Had my left knee replaced and severe pain from day one. When I lay on my right side , bend my knee 45% and try to lift it straight up , severe pain on the outside of the knee. Absolutely can not lift it. I told the doctor this after one month, he just said it ould get better with time. 13 months later no difference same intense pain. Knee bends 90% and works fine except when I try tp privot inward to the right. If I walk up stairs and turn the knee inward at the same time it will collapse under me in pain. I can't walk on it when that happens and swelling occurs imediately after. What could it be ??? Could it be a muscle tear, a problem with the implant ???? Doctor will not address the problem. I have torn ligaments in the past on both knees and the pain has felt the same for the last year.
I've had the other knee replace 4 years ago and no problems at all.
