If the pain is "on the inside of your kneecap" it could be meniscus or a ligament damage, but it could also be your patellofemoral joint, which is just a fancy term for the space behind your knee cap where it has a joint connection to your thigh bone (femur). Couple of questions about your knee. Where is the click when you bend your knee to 120 (top, side, under the knee cap, deep)? Does the click hurt? When you weight bear through the knee where do you experience the pain? Is there swelling in the knee? Is there any place that you can touch that causes the pain? What is the pain on a scale of 0-10 at rest and with activity?
Sorry to bombard you with questions, but it would be helpful to narrow down possibilities. Hope you have a speedy recovery.
Cheers to your health.
