good luck Ive got a new acl/pcl and broken tib/fib platoe and that was in 05. Had two clean up surgeries after that. Had a shot in Aug and it worked wonders till about now. I guess now I am 50 I can get a knee, to many years of climbing and skiing has done me in. I feel your pain,pt for 6 months twice to work out bugs. Damn dirt bikes cause more problems!
