In the Apley compression test, which finding on testing interpretation?

• A. Pain with compression indicates ligament injury.
• B. Pain with distraction indicates meniscal injury.
• C. Pain with compression suggests meniscal injury; pain with distraction suggests ligament involvement.
• D. Pain on both directions rules out meniscal or ligament pathology.

Answer: (C)

The key idea is how the two parts of the Apley test load knee structures differently to help distinguish meniscal tears from ligament injuries. When you press the heel downward and rotate the tibia, you’re loading the menisci against the femur. Pain produced during this compression points toward a meniscal tear. After that, you apply a distraction force to separate the joint surfaces. If pain shows up with this distraction, that stresses the ligaments, suggesting a ligament involvement. So the statement that pain with compression indicates a meniscal injury and pain with distraction indicates ligament involvement is the best interpretation. If pain occurs in both phases, it may indicate combined pathology or a less specific result, but the core idea remains: compression highlights meniscal issues, distraction highlights ligamentous issues.
