Shoulder Injury - Labrum Tear

I just got back from my last visit with my sports medicine doctor and he has recommeded orthoscopic surgery on my shoulder. After at least nine months of xray's, an mri, a cortizone shot, and a great rehab program the pain and catching in my shoulder just won't go away. After 30+ years of swimming and never having an injury that required surgery, I'm a little reluctant go under the knife. I wondering if any of you can give me some advice regarding labrum tear surgery, rehab, and recovery time. I am having a second opinion..... but would like to have more.. Thanks everyone.. Dennis
