Tossup
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 this body part is caused by epiphyseal plate tension during growth spurts. When extended by the vastus medialis, this body part is stabilized by the screw-home mechanism and by posterior and anterior ligaments arranged in an “X” shape. The menisci of this joint improve its shock absorption capacity. This joint’s soft cartilage hardens into bone at age four and connects the femur and tibia. For 10 points, a common reflex test involves striking the patella of what largest joint located between the shin and thigh? ■END■
ANSWER: knees [accept kneecaps; accept medial knees or inner knees; accept blown knees; prompt on patellas or patellar tendon until “joint” is read; prompt on meniscus or menisci until “menisci” is read; prompt on anterior cruciate ligaments or ACLs or posterior cruciate ligaments or PCLs or medial collateral ligaments or MCLs until “joint” is read; prompt on legs until “joint” is read; prompt on tibiofemoral joints or patellofemoral joints] (The posterior and anterior cruciate ligaments are named for their cross-shape.)
