I'm kind of surprised, the surgeon didn't rush to convince me I need surgery.
Essentially he asked "How much are your hips keeping you from doing what you want to do?" He did also mention that I have the start of arthritis blooming in my left hip, but that it isn't that bad yet. If it were to get markedly worse, there's a chance I wouldn't be a candidate for arthroscopy any longer. The cam deformity is going to accelerate that wear, so in that sense it's likely that having surgery would slow or stop any progression of arthritis.
When I think about it that way I start to lean toward wanting to move forward, especially since recovery isn't going to get any easier as I get older. , I guess.
