I had TKR in late April 2016. I experienced considerable swelling for at least 4 weeks after surgery and limited range of motion. At 10 weeks after surgery, I underwent MUA. At that time my extension was 3 deg and flexation was 90 deg. Due to pain and stiffness in my quad after the MUA, it took about 4 or 5 weeks of PT to get the range of motion I had before MUA. I stopped PT in August 2016 but continued to do the same excercises at home on my recumbent bike and on the weight machines at the Y. At that time I had -3 deg extention and 95 deg flexation. I could not go down stairs normally unless they were 5 inches or shorter. I had to put my sock on while keeping my foot on the floor and bending at the waist. Now a year after surgery, I am seeing some progress. I can go down stairs by rotating my body towards the operated knee and can put on my sock by raising my knee on the side of the bed. I have been able to move the seat forward three positions on the recumbent bike.
Have others had similar experiences? Can I expect further improvement in range of motion? Is there any evidence that stiff knee after surgery is associated with anticoagulent use? I was using Xarelto at the time of surgery.
