Smart, Self-Powered Knee Implants

Knee replacement surgery is the most common joint replacement procedure, with the number of surgeries increasing every year. This surgery is being performed for younger, more active patients who are faced with a dilemma: When they undergo the surgery, they are expected to remain physically active for their overall health but that activity can also wear down the new implant. Often, doctors don’t know if patients are overexerting themselves until they begin to develop symptoms. By that point, the damage to the implant has already been done. For a young patient, going through knee replacement surgery every five or 10 years is a daunting task but finding the perfect balance of activity levels to maintain the integrity of the implant has been equally daunting.
