Orthopedic News for Patients

SATURDAY, April 16, 2016 (HealthDay News) -- There could be a downside to knee replacement: As people get more active, their odds for hip and spinal fractures rise, a new study suggests.

One expert wasn't surprised by the finding.

While the exact reason for the increase in hip and spine fractures isn't clear, it's most likely due "to improved mobility and activity as a result of the knee replacement surgery," said Dr. Caroline Messer, who specializes in bone loss at Lenox Hill Hospital in New York City.

"In addition, patients who chose to have the surgery rather than conservative management of osteoarthritis may have been the same individuals who were determined to lead very active and therefore somewhat riskier lifestyles in the future," said Messer, who directs the hospital's Center for Pituitary and Neuroendocrine Disorders.
