A 25-year-old athlete suffers a knee injury affecting the smooth surfaces of the joint where the femur and tibia meet. The doctor explains that the cushioning and smooth movement in this joint are due to a type of cartilage that covers the ends of bones. This cartilage provides flexibility and support while reducing friction during movement. Question:Which type of cartilage is described, and what key characteristic allows it to reduce friction in joints?
