In the knee, it most often refers to the femoral Trochlea, the groove where the kneecap (patella) glides. Clinicians use the word when describing patellofemoral anatomy, imaging findings, and causes of kneecap instability. It is also used in other joints (such as the elbow), but knee care commonly centers on the femoral Trochlea."}
