This is quite normal and common, not a sign of arthritis or anything bad. What is really happening when your knees crack is you are actually pushing the joint either back into or out of normal position. Joints are covered by cartilage and held together by a strong, fibrous capsule and ligaments. A lubricant found in the space between the bones is called synovial fluid, which contains gas (mostly carbon dioxide and some nitrogen).
When you crack your joints, the bones on either side of the joint space separate reducing pressure on the synovial fluid. This allows the gas to form bubbles that quickly expand and pop, causing the characteristic "popping" sound you hear. The sound is relatively loud because the synovial fluid is thick like molasses.

Would suggest you are getting to that age where there is some structural changes which have caught up with you. You make no mention of the frequency of this event. Is something most people experience during their life. Is the cartilage slipping back into place. It is a horseshoe shaped cartilage and is beveled to allow the greatest movement of the joint..Some motion you make allows for there to be a bit more stress on the joint and does not allow the cartilage to return to its normal position.. when you bend the knee, it often will return with a rather loud popping sound. It can be felt also. I am well past 70 and have had this happen many times in my life but, still have no knee problems.

I had the same problem about 5 years ago, I also had a 'creaky' neck. I started taking one a day high strengh cod liver oil capsules,I now have no cracking and creaks and my skins not so dry. Don't expect results straight away, it will take about 2-3 months.

I see nothing wrong with that. Many individuals get "freaked out" by that sound. Just try to not do it.
