Because I inquired about MUA, thought I would post a follow-up. Left TKR was on April 16. On May 24 ROM was 70 and surgeon thought a MUA might be needed. I saw my surgeon on 6/17 for x-rays and evaluation, and he was excited that in three weeks I had gone from 70 degrees without assistance to 100-105 degrees without assistance--and he saw no reason for MUA. He told me that before the surgery he measured me at 105 (no shock there--I've had terrible ROM due to pain for a number of years) and 130 after the surgery. He was confident that I will continue to gain more ROM over time. I'd like to get to 110-115--that's my goal. I see surgeon again in two months, and he gave me the go-ahead to see a massage therapist for myofascial massage and to resume my weekly sessions with my Pilates instructor (who works with lots of knee/hip patients). I'm reducing my PT visits from 3x each week to 2x, and continuing to swim/do water exercises daily and do my dry land exercises at home. I have the tight band feeling sometimes, sometimes I feel a tight and tender spot right behind the knee when I walk--seems like recovery for many weeks/months after a TKR includes varying types/degrees of pain/discomfort. Trying to take each day as it comes. Of course the right knee is "barking" more--especially on steps, when I do mini-squats, etc. It has to hang in there until I get the left one sorted out!
