I have not had a rebuild, but I have had a general clean up. It was not too bad, but it still takes time. My surgery was last February, and I am still not shooting at 100%. I can shoot my hunting bows 20 to 30 times, and then control breaks down due to fatigue. However in hunting one or at most two shots will be available.
Your rehab will be uncomfortable at best and will take a long time. But, if you work hard and LISTEN to the doc, plus DO THE WORK according to your therapist you will get back to shooting. You may never be able to pull bows as heavy as you do now, but just read a few threads here. Light bows will get it done. That will not be an issue for you. The main thing is just to hang in and get it done. Good luck to you. One last thing as a bright point, though. Once you do complete your rehab work, you will have justified buying yourself a brand new bow.
