There are three basic possibilities here;
-it could be something as simple as bubbles in the sinovial fluid popping, much like "cracking your knuckles";
-it could be something called "patello-femoral syndrome," in which the kneecap doesn't track straight. (If left untreated, PFS can cause serious damage to your knee/knee cartilage. Fortunately, PFS is easily corrected by learning and performing the proper exercises);
-or it could be symptomatic of something worse, like torn cartilage or the early stages of osteoarthritis.
If your knees snap and pop a lot, you should have them checked out by a qualified rheumatologist, especially if there's any pain or nausea involved; the pain caused by torn/damaged cartilage has a certain nauseating quality.
If it is torn/damaged cartilage, try working with a qualified rheumatologist and physical therapist before opting for arthroscopic surgery. Torn cartilage can be regenerated by up to 50% through physical therapy. However, once it is re-sected/removed by an orthopedic surgeon, it can't be repaired or replaced.
(A recently published study proved arthroscopic surgery does more harm than good in the majority of cases. Despite this, many orthopedic surgeons will try to talk you into having arthroscopic surgery anyway, because it's how they make their living.)
Before you trust an orthopedic surgeon with your life and future mobility, make sure you consult a qualified rheumatologist first!
This depends on how you fall. If you scratch or cut your knee, you will most likely bleed. If you bang your knee, then you will most likely get a bruise. If you bend or twist your knee in an unnatural way, then you could break, sprain, fracture, of rupture the ligaments or bone that makes up your knee.
Fluid in the knee can be a possible cause for gangrene to set in. The knee should be drained of fluid by a medical professional to prevent the onset of gangrene.
Perhaps you have jumpers knee. It really depends on what you have done with it lately. If you are a heavy sprinter and jumper than that is probably it. Most you can do is ice it and relax, as well as finding a knee band.
Edema means swelling. Edema of the knee or elbow means there is water on the joint. This is often caused by injury.
You may want to try prolotherapy or acupuncture. The more common treatment is an injection of a steroid into the joint.
It is very common for the knee to make funny noises as it moves. If there is no pain associated with it, it is nothing to worry about. It is usually caused either by 1) Gas bubbles popping (like bubble wrap) 2) Ligaments/tendons getting stretched and snapping back into place. See this site for more info

Popping and cracking noises in the knee are not unusual. If it's not accompanied by pain, it is probably not worth worrying about. Sometimes it's caused by the release of gases as the space between the two bones changes (the same phenomenon that causes your knuckles to crack or pop). Sometimes, it's caused by ligaments that rub or snap across a bone as it moves (like a rubber band snapping). [I'm a physical therapist--with arthritis]
The knee is both a hinge and pivot joint. The wrist is a condyloid joint. Although they are both joints in our body, the knee and wrist are different types of joints.
It is very common for the knee to make funny noises as it moves. If there is no pain associated with it, it is nothing to worry about. It is usually caused either by 1) Gas bubbles popping (like bubble wrap) 2) Ligaments/tendons getting stretched and snapping back into place. The theory that it makes you more prone to arthritis is just a myth. See this site for more info
