I "second the motion" to get another opinion. There are many "clowns" out there doing total knee replacements that are not skilled at doing them. Many people "go local" because they don't want to travel. I have had two knee replacements, one left hip replacement, and a reverse shoulder replacement. All of these surgeries were outpatient and I could have gone home the next day - but I don't live in Rochester; instead I went back to the hotel.
The same Mayo surgeon hip/knee replacement surgeon did both knees and my hip. Although I needed some pain medication (very short term) for the knees, I did not need any for either the hip or the shoulder. I know my knee surgeon has worked very hard to find out what problems patients have and he has worked with anesthesiology to make sure those problems don't happen to his patients. I had a shoulder specialist for the reverse shoulder arthoplasty; that also went very well. I walked to the hospital and walked home afterward; home was a hotel since we don't live in Rochester. (I certainly could have gone home if I was not from out of town.)
Please find a high volume center with a high volume surgeon and see what a new surgeon might do for you. I suspect that the University of North Carolina might be an option but please ensure that they have a high volume knee/hip orthopedic clinic and be certain to see one of their senior knee/hip replacement surgeons. Don't just accept an inexperienced low man/woman on the totem pole.
Don't put up with this nonsense. Stay away from the surgeon that did your knee. Find another asap.
