Since you have a pre-existing injury, any advice given here would be unprofessional; you need specific rehab based on a good, in person, evaluation.
The various muscles of the chest, back, and shoulder -- anterior and posterior deltoids, pectoralis, subscapularis, etc., etc., etc. -- must be developed and strengthened, but they need, above all, to be balanced. That requires someone with expertise to set you up with a personal program.
I don't know by what title the proper licensed practitioners would be called in the UK; over here we call them physical therapists or occupational therapists, and you want one with a specialty in sports medicine.
HTH and good luck.
