Many reasons: There are many reasons for fluid collections in the knee or swelling of the knee. Bone cancer/osteosarcoma can cause this problem but it is much more likely to be another cause. Trauma will cause these symptoms as will arthritis or degenerative joint disease. This should be evaluated by your primary care physician.

Knee problem: It is most likely from osteoarthritis and very less likely from osteosarcoma.

Possibly: This is a very difficult question to answer in 400 characters.Certainly a tumor is one of the least common causes of swelling around the knee. That being said, if you do have a tumor close to the knee, then it is possible that you can experience what we call a reactive effusion and thus experience fluid swelling or bleeding within the knee.
