“Does Cracking Your Knuckles Cause Arthritis?”
Many patients have asked me this question: “I crack my knuckles all the time, is that bad?” The answer is no. This is based on Dr. Donald L. Unger’s self-experiment. He cracked the knuckles on one hand every day for about 50 years and never cracked the other hand. After decades, he found no difference in arthritis or joint damage. He even won the Ig Nobel Prize in Medicine in 2009 for this study. He certainly deserves a medal for his persistence! (Seriously who does that?)
I do have a different opinion for people who crack their necks frequently. Maybe we can talk about that next time.
