The diagnosis of radiographic osteoarthritis in one knee or hip likely signals the involvement of the contralateral joint, a cross-sectional analysis determined.
In a patient with moderate-to-severe osteoarthritis in one knee, the odds ratio for having a similar degree of involvement of the other knee was 62.7 (95% CI 42.3 to 93.1), according to Eric C. Sayre, PhD, of the University of British Columbia in Vancouver, and colleagues.
Ouch.
