MedlinePlus website on Knee Replacement Surgery shows important topics: total knee replacement surgery, joint replacement (arthroplasty), revision surgery, conditioning, rehabilitation exercises, deciding to have hip or knee surgery, and more. Many videos on minimally invasive surgery. We like MedlinePlus so much better than WebMD. It’s ad-free, a service of our National Library of Medicine (NLM) and the National Institutes of Health (NIH)
