I got injuried in 2008 and L&I approved surgery in 2009 because the knee was still so painful and swollen. Before surgery it was difficult to walk. After the surgery I was worse than ever because it is bone on bone. I could not walk for more than 20 minutes , standing was impossible, and stairs were a no go! After surgery/recovery time, I ended up going to a pain clinic/ physical therapy rehab for two months of intense physical therapy (tears daily). I finally am more mobile but the pain is still extremely high. I am on etodalac (anti inflammatory) which helps a TON.
I am only in my early 40's and I feel like I am 80. I really wished that I would not have had surgery.
I was not able to go back to my job and have major restrictions on what I can do now. It also hinders my sewing and driving.
I have heard a zillion stories of people with the tear having surgery and then they are fine. I am in the minority that get worse.
Good luck. Prayers will be sent your way.
