Meniscal tear: Damage to a meniscus, the cartilage that cushions the knee, often occurs with twisting the knee.Any form of arthritis or injury may cause a knee effusion. Knee effusion: Fluid buildup inside the knee, usually from inflammation.Caused by aging and wear and tear of cartilage, osteoarthritis symptoms may include knee pain, stiffness, and swelling. Knee osteoarthritis: Osteoarthritis is the most common form of arthritis, and often affects the knees.This is a common cause of knee pain in young people. Chondromalacia patella (also called patellofemoral syndrome): Irritation of the cartilage on the underside of the kneecap (patella), causing knee pain.Numerous bursae, or fluid-filled sacs, help the knee move smoothly. Two C-shaped pieces of cartilage called the medial and lateral menisci act as shock absorbers between the femur and tibia. The medial and lateral collateral ligaments prevent the femur from sliding side to side.The posterior cruciate ligament prevents the femur from sliding forward on the tibia (or the tibia from sliding backward on the femur).The anterior cruciate ligament prevents the femur from sliding backward on the tibia (or the tibia sliding forward on the femur). ![]() Ligaments join the knee bones and provide stability to the knee: Tendons connect the knee bones to the leg muscles that move the knee joint. The smaller bone that runs alongside the tibia (fibula) and the kneecap (patella) are the other bones that make the knee joint. The knee joins the thigh bone (femur) to the shin bone (tibia). The knee is one of the largest and most complex joints in the body.
