Which test is used to identify a Plica when there is a painful click?

• A. Clarke Test
• B. Marten's Test
• C. Apley's Test
• D. Mital/Hyden Test

Answer: (D)

A plica in the knee can become irritated and snap or click as the patella moves over the femur. The Mital/Hyden test is designed to provoke that specific plica interaction by placing the knee in a position where the mediopatellar plica is most likely to be entrapped between the patella and femur and then moving or loading the joint to elicit a click. A positive finding—a distinct, reproducible painful click or snap—helps localize the source to a plica rather than to the menisci or a primary patellofemoral problem. Other tests described are less specific to plica: they probe patellofemoral pain with different mechanisms or target meniscal pathology, which doesn’t explain a painful click caused by plica impingement.
