I have also used voltaren and it helps a bit but I would recommend therapeutic massage and a therapy pool of 93 degrees. Before and after my TKR the pool has been the most helpful. I searched high and low for a skilled therapeutic masseuse and finally found one and she is great. She as found my glutes sinjoint and hamstrings are very tight thus my problems with sit to stand. My primary doctor just started me on low impact circuit training yesterday because she feels I’ve spent over a year focusing on my knee. The rest of my body’s reserves are low. It is helping.
