My cousin started lifting with me two days ago and when he went to squat for the very first time he noticed that something, like a ligament maybe, pops out of place when he squats down. As soon as he stands up it pops back in. I have uploaded a video (if it worked) showing this happening on the side of his right knee. More towards the bottom of his knee.
Any advice on just about anything. From what this is and how will this affect his lifting to treatments etc? We will go get it checked soon but wanted to see if anyone knew what this was.
He feels no pain but says it feels really weird.
Thanks for your help in advance
