I'm a 23 year old Male, tall and athletic build, who has had 4 knee surgeries. The first two were complete acl and miniscus (both sides of left meniscus) reconstructions and the second two were done in later years to remove further scar tissue and damaged meniscus that continued to get worse. I am now 9 years out from my initial acl reconstruction and my knee couldn't be feeling any worse. I have constant knee pain when sitting with my leg in a bent position, even lying in bed I at times am in discomfort. Standing from seating often causes me to wince in pain. At this point I'm willing to try anything other than a total knee replacement.
