Lateral Relase

Hi Im 14 and i have had knee problems for about 3 years after injuring them playing sports. Recently my pain has gotten so bad that i went to see the doctor and he has suggested that i get surgery, a lateral release, because PT has not help... After reading some things on the internet about what other people have been through and not being able to return to sports i have gotten very nervous.... I was wondering if someone could give me some good stories to help me get through this time... Thank you
