Actually my husband has had 2 artho knee surgeries and 3 full replacements...#1-parts too big, #2 not enough parts in, made it too loose, #3 all hardware and stability good...but he still has severe pain and swelling on the top outer side of his knee with skin discoloration... all has been done within 3 years..last surgery was April 15th....the ortho Dr says everything is fine and he just has to push through the pain....
There should be some reason for the pain. But such things ate only understood once we see and examine the patient. I would recommend u to seek an opinion from other or tho.
