Knee stiffness is common as a result of arthritis, infection or injury. Various operations done on knee may also result in stiffness. Knee stiffness occurs due to the formation of excessive scar tissue (a mesh of rubber band like structures) or due to thickening of the knee capsule. It may also occur due to mechanical block caused by a displaced piece of bone.
