Which clinical test requires the patient to be prone and the knee flexed?

The test that requires the patient to be in a prone position with the knee flexed is the Appley's Test. This assessment is specifically designed to evaluate the integrity of the menisci in the knee joint. During the test, the patient lies prone, and their knee is flexed to a specific angle, typically around 90 degrees. The clinician then applies rotational forces to the tibia while monitoring for pain or an inability to complete the movement, which could indicate a meniscal tear.

Understanding this position is crucial because it allows for proper access to the knee joint mechanics and minimizes the influence of other structures such as ligaments when assessing meniscal function. The prone position helps isolate the meniscal load during the rotation, making it an effective way to provoke symptoms that may not be elicited in other positions.
