Great question. It depends. Cavitation of joints (the crack) is a nature phenomenon which can occur in all joints. It occurs when energy transferred into a joint release gas in the joints lubricating fluid. If you are doing a simple stretch or a naturally occurring motion, the “crack” is perfectly fine. If you are twisting your body or neck fast or torquing you head and neck, it my not be the best thing for your body. Many patients will fell the need to constantly “crack” their neck or low back to gain a sense of relief. It usually is an indication of spinal misalignment which should be addressed by a chiropractor. I hope this answers your question.

Knee pain can have a variety of cause starting with the knee. Improper biomechanics of the foot and hip can also cause stresses in the knee along with muscular imbalances and spinal misalignments.
