There's a persistent myth that knee replacements can predict the weather. Patients often ask if they'll be able to feel storms coming or if the metal will ache when it's cold outside.
The implant itself can't feel weather changes. Metal and plastic don't have nerve endings, so the implant isn't reacting to barometric pressure. What some patients experience is sensitivity in the soft tissues and scar tissue surrounding the joint responding to pressure shifts in the atmosphere. This is similar to how people with arthritis sense weather changes in their original joints.
The good news? This sensitivity typically decreases significantly as you heal and your body adapts to the new joint. Any weather-related discomfort is far less than what you experienced with your arthritic knee before surgery. Most patients find they're much more comfortable overall, rain or shine.
