Knee: Common Conditions and Treatment Options

The knee is a complex joint consisting of the lower end of the thigh bone (femur), the upper end of the shinbone (tibia), and the kneecap (patella) held together by large ligaments. A meniscus (cartilage pad) provides cushioning between the bones and absorbs shock during motion.

The most common injuries to the knee, especially in athletes, are tears or sprains to the ligaments — the anterior cruciate ligament (ACL) and the medial collateral ligament (MCL) — as well as damage to the meniscus.
