I am new to this forum, but Redwing's story is very comforting to me. After TKA, I was about 75 degrees a week post op, gaining about 5 degrees a week for six weeks - reaching 110 degrees at 7 weeks. now at 11 weeks, I am still at 110 deg - and barely that - when sore and 'cold' - it might be a bit over 90 - 110 is after a workout on the total gym. and about -5 on straight, but I can warm it and get it to zero with some work. I can wait 12-18 months - if that is what it takes, but I surely expect at least 130, since I had almost 140 pre-op, and the other leg is 140. I guess it just takes time. I have time, just don't have patience. I spend 20-30 min a day on stationary bike, and do hours of leg swinging at the desk, stairs, total gym - I do plenty for sure.
