1 Structure and Function of the Knee By: Amanda Ball

2 the knee is a hinge joint, one of the types of synovial joints the knee is made of several ligaments, tendons, bones, condyles, cartilage and muscle groups bursa (not shown) cushion the bones Structure

3 the knee must be able to support great amounts of weight cartilage and synovial fluid help the joint to move without friction ligaments guide the knee through its range of motion muscles in the knee provide stability Function

4 the knee is susceptible to many injuries including ACL tears, meniscal tears, osteoarthritis and Osgood Schlatters knee injuries

5 one knee injury common among athletes is a torn ACL (anterior cruciate ligament) causes can include rapidly changing direction, suddenly stopping, slowing down while running, incorrectly landing from a jump, and direct contact collision symptoms include pain, swelling,loss of full range motion and tenderness ACL Tears

6 a torn meniscus can occur when twisting the knee, especially when putting your full weight on the joint symptoms are pain, swelling, stiffness and instability meniscal tears

7 Osteoarthritis (OA) is the most common form of arthritis in the knee OA is the wearing away of cartilage in the joint this is more prominent in middle-aged and elderly people Osteoarthritis

8 caused by overuse occurs at the top of the shin bone and bottom of the knee most common on adolescents especially during growth spurts and in children who play sports symptoms include pain in the knee and tibial tuberosity, which becomes enlarged Osgood Schlatters
