Hi everyone, I'm hoping to help my father figure out what happened to him during a swimming injury. He had a knee replacement done on both knees with implants... which is why we're so worried.

6 days ago he was swimming in a pool and slammed his heel into the wall when making a turn. His heel was pretty sore but more concerning was the pain he was getting in the front of his knee, right below the anterior (front) knee cap. We're worried that he loosened the implant from the knee replacement but I'm trying to research to see if there is some other connection to the heel impact. The knee pain continues but the heel pain has subsided.

He describes the pain feeling like "nerve pain" as it comes on suddenly, causing him to literally lose balance and cringe.

If anyone has any insight on this I would truly appreciate it! Thanks in advance.
