i also posted recently about knee pain. mine was never while jumping but caused me much discomfort afterwards, like when squatting down, or even when trying to sleep if i bent my knees past a certain point. sometimes i would get sharp spontaneous throbbing pains deep and to the outside of my knees. i determined that running was harder on my knees than jumping. i'm no spring chicken and well in my 40's which makes a difference i'm sure and i injured them in an auto accident when 16 and stupid. have not been on my risers in several weeks as my bushings have failed and am waiting for a bearing solution hopefully this weekend. my knees have quit hurting so i guess the damage is not permanent and the pains will work out as i strengthen them up, i've only been with risers for 4 month or so.

Well, everybody's different. You can expect to be working muscles differently than with anything else you have done. For example... I just got what is called an "unloading brace" for my knee, which basically pushs your knee to the inside a little to help keep medial tibia and femur from contacting each other. Anyway.... I wore it bocking and my knee felt great. The next few days I felt like I needed a wheelchair as I was in tremendous pain with every step - but not where the bones meet - so I suspected it was muscular in nature. The pain subside, so I went bocking again. Felt great with the brace on, but again the next day I was crippled. Turns out that the brace causes my leg muscles to work at an ever so slightly different angle than normal -- so they were fine when bocking but then got REAL sore. My leg is now used to it (after a couple of weeks and a heating pad at night) and I don't get the pain anymore.

Some tips... Your knee loop height sounds correct, but if you feel you are hyperextending at times you may just be pushing yourself a little too much after your quad muscles tire. Make sure your knee is held in the loop nice and tight, maybe using a wrap technique like many of us do instead of the crap factory velcro strap. Also, if you find that the knee loop is pressing on the side of your knee, try centering the loop by loosening the hex bolts on one side and tapping the loop tubing either upward or downward to torque it into position.

Naturally, it's hard to diagnose from where I sit. If you don't push too hard when first learning and apply a little warmth to the painful area afterwards, I think your muscles will get used to it.
