Abstract
Synovial plica syndrome (SPS) occurs in the knee, when an otherwise normal structure becomes a source of pain due to injury or overuse. Patients may present to general practitioners, physiotherapists, or surgeons with anterior knee pain with or without mechanical symptoms, and the diagnosis can sometimes be difficult. Several studies have examined the epidemiology, diagnosis, and treatment of SPS. We review these resources to provide an evidence-based guide to the diagnosis and treatment of SPS of the knee.

The synovial plicae are classified as suprapatellar, mediopatellar, infrapatellar, or lateral (►Fig. 1); the medial plica is the most commonly symptomatic one.[2,3,7,9]
A pathological synovial plica can express a plethora of symptoms; the clinical history usually discloses nonspecific anterior or anteromedial knee pain, which has led to the conception of the term synovial plica syndrome.[1,5,6]
Summary
Synovial plica syndrome (SPS) occurs in the knee, when an otherwise normal structure becomes a source of pain due to injury or overuse. While it is an independent pathology and should be differentiated from other causes of anterior knee pain or pain syndrome, there is evidence to suggest that SPS responds well to general conservative measures such as activity modification, exercise therapy, and symptomatic treatment.[5,12] some authors have published findings that do not support conservative management as a successful solution,[2] which may be due a variety of factors, but this
