What was your experience like? Last night I was doing wide stance box squats with my toes pointed way out. I've only been doing this for a couple weeks, so I'm not totally used to them and I think my knee wasn't quite tracking directly over my toe. On the second rep of my last set I hear this "SCRRRRRITCH" and felt a distant tearing sensation... it sort of reminded me of a piece of tape being ripped off of skin. It felt like my patellar tendon separated a little bit, maybe a quarter to half an inch.
Today my knee feels a little uncomfortable, but if I hadn't had that sensation last night I doubt I'd think anything was out of the ordinary, so there's no significant pain or anything. Does this sound like a real tear? Should I see the doctor?
