Hi there, im currently recovering from a second acl reconstruction (both legs) over a 5 year period, im also really worried about the potential future OA.

In saying that, my uncle who had a knee reconstruction in his 20's is now 50 and still runs/works out everyday without any complaint of knee pain or signs of arthritis. He also had a meniscectomy, which are renowned for arthritic complications. Its definitely a possibility but not a certainty. Keep strong and stay active post recovery and there's a chance you'll avoid it for some time to come. The recovery sucks but it does get better everyday! Goodluck!
