“…The mediopatellar plica test of the knee joint performed in a similar way to the posterolateral radiocapitellar plica test proposed by the present study has been presented and conducted for diagnosis of pathologic mediopatellar plica in the knee joint. [3,20] According to the previous studies [21–23] consisting of a small number of patients, mechanical symptoms such as snapping and catching have been highlighted as a pathognomonic finding. Clarke [23] first described elbow plica of the radiohumeral joint in 1988.…”

“…Kim and colleagues in 2004 introduced the mediopatellar plica test, a novel clinical test to predict pathologic mediopatellar plica syndrome. 28 The patient is examined supine, and manual pressure is applied to the inferomedial patellofemoral joint that is expected to elicit pain. For the test to be considered positive, the tenderness is expected to be diminished once the knee is flexed to 90 degrees.…”

Synovial plicae are vestigial folds of synovium in a joint, most widely recognized in the knee and also in the elbow and hip joints. The most commonly shared theory on the origin of plicae is that they are the remnants of the membranes that divide the synovial cavitations during normal joint development. Synovial folds do not generally cause any symptoms. However, they can become inflamed, thickened, fibrosed, and also impinged in the joint, leading to mechanical symptoms and chondral damage. This article presents an overview of the embryological origin of plicae, their anatomy, pathologies, and appearances on imaging. We also discuss the lesser known plicae in various other areas.

“…Kim et al also described a test to diagnose medial plica syndrome. The mediopatellar plica test (MPP test) is conducted with the patient supine and the knee extended (Kim et al,2004; Kim et al,2007). The test is performed by applying manual force to the inferomedial portion of the patellofemoral joint and flexing the knee to 90° (Kent,2010).…”

“…The test is performed by applying manual force to the inferomedial portion of the patellofemoral joint and flexing the knee to 90° (Kent,2010). The test is defined to be positive when the patient experiences pain with the knee in extension and the pain is eliminated or reduced with the knee in flexion (Kim et al,2004; Kim et al,2007). The sensitivity and specificity of this test as compared to arthroscopy were 89.5% and 88.7%, respectively, with a diagnostic accuracy of 89.0% (Kim et al,2007).…”

Knee pain is a very common complaint seen in the clinical setting. A torn medial meniscus, osteochondral defects, inflammation, or an irritated medial plica are some of the most common causes of medial knee pain. Plicae are synovial invaginations that are believed to be remnants of the embryological development of the knee. They have a potential to become inflamed and symptomatic. Diagnosis of medial plica syndrome involves physical exam and imaging studies, but the current gold standard is arthroscopy and therefore a definitive diagnosis cannot be made until surgery. As such, medial plicae are the most commonly missed diagnoses in the knee as it is purely a clinical diagnosis. Medial plica syndrome can be treated with physiotherapy, corticosteroid injections, or surgery. Overall, good outcomes have been seen following diagnosis and treatment of medial plica syndrome, with patients returning to their preferred levels of activity. This article reviews the topic of medial plica syndrome.
