I had tl left knee replacement Feb. 2007 I'm 62 yrs old fem. my problem is that my left knee , ankle and hip turn inwards when I walk this is causing allot of pain in my right hip, lower back and now I'm told I have tendinitis in my left groin. Could this be an error made when they replaced it. Before surgery I did not have this problem. Does anyone have anything similar happen to them. Many Xrays were taken by the orthopedic surgeon first time he said I was bull legged the secon time he said I was a little knock knee the third time he said no that's quite normal and when you get older this kind of problem occurs? I am currently taking phisio for the tendinitis but I'm told that the knee does turn inward and recommend that I wear a lift in my shoe.
