Note to moderator: Read the answerline carefully. Damage to three structures in this body part make up O’Donoghue’s unhappy triad. In Osgood–Schlatter disease, a painful bump directly below (10[1])this (10[1])body part (10[1])is caused by epiphyseal (10[1])plate tension during growth spurts. When extended by the vastus medialis, this body part is stabilized by the screw-home mechanism and by posterior (-5[1])and anterior ligaments arranged in an “X” shape. (-5[2])The menisci of this (10[1])joint (10[2])improve its shock absorption capacity. (10[2])This joint’s soft cartilage hardens into bone at age four and connects the femur and tibia. For 10 points, a common reflex test (10[1])involves striking the patella of what largest joint located between the shin and thigh? ■END■ (10[2])
