After several years of constant pain, a different doctor found the my knee caps had been replaced
with over-sized ones during the first (knee replacement
) surgery, and they had ripped out the stitches in the muscle, causing the knee caps to rub against the ruptured muscle. A second doctor discovered the oversized knee cap, and replaced one. However, the pain in both knees continues, growing daily, and I can now hardly walk (must use walker) or stand. Doctor says he can do nothing more for me.
