Quizplus · Accepted Answer

The Merchant method is the best choice for demonstrating the patellofemoral joint space as it involves a tangential projection of the joint space in a weight-bearing position, allowing for the detection of loose bodies. The other options (Camp-Coventry method, Settegast method, and AP axial projection) do not specifically target the patellofemoral joint space and are not as effective in detecting loose bodies.
