Hello @janete718, Welcome to Connect. Sorry to hear you are having problems bending your knee at almost 8 weeks post op. I'm sure we have a lot of members who can relate. I was fortunate in that my knee replacement went fairly smooth with some minor patient caused issues, mainly I was not icing and elevating my leg enough.
You mention not being able to bend it enough. Can you tell us how much you can bend it, how much range of motion you have?
