My sister, who also has chronic venous insufficiency, had a total knee replacement at the end of February. Has been doing exercises, going to PT, but after more pains, her PT suggest she start using a cane. Pain in legs and lower back. Finally PT measured her and said her “new knee” leg is 1.6 inches!!! longer than the other one. She is devastated that she is now in worse pain than she was before TKR. She was told to build up the shoe of her shorter leg and find someone to add to the bottom of the shoe as well. Now she can’t walk around barefoot anymore but has to put on shoes to ease the pain even a little. What can she do? Any suggestions?
