Knuckle Cracking Study Results:

The relation between habitual knuckle cracking and hand function was assessed among 300 patients aged 45 years and older, who had no evidence of nerve and muscle disease, inflammatory disorders, or malignant disease. Among the study group, there were 74 habitual knuckle crackers and 226 non-knuckle crackers. Although the prevalence of arthritis or inflammation of the joint was similar in both groups, hand swelling and lower grip strength were more prevalent in habitual knuckle crackers. Factors that were associated with habitual knuckle cracking included manual labor or work involving use of hands, nail-biting, smoking, and drinking alcohol. The results suggest that habitual knuckle cracking results in impaired hand function. (consumer Summary produced by Reliance Medical Information, Inc.).

Another reason in which it becomes hard to crack is because your knuckles begin to feel as though they need to be cracked in order to feel good. (http://forums.xkcd.com/viewtopic.php?f=18&t=43826)
