I am exactly 12 months out from my tkr. It has truly been a miserable year. My knee has been grotesquely swollen and the pain excruciating. My surgeon said he would not do a scope/scar tissue check until the swelling reduced as it would only make things worse. He has been supportive, seeing me every few months, but predicted I was one of a small group of patients who would take 14 months to recover. It appears that he was exactly right. Three weeks ago, something changed virtually overnight. The swelling rapidly decreased and the awful pain I felt on the outer side of the knee turned into the milder discomfort I expected post surgery. So I cancelled my next week appointment: I am not subjecting myself to any more surgical intervention. I moved my recliner out of the living room and life now seems more normal. If things keep progressing this way, I will soon put all this behind me. After a couple of physio based setbacks, I finally ditched the exercises three months ago. My OS agreed saying just do what you want to do, it will be fine. What I believe saved me is riding my stationary bike with zero tension. For the last few months I have consistently done it for half an hour to an hour every day. It was the only activity I could manage without pain and, in the end, I think it helped resolve the adhesion issue.
