I (44f) am looking at a knee replacement before 50. I’m 5’10”, overweight, work out 5 days per week , lifting classes and spin, and my joints have always been bad, even as a kid from sports and genes (autoimmune disorder). I want to stay active as long as I can. Has anyone had a replacement before 50 and regretted it? I have a torn meniscus and arthritis. I’m at the point where the chronic pain is keeping me from the gym. Also, I don’t see a lot of women on the page, is this a mostly men’s page?
