Another important function of the menisci is to increase joint congruity by filling in the space between the tibia and the femur where they are not in contact. true or false

True.

Explanation:

The menisci of the knees are semicircular fibrocartilaginous structures consisting of a hydrophilic extracellular matrix containing a network of collagen fibers, glycoproteins, and proteoglycans maintained by a cellular component. The menisci are responsible for more than 50% of load transmission across the knee and increase joint congruity thereby also aiding in fluid film lubrication of the joint.

Meniscus is derived from the Greek word meniskos meaning crescent moon.1 A meniscus is a crescent shaped fibro cartilaginous structure which part divides a joint,2 usually while adding concavity. Menisci (pleural) are present in many joints throughout the body, most notably the knee.
