Hello @whiteda, I would like to add my welcome to Mayo Clinic Connect along with @kp6350 and other members. I had my right knee replaced in April 2019 and have felt tightness around the knee but it really hasn't bothered me much other than mild curiosity. @mikeycaz, @sweede536, @ruthannejoan, @shmabe and @ellerbracke have talked about the tight IT band syndrome in other discussions and may have some suggestions for you or can share their experience.

You might also find the following discussion helpful in learning what others have shared on the topic.

Has your surgeon recommend any exercises or physical therapy? Here is an article I found that talks about things you might want to try to see if it helps.
