Hinge joints allow movement in one direction, as seen in the knees  and elbows and fingers.    FUNCTION: The purpose of joints is to provide movement for the  body.
As the knee is a synovial hinge joint, its function is to permit the flexion and extension of the lower leg relative to the thigh. The range of motion of the knee is limited by the anatomy of the bones and ligaments, but allows around 120 degrees of flexion.any strong ligaments surround the joint capsule of the knee to reinforce its structure and hold its bones in the proper alignment. On the anterior surface of the knee, the patella is held in place by the patellar ligament, which extends from the inferior border of the patella to the tibial tuberosity of the tibia.
