The precise incidence of plica syndrome is a source of ongoing controversy. The incidence of symptomatic or pathologic plica versus asymptomatic plica is even more debatable. Some authors contend that distribution is regional. Distribution differences based on race or ethnicity may exist.

The incidence of suprapatellar plica has been reported to be as low as 11%; however, one study reported a rate of 89% on autopsy.
