Imaging Procedures and Findings
Mild joint effusion is seen. Also noted is a fibrous band extending from medial capsule to the medial side of patella.
A normal structure seen in over half of the population is the medial patellar plica. It is an embryologic remnant from when the knee was divided into three compartments. It is a thin, fibrous band that extends from the medial capsule toward the medial facet of the patella. Suprapatellar and infrapatellar plicae also exist. The medial patellar plica can, on rare occasions, thicken and cause clinical symptoms that are indistinguishable from those of a torn meniscus; this has been termed plica syndrome. An abnormal plica can be removed arthroscopically quite easily.
