Answer

Little literature exists on lateral plica. Most of this literature is Japanese, and few cases have been reported in English. [21]  The incidence of this kind of plica is lower than 1%.

Dupont et al found some type of inferior plica in 65% of their 200 dissected cadaveric knees. They stated that it was the most frequently found plica. In their review of the literature, infrapatellar plica was most common in some studies but not in others. [7]
