I had shoulder surgery, it's weak and hurts a lot when it should have been better months ago?

I had surgery in august of last year for a shoulder dislocation, rotater cuff is fine, just some ligaments had to be repaired. I got good a good prognosis, and over the healing time it was hit a few times, and once out of sling it accidentally caught my fall once by reflex, and hurt pretty bad (has not been dislocated since surgery though). I was supposed to be 99% by February or March. I did not do all of my physical therapy at home once I completed all my sessions. I went for a checkup, and he told me what I needed to strengthen, because it may have been stretched out a little. If I strengthen my shoulder up really well, will it ever reach 100%? I am concerned because I'm going into the military. The field I will be going into is intense in terms of strength, especially the shoulder joints. So if I need surgery Im getting it again asap, but I need to know if I will be okay if I restart home PT to strengthen the weak parts so I can finally reach 100%, or will I only get to like 90% and wind up hurting it in training? Basically my question is, if my ligaments have stretched out again, can I workout the muscles so the joint is more stable, and be completely normal again without surgery? Much appreciated for your time.
