My daughter had ACL surgery 18 months ago and has been playing college soccer for the past 6 months. She was playing indoor pick up yesterday when she twisted and had pain in her knee. She didn't hear the dreaded pop but stopped playing and was very worried. Her knee is painful, mostly on inside of knee, but she can walk with a small limp and bend/extend. Since she had ACL surgery on this knee I am wondering if we need to get in to an ortho immediately or wait a few days and see how it feels?
