Final answer:
True. The knee joint and the knee joint complex are different.
Step-by-step explanation:
True. There is a difference between the knee joint and the knee joint complex. The knee joint refers to the specific articulations between the femur, tibia, and patella that allow for flexion and extension of the leg. On the other hand, the knee joint complex includes not only the articulations but also the surrounding ligaments, tendons, and menisci that provide stability and support to the joint.
