Are a Third of Knee Replacements ‘Inappropriate?’

One third of total knee replacement surgeries in the United States may be “inappropriate,” according to an article published online June 30 in Arthritis & Rheumatism. The findings point to the need for the development of consensus patient selection criteria for the surgery, the authors write.

Daniel L. Riddle, PT, PhD, from the Department of Physical Therapy and the Department of Orthopedic Surgery, Virginia Commonwealth University, Richmond, and colleagues analyzed the records of 205 persons who underwent knee replacement at 4 sites involved in the Osteoarthritis Initiative, a 5-year study partially funded by the National Institutes of Health of patients at high risk for knee osteoarthritis.
