Hi. New to group. I had TKR 18 months ago. Doc put wrong sized implant in and new doc did revision. Correct sized implant in now, but 6 months post op and lots of scar tissue. Knee is constantly swollen and stiff. ROM is good, 125 and 0 degrees on extension. But the scar tissue is causing the swelling. It's rubbing on tissue and causing bleeding. Most is above the knee and caused by the quad tendon being cut and repaired numerous times. Had 40cc's drained off and it was red, fresh bleeding. Knee still looks terrible. Cannot see kneecap or any definition. New doc says only hope is arthroscopic scar tissue removal surgery. This will be my 7th surgery on that knee. Can't decide if the risk of scar tissue returning is worth it. Any similar stories????
