If I keep my knees bent too long, it makes me hurt more. As for things moving in there, it's done that for the past 25 years now. LOL It could be related to the splint and pt though. When my knee did it, I had x-rays and found out I didn't have any muscle behind my kneecap like "normal" and it caused my knees to pop out of place all the time. Maybe the doc will do some x-rays to make sure nothing is floating around or have some other damage going on.

Hugs,
