I understand your concern regarding your symptoms.
Osteoarthritis is the most common form of arthritis and it
causes pain, swelling, and reduced motion in the joints. if there is no pain associated with the joint cracks or pops, this may be caused by the soft tissue in a joint. Knee popping may also occur if the patella is slightly out of alignment, and rubs on the adjacent tissues. Other causes of joint noise is the snapping of tendons or scar tissue over a prominence, or cavitation.
