• A. Valgus overload test
• B. Dreyer sign
• C. Lift off test
• D. Craigs test

Answer: (A)

Assessing patellofemoral joint function under load to identify maltracking and medial knee pathology. When a patient reports snapping and grinding at the knee with medial patellar pain, you want a test that places the patellofemoral articulation under stress and can reproduce symptoms related to the medial structures involved in tracking. The valgus overload test does just that by applying valgus stress through the knee as it moves, which increases compressive and shear forces on the medial compartment and the patellofemoral joint. If this loading reproduces or worsens the pain, it suggests a medial knee pathology contributing to the patellofemoral symptoms and helps confirm a maltracking or structural issue under functional load. The other tests are less directly informative for this presentation. The Dreyer sign can indicate patellofemoral or plica-related issues but doesn’t emphasize the dynamic medial load the knee experiences during movement. The lift-off test is not specific to patellofemoral pathology, and Craigs test focuses on femoral anteversion rather than the patellofemoral mechanism or medial knee pain during functional loading.
