The possibility of having scar tissue removed with arthroscopic surgery is new to me and gives me some hope. I'm very interested in hearing from those who have been through this, either with positive or negative results. I'm slowly losing flexion (down to about 45 degrees now) due to scar tissue build-up after trauma from a TKR (staph infection, subsequent removal of first TKR, followed later with a second TKR). This second TKR (done in 2012) is currently failing (loosening both above and below), which is likely accelerating the scar tissue. I'm 'only' 58 yrs old and was not really liking my options until reading about the arthroscopy possibility. Would love to hear more . . .
