Why Joint Replacements Can Affect Balance
Many people are surprised to learn that balance can temporarily change after a total knee or hip replacement.
While these surgeries are remarkably successful at reducing pain and restoring mobility, they also change some of the sensory information traveling from the joint to the brain.
Your natural joints contain specialized nerve endings called mechanoreceptors within the joint capsule, ligaments, and surrounding tissues. These receptors continuously inform the brain about joint position, movement, and load—a sense known as proprioception, or your body's awareness of where it is in space.
After a joint replacement, some of those structures have been altered or removed. As a result, the brain receives different sensory information than it did from the native joint. It's one reason some people say, "My new knee doesn't quite feel like my own."
The encouraging news is that the brain is remarkably adaptable.
Through neuroplasticity, the nervous system learns to interpret new information and develop new movement strategies. Purposeful balance training, strength exercises, and varied movement challenges help the brain recalibrate, improving confidence and restoring efficient movement.
A joint replacement changes the hardware.
Physical therapy helps update the software.
