A boy fell down while playing and severely injured his knee, making it hard to walk. Which two connective tissues are most likely to be involved in this injury?
Ligament and Cartilage
The knee is a synovial joint. Its bones are held together by ligaments, and the ends of the bones are covered by smooth cartilage that cushions the joint.
Ligaments are elastic connective tissue joining bone to bone; a fall that twists the knee commonly sprains or tears them. Cartilage (e.g. the menisci and articular cartilage) can also be torn, which makes walking painful and difficult.
Areolar tissue is a packing tissue found under the skin and around organs; it does not stabilise the joint.
Tendons join muscle to bone and blood is a fluid connective tissue that transports materials — neither is the main structural tissue of the knee joint.
Adipose tissue stores fat, and bone fracture is a different injury from a joint injury that hampers walking at the knee.
Hence, the answer is Ligament and Cartilage.
