@patsortho Hello. Even though your situation is a little more involved then mind, it also sounds a lil similar. I think the issue is we both had the initial replacement and revision almost back to back. Two Dr's stressed to me that they try to avoid revisions because they are harder then the first and take longer to recover. One Dr even told me the next replacment is going be real major surgery due to the complexity. And I also had an MUA and I think it was due to having so much done on the same knee. And my knee isn't straight either, I am still about -3 with a slight bend in the knee. Overall I wanted you to know it seems to be getting better but at a SLOW rate. I know it's hard to wait but it will come. Good Luck with the MUA.
