Note to moderator: Read the answerline carefully. Damage to three structures in this body part make up (-5[1])O’Donoghue’s unhappy triad. (-5[1])In Osgood–Schlatter disease, (10[2])a painful (10[1])bump (10[1])directly (10[1])below (10[3])this (10[1])body (10[1]-5[1])part (10[4])is caused by (10[2])epiphyseal (10[4]0[1])plate (10[1])tension during growth (10[1])spurts. (10[4])When (10[2])extended (10[2])by the vastus (10[2])medialis, (-5[1])this body part is stabilized by the (10[2])screw-home mechanism and by posterior (-5[2])and anterior (10[1]-5[1])ligaments (10[1]-5[1])arranged (10[1])in an (10[1])“X” shape. (10[4]-5[3])The (10[2])menisci (10[4])of (10[1])this (10[3])joint (10[5]-5[1])improve (10[6])its (10[2])shock (10[1])absorption (10[7])capacity. (10[10])This joint’s (10[1])soft cartilage hardens into (10[1])bone (10[1])at age (10[1])four (10[1]-5[1])and connects (10[1])the femur (10[1])and tibia. (10[3])For 10 points, a common reflex test (10[1])involves (10[1])striking the (10[1])patella of what largest joint (10[1])located between the shin and thigh? ■END■ (10[8])
