I later realized it was not scab that I had been picking at but the knot where the surgeonhad tied my stitches, it was on the outside of my leg. I took that out and had 1-3 cm of suture material come out too. then a little tiny bit if blood and a clear fluid. I put a band aid on it. is it worth a call to my surgeon or physical therapist seeing how we are doing physical therapy in a dirty public pool now. is infection going to be a problem? is it going to still heal properly? my surgery was on 3/18/2011. thank you
