The list of knee replacement problems continues to grow

It’s been assumed that knee arthritis patients who undergo knee replacement can expect excellent results. However, the list of knee replacement problems continues to grow and recent research has questioned whether we really know that to be the case. In addition, we also know that a rather large number of patients still have knee pain despite a knee replacement surgery. Now another recent study further muddies those waters and finds more problems. This study looked at patients with arthritis from an injury. What was surprising was that patients with the most knee arthritis didn’t report being better. The patients that seemed to get better were those who had an isolated area that was deformed. The upshot? This is another study that shows how little we know about whether a major surgery like knee replacement can reliably produce positive enough results to offset the significant risk of the surgery. These risks now include a staggering increase in heart attacks and strokes in the months after the surgery as well as a wear particles which can lead to higher blood levels of certain metal ions.
