Choosing my words carefully has never been my strength I've been known to be vague and often pointless
Glad I found this article. I was beginning to think I was the only one with this ailment. My running club membesr have never heard of this. I had all the same signs as above postings( tight hamstring, then knee on long runs). I was training for my first marathon in December of 2011 when the back of my knee started to hurt. Initially, knee did not start hurting until around mile 14. I ignored it as cramps and ran through discomfort. Then 2 weeks later I could'nt even run a mile. I went and had an MRI done, surgeon saw a small miniscus tear and was reluctant to operate at first. The more we discussed it, the more he wanted to scope the knee. I had surgery in Feb. and miniscuss was repaired along with damaged tissue removed. Surgeon felt the damaged tissue was cause of pain. I started running in April and back of knee still hurt. I now use knee braces and stretch more. I have'nt gone over 7 miles yet, but knee pain is there. After reading these posts I realize my stride and strike have changed due to tight hamstrings. I just finished an olympic tri. and back of my knees were screaming from bike ride. I am going to try and change my stride and stretch more. I also bought The Stick. I wish I would have found this post before surgery, although I did need damage dtissue removed.
I had the exact same symptoms last spring. It turns out that my issues were caused by over striding. I think this stressed the muscles and tendons in the back of my knee and caused my problems. I know it was over strding that caused my problems because correcting the overstriding caused the symptoms to disappear, almost immediately.
I read in another post where Nobby described the proper running technique as a "push" and "swing" motion. I think I was using a "push", "swing" and then a "pull" motion with my leg. The pulling was when I reached out too far with my lead foot and I would then use a pulling force to bring the foot under my center of gravity.
It sounds obvious that we should not run this way, but it is easy to over stride without realizing it. It was not like I over strided by that much, but even a little bit can definitely stress the back of the legs if you are using a pulling force at all. And I would bet that if someone is doing really long runs, that as they tire, they could easily fall into this overstriding.
I am not saying that overstriding is always the cause of these kinds of issues, but it certainly worth considering.
i agree with Zahk78 - i had the same problem, saw an o-surgeon, had the MRI, and it turned out to be a meniscus wear& tear. Luckily, the o-surgeon used to work with NHL teams, and had some decent advise for me: unless its painful all the time, never get the surgery. Its best to use ice therapy, and physical therapy, work on strengthening the muscles around the joint. he said most surgeries arent very successful, as they tend to re-arrange, or move the joint tissue/nerves around, creating false pain signals for the brain - and that's after the surgery. its very tricky. A friend of mine (an avid runner) had the surgery, and he has been in pain for almost 2 yrs now, he cant even walk fast, even tho the MRI reveals a perfectly repaired knee. He still waiting to recover from the false pain signals. i am not doctor, but it helps to talk to multiple surgeons b4 making the decision, and to friends who had the surgery - GL
