What Causes Knee Cap Instability?

Question: My knee was recently treated for cellulitis which I did not have and it was bruised and swollen and all that but now when I extend my knee and bend it just a little it clicks on the inside not the outer side the outer side feels like it shifted out of place as if my kneecap were turn about 25-30° to the right towards the inside of my leg I've been told I need a mri but have yet to recieve one as they are in high demand and expensive. I have insurance that's not the problem. But I also feel very difficult to bear weight if I try to stand on it the knee buckles and my weight is left to my other leg and I have to grab something . Any ideas about what the problem is?? I've been x rayed twice nothing's broken. Also I'm quite obese looking to drop some weight as well. But I just need the knee question answered . Thank you.
Brief Answer:
This is MPFL injury
Detailed Answer:
Hello XXXXXXX
I think you are having knee cap instability due to ligament injury. This ligament is called as MPFL . This helps in keeping knee cap in center of the knee. It can be weak since birth and can be broken with a slightest fall.This injury is more common as you are saying that you are obese. If on MRI diagnosis is confirmed then you will need a surgery to repair this ligament.
