Joint Replacement Revision Surgery

Most joint replacements will function well for the rest of a patient's life. As the number of younger joint replacement patients increases and seniors continue to live longer, however there are times when a joint implant needs to be surgically replaced. These procedures can be performed at St. Joseph’s Hospital in West Bend. 

When It’s Time for a ‘Second’ New Knee or Hip

Dr. Timothy Mullin imageAs the American population ages, the number of people who need knee and hip replacements is increasing exponentially. So, too, is the number of people who require a second knee or hip replacement. “Compared with 2005, the number of revision knee replacements performed annually is expected to double within the next five years while the number of revision hip replacements is expected to double in the next 15 years,” said Timothy Mullin, MD, fellowship-trained orthopaedic surgeon with Froedtert & the Medical College of Wisconsin Community Physicians.

“This is not only because the population is aging, but also because we are performing joint replacements on a younger and more active group of people.”

Dr. Mullin provides comprehensive orthopaedic care. His primary focus is treating knee and hip arthritis with specialization in joint replacement surgery. He has expertise in both primary and revision joint replacement.

Ideally, knee and hip replacements last about 20 years. “After that time, wear and tear on the prosthesis causes the implants to become loose or unstable, which often leads to pain and dysfunction. When that happens, it may be time for a new prosthesis.”

“The results from a revision surgery can be very good, but it is definitely more complicated than a primary knee or hip replacement,” Dr. Mullin said. “That is why we emphasize non-operative measures – including anti-inflammatories and injections – when considering joint replacement surgery for our patients with knee or hip arthritis.”
