Did a knee injury cause cartilage damage or is it inherited?
You have not stated what the cause of the original knee problem was and if there was any medical intervention of any kind. No age was also given and that is a factor as well as weight and what kind of shape you are in. The four years span is enough to have allowed a degenerative process to have occurred. If the ligament was injured badly enough and there was no treatment for it that would have allowed the meniscus to deteriorate. The injection series of three is usually hyalaronic acid commonly know as Synvic. That gives a temporary artificial cartilage. A suggestion would be to ask for a referral to a physical therapist to help you with the knee dysfunction.
