Five years ago, Dr. Ira Kirschenbaum, an orthopedic surgeon in the Bronx who replaces more than 200 knees each year, would have considered it crazy to send a patient home the same day as a knee replacement operation.
And yet there he was this year, as the patient, home after a few hours. A physician friend pierced his skin at 8 a.m. at a Seattle-area surgery center. By lunch, Kirschenbaum was resting at his friend’s home, with no pain and a new knee.
“I’m amazed at how well I’m doing,” Kirschenbaum, 59, said recently in a phone interview, nine weeks after the operation.
What felt to Kirschenbaum like a bold experiment may soon become far more standard. Medicare, which spends several billions of dollars a year on knee replacements for its beneficiaries — generally Americans 65 and over — is contemplating whether it will help pay for knee replacement surgeries outside the hospital, either in free-standing surgery centers or outpatient facilities.
