What is the main purpose of the Hughston's Plica Test?

Hughston's Plica Test is specifically designed to identify the presence of a plica in the knee joint. A plica is a fold of synovial membrane that can become irritated or inflamed, often leading to pain and dysfunction. During this test, the examiner assesses for the presence of a medial plica by applying specific movements and palpation methods to elicit symptoms indicative of plica syndrome.

This test is not focused on other aspects of knee function, such as joint stability, iliotibial band interactions, or patellar positioning. Each of the other options describes different tests or assessments related to knee pain, but they do not address the unique purpose of identifying the plica specifically. Thus, the main purpose of the Hughston's Plica Test is accurately reflected in the identification of a plica's presence.
