About 13 years ago when I was 44 I was told I had virtually no cartilage left in my right hip and had osteo-arthritis. I was told this was as a result of playing football since a young boy until my early 40's. I was offered a hip replacement several times over the following few years and did walk with a limp. To add to my troubles I am epileptic and suffer regular seizures and have fallen many times over the years sometimes injuring myself quite badly.

As the years passed I found my mobility improved and about 6 months or so I was out on a sports field and just gently jogged around and to my surprise and amazement I actually found I could complete a circuit of the field at a gentle pace. Since then I have been going out a couple of times a week and running further at a faster pace and can even sprint.

I am at a loss to explain this and have not told anyone about it but I keep reading articles stating that cartilage cannot regenerate so how can this be explained? I would love to hear if anyone can shed any light on what might have caused this change.
