Hello @carlin, Welcome to Connect. Sorry to hear that your TKR did not go so well and you had to have a knee manipulation afterwards and arthroscopic surgery. It's understandable that you would be depressed but I would not feel bad about expressing how you feel. We know our body much better than any doctor and it's up to us to relay the information on how we feel to them. I also had a TKR a year ago April but am doing OK with range of motion and flex. I'm still working on strengthening the leg/knee though.

I really didn't know much about the manipulation process but found some information that explained it for me here:

@babette @contentandwell and others may have some suggestions for you.

Did your surgeon or care team provide any additional therapy or treatment after the arthroscopic surgery?
