I am currently 46 years old and had an MCL replacement on my right knee a year and a half ago. My knee still had cartilage that was catching and preventing proper rehab. Five months ago I had arthroscopic surgery to clean it up. I am bone on bone with all of my ligaments loose. I was told by my doctor that I will need a TKR but have to wait until I am in my mid fifties. I have constant pain, limited mobility and I am not able to do many activities. I do not want to have to wait nine years to get possible relief. Any suggestions would be appreciated.
