Thanks for your interesting posts.

Not being a medical person, I had to look up 'eccentric' exercises, and as I suspected it does not mean I should embellish my exercises with extravagant flourishes and wear an outrageous outfit...

It means strengthening exercises that involve extending the muscle e.g. by lowering a heavy weight - am I right?

And you say that these exercises will rerrange the fibres in the tendon to make it stronger etc - is that about right in layman's terms? I take it that whilst my tendon is sore, it doesn't necessarily mean it is thinner and more prone to snap? Obviously, that wouldn't be good.

I have bought a patellar tendon strap and will use it. I used it last time although I had to go off the field with my bad knee, but I suspect that was because I was doing intense exercise after months of not very much.

It makes sense to me that I should gradually build up intensity and hopefully that will mean my tendon will recover.

Interesting theory about the extra vascular presence in tendinosis, and how the eccentric loading can reduce the vascularity.
