@quiteachiver75 This is what my Dr told me long ago when the cracking started. and there is nothing we can do just live with it ,as a friend says it is what it is. One thing I use and it helps is get some kind of oil in me and rub oil on that area like I cook with Olive OIl use Hemp oil in my smoothie and rub peanut oil on my skin. A lot of our hyloronic acid oil with arthritis is depleted and I replace it forme this works . When my knees are hurting when I get up out comes the peanut oil . I dont know if arthritis can be inherited but Im full of it as my Mom was . She had 2 knee replacements and Im trying to avoid this . So betweent oil and knee brace Im doing o.k. God bless us all
