I'm wearing a dynasplint right now, actually. I've had it for 3 months and it's extremly uncomfortable. But, I was at 20 lack of ROM and I have improved to about 10. But, now I am getting ready to have a M.U.A. It is a knee manipulation to break up the scar tissue so I'm hoping it works although I have my doubts about weather the extension problem is even because of scar tissue of tight hamstrings,tendonitis, and fat pad impingement. Hopefully, youre dynasplint can ive you some relief it has for me I can now at least somewhat walk instead of walking on my toes. Good luck!!
I am kind of going through the same problem, I had 2 surgerys - or scops on my right knee for a torn ligament, first on July 27th 2007, then again on September 19th 2007, and now after what seam like a million tests / knee injections / therapy, that I am still going 2 its not getting any better. After I rest or when I can sleep for more then 3 hours at a time, I get up right back where I started. its been almost 8 months.
Hope u get better.
