My wife is experiencing debilitating back and hip problems since a TKR in 2003. Had right knee replacement and her knee flings out to the right when she walks, This causes her to dip to the right putting excessive pressure one the right hip and her lower right back. She is miserable. We consulted with a pain specialist in our area who noticed her wobbly walk. Their conclusion for her chronic pain on that side is the KNEE REPLACEMENT. Never had any hip or lower back pain prior to the replacement. I'm in agreement with Allison...it's a lousy Total Knee Replacement. We're trying to find a way to have the surgery redone by a competent specialist in our area. We met a recent recipient of a TKR at our gym. I asked if he had any physical issues at all after I observed him doing a rigorous workout. His reply was..."none at all". He said his knees work better now than they ever did. His walk is perfectly straight, no out of place bending or wobble! He observed my wife's walk and immediately referred us to his orthopedic surgeon at Union Memorial Hospital in Baltimore, MD. We are following up on his suggestion. This may not go well financially, as we have to prove that the TKR caused the other debilitating issues if we expect our insurance to pay for the redo.. However, I will not give up until she's walking straight and pain free again. People, please do not accept mediocre medical care. Do your research until u get sound answers!
