Hi everyone! I had my first TKR on August 28th and everthing has gone really well. I had a 115 ROM at 4 weeks and at 5 1/2 weeks was walking without any aid. I have had the sleeping issues like a lot of people but at 8 weeks without any warning I get very down. I had the weepyness etc the first couple of weeks but at 8 weeks I just don't understand it. How long does this last?The only pain meds I take are tylenol ES at night. I am out doing things, back to my hobbies and in general doing great, except that at least once a week I get very down and I don't know why. Has anyone else experienced this 8 weeks out and how long should I expect it to last. BTW I am off to the Orthopedic Dr. tomorrow to get the date for my other TKR (right knee).
