Extract
Arthritis of the patellofemoral joint is typically an extremely
debilitating condition and is relatively common. Arthritic changes have been
found radiographically in the patellofemoral compartment in isolation in 13.6%
to 24% of women and in 11% to 15.4% of men in two studies of subjects who were
more than fifty-five and sixty years old,
respectively1,2.
When only patients with symptomatic osteoarthritis of the knee were
considered, the prevalence of isolated patellofemoral disease (in patients
over fifty-five years old) ranged from 5% to
8%2,3.
In a cadaver study of 100 individuals who were more than sixty-five years old
at the time of death, 79% had evidence of patellofemoral osteoarthritis,
although it was not in
isolation4.
