Newswise — On Tuesday, December 4 and Friday, December 7, the expert orthopedic surgeons of the Porter Center for Joint Replacement at Porter Adventist Hospital will provide free hip and knee replacements to 14 patients from the Denver area as part of Operation Walk USA 2012.

Operation Walk USA 2012 provides all aspect of treatment – surgery, hospitalization, and pre-and postoperative care – at no cost to participating patients.

Through Operation Walk USA 2012, 109 orthopedic surgeons across the U.S. will provide free hip or knee replacements to more than 200 individuals in 29 states the week of December 3. In Denver, only Porter and Parker Adventist Hospitals are participating in Operation Walk USA 2012, which will restore mobility to 18 patients through the donated time and skill of eight local orthopedic surgeons.

While more than one million hip and knee replacements are performed in the U.S. each year, countless men and women continue to live with severe arthritis pain and immobility because they cannot afford joint replacement surgery.

Arthritic disease is the most common cause of disability in the U.S., affecting approximately 48 million Americans, or more than 21 percent of the adult population. The debilitating pain of end-stage hip or knee degenerative disease often makes working, or completing even the simplest of daily tasks, excruciatingly painful or impossible. Hip and knee replacement surgeries are the most cost-effective and successful of all orthopedic procedures, eliminating pain and allowing patients to resume active, productive lives.

Operation Walk USA began in 2011 following the tremendous success of Operation Walk, an international volunteer medical service organization that provides treatment for patients with arthritis and joint conditions throughout the world. To date, more than 6,000 patients have received new knees and hips through the International Operation Walk.
