Felt a pop in my knee and collapsed but no pain and the mobility is the same

I was doing 10 kicks on the pads today and halfway through I felt my knee pop and I fell. I didn’t feel pain and the mobility is fine. It just feels very awkward and can’t put much weight on it. I was able to get up and walk but not without limping. I’m tweaking out rn because I’ve had many leg injuries before including a massive surgery to repair my other knee. If it’s a tear I don’t know if I’ll be the same again and I don’t know if my insurance will want to cover another surgery. Has anyone ever experienced something like this or know someone who has before I think about getting an another mri on my insurance. I need all the knowledge I can get.
