My knees are starting to bend inward due to me cracking them every morning. is it reversable?

I ddo not thing so: The knees bend inward for many reasons but not the one you mention. Some of the reasons 1-arthitis, with arthitis the inside part of the wear off and the cartilge were off and bone rubb agiast the bone. 2-some have ligment problems were one loose so the knee open up on that side, close on the other side. 3-main problem some sequnce to childhood problem, get worse with time.
