Can surgeons win the fight against osteolysis

In the next 5 to 10 years, orthopaedic surgeons can expect to see a jump in the number of patients who require implant revision surgery, according to Wayne G. Paprosky, MD, FACS, associate professor of orthopaedics at Rush University Medical Center. Although the number of individuals who receive total joint arthroplasty is skyrocketing, the increase in revisions isn’t tied just to population growth. Dr. Paprosky and other attendees of the 2007 AAOS/NIH Osteolysis and Implant Wear Research Symposium delved into the clinical reasons for joint revision surgery and explored issues such as the diagnosis and treatment of osteolysis, the challenges surgeons face during revision surgeries, and the continuing need for research into these complex subjects.
