@wojo Welcome to Mayo Clinic Connect. You are experiencing pain behind the knee three months post op. You are looking to connect with members like you.

You will notice that I moved your question to a previous discussion where @tamryk recently discussed this topic.

Within the group, members like @buickturboman @eeppeerr88 @exflyer @toromama @coco @mrsflutterby @sprinrosa64 have discussed total knee replacements and may be able to help answer your question.

May I ask if you have completely the physical therapy exercises as instructed?
