Is there any solution

Question

I had a broken head of the humerus, they made me a laterjet, and it got infected, they operated on me and they removed my prosthesis, then they did an arthroscopy to clean the joint, my doctor says that I lost the cartilage due to the infection, I have instability i feel like it moves out of place But not enought to get out, I am 17 years old, I really want to train again, but the doctor says that if I force myself without cartilage, my shoulder will wear out prematurely, I am totally forbidden to do force and movements Quick, I asked the doctor if I could have a shoulder replacement, but he says that I do not qualify for surgery because of my age, it is very frustrating for me not even to be able to play with my friends for fear of something happening to me, also it hurts all the time. time, it's a bearable pain but it's very annoying Is there any solution? Can this surgery be performed at my age?
